Danish green energy giantrsted CEO Henrik Poulsen has resigned after an eight-year tenure. rsted is now the worlds biggest offshore wind developer. It recently installed its 1,500th offshore wind turbine, in announced on June 11.

Poulsen will leave rsted by January, the company announced yesterday. The company is now searching for a replacement. He was previously an executive at McKinsey and Lego.

Poulsen said [via the Financial Times]:

Its been an incredible ride over the past eight years, and I have a tremendous amount of affection for Orsted, its vision, and not least its people.

Weve transformed a Danish utility predominantly based on fossil fuels into a global leader in green energy, which was ranked as the worlds most sustainable company earlier this year.

rsted plans to double its wind capacity in the next five years to 20GW. It employs almost 7,000 people worldwide, and had revenues of around $10.3 billion in 2019.

The Financial Times reports:

The companys stock has risen more than 70% since the beginning of last year, brushing off a dip in valuation inflicted by the pandemic and giving it a market capitalization of roughly $48 billion.

The Danish green energy company is growing its onshore wind business, too.

As Electrek previously reported on April 8, in 2013, rsted announced it would stop developing onshore wind to concentrate on offshore wind, but in 2018, it returned to onshore wind development with the acquisition of Lincoln Clean Energy. It completed its largest onshore wind farm, in Texas, in April.

rsteds onshore operational installed capacity has increased to 1.3GW. The company intends to reach 5GW installed onshore capacity by 2025.

It aims to reach 99% green energy production overall by 2025.

Poulsen transformed what was a fossil-fuel company known as Danish Oil & Natural Gas into Orsted, which is now known as the most sustainable company in the world.

He also proved that green energy can be profitable. Lets hope he keeps his hand in the game, as he has achieved remarkable things for the green energy sector and the environment at large.

CEO of worlds largest offshore wind developer resigns - Electrek

As our nation cautiously reopens and our economy begins to recover from the COVID-19 pandemic, the thought of a summer road trip has never seemed sweeter. Just having the freedom to take to the road and explore our beautiful country has an exciting, renewed significance for many of us right now. Once we get the green light and before our journey begins, however, we'll need to fill up our gas tanks.

Louisiana's offshore oil and gas industry provides fuel that makes our trips possible, as well as hundreds of thousands of well-paying jobs that fuel our local, state and national economies. Now, the industry needs help to survive and continue to fuel our nation and economy long after this crisis has passed.

The COVID-19 pandemic brought the global economy to its knees this spring, shuttering businesses, suspending travel and cutting worldwide demand for oil and gas to the lowest levels in modern history at a time when production levels were surging. U.S. crude oil production was, in fact, at an all-time high in early 2020, breaking records and contributing to our nation's new role as a net oil exporter. Louisiana's local companies and infrastructure have supported the production of nearly 20 percent of America's oil supply, 45 percent of U.S. petroleum refining and 52 percent of our nation's natural gas processing.

Then, that historic peak seemed to evaporate overnight as the pandemic extended its reach, demand began to drop, and a price war between Saudi Arabia and Russia contributed to a glut in the oil supply. We watched oil prices plunge to less than $20 a barrel and analysts predict a 20-percent decline in global oil demand in 2020, still too much for a 10-million-barrel-a-day OPEC production cut to overcome. Global oil storage reached its capacity.

The impact on Wall Street has been devastating, but the impact on America's future domestic oil supply is even more alarming. This economic crisis truly threatens the survivability of our strong domestic offshore oil and gas industry, thousands of small businesses who service offshore production, and the hundreds of thousands of men and women whose jobs are linked to oil and gas production. We must save America's offshore oil and gas industry.

On April 2, LMOGA appealed to President Trump to implement measures to help domestic oil and gas producers and local businesses survive the crisis by putting them in a position to recover and continue fueling our nation and the world once demand and supply stabilize. Without emergency policy measures, producers may have no choice but to shut in wells, accelerate layoffs and cancel contracts totaling millions of dollars with local service companies. Without preemptive federal action, the economic domino effect will be long and brutal, and our future domestic energy supply will be at risk.

One of the measures promoted by LMOGA is the temporary reduction or suspension of royalty payments on federal offshore leases to ensure a robust energy industry remains viable during and after the current crisis. A viable industry is not only good for the economy and our energy supply, but for coastal restoration as well, because production generates federal funds for restoration projects. The U.S. Secretary of Interior has authority to reduce royalty rates for economic purposes, and LMOGA has strongly advocated that President Trump, Secretary of Interior David Bernhardt and Congress make this temporary cut to boost production and future royalty revenues.

LMOGA requested actions including a three-year extension on federal leases in the Gulf, extensions for decommissioning wells, and the protection of pipelines and other infrastructure if limits to storage capacity necessitate well shut-ins.

I am convinced that our global economy will rebound once the pandemic threat has diminished, and then demand for oil and gas will soar. We need to ensure our domestic offshore oil and gas industry survives to meet tomorrow's challenges and continues to fuel our gas tanks, the national treasury, and jobs for men and women everywhere for decades to come.

A Louisiana-based offshore services firm and naval architects plan to build a new superfeeder class of vessel to provide offshore wind energy developers a Jones Act-compliant system for transporting turbine components from U.S. ports to installation sites.

The 408x131x16.4 SuperFeeder will be a fully DP-2 dynamic positioning vessel, propelled by three diesel-electric 2,500-kW Z-drives and two 1,200-kW tunnel bow-thrusters, and capable of 10 knots cruising speed while fully loaded with turbines, foundations and blades, according to 2nd Wind Marine LLC, Galliano, La.

Developed by naval architects MiNO Marine LLC, Jefferson, La., the design is planned for two vessels to be built simultaneously, completed in 2021 to work on more than a dozen wind energy areas leased by developers off the East Coast.

They will each be capable of transporting one complete set next-generation wind turbine components from U.S. ports to offshore wind farm sites, enabling optimized construction throughput and the most efficient utilization of non-Jones Act compliant wind turbine installation vessels, according to a statement from the companies.

With early U.S. wind projects dependent on U.S. feeder barges carrying components to foreign-flag European wind turbine installation vessels and the first Jones Act WTIV still a few years away the time is right for the superfeeder concept, according to Joseph A. Orgeron, business and technology developer for 2nd Wind Marine.

Orgeron worked in 2015-2016 with Deepwater Wind (since acquired by wind developer rsted) to bring Gulf of Mexico liftboats north for construction of the Block Island Wind Farm, the first U.S. commercial offshore wind project off Rhode Island. Hes an advocate for the skills and experience that Gulf of Mexico offshore operators can adapt to the nascent East Coast wind industry.

According to the companys own mission statement, 2nd Wind was created as a vessel development, erection, and operations firm that intends to manage the design, finance, construction and ultimate operation of a two purpose-built Jones-Act coastwise compliant vessels capable of transporting (or feedering) of large, next-generation offshore wind turbine components from U.S. marshalling ports out to awaiting installation vessels during installation phases and perform specific O&M tasks in the post-installation market.

The vessels power systems will be primarily diesel-electric with medium speed Tier-IV engines. The hulls and superstructures will be configured to accommodate the coming generation of 12-megawatt and larger turbine parts Orgeron calls the design future-ready.

The design has the house offset asymmetrically to the port side, allowing more bow deck space to accommodate larger vertically stacked blade racks. Below decks will accommodate up to 60 persons, counting 20 crew and 40 offshore workers, in single and double berthed, MLC-2006 compliant staterooms.

The cargo deck rated to transport, and jack up with, 4,000 metric tons has a double deck, so changes in grillage can be easily facilitated without concern to tank and void spaces below. Each vessel is intended to carry a complete next-generation turbine set, including tower, generator nacelle and blades.

A unique Liebherr-designed crane, installed around a jacking leg with an offset-pedestal, will allow access to more than 95 percent of the vessels cargo deck space. Its lifting capacity will be up lifting each component of next-generation turbines from quayside to the cargo deck. With an extended boom variant, the crane will enable operators to change out blades at sea in the wind turbine arrays.

MiNO Marine developed its designed hull form through extensive engineering analysis using computational fluid dynamics (CFD) methods to yield an efficient hull form suitable for a wide range of offshore operating conditions while also minimizing potential for flow induced drag.

U.S. shipyards have been engaged and are currently evaluating the design and preparing construction cost and timeline estimates, the companies said.

Speaking at the International WorkBoat Show in December 2019, Orgeron likened the potential of U.S. offshore wind for offshore operators to the cusp of offshore oil and gas a half-century before.

Probably 40, 50 years ago with the rise of the Cajun mariners, my dad was looking in the Gulf of Mexico and saw a great opportunity when the oil and gas companies said how much they were going to spend, said Orgeron. With the Block Island project, I saw then there was so much interest in Gulf of Mexico vessels, he said. There was so much more there for Gulf of Mexico operators to look into.

Join us for a live webinar on Thursday, June 25, where well discuss many of these topics and also investigate what the vessel supply chain capabilities currently are, what building a future-ready offshore wind vessel looks like, how creative ideas will ensure timely development and investment, and lastly how characteristics of the northwest Atlantic working environment differ from the European model and how that will affect vessel design and performance.

North Carolinas objectionto WesternGecos proposed Bureau of Ocean Energy Management permit to conduct a geological and geophysical seismic survey for oil and gas exploration in the Atlantic Outer Continental Shelf has been overridden.

The decision signed byU.S. Under Secretary Of Commerce For Oceans And Atmosphere Neil Jacobs was announced Monday.

The state Department of Environmental Quality voiced Monday its disappointment with the decision to override North Carolinas Coastal Zone Management Act consistency objection to WesternGecos proposal to conduct geological and geophysical, or seismic, surveys off the North Carolina coast.

WesternGeco appealed North Carolinas findinglast yearthat its proposed survey was inconsistent with state enforceable policies because of adverse effects to recreational and commercial fisheries. The decision to override the states objection to the proposed survey was announced Monday.

The effect of this decision is that the state Division of Coastal Managements consistency objection no longer prohibits the Bureau of Ocean Energy Management from issuing a permit to WesternGeco. Numerous studies, including several new studies completed in the last few years, indicate the proposed seismic testing poses an unacceptable threat to North Carolinas marine life and its coastal recreational and commercial fisheries, according to NCDEQ officials.

This proposed seismic testing for oil and gas exploration has no place off our coast, said NCDEQ Secretary Michael S. Regan. Our coastal resources are too precious to risk from these proposed activities. We stand with all of the coastal communities who have made their opposition to the proposed seismic testing and offshore oil and gas clear.

North Carolina can appeal the decision to the federal courts and the state said it is reviewing next steps.

Coastal leaders and state officials have signedsigned a resolutionto oppose seismic testing and the offshore drilling that would follow.

WASHINGTON, D.C. Since its launch in May 2019, more than 6,200 subscribers have signed up for the BSEE!Safe text notification service.

The Bureau of Safety and Environmental Enforcement (BSEE) is the first regulator in the world to provide critical safety information directly to workers via text message.

BSEE Director Scott Angelle said: Offshore safety was the driver for this initiative. Steadily increasing subscriptions to the BSEE!Safe text messaging service demonstrates BSEEs leadership in pioneering ways to reach offshore workers.

The BSEE!Safe texts contain links to the bureaus published Safety Alerts and Bulletins which include safety recommendations resulting from incidents and near misses on offshore oil and gas facilities.

More than 120,000 text messages have been sent since its inception, according to BSEE.

BSEE!Safe is an efficient, timely way to communicate directly to the men and women who wear the hard hats and steel-toed boots; who kiss their families goodbye and set out to the OCS to do the hard work of fueling our nation, said Angelle.

Subscribers maintain their own contact information and can opt out of the service at any time.

In addition, the bureau has issued 41 Safety Alerts and Bulletins since the launch of the service.

BSEE!Safe text notification service hits milestone - Offshore Oil and Gas Magazine

It didnt take long for the newly-unveiled biggest beast in the offshore wind jungle to make a big mark in the market.

Within a week of its launch, Siemens Gamesas 15MW machine was being lined up for deployment at the up-to 1.1GW Hai Long 2 project off Taiwan for developers Northland Power and Yushan Energy. The new 14MW giant is also in the frame for the 2.6GW Coastal Virginia project in the US, bringing the worlds biggest turbine to whats set to be Americas most ambitious offshore wind project to date.

The relentless scaling-up of offshore wind was central to another Recharge exclusive this week as we reported how Germanys Aerodyn is taking blades to a new level with a 111-metre design, a full three-metres longer than those on the new Siemens Gamesa SG14-222DD.

As the world recovers from a historic economic shock, green energy pacesetters like Vestas can lead the rebound and make sure the world is ready to face the next crisis climate change.

That was the message from the Danish wind giants CEO Henrik Andersen in an exclusive opinion column for Recharge this week setting out whats at stake as the EU and other policymakers lay their plans for economic stimulus packages.

Vestas itself was yet again confirmed as the wind sectors market leader by another industry study, while the OEMs global reach was underlined by its latest success in Vietnam.

The US wind market has reason to celebrate this week as the federal government confirmed projects will get more time under tax credit incentive programmes to take account of disruption caused by the Covid-19 pandemic.

Thats a relief to a industry that was facing big pressures on its supply chains and people although, as a Recharge analysis explained coping better than many sectors of the US economy.

US offshore wind wasnt part of the relief measures but marked its own milestone when construction work began at the first project in US federal waters, with first foundations now installed at Dominion Energy and Orsteds 12MW Coastal Virginia Offshore Wind pilot site.

On the downside, another US offshore wind plan the Icebreaker project on Lake Erie, Ohio declared itself stunned at a consent decision it claimed could make the long-percolating development unviable.

Newfoundlanders and Labradorians rely on industries such as our offshore oil and gas every day to keep the bills paid and food on the table.

Due to the ongoing pandemic for many, incomes have been cut drastically. I question whether the federal government has done enough to support cash-strapped Newfoundland and Labrador during these unprecedented times?

The short answer is no.

Canada needs to offer incentives for offshore exploration, right here off the coast of our province. The argument can be made that the price of oil is low and why develop more when the demand isnt there but look at it this way: the world needs oil and gas, Canada needs oil and gas.

We need to produce more of our own oil and gas, not rely on other countries such as Saudi Arabia.

Why? Because we use oil and gas every day to fuel our vehicles, it provides a source of electricity, its used as stove oil heat our homes the list just goes on and on.

Along with the direct use of oil and gas in our lives, this industry employs thousands, both directly and indirectly here in the province.

For example, our industry employs SAR techs, welders, mechanics, cooks, deckhand, sea captains, drillers. Onshore we see secretaries, HR staff and assistants employed at Noia or businesses like Cahill or Atlantic Towing, the list just goes on and on.

Businesses are going under, they are downsizing operations and pulling up stakes here in our province this just can't continue.

Our offshore oil and gas is the single greatest contributor to our economy, we need it to prosper and be explored to attain the best outcome. To achieve this outcome which would allow our province to return to surplus and balance our budgets, we need to renegotiate our Atlantic Accord along with having our elected officials in Ottawa putting Newfoundlanders and Labradorians best interests first, not Ottawa's.

Why not allow our offshore to be eligible for the Atlantic Investment Tax Credit? Its initiatives like these that will get boots on the ground and people back to work.

It has been done before, it can be done again; It is time for Newfoundlanders and Labradorians to finally get a hand up, not a handout.

LETTER: Ignoring our offshore oil and gas industry will not get our province back on track - SaltWire Network

By Kieran Hanley

The success of our offshore oil and gas industry is critical to Newfoundland and Labradors economy. We know this. But what may be surprising is that it is also a centrepiece of the provinces clean growth strategy.

Lets be clear: urgent action is required worldwide if we are to meet the objectives of the Paris agreement. But such fundamental changes in the economy, its infrastructure, and the habits of consumers that will be required will not happen overnight. Oil and gas represents upwards of 60% of global energy consumption. Demand for it doesnt just go away. Objectively, if the world has any hope of meeting greenhouse gas emissions targets, changes within the oil and gas industry have to be part of the solution.

This is the transition that we keep hearing about, and Canada can play a major role in helping to lead this shift. Its offshore industry puts us in an excellent position in this regard. We are lucky in that the type of oil in our offshore is the least impactful from an environmental perspective to process. And the GHG intensity of our operations are 30 per cent below the international average. This is to say that it is within our reach to set a global standard for the decarbonization of the industry. In this time of transition, reducing global emissions by providing the world with the most environmentally sound oil is a valuable contribution to the fight against climate change.

And there are substantial economic and clean growth prospects associated with that, with immediate opportunities for investment and improvement. An offshore wind farm Canadas first could lower our offshore assets.

Ditto for the abundance of clean energy we have flowing from Muskrat Falls. Either would achieve significant emissions reductions and represent major clean growth projects that would get people back to work and propel our industry into a new era of low-carbon operations.

Beyond such major projects, there are lots of things we can do to throughout the industrys vast supply chain. Zero-emissions supply vessels. Electrified ports. Major energy efficiency initiatives. Digitalized and remote operations. These activities represent clean, green economic growth. They are enormous cleantech research, development, and commercialization opportunities that can be exported worldwide and expanded through different ocean industries once commercialized.

We know this because we have already seen the pattern play out.

Because of the high environmental standards our offshore industry and its stakeholders have collectively put in place and adhered to, we have become a centre of excellence in the provision of products and services that help us characterize and monitor the environment. Our province is home to an unnaturally high number of SMEs with world class technologies using lasers, radar, sonar, and hi-def video in the skies and under the water that help us understand whats happening in the ocean. This expertise, which we export all over the world, would not have been developed without the offshore oil and gas industry. This past success is indicative of the opportunities before us if we embrace becoming the least carbon intensive oil producing region on the planet.

Further, you might have missed it but Newfoundland and Labrador has committed to achieving net zero carbon emissions by 2050. The offshore industrys support of this policy has the potential to dramatically alter the landscape of (and diversify) our economy. With new resources to finance a slew of new major emissions reduction projects, Newfoundland and Labrador could rapidly transition into one of the cleanest jurisdictions in the world with one of the most advanced clean growth economies.

But none of this will come to pass without immediate support for Canadas offshore oil and gas industry. A future without it would be very grim for Newfoundland and Labrador indeed, and would extinguish our best chance at becoming an international clean growth leader.

We are in the midst of an energy transition.

Canada has an opportunity to be a leader in that transition. The solutions we develop here can set the global standard, and our expertise and technologies can be exported worldwide for the betterment of the planet and our own economy.

This a worthy pursuit that we can all support.

Kieran Hanley is the executive director for the Newfoundland and Labrador Environmental Industry Association (NEIA). He writes from St. Johns.

The complete paper discusses the systematic approach adopted by a service company to achieve the goal of safely abandoning wells offshore southwest Brazil with different completion types using light workover vessels. Having determined the abandonment methodology, service company personnel developed processes and procedures to reach the objective that included advances in coiled-tubing (CT) rigup procedures and use of a real-time telemetry system.

The use of a CT real-time telemetry system enables accurate setting of a through-tubing inflatable device system (T-TIDS) by monitoring the necessary downhole parameters in real time. The paper presents a case study wherein sensors [such as a casing collar locator (CCL) to perform depth correlation before setting the T-TIDS and placing cement plugs, a pressure sensor to monitor the T-TIDS setting, and a CT internal pressure sensor to help ensure all cement was pumped out of the CT] were used in real time to verify that well barriers were set in place, contributing to successful well abandonment. Real-time data collection proved to be the most-effective methodology for running critical equipment, thereby saving overall time and cost.

The decision for permanent abandonment of a well is not always easy. In Brazil, the National Agency of Petroleum, Natural Gas, and Biofuels (ANP) has established a compendium of rules for oil companies that extract and produce oil, gas, and derivatives. This involves a group of barriers known as CSB, which is a set of one or more elements with the objective of preventing the unintentional flow of fluids from the formation to the external environment and between intervals in the well considering all possible paths. The CSBs aim is to guarantee the isolation of intervals with current and future flow potential. Cement or other material with similar performance must be used as barrier elements.

Achieving a unique solution is dependent on having up-to-date information regarding the wellbore diagram, reservoir, history, well location, CT-performance capability, surface equipment, well-control equipment, and proposed layout. Fig. 1 illustrates the design of the 3D wellbore graph generated with modeling software.

The well discussed in this work contains deposits of asphaltene and sand-accumulation debris. For the operator to perform a plug-and-abandon (P&A) intervention, an effective solution to provide reliability safely is necessary to avoid worsening the well condition and delaying the intervention. The service company offered experienced personnel and engineering capabilities, a customized program for job-specific requirements, the CT package, and reliable processes and advantages compared with heavy workover units. Included as part of those advantages is a variety of bottomhole-assembly (BHA) tools that can be deployed in the well with the capability to be customized, working together with wireline operations and the robust management safety system.

T-TIDS are used in applications where the BHA must pass throughout a wellhead restriction or cased-hole restriction and must be installed at inner diameters larger than such restrictions. They can be used as remedial or completion applications. A T-TIDS was used to perform P&A applications in the operations discussed. T-TIDS applications include thefollowing:

Well-temperature variation before and after the T-TIDS installation influences the success of the operation. Once seated, temperature changes also will affect pressure inside the T-TIDS. Increased temperature can lead to overpressure until bursting, while decreased temperature can lead to falling or slipping of the T-TIDS. The pressure gradient is calculated during operational design according to the expansion of the T-TIDS pressure at which it will be installed and the well temperature before and after installation.

The design of service (DOS) is a requirement that helps ensure that the job purpose will be achieved. The DOS is prepared by an operational engineer on the basis of well data (wellbore diagram, reservoir, history, and well location) and an expected solution. The DOS presents topics related to customized intervention operations. Moreover, all BHA tools (including a contingency plan) necessary to perform the operation are included. In case of adjustable parameters during the operation, as per some variation of the well conditions or operator request, one update should be performed with all parties in agreement. The service company used modeling software to help the engineer customize job execution.

The BHA is the tool component conveyed by CT to reach the target and perform the operation. For this operation, it was used in addition to the basic tools such as a CT connector, a double flapper check valve, a disconnector, a rotary jetting tool, telemetry sensors, and the T-TIDS.

The use of a CT real-time telemetry system into the BHA enables accurate TTIDS setting through real-time monitoring of the necessary downhole parameters. The sensors used at the BHA in this well included internal/external pressure, temperature, tension-compression, and a CCL. The CCL was used to perform depth correlation before setting the T-TIDS and placing the cement plug with the real-time internal/external pressure signal to monitor T-TIDS setting and managing the CT internal pressure assist to help ensure that all cement was pumped out of the CT.

Before running the CT BHA with the TTIDS, a jetting and drift process was used to remove present incrustations inside the production tubing to help ensure successful T-TIDS setting. In this single run, three objectives are achieved in just one trip in/out:

The procedures followed for all eight runs are described in detail in the complete paper.

During this operation, three CSBs were installed in accordance with ANP regulations. The first CSB inside the 7-in. liner created a barrier between two formations, and two CSBs were constructed at a height of 129 m to act as the main well barriers. The annulus cement was pressure-tested with positive results per the operator report delivered to ANP. Additionally, the CSBs inside the production tubing also were pressure-tested and approved.

The BHA in the first and second run was slim because of the risk of CT becoming stuck in the subsurface safety valve. This approach represents one type of mitigation offered to the operator for customized operation. The slim BHA overcame issues during the operations, such as sticking of CT at a reference point, passing through a restriction, and providing the same assurance for the operation regarding tension/compression capacity.

The next six runs were aided using downhole sensors to determine the exact location of the BHA to position the rotary jetting tool and the cement retainer to meet national regulations. During the entire run, internal/external CT pressure was monitored in real time by a field engineer; in case of abnormal pressure noted while setting the T-TIDS, a contingency plan could be applied on time in conjunction with operator-enabled onsite decision making.

After eight intervention runs in the well using CT, the package was customized per operator request in real-time mode in the field during the operation. The reliable execution process showed operability to P&A per regulations with adherence to all health, safety, and environment policies, one of the more important execution aspects within the industry. The success of this kind of dynamic intervention is the result of careful planning (DOS and simulation), daily BHA-tool maintenance, continuous monitoring of well conditions, and an excellent partnership with the operator in both the field and the office.

Overall, the results obtained with this intervention show that operational time was reduced because of efficient execution of the equipment and process, such as the real-time data-acquisition system, the depth-correlation (CCL) sensor, real-time interpretation of signals during the operation, and efficient T-TIDS setting procedures.
