Talisman Sinopec Montrose BLP Jacket

18-07-2014
 Another North Sea Oil and Gas Field under Extension

Sea and Land Project Consultants Limited provided detailed design and engineering services
to OGN for their EPC contract awarded by Talisman Sinopec in October 2012. The 5750 tonne
jacket and 2800 tonnes of piles form the foundations for the new bridge-linked platform on the
Montrose field within the Montrose Area Redevelopment (MAR) Project 210 km east of Aberdeen.

It left the OGN yard at Wallsend on Friday 13th June and arrived in the field on Sunday 15th June
aboard the 150m long Castoro XI barge. The pictures below show the jacket on its journey down
the River Tyne and its installation adjacent to the Montrose Platform.

The jacket was lifted, upended and set on the seabed that day by the Saipem-operated S7000 HLV.
Pile driving and pile grouting was successfully carried out over the next 5 days.

Standing in 90m water 130 miles east of Aberdeen, the jacket is secured to the seabed with 8 no.
2.43m diameter piles. It will eventually support a 14,000 tonne deck receiving gas via risers from the
Cayley and Shaw fields to be exploited as subsea developments. The jacket supports 12 no. gas risers,
4 no. j-tubes and 7 no. caissons.
