Offshore wind: One-stop Power Conversion

. The lingo is the same. Yaskawa’s The Switch is well-placed to hybridize vessels or help convert power from wind turbines. In the U.S., they’ve quietly built up a $500 million business in low-voltage and medium-voltage drives, with some sales of solar inverters on the side.Known in the North Sea for permanent magnet generators and frequency converters for wind turbines and marine power and propulsion, The Switch’s specialty is where the generator shaft meets the propeller shaft, with efficient drives for power outputs of from 0.5 kW to 11 MW.Their marine permanent magnet machines

Saab Seaeye eRobotics Campaign Wins UTC Award

Saab started investigating opportunities to work in the Norwegian market. Back then, the idea was ahead of its time.Now, thanks development projects with Italian operator Eni, as well as parallel developments in inductive underwater charging and data transmission technology, 4G connectivity across the North Sea and other basins, and the development of standardized docking stations, the market is catching up with the concept.  Earlier this year, during its eRobotics Spring Campaign, Saab Seaeye demonstrated the vehicle’s ability to dock in a safe and controlled manner at a remote sub-resident

technology is being promoted. In fact, the project started in 2010, with a prototype built in 2013/14. iDROP has also built a recovery system and performed an inshore test, for verifying the recovery system. A second pilot test, acquiring 3D seismic data, in deepwater, is planned for this year in the North Sea. Nine vehicles have been built and were due to go offshore for testing in the first half, with more planned to be built in the coming year.MUM’s the wordThyssenkrupp Marine Systems (MS), part of the German industrial conglomerate, is working on a different scale to both uSEA and uLARS.

Well-Safe Scores DNO Decom Project

Well-Safe Solutions announced Tuesday it has been awarded a contract to decommission up to 21 wells on the Schooner and Ketch fields in the UKCS, operated by DNO North Sea (ROGB) Limited, a wholly owned subsidiary of DNO ASA.The Schooner and Ketch fields, located in the UK Southern North Sea, ceased production in August 2018, with 20 platform wells and a single subsea well. The project will start immediately with a plan to commence offshore operations at the end of 2019. The campaign is expected to last approximately two years.Well-Safe said it will be responsible for the delivery of key aspects of

SUBSEA ENGINEERING: By-pass, superfast

When a troublesome pipeline beset with wax issues escalated into a blockage, new North Sea independent Chrysaor and Subsea 7 nimbly dealt with it, installing a 26km bypass pipeline in just eight months – despite facing multiple issues on the way.Chrysaor is a new operator on the UK Continental Shelf. Only about 18 months old, it’s got growth ambitions, after first acquiring a package of assets from Shell in 2017 in a $3.8 billion deal.But, acquiring existing producing assets can come with issues, including that they’re older, complex, interconnected and have been through multiple

Subsea Templates Installed on Nova Field

Two subsea templates have been installed for the Wintershall Dea operated Nova project offshore Norway, marking the first operational landmark for the new company formed from the May 1 merger of Wintershall and DEA.The Nova oil field, located in the Norwegian North Sea, 120 kilometers northwest of Bergen, is being developed with the two subsea templates tied back to the nearby Neptune-operated Gjøa platform in the North Sea. Gjøa will receive the well stream, and provide water injection and gas lift to the Nova field. A new module will be lifted onto Gjøa in 2020.Subsea 7’s
