NORTH SYDNEY, Australia CNOOC Petroleum Europe Ltd. has awarded Worley a two-year contract extension to provide engineering, procurement, and construction (EPC) services to three operated assets in the North Sea.

The contract involves more than 200 personnel, including the onshore and offshore teams, that provide EPC services for the Golden Eagle, Scott, and Buzzard platforms from front-end engineering and design (FEED) through to commissioning.

Worley completed construction of the greenfield module for the Buzzard Phase II development in early 2020. Weighing 474 metric tons (522 tons), it will be installed on the southwest corner of the Buzzard ‘P’ platform.

The module was designed and engineered by the company’s project office in Aberdeen, UK, and subsequently constructed by Rosenberg Worley at its fabrication facility in Stavanger (Hundvåg), Norway.

Dynamic commissioning of the completed module is ongoing. It is expected to be installed in the Buzzard field in the summer 2021.

In addition, Hibiscus Petroleum Berhad subsidiary Anasuria Hibiscus UK Ltd. (AHYUK) has contracted the company to provide FEED services.

The contract is Worley’s first with AHUK in the North Sea and will see the delivery of a multiple-discipline FEED for the upgrade and repurposing of an existing FPSO to support Phase 1 of its Marigold development.

The Marigold development includes two oil discoveries, Marigold and the Sunflower, which lie in the P198 license covering blocks 15/13a and 15/13b of the UKCS, about 215 km (134 mi) northeast of Aberdeen.

Phase 1 of AHUK’s development consists of three subsea production wells followed by a further drilling stage, Phase 2, in late 2022.

Worley began work in January and will continue to support the project throughout 2021. The contract is being led by the company’s Aberdeen operations with support from its Global Integrated Delivery team in Hyderabad, India.

The multi-discipline FEED will define the modifications recommended to accommodate the process fluids.

Its suite of digital tools, which digitize pre-FEED deliverables, are expected to reduce risk, expedite schedule, and lower costs.
