West of Shetland Developments

6 November 2013 Aberdeen Evening Meeting

Chairman Richard Ficken, Total E&P Ltd.



SUT+ Pre-Talk

Richard Ficken, Subsea and Pipelines Manager, Total E&P Ltd
SUT+ Pre-talks are targeted at developing professionals and newcomers to industry, with the aim of providing attendees with additional background subject knowledge to enhance the main SUT presentations which follow.

Achieving the greatest value from decommissioned flexible pipes
Paul Benstead, Pipeline Integrity Manager, BP North Sea Operations

TEPUK Laggan-Tormore Project – Flow Assurance and Subsea Architecture
Simon Hare, Operations Manager, Laggan-Tormmore Porject, Total E&P UK
Total E&P UK is currently developing the Laggan and Tormore gas-condensate fields located in 600m of water 125km to the west of the Shetland islands, with first gas planned for 2014. The fields are developed through two 6-slot integrated template manifolds, tied back via two 143km x 18” flow lines to the new-build Shetland Gas Plant being constructed next to the Sullom Voe Terminal on Shetland. This presentation will give an overview of the key flow assurance challenges and the subsea hardware, and will highlight some of the new equipment and systems deployed to improve the operability of the field.

Rosebank Subsea Challenges
Peter Blake, Subsea Systems Manager, Chevron Energy Technology Company
The Chevron-operated Rosebank project is located approximately 80 miles (130 kilometres) north -west of the Shetland Islands in blocks 213/26 and 213/2. It lies in water depths of approximately 3,600 feet (1,100 meters) and will be Chevron’s first deep water development in the UK. The field, discovered in 2004, is estimated to contain total potentially recoverable oil-equivalent resources of 240 million barrels. The planned development will include a Floating Production, Storage and Offloading (FPSO) vessel tied to subsea production and water injection wells and a gas export pipeline. Any West of Shetland deepwater development is susceptible to harsh weather, rough sea states and phenomenal offshore environmental forces. In the case of Rosebank this is exacerbated by the large distance offshore and the deepwater nature of the project. This presentation will provide an overview of the project and discuss some of the subsea
engineering technical challenges involved with developing a field in this environment.
