Description

Overview

The Brent Bravo is a Shell operated platform laying approximately 116 miles off the coast of Lerwick, Shetland islands, in block211/29 of the UKCS.  It sits in 140 meters (459ft) of water.

With the Brent reservoir in decline, Shell stopped Brent Bravo production on 1st November 2014.  The Brent Bravo has now moved into its decommissioning phase, with the pug and abandonment of its wells to take place in due course.  

 

Background

The Brent field discovered in 1971, consists of four large platforms, with theBrent Bravo being the second southern most of the SSW-NNE layout.  As with all of Shells Northern North Sea (NNS) fields, the Brent field was named after a sea bird, in alphabetical order of discovery.  The Brent refers to the Brent Goose. Although the name Brent continued the sea bird theme, the name Brent also refers to the formations in which the reservoir sits: Broom, Rannoch, Etive, Ness and Tarbert.

 

Design

The Brent Bravo is a concrete gravity base structure design.  The Base alone weighings 300,000 tonnes and is capable of storing produce within its legs. The Bravo is equipped with drilling facilities and production facilities for both oil and gas. 

 

Production

All produce from the Brent Bravo is processed, before being exported to the Brent Charlie via a subsea pipeline before being sent on back to shore.  Oil produce currently runs into the Brent System Pipeline to Sullom Voe, Shetlands and gas produce into the FLAGS pipeline to St Fergus near Peter Head, Scotland.

With the Brent reservoir in decline, Shell stopped production of the Brent Bravo on 1st November 2014.  The Brent Bravo has now moved into its decommissioning phase, with the pug and abandonment of its wells to take place in due course.
