Hornsea One Export Cable Installation Completed

The installation of export cables at the world's largest 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

NATO Uses IoT to Study the Oceans

, Arctic research becomes fundamental to guarantee safe and secure maritime traffic in the new routes around the North Pole. Thousands of SPOT Trace units are used for oceanography studies around the globe. These include the University of Oldenburg’s work monitoring plastic debris in the North Sea and Spain’s coastal authority, Salvamento Maritimo, using SPOT Trace to devise oil spill disaster recovery procedures. The National Institute of Oceanography and Experimental Geophysics and the “Istituto di Scienze Marine” of the Italian National Research Council use SPOT Trace

Vigdis Gets a Boost

Norway's Equinor said it has decided with its partners to invest some NOK 1.4 billion ($164.7 million) in a boosting station for the long-producing Vigdis field in the Norwegian North Sea.The new boosting station, expected to come online in the first quarter of 2021, is expected to raise production by almost 11 million barrels at the subsea field Vigdis, which has been producing oil through the Snorre field for more than 20 years.“This is an improved oil recovery project which includes a multiphase boosting station that will increase production from existing wells. This adds new oil barrels

Royal Navy Supports Successful Trial of New Micro-Robots

ecoSUB, has been successfully trialed in the North Sea off Orkney during a marine robot demonstrator mission coordinated by the National Oceanography Center (NOC).ecoSUB is a new type of Autonomous Underwater Vehicle (AUV) developed by Planet Ocean in partnership with the NOC. The vehicles are around 0.5 meters in length and weigh only 4 kg, and are therefore classified as 'micro-AUVs'. Despite their small size, they are capable of diving to 500 m (2500m for ecoSUB-m25) and have sufficient battery power to stay underwater for several hours.Two of the new ecoSUB-µ5-SVP vehicles were

Tidal Power for Seabed Oil and Gas Installations

for large underwater turbines engineered to harness power from tides and ocean currents to produce industrial-scale levels of electricity. At the smaller scale, tidal power can be just as useful and, indeed, can be much easier to deploy to meet commercial needs.A team of subsea engineers from the North Sea oil and gas industry saw one such potential opportunity and decided to set up their own company – EC-OG – to pursue it in 2013. The result of their endeavors is the Subsea Power Hub, a compact tidal- and ocean-current-based electricity generator, suitable for providing renewable power

Nexans Wins Hornsea 2 Contract

a contract to supply of over 200 kilometers of the high voltage alternating current (HVAC) subsea export cable system for the near shore section of  the world's largest offshore wind farm. The contract, from Danish developer Ørsted, is worth more than 150 million euros.Located in the North Sea, approximately 89 kilometers from the Yorkshire coast, the 1.4 GW Hornsea 2 is the sister project to Hornsea 1. Ørsted is now constructing the project, with completion set for 2022. Once Hornsea 2 begins operating, it will provide enough electricity to power more than 1.3 million homes.
