Offshore Project News Roundup | September 20 – Investigations in Europe and Australia, French and Taiwanese wind farm installations and more

Construction work is progressing on wind farm projects in Taiwan and France while studies are underway off Australia and Italy. Subsea installation work will be undertaken in Brazil. Finally, a dismantling project will cover four large platforms in the British North Sea.

Allseas secures the dismantling works of TAQA

Allseas has been awarded a dismantling contract by TAQA UK for the removal and disposal of
several Northern North Sea (NNS) facilities.

The Engineering, Preparation, Removal and Disposal (EPRD) contract includes TAQA’s Eider Alpha, Tern
Alpha, North Cormorant and Cormorant Alpha platforms. The combined weight of the topsides and jackets to be removed is approximately 114,000 tonnes.

Allseas task is to remove four platform tops, three steel support casings and transport them to a suitable location
site installation on land for dismantling, with the aim of reusing or recycling 95% or more of the materials.

The rigs are located close to each other, approximately 100 kilometers northeast of Shetland, in waters at depths ranging from 150 to 167 metres. All structures will be lifted and transported ashore as individual units using Allseas heavy lift vessel Pioneering spirit.

Platform deletions are planned after 2025.

Fugro will carry out site studies for the future Italian offshore wind farm

Renexia, part of Italy’s Toto Holding, has awarded Fugro a study contract for the Med Wind floating wind farm in the Strait of Sicily.

Fugro will provide Renexia with detailed geophysical and marine environmental studies, deploying state-of-the-art equipment and specialized personnel to acquire comprehensive geographic data at the location of the proposed wind farm and along the two proposed export cable corridors. The acquisition will take place at depths between 300 and 900 meters.

The results of the analysis will be used to advise on geohazard mitigation and identify a safe route for the installation of the two export cables.

When completed, Med Wind will be one of the largest renewable energy projects in the Mediterranean, with 190 floating turbines for a total installed capacity of 2.8 GW.

Shearwater GeoServices and WesternGeco Sign Seismic Acquisition Agreement

Shearwater GeoServices has entered into a multi-year agreement to purchase geophysical data acquisition services from WesternGeco and award a study in Australia under the new agreement.

The agreement provides access to Shearwater’s full suite of acquisition technologies and its global fleet of seismic vessels.

The survey assignment, in the Bonaparte Basin off Australia, will last approximately two and a half months and will be conducted by the acquisition vessel geo coral. The survey is subject to regulatory approvals in Australia.

The objective of the proposed seismic survey is to provide an enhanced subsurface image of the eastern flank of the Vulcan and Londonderry High sub-basin. The new data will provide a better understanding of the subsurface, which to date has been limited due to the inability of old surveys to resolve shallow carbonate intervals and complex faulting.

TechnipFMC Wins TotalEnergies EPCI Subsea Contract Offshore Brazil

TechnipFMC has been awarded an engineering, procurement, construction and installation (EPCI) contract with TotalEnergies.

The work will be undertaken in TotalEnergies’ Lapa North East field in the pre-salt Santos Basin offshore Brazil.

TechnipFMC will reconfigure and install the umbilicals and flex lines in a new configuration that will further secure field production.

Jan De Nul completes the installation of the foundations of a wind farm in Taiwan and the installation of a turbine offshore France

Jan De Nul Group has successfully completed the installation of the 47 jacket foundations and 188 pin piles, as well as the four export cables and the 47 inter-grid cables of the Formosa 2 offshore wind farm in Taiwan.

In the coming weeks, a vessel from local partner Dong Fang Offshore (DFO) will continue to provide easy access on foot to work for crews finalizing cable terminations, allowing the entire wind farm to be energized. Jan De Nul will complete the burial and stabilization of the remaining cables during the month of September 2022.

Jan De Nul has also successfully completed the transport and installation of 80 sets of 6 MW wind turbines on the Saint-Nazaire wind farm project in the Bay of Biscay 12 kilometers off the coast of France. The installation took five months and was completed in early September.

The Saint-Nazaire offshore wind farm will have a total capacity of 480 MW when it becomes operational at the end of 2022.
