Projects are either already underway or in the pipeline in the subsea acquisition, installation, and decommissioning segments. Works remain focused within Western Europe though significant activity is also picking up in Australia and the Americas.
Shearwater GeoServices secures 4D OBS survey for Lundin Energy Norway
Shearwater GeoServices has been awarded a contract for a 4D ocean bottom seismic (OBS) survey at the Edvard Grieg field for Lundin Energy Norway.
SW Cook and SW Tasman will conduct the one-and-a-half-month project in the North Sea in the summer of 2022. This marks Shearwater’s return to the Edvard Grieg field to perform a third repeat 4D monitor survey.
UK-Germany interconnector cable works awarded to Prysmian Group
Italy’s the Prysmian Group has been awarded a contract worth around €1.2 billion (US$) by NeuConnect Britain and NeuConnect Deutschland for the turn-key design, manufacturing, installation, testing and commissioning of a 725-kilometre submarine interconnector that will directly link the German and UK electricity grids for the first time.
This 1,400MW submarine and land cable system will connect two of Europe’s largest energy markets.
The project will deliver the cable connection along a route that runs between the UK converter station located on the Isle of Grain in Kent, passing through UK, Dutch and German waters to the landing point in Lower Saxony in Germany to connect with the converter station near Wilhelmshaven.
Prysmian will provide the complete cable system to be operated at ±525kV HVDC utilising mass-impregnated (MI) paper insulated cables, and include fibre optic cables on the land and selected submarine sections, complemented with state of the art cable monitoring systems that will support the monitoring, maintenance and services to be provided during the warranty period.
Offshore installation activities will involve three of the group’s own cable laying vessels including Leonardo da Vinci, Cable Enterprise, and Ulisse. Commissioning of the project is scheduled in the second half of the decade.
McDermott completes subsea campaign for Bayu-Undan Gas Field in Timor Sea
McDermott International recently completed work under its first subsea, engineering, procurement, construction and installation (EPCI) contract with Santos NA for the Bayu-Undan Infill Well Phase 3C Project in the Timor Sea located approximately 500 kilometres off the northwest coast of Darwin, Australia, and 200 kilometres off the southeast coast of Timor-Leste.
The Bayu-Undan field is one of Timor-Leste’s largest gas fields. McDermott’s scope involved a tieback of a single in-field well to existing facilities, re-using existing flexible flowline, with a new umbilical and certain infrastructure.
Nexans wins US offshore wind export cables installation contract
Nexans has won a contract with Ørsted and Eversource to install and protect the export cable link for the Revolution Wind Farm off the US east coast.
The project will connect the wind farm to the onshore grid and help Connecticut and Rhode Island achieve ongoing commitments to develop offshore wind.
Located more than 24 kilometres south of the Rhode Island coast and 51 kilometres southeast of the Connecticut coast, the 704MW Revolution Wind Farm will address both states’ energy needs, delivering electricity to up to 350,000 homes in Connecticut and Rhode Island. Construction will start in 2023 and the site is scheduled to be fully operational in 2025.
Boskalis consortium bags Hollandse Kust West Beta export cabling project
Boskalis has been awarded the Hollandse Kust West Beta export cable contract by TenneT, in consortium with Orient Cables (NBO).
The contract scope comprises the installation of two 65-kilometre-long export cables that will connect the planned Hollandse Kust West Beta 700MW offshore wind farm to TenneT’s onshore grid in the Netherlands. Boskalis will also install a nine-kilometre-long 66kV interconnector cable between the Hollandse Kust West Alpha and Hollandse Kust West Beta offshore substations.
Boskalis will execute this contract in consortium with its partner NBO, which will design and supply the high-voltage cable system.
For this project Boskalis will deliver an integrated solution of in-house services including the removal of unexploded ordnance from the seabed, geotechnical and geophysical surveys, beach and seabed preparation works, and the laying and burial of the cables.
The Hollandse Kust West Beta offshore windfarm is expected to enter service in 2025.
DOF Subsea Australia to undertake retrieval works for Woodside Energy
DOF Subsea Australia has been awarded Woodside Energy’s Enfield XT Retrieval and Offshore Support Services contract.
The campaign execution will involve the recovery of 18 subsea trees, 18 flowbases and associated spool sections, one wellhead severance and recovery of up to 18 remporary guide Bases at the Enfield Field offshore Australia.
The contract includes project management, engineering, fabrication, and decommissioning services. It will be undertaken in the third and fourth quarters of 2022 using the construction support vessel (CSV) Skandi Hercules.
CGG tapped for 4D OBN imaging contract offshore Brazil
CGG has been awarded a two-part ocean bottom node (OBN) seismic imaging project by PXGEO over the Sapinhoá Shared Reservoir in the Santos Basin offshore Brazil.
The resulting data will bring improved geological insight to the asset operator, Petrobras, to assist with better management of oil recovery and production development.
The baseline 3D seismic survey acquired by the PXGEO Poseidon OBN crew, covering 575 square kilometres, is already being processed at CGG’s Rio de Janeiro subsurface imaging centre. CGG will process the 4D monitor survey after its planned acquisition, again by PXGEO, in 2023.
