SUT serves up subsea sundowner

THE Society for Underwater Technologys Australasian branch is holding a session, Subsea projects ...

Presentations will cover: the Mutineer-Exeter project; the world’s northernmost LNG project, the Statoil Snohvit development; and the Girrasol subsea system in deepwater Angola, west Africa.

The session will be held in the hotel’s John De Baun Room. The bar opens at 5.30pm, with presentations beginning at 6pm, and canapes and drinks served at 7pm.

Registration fees are A$10 for SUT members and A$30 for non-members. Student members and new members can attend free. The Melbourne Hotel is on the corner of Hay St and Milligan St, Perth.

Ghosh Consultants principal Dilip Ghosh will discuss “Mutineer-Exeter: an artificial lift showcase project”.

Mutineer-Exeter has advanced Australian subsea technology to global prominence with the use of downhole electrical submersible pumps (ESPs) and multiphase booster pumps integrated with an extensive subsea field development. Previously restricted to dry-tree developments, the subsea ESPs require high-voltage power reticulation and complex control systems.

Former ABB Offshore Systems senior project manager, Mathias Owe, now with Vetco Gray Australia, will discuss Statoil Snohvit, an LNG development in the Barents Sea off Norway’s north coast that uses remote control and instrumentation for subsea wells over distances in excess of 200km.

Owe will discuss the control and instrumentation provisions for Statoil’s Snohvit project and the use of fibre-optic communications to provide bandwidth and high availability over these distances. Back-up command and control via a power line signalling system and the use of back-up intervention controls on a temporary or emergency basis will also be described.

FMC Technologies’ Brian Woodman will discuss the subsea system in the Girrasol field, 210km off the Angolan coast in water about 1400m deep. The presentation will give an overview of the subsea architecture, wellhead completion equipment, control system, manifolds and diverless connections systems.
