Mooring technology set for installation at world’s first floating tidal power array

The first phase consists of a 420-kilowatt PLAT-I tidal energy platform, and Seasystems AS has been commissioned to supply adjustable mooring tensioners. Lying on the seabed, these are attached to the anchors that hold the power station in place in the strong tidal current – connecting the anchor chains with the anchors. 

Seasystems has joined forces with Swift Anchors, a division of Sustainable Marine, in developing a unique hybrid mooring connector and anchor solution, specifically targeting wave, tidal, floating wind, floating solar, ocean thermal energy conversion, deep water aquaculture and other challenging anchor applications. This new solution, applied to the Pempa’q project, involves the integration of Seasystems’ adjustable mooring tensioners with Swift Anchors’ broad anchor product portfolio including groutless rock Anchors, screw anchors, drag embedment anchors and grouted self-drilling piles.

“We are pleased with our alliance with Seasystems, which has strong reputation for innovation in the maritime market, forming part of Scana ASA listed on the Oslo Stock Exchange. The integrated tensioning system significantly eases the installation process for any floating platform and provides increased flexibility in the mooring system design,” commented, Swift Anchors managing director, David Ainsworth.

The Pempa’q In-stream Tidal Energy Project offers several benefits, both locally and globally. First and foremost, the tidal power plant will provide predictable, renewable, and clean energy. It will be able to power around 3,000 homes and will reduce greenhouse gas emissions by 17,000 tonnes of CO2 annually. Globally, this means lower greenhouse gas emissions and less harmful effects on the climate and the environment. Locally, it means reduced dependency on coal as an energy source, and fewer harmful effects on the local environment.
