Project Profile
Location: block K5, North Sea, 110 km northwest of Den Helder, Nederland
Production: 90 million cubic feet per day
Start-up year: September 2008
The K5F field is located in block K5 in the Dutch sector of the North Sea, approximately 110km northwest of Den Helder. It is operated by Total E&P Nederland BV of behalf of its partners Energie Beheer Nederland BV, Goal Petroleum (Netherlands) B, Dyas BV and Lundin Netherlands BV. The field began production in September 2008, initially at the rate of 45 Million Cubic Feet per Day (Mmscf/d) and ramping up to 90 Million Cubic Feet per Day (Mmscf/d) over the subsequent few months. The project includes a three-well combined template/manifold installed in 40 metres of water. The initial installation encompasses two template/manifold-mounted trees with the option for two more trees in the future, one of which would be a satellite tree. The jack-up drilling rig Ensco 72, used to drill these wells, was also used to install the two Christmas trees. The produced gas is exported through a 10kilometres long, 8 inches diameter subsea pipeline connected to the existing K6N satellite platform. The gas treatment facility on the K6N satellite platform has been modified in order to process the K5F gas. From there flow is exported via the K6 central complex for delivery to shore along the NoordGas Transport pipeline under contract to Gasunie for supply to the local gas network. Subsea 7 received a contract valued in excess of US$70m for engineering, procurement, construction and installation of the 8 inches diameter flowline and umbilical systems, together with the associated tie-in and pull-in operations. The contract also included the engineering, procurement, fabrication and installation of the subsea protective structure complete with the pipeline end manifold, integrated umbilical distribution equipment and associated activities. The massive 160 tonnes subsea cover was subcontracted to engineering contractor, Isleburn where it was built at the company\'s Nigg facility. The subsea cover was loaded onto a barge by a 500 tonnes crane at Nigg, for subsequent transfer to DSV Toisa Polaris. It was transported 400 miles to the K5F field in 48 hours.
