Field Burghley
Area Central North Sea
Operator Talisman
Development concept Subsea
Transport concept 10.4km pipeline to Balmoral
Start-up Q4 2010
Comments: Approved Oct 2009. Talisman is developing Burghley as a subsea tieback to the
Balmoral floater, which is operated by Premier. It will be produced through a single well, a new
sidetrack in appraisal well 16/22-9 which was drilled and completed by semisub Ocean
Princess in Sept-Nov 2009. The well will be tied back to Balmoral by a 10in production pipeline
with a 4in lift-gas line piggybacked on it; Technip is due to lay these lines in May. FMC
supplied the subsea tree, RRC the subsea controls and Duco the umbilical.
Field *Laggan/Tormore
Area West of Shetland
Operator Total
Development concept Subsea to shore
Transport concept 2 x 140km pipelines to Sullom Voe, 15km inter-field pipeline,
224km pipeline from Sullom Voe to Frigg UK line
Start-up Mid 2014
Comments: Approved Mar 2010. The development of the Laggan and Tormore
gas/condensate fields west of the Shetlands will benefit from a tax allowance worth up to
£160m per field for deepwater WoS developments. Start-up is scheduled for 2014. Basic
engineering was awarded to a joint venture between ODE and Doris. FMC will supply subsea
equipment and Corus line-pipe, a volume of 150,000t. Other awards are expected shortly.
Subsea equipment will be installed in 2011 to allow drilling to start in 2012 – there will be up to
five wells on Laggan and three on Tormore. Recoverable reserves in the two fields are
estimated at 1.5 tcf. Gas and condensate will be sent to the terminal via two 140km multiphase
pipelines. From there gas will be transported to the mainland via the East of Shetland pipeline
– a 225km, 30in line linking into the Frigg UK pipeline at the MCP-01 location. The gas line
from Laggan will have 665 MMcf/d capacity, enabling it to act as a hub for third-party gas: 100
MMcf/d from Chevron’s Rosebank/Lochnagar field and 65 MMcf/d from BP’s Clair North, in
addition to 500 MMcf/d from Laggan/Tormore. Total plans to install subsea gas compression
facilities within five years of start-up. In around 600m of waters, Laggan and Tormore will be
the deepest developments yet undertaken in the UK sector. Total has also become operator of
the Tobermory gas discovery some 130 km to the north, with a view to bringing it on stream
through the Laggan infrastructure in 2016.
