Chevron To Relaunch Tender Process for Rosebank

March 29, 2018

Chevron to relaunch tender process for Rosebank production vessel later this year as it advances through feed phase and progresses towards FID.

Discovered fourteen years ago 80 miles north-west of the UK Shetland Islands on the Atlantic Margin, lies Chevron’s undeveloped Rosebank oil and gas field, in which it holds a majority stake. Rosebank is deemed to be one of the most promising, undeveloped areas of the UK North Sea, in waters over a kilometre deep with potentially recoverable resources estimated to be between 240-300mil barrels of oil. If the US oil major successfully develops it, the field will be one of the biggest new developments in the UK North Sea.

Chevron currently own the Rosebank field, located in blocks 213/26 and 213/27, with an additional 40% interest, partnered with Statoil’s ownership of 30%, OMV’s of 20% and Dong’s 10%. July 2007 saw the successful appraisal of the field with Chevron’s hefty investment of $327mil and the drilling of well 205/1-1, and the recorded rate of flow was 6K bpd. The US supermajor recently announced they’d be investing a further $6-8bn in the two North Sea blocks situated in 1110m of water depth, close to the Faroese waters. Chevron’s original plans for Rosebank several years ago indicated it might create up to 300 additional jobs in Aberdeen

All this sounds promising for the operator company; however, the Rosebank project has been anything but smooth-running. With initial costs for the project estimated at a whopping $10bn in 2013, Chevron were forced to cancel their original contract with the South Korean shipbuilder company responsible for the FPSO. Later in the same year, Chevron officially deferred the project, requiring more time to improve its economics for the FPSO project intended to transport natural gas via pipeline.

In December, the company sent a termination notice to HHI (Hyundai Heavy Industries) for their order of the vessel, valued at just under $2bn. Its measurements were 29m x 57m x 30m and its design would have enabled it to endure the harshest of conditions. Furthermore, the FPSO was to be able to produce 100,000 bbl (billion barrels of liquid) and 190 MMcf/d of natural gas, with a storage capacity of 1.05 MMbo (million barrels of oil). HHI had already placed orders for production systems, an almost 100,000-tonne turret and a newbuild semisubmersible rig designed for development drilling, all of which had to be cancelled upon the project’s deferral due to the higher than anticipated costs owed to the water depth and hostile weather conditions.

However – hope is not lost for Rosebank. After cancelling their initial order for the FPSO, Chevron has recently confirmed that they will soon be relaunching the tender process and issuing new invitations to bid for the production vessel project later in the year. A Chevron spokesperson has already made a statement confirming that the project is currently in FEED phase with a design capacity of 100,000 barrels of oil and 80 MMcf/d of natural gas. When the question of FID arose, the spokeswoman claimed it is too early to offer a date as FEED is still yet to be completed, however Rosebank is still progressing as optimization work continues and Chevron are fully committed to this venture.

With the market developing significantly in the North Sea, candidates with FPSO and North Sea experience will be highly sought after to fill positions on this project, so please ensure that you send us your up-to-date CV to be considered!
