Offshore Operations and Management
Operations at Paimpol-Bréhat tidal test site
In October 2022, Inyanga Maritime was awarded a contract to perform a cable upgrade operation at the Paimpol-Bréhat tidal test site. This was the first offshore operation in French waters for the ‘Inyanga Entsha’, a dynamically-positioned, multi-purpose vessel dedicated to the marine energy sector.
Connector installation for SEM-REV
In April 2023, Inyanga completed the installation of the connectors on the cables for SEM-REV, the first European site for multi-technology offshore testing that is connected to the grid, and prepared them for installation offshore. These new submarine cables aim to increase SEM-REV’s connection and grid injection capacity to up to 10 MW. The static and dynamic cables were supplied by Prysmian Group and the connectors by ETA.
Installation for offshore hydrogen production
In June 2023, Inyanga installed a dynamic cable for the Lhyfe offshore hydrogen production demonstrator, located on the SEM-REV test site. The dynamic cable is connected on one side to one of the static cable tails and on the other side to the floating Wavegem platform. Several jewelleries had to be installed on the cable. The cable crosses over two other cables and has been protected there by Uraduct-type protections and rock bags.
Installation for Eolink
In July 2023, Inyanga installed the mooring lines for an innovative floating wind project run by Eolink. Eolink is a French company developing an innovative floating wind technology with a single point mooring system and aims at installing a 5 MW turbine at the SEM-REV test site in 2024. The operation was performed with difficult weather conditions and challenging soil conditions, in a very constrained area. The operation was performed using the AHTS Pacific Dispatch and included the use of a reaction anchor and a stevtensioner.
Upgrade at SEM-REV
In July 2023, Inyanga Tech installed new cables on the submarine hub of the SEM-REV renewable energy test site. The aim was to upgrade the site and pave the way for hosting future prototypes. This offshore work programme is the conclusion of several years of joint effort. These operations were carried out by teams from SEM-REV and Inyanga Tech, the Inyanga Marine Energy Group’s French subsidiary.
Inyanga installs anchorage system at SEM-REV
In summer 2023, Inyanga completed installation of the Floating Offshore Wind Turbine anchorage system at the SEM-REV offshore test site, operated by OPEN-C Foundation, off Le Croisic in Western France, as part of the 5MW France-Atlantique project. With the anchorage system now in place to secure the floating unit, EOLINK aims to complete the final phase in the France-Atlantique project by installing a demonstration 5MW FOWT in 2024.
Tidal Energy Projects
In Autumn 2023, HydroWing were awarded a contract for a 10MW tidal stream [BW1] energy project in Wales, through the UK government's latest Contracts for Difference round. The project will be located at the Morlais tidal energy site in Anglesey, which is managed by the social enterprise Menter Môn. The Morlais site is the UK's largest consented tidal energy scheme.

In September 2022, UK-based tidal energy developer HydroWing signed a Memorandum of Understanding with state-owned company Indonesia Power to support and develop tidal energy projects in Indonesia. This will accelerate tidal energy development in Indonesia through site identification, resource assessment and front-end engineering.
