Embodiment Construction

[0033]In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings. In the description of the tension leg platform that can be equipped with wide buoyancy tanks—WTLP of the present invention, it should be understood that terms such as "front", "rear", "upper" and "lower" are only for the convenience of describing the technology of the present invention The scheme, rather than indicating that the device or element referred to must have a specific orientation, and therefore should not be construed as limiting the invention.

[0034] like figure 1 As shown, in a preferred embodiment of the present invention, the tension leg platform (WTLP) that can be equipped with a wide buoyancy tank is equipped with four major parts: the upper block 1, the lower floating body, the tension leg system 5 and ...

Abstract

The invention discloses a tension leg platform capable of being provided with wide pontoons, for short, WTLP. The tension leg platform capable of being provided with the wide pontoons comprises an upper module, lower floating bodies, tension leg systems and bottom foundations. Stand columns are arranged on the lower side of the upper module and support the upper module. A plurality of tension legs are arranged on bottom corners of the lower floating bodies to be connected with the bottom foundations, and the tension legs provide downward pull force for the platform to fix the platform. According to the WTLP, since square-to-circular transitional section connecting structures are arranged between the round stand columns and the square pontoons, the pontoons can be designed wider to increase bottom buoyancy and improve self-floating stability on the basis of adopting the round stand columns to guarantee the in-place performance of the platform, the upper module and the lower floating bodies can be integrally built in wharfs and building sites where the fairway depths are limited, and a wet-dragging transporting mode can be adopted; and meanwhile, the design of the wide pontoons enables the pontoons to be thinner, and thus current loads borne by the platform when the platform is in place can be decreased advantageously, and the in-place performance of the TLP is improved.

Description

technical field [0001] The invention relates to a tension leg platform, which belongs to the field of marine engineering, in particular to a tension leg platform on which a wide buoyancy tank can be arranged. Background technique [0002] The tension leg platform is a typical deep-water floating platform, referred to as TLP (Tension Leg Platform), which generally consists of four parts: the upper block, the lower floating body, the tension leg system, and the bottom foundation. The tension leg platform provides sufficient pretension for the tension leg through the residual buoyancy of the lower floating body, so that the tension leg is always in a tensioned state, so that the movement of the platform outside the plane (rolling, pitching, heaving) is close to Rigid, while in-plane movements (sway, surge, yaw) show flexibility, becoming a semi-compliant platform for vertical mooring. Since the natural frequency of motion of the tension leg platform in each degree of freedom i...
