Described centered cylinder comprises: centered cylinder housing, centerwell, brace panel muscle structure.Centerwell is installed on the centered cylinder enclosure interior by brace panel muscle structure.
Described truss structure comprises: no introversion is found leg, triatic stay, brace, is hung down and swing plate.No introversion is found leg, triatic stay, brace and is interconnected to constitute truss, hangs down to swinging on the diverse location that plate level is connected in space truss structure, along the vertical bay that truss structure is divided into four equal heights.
Described hanging down swung plate, and its middle part is provided with the standpipe support.
Described soft cabin comprises inner ballast, cabin body.
The invention has the beneficial effects as follows: the multiple column truss type spar platform system that a kind of band centerwell of deep-sea oil gas development of resources is provided; its buoyancy is provided by hard cabin; centerwell is arranged in the centered cylinder; be convenient to install buoyancy tank so that the vertical support of top tensioned riser to be provided; because riser systems is with the platform motion decoupling zero; be subjected to the protection of main platform body simultaneously; thereby can keep less motion; and be subjected to less environmental load; thereby can on this platform, can use and do the oil-collecting tree, be convenient to the installation and maintenance of equipment.The standpipe support swing installation in plate and the hard cabin of hanging down be convenient to tensioned riser by and horizontal support is provided.
