New installation works are in the pipeline in the UK North Sea, Mexico, and West Africa. Well intervention projects are meanwhile either underway or already completed in support of decommissioning activities in the Northern Hemisphere.
Allseas secures pipeline installation contract offshore Mexico
Allseas has been awarded a construction contract by TC Energy for a major offshore pipeline delivering natural gas to southeast Mexico.
Allseas' state-of-the-art pipelay vessels will install the pipeline, which will run approximately 700 kilometres south along the coast from Tuxpan connecting the ports of Coatzacoalcos and Dos Bocas.
The Southeast Gateway pipeline is the first major natural gas infrastructure project to emerge from a new strategic alliance between TC Energy and Mexico's state utility CFE.
Shell awards subsea EPCI work to TechnipFMC
TechnipFMC has been awarded an engineering, procurement, construction and installation (EPCI) contract by Shell for the Jackdaw development located in the UK North Sea.
The contract covers pipelay for a 30-kilometre tieback from the new Jackdaw platform to Shell's Shearwater platform, as well as an associated riser, spoolpieces, subsea structures, and umbilicals.
The tieback will use pipe-in-pipe technology, which is designed for high pressure, high temperature use.
C-Innovation, Grand Isle Shipyard wrap up P&A in support of platform decommissioning
C-Innovation (C-I) and Grand Isle Shipyard (GIS) have completed work on a plug and abandonment contract awarded by Helix Alliance Decom for the provision of pre-feed services for the decommissioning of three offshore platforms for a major deepwater client.
In phase one of the project, C-I provided remotely operated vehicle (ROV) services to deliver marine water inspection and integrated the data to provide live operations for the client operating fixed leg platforms in 165 to 200 feet (50 to 60 metres) of water. GIS' Aerobotics Drone Division meanwhile provided aerial inspection services.
The joint activities were executed to determine the current condition of the wells and the facility, enabling the timely decommissioning of the wells, platform, and jacket for each of the three platforms.
Expro completes subsea decommissioning project on Ireland's first indigenous gas wells
US-based energy services provider Expro has successfully completed the plug and abandonment (P&A) of Ireland's first indigenous gas wells.
Expro provided the delivery of integrated subsea and well test services over an eight-month period to intervene, plug, and abandon subsea wells from a mobile offshore drilling unit located in the Celtic Sea.
The subsea intervention scope utilized Expro's landing string assemblies system, supported by a complete backup system and direct hydraulic topside and subsea controls package.
Saipem bags €1 billion in new projects in Cote d'Ivoire
Saipem has been awarded two new contracts in Cote d'Ivoire worth approximately €1 billion (US$990 million) overall.
The contracts have been assigned by the Eni Cote d'Ivoire-Petroci consortium for the Baleine Phase One Project, for the development of the relative oil and gas field located offshore at a depth of 1,200 metres.
The first contract entails EPCI activities of subsea umbilicals, risers and flowlines (SURF) and of an onshore gas pipeline for the connection to the distribution grid. The start of operations is planned for the fourth quarter of 2022.
The second contract encompasses engineering, procurement, construction and commissioning activities regarding the refurbishment of the Firenze FPSO vessel, plus 10 years of operations and maintenance services of the vessel.
