Subsequently, the Rambiz lifted the bottom end, while a tug controlled the heading of the top of the spar coming down. A subsea lifting frame was installed at the bottom end of the spar. First the Rambiz lifted the helideck and topside from the spar. Eager.one positively assessed Scaldis’ plan which included our previous recommendations. Decommissioning of the Draugen FLPĪfter a contractor switch, Scaldis got the job with its HLV Rambiz. One of the ideas was a lifting frame, like a bucket, at the bottom end of the spar. We produced a full report with notes, comments and possible solutions to Shell. The field has been developed with a concrete fixed facility and integrated topside, and has both platform and subsea wells. Draugen was discovered in 1984, and the plan for development and production (PDO) was approved in 1988. The contractor’s plan did not take into account the structural integrity, how the spar was installed originally and the damage in the spar-middle. TRONDHEIM, Norway OKEA is working on a tieback of the Hasselmus gas field in the Norwegian Sea to its Draugen platform complex. Draugen is a field in the southern part of the Norwegian Sea. After this research we concluded that reverse installation wasn’t possible as the plan suggested.”Įager.one handed over a comprehensive report advising against the proposed plan. By climbing the spar I noticed damage, which we certainly had to include in our calculations. We have extensively studied the Draugen FLPs’ history: how the FLP was filled with ballast water and iron ore and how the FLP was constructed. The fjords are incredibly deep and the spar looked like a little bobber in the big fjord. Hubert: “It was a great decommissioning project to support. Generally speaking, a shift runs from 07.00 to 19.00, and from 19.00 to 07.00. They do 12-hour shifts, either day or night, and their working hours over a year compare with those of an industrial worker on land. Remaining reserves are roughly 20 million barrels of oil and 9 BCM natural gas.For a total insight our senior project engineer Hubert Boter visited the FLP. Draugen employees work offshore for two weeks, followed by four weeks off on land. At the same time, the tethering blocks for the Snorre A concrete tension-leg platform were under construction on two barges moored alongside the dry dock. The contract for upgrading Njord A, (worth NOK 5 billion) was awarded to Kværner. had direct consequences for safety thinking related to Draugen.

Sikkerhet offshore fram til 1990, engelsk, With the priority given to efficiency and productivity, safety measures were regarded to some extent as unnecessary costs. Between 20, the field is being shut down to allow for upgrades to the facilities. Ownership of the field is divided between Wintershall Dea Norge AS (50%), Equinor Energy AS (27.5%) and Neptune Energy Norge AS (22.5%). Operation facilities at the field consist of Njord A, a floating steel platform unit, containing drilling and processing facilities (along with living quarters), and Njord Bravo, a storage vessel. Although the field was discovered in 1986, production did not begin until 1997. The field lies around 130 kilometres (81 mi) northwest of Kristiansund municipality, Norway. The theory of power maximization suggests that the optimal pressure ratio of the air compressor is 2.80, leading to an exhaust gas temperature of 145.5 ☌. The Njord oil field ( Njord – petroleumsfelt) is an oil field 30 kilometres (19 mi) west of the Draugen field, in the Norwegian Sea. An air bottoming cycle is design to recover the waste heat from the SGT-500 gas turbine installed on the Draugen platform, Norway, in the North Sea. Wintershall Dea Norge AS (50%), Equinor Energy AS (27.5%) and Neptune Energy Norge AS (22.5%) 64☁6′15″N 7☁2′02″E / 64.2708°N 7.2006☎ / 64.2708 7.2006 The Draugen platform has produced oil and gas with an overall value of roughly NOK 250 billion over the 25 years since it came on stream. ![]()
