Skandi Navica confirmed for TalismanContracts, Tenders and Rates // June 25, 2004
The contract is for the development of the Tartan North Terrace "B" discovery as a subsea tie-back to the Tartan-A platform. One 6in rigid production pipeline and a 3in gas lift pipeline of 3.4km are to be installed and a new umbilical will provide electrical control and signal functions.
Tie-in at Tartan-A will be by way of 280m flexible production and gas lift jumpers with the tie-in at the tree via conventional rigid tie-in spools. At each end of the pipelines a tee and valve assembly is to be installed to facilitate future tie-ins. Additionally, assistance will be provided for the commissioning of the Well B tree controls systems with the new lines and umbilical system being pre-commissioned.
The work is being carried out by Subsea 7's pipelay vessel Skandi Navica, a diving support vessel as well as a trenching spread.
Subsea 7 has also been awarded a contract for replacement pipeline works on Talisman's Beatrice field. This work involves laying and trenching 1.5km of 6in pipeline.
The combined value for both contracts is in excess of US$10 million.
