Offshore wind: One-stop Power Conversion

of three 3,800 kW propulsor drives; three 2,700 kW tunnel thrusters and, in is understood, a DC Hub for each vessel.  Future wind-service vessels look set to face an increasing amount of environmental scrutiny and can expect to one day have to operate as hybrids. New wind players are often national grid managers involved in wind precisely for the green footprint. Even established players with roots in oil, like Equinor, have been known to insist on greener power from their marine suppliers.“Our drives match turbine installation vessels very well,” Parpala said, explaining that specialized

New Offshore Wind Foundation Tested

into deep waters where traditional construction methods of hammering monopiles into the seabed are becoming more and more expensive, its developers say.HR Wallingford notes that as of March 2019, the UK had almost 2,000 offshore wind turbines with over 7.8 GW of power generation capacity, which the National Grid “Future Energy Scenarios” predict could rise to almost 30 GW by 2030.The company says new foundation solutions are needed as construction accelerates and shifts to deeper water, and energy markets become increasingly competitive – since comparison sites make it easier to switch

Hornsea One Export Cable Installation Completed

offshore wind farm, Hornsea One in the North Sea off the coast of England, has been completed several months ahead of schedule, Danish operator Ørsted announced Tuesday.With offshore export cables totaling 467km, plus an onshore cable route of 38km connecting each of the three strings to the national grid, it is the longest AC offshore wind export cable system ever to have been installed. The cables were manufactured by NKT at their facilities in Cologne and Karlskrona.Tideway BV installed the three landfall cable sections using sub-Contractor VBMS and their vessel Ndurance.

Beatrice Offshore Wind Farm Produces First Power

Beatrice wind farm off the Caithness coast in Scotland has generated power for the first time, operator SSE said on Thursday.Following installation of the first 7-megawatt (MW) turbine, the wind farm exported power to the National Grid, the firm added.The 2.6 billion pound ($3.4 billion) wind farm will be completed in spring 2019. It will have capacity of nearly 600 MW and be capable of supplying around 450,000 homes with power.Beatrice Offshore Windfarm Ltd is a joint venture between SSE, Copenhagen Infrastructure Partners and Red Rock Power Ltd.($1 = 0.7693 pounds)(Reporting by Nina Chestney;

North Sea Link Trenching Contract Awarded

Offshore Limited said it has been awarded a contract to provide offshore cable trenching services on the North Sea Link Interconnector linking the U.K. and Norway.   The project, which will establish a first direct connection between the two countries energy systems, is a joint venture between National Grid and Statnett SF, the Norwegian transmission system operator. The 1,400MW subsea HVDC system when complete will be the world’s longest submarine interconnector.   The multimillion dollar subcontract was awarded by Prysmian PowerLink S.r.l, who are manufacturing and installing the
