OneSubsea Awarded Chevron Master Agreement

Chevron has awarded OneSubsea a 20-year subsea equipment and services master contract for development projects in the Gulf of Mexico, the subsea supplier’s parent company Schlumberger announced on Tuesday.Combining this master contract with a preapproved catalog of standardized subsea equipment will enable the US supermajor to decrease operating costs in its subsea projects, Schlumberger said.The provision of a OneSubsea custom catalog of equipment will also include innovative technologies that meet Chevron’s project requirements, including high-temperature projects or high-pressure

History: First MODU to Use Subsea Well Control

In 1955, the Western Explorer, owned by Chevron, is introduced in the Santa Barbara Channel as the first floating drilling MODU to use subsea well control. The unit, built by the CUSS group (Continental, Union, Shell, and Superior Oil (now Global Santa Fe)), measured 260 feet and had a 48-foot beam. It was retired in 1972. Marine Technology Reporter has been commissioned to publish the Official “Oceanology International 50th Anniversary Edition.” For information on advertising in this edition, contact Rob Howard @ howard@marinelink.com or Mike Kozlowski @ kozlowski@marinelink.com.

come with complete records – including exactly where and what diameter pipelines are.The Lomond platform (initially operated by Amoco, BP, BG Group and then Shell) sits 145m east of Aberdeen in 83.8m water depth and started producing in 1993. Gas condensate from the Erskine facility, operated by Chevron, is exported to the Lomond platform and then 57.8km on to the Everest platform for onward export via the CATS system into the Forties Pipeline System to shore.When Chrysaor took on Lomond as part of its acquisition of (ex-BG Group) assets from Shell in 2017, it knew there was a history of blockages

Wood Wins Jansz-lo Subsea Compression FEED

Wood announced on Wednesday that it has secured a contract with Chevron Australia to provide subsea integration and flow assurance front-end engineering design (FEED) services for the Jansz-lo compression project offshore Western Australia.The project – the first outside of Norway to use subsea compression technology – will maintain gas supply to the existing onshore Gorgon liquefied natural gas (LNG) facility.Wood said it will lead as system integrator of the technology, providing independent flow assurance, subsea design and construction engineering support during the FEED.

Chevron to Use Subsea Compression at Jansz-Io

Aker Solutions announced Tuesday it has been awarded a master contract to support the delivery of a subsea compression system for the Chevron Australia-operated Jansz-Io field offshore Australia, marking the first time the technology will be used outside of Norway.Compression helps to maintain plateau gas production rates as reservoir pressure drops over time, but such compressors have typically been installed on platforms over sea level. Placing this equipment on the seabed and near the wellheads improves recovery rates and reduces capital and operating costs, Aker Solutions said.The first

New Subsea Pipeline Decommissioning Tool

Hydraulic subsea tools specialist Webtool said it is developing a Fast Intervention Tool for subsea pipeline decommissioning in conjunction with Chevron Energy Technology Company. The tool will crimp, seal, and cut the pipe reducing the potential for contamination of the marine environment, potentially removing the requirement for a containment dome during pipeline cutting, and minimizing diver intervention.The Fast Intervention Tool (FIT) is a modular design which combines lifting, crimping, injection and cutting in a single lifting and deployment frame which also contains the hydraulic control system.
