The operations were governed by an agreement between the British government and the Norwegian government, the Frigg Treaty. The agreement may subordinate part or all of the agreement to the agreement of the contracting parties. The development and operation of fields beyond UKCS borders or fields entirely located on either continental shelf, which require the construction of new pipeline or well infrastructure and cross-border controls, require formal agreement between the States concerned. Licensees are advised to obtain specific guidance from the OPC at an early stage for any development proposals that may have cross-border effects during the screening phase. The approval period for cross-border domains depends on the level of correspondence required between the states concerned. Below is a list of relevant treaties and agreements. This list may not cover all contracts and agreements and it is best to confirm contact with the corresponding OGA area team. In May, the company invited seven contractors to propose concepts to remove recall platforms using single elevator technology, including an option for disposal operations. Offers are coming back to the company this summer and ConocoPhillips intends to award a contract towards the end of the year, said Kari Amundsen, director of the Ekofisk I Cessation Project.
The decree could have been promulgated earlier, but it was partly frozen because both governments wanted to give their consent at the same time and, on the other hand, to bring into force amendments to the Norwegian law on the reimbursement of dismantling costs. Under the new rules, all costs are treated as operating expenses, making life easier, Bé said. The plan costs NKr 3.48 billion, or $266.3 million, with about 50% due in each country. In addition, the cost of clogging and abandoning wells on DP2 and decommissioning Topside equipment is estimated at NKr 1 billion, or $80 million. Last year, ConocoPhillips said it wanted to contract two. However, on the basis of further evaluation, the current strategy is to award a contract for the extent of the overall removal of the two booster platforms, Amundsen said. Bridge from the Frigg field in front of the Norwegian Petroleum Museum in Stavanger Until this autumn, Total E-P Exploration Norge AS (Total Norge) is counting on all the necessary approvals for the Frigg exit plan and is preparing the first steps of its implementation. The acceptance process has been made complex because the fields are overhanging Norwegian and British waters, so the company must obtain the approval of both governments. Production is expected to be completed in the spring of 2004, although production can be maintained until the middle of the year.
The hook-down is done in parallel with the front engineering design work for the moving contracts. With this approach, Total provides for good security control, which it seems to recognize as one of the most important themes. For the same reason, some existing platform staff are being retained for this phase. The 70 m high tank cells are filled with water, with a sedimentary layer on the ground in the different cells between 10 cm and 1 m thick. A layer of oil and wax a few centimetres thick floats on the water. Total, which has participated in joint industrial projects to develop new methods for the rem-oval platform and topside structure cutting, has set a deadline until 2012 for the completion of the relocation project. As a partner of Ekofisk, the company will have access to the experience gained through the use of the new unique lifting technology for the removal of the two Ekofisk Booster platforms. In this way, new individual elevator contractors will be able to qualify for pre-qualification.
One of the newcomers is Technip-Coflexip, which has carried out a series of studies on the use of its new jackup-rig concept to remove Frigg structures.
