The contract also includes options for offshore hook-up of the process and living quarter platforms for Johan Sverdrup. Large Self-Installing Platforms - TPG 500 Technip has designed the 3 largest self-installing TPG 500 production jack-up platforms in the world with topsides weights of 17,000 elements Harding30,000 tonnes Elgin and 20,000 tonnes Shah Deniz. Construction and pre-commissioning is typically performed as much as possible onshore. The contract has an estimated value for Kvaerner of approximately NOK 450 million. Specialist floating hotel vessels known as are used to accommodate workers during the xi and hook-up phases. Once on location, the Gangway Landing and Access Tower structures were installed, secured and connected rapidly and without hitch. The company added that it has been supporting Semco Maritime with the setup of a team of hook-up specialists to prepare the installation work in Singapore and will be la together a UK based team to have everything planned when the platforms arrive in the North Sea. In one recent instance where a steel jacket supported process, drilling and accommodation facilities, the offshore work accounted for 25 % of the total project cost and 25% of the total project duration. Glad of these types of vessel are constructed in marine yards but are often involved during the construction phase to pre-drill some production wells. TPG 500 Monopod Based on the proven TPG 500 concept, the monopod platform is self- installing in a single marine operation using 3 hook up offshore platform and suitable for topsides of up to 12,000 tonnes. ABS class approvals for all vessel and new accommodation modifications were required before sail away.
Oil platform Offshore construction is the installation of structures and facilities in a marine environment, usually for the production and transmission of electricity, oil, gas and other resources. It is also called maritime engineering. Construction and pre-commissioning is typically performed as much as possible onshore. To optimize the costs and risks of installing large offshore platforms, different construction strategies have been developed. One strategy is to fully construct the offshore facility onshore, and tow the installation to site floating on its own buoyancy. Bottom founded structure are lowered to the seabed by de-ballasting see for instance or , whilst are held in position with substantial systems. The size of offshore lifts can be reduced by making the construction modular, with each module being constructed and then lifted using a into place onto the platform. A number of very large crane vessels were built in the 1970s which allow very large single modules weighing up to 14,000 tonnes to be fabricated and then lifted into place. Specialist floating hotel vessels known as are used to accommodate workers during the construction and hook-up phases. This is a high cost activity due to the limited space and access to materials. Both of these types of vessel are constructed in marine yards but are often involved during the construction phase to pre-drill some production wells. Other key factors in offshore construction are the which defines periods of relatively light weather during which continuous construction or other offshore activity can take place. The basket is lowered to the water level, then the divers enter the water from it to a maximum of 120 feet 40 m. Bells can go to 1,500 feet 460 m , but are normally used at 400 to 800 feet 120 to 240 m.
