- rig capacity to operate: water depth 10.000 ft and drill up to 35.000 ft. drafts: - drilling draft 23.00 m - survival draft 19.00 m - transit draft 9.94 m - the platform is stranded about 17 nautical miles south breakwater from south american port. - the water depth in that area is around 22 meters. - the transit draft of the platform is of 9.94 meters. - an inspection was made with divers, and she's more or less of 40 cm in the drifted in sand seabed. - the 8 thrusters in the keel of the pontoon are damaged. - the 8 thruster rooms on the pontoons are flooded. - two of the four pump rooms are flooded. - all diesel tanks in the pontoons do not have diesel and the hull has no damages. there is no water penetration in the tanks. - on the pontoons access through the stairs on the columns is clear and available. - a company contractor has been hired to conduct risk assessment + flotation procedure + towing plan. owners will provide same upon inspection. - ballast tanks are free from flooding according to a previous class inspection. - the rig platform has enough buoyancy to be floated but when that happens it must have the tug (or tugs) ready/ on standby to take the semi-sub to the dry dock at designated shipyard location. - the platform is currently in black-out mode to avoid consuming of diesel. - on board there is no diesel to be able to start some main machineries which will enable to test how much ballast the platform has on board. - all security systems are out of service due to lack of electricity. horizon offshore services can provide quotations for the following scopes of work below for prospective buyers, as follows: - a) drilling rig recovery project, b) transportation project, 1): semi-submersible rig to be transported by heavy lift vessel. or c) transportation project 2): semi-submersible rig to be towed by tugs. - rig re-activation is in range of us$10 – us$14m it depends where rig will be reactivated. we can guide and provide quotations as per needed basis. - current market value cost of typical operational 2011, dp3 class harsh environment semisubmersible drilling rig is minimum in the range of high thirties. should you have any questions please do not hesitate to contact at your convenience. direct buyers and their appointed representatives must sign ndnca in order to receive all technical & commercial information from reputable vessel owners.
