Marine construction floating platform

By weight of the platform itself is sit tight on solid seabed soil. At the bottom of this platform is a reinforced concrete caissons or more base with steel or reinforced concrete columns supporting the upper deck on the base uprights. Since the whole structure is relatively large, the general construction of the first excavation of mud on the shore dock base, have again and again to the deep cover then high, then floated to the site, load sinking. At present this platform is generally used as a subsea storage tanks or offshore oil drilling. Its main feature is to withstand storms and wave attack capability, durability and low maintenance cost structure, but need to shore dock pit excavation and construction have deepwater coastal waters, so the structure is highly restricted.

Floating offshore platform

1. Bottom-platform (also known as the ups and downs platform) used for water depths shallower waters, the upper part of the working deck, the lower part of the mat serves as pontoon, with the intermediate support pillar or trusses. When the job, to float inside the water so that it is located seabed; after operation, the water out of the box, raised platforms on their own buoyancy.

2. Jack up accommodate a large range of water depths, in the state of Floating Barge, its four sides provided with a plurality of cylindrical type or root truss leg, gear, rack or hydraulic lifting mechanism control. When the job, down leg and inserted into the seabed to a depth so that the bottom of the boat out of the water, became the working deck. After the operation, lowering the hull, uprooted leg, you can drag Hangzhi new location. Leg on the bottom box Shen said pad mat jackup without mat, said stub jack up.

3. Semi-submersible platform used for large depth of the sea, but also the lower floating structure consists of working the upper deck, in the middle column or truss three parts. Lower floating structure is divided disembark asana and pontoon type two, disembark style more conducive to sailing, so the new construction of self-propelled semi-submersible platform, multi-body dual disembark. This semi-submersible platform in the job status using anchor positioning or dynamic positioning. After the operation, the discharge of ballast water tanks, floating waterline to towage, anchor close to the shift. Over the past few semi-submersible platform built by both bottom-function, it can also be located subsea operations in shallow waters.

4. Boat platform (ie, drilling rigs) is on an ordinary ship plus a work platform, the ship has a double and a single body of the points, can generally be self-propelled, using anchor positioning or dynamic positioning operations. Currently Floating Platform can be migrated to offshore oil and gas exploration in most applications.
