Horizontal lower floating body semi-submersible platform

Abstract

The invention discloses a semi-submersible platform with a horizontally downward floating body. The semi-submersible platform comprises a downward floating body, vertical columns 3 and an upper hull 4, wherein the vertical columns 3 are supported on the downward floating body, and the upper hull 4 is supported on the vertical columns 3. The downward floating body comprises the horizontally downward floating body 1 and a vertically downward floating body 2, the floating bodies are of a rectangular box type and are structurally vertically and horizontally crisscross and integrally symmetric, and the vertical columns 3 are arranged at vertically and horizontally crisscross points and are symmetrically arranged on the whole platform. The platform is excellent in movement performance, has unconditional stability, is adaptable to wide operating water depth range, fine in overall structural strength and low in operating energy consumption, and can be applied to production and living material storage and transfer and material supply for short and open seas and island construction and development under coastal environment conditions.

Description

Technical field [0001] The invention relates to a living platform that satisfies the functions of marine life production, logistics support, and nearshore or island construction, in particular to a semi-submersible living platform suitable for deep sea or nearshore sea conditions. Background technique [0002] During the development of near and distant islands and reefs and the protection of rights in the distant sea, restricted by geography and marine environment, the storage and transportation of materials for production, living and construction, as well as the supply of living materials such as fuel and fresh water, have been greatly restricted. The semi-submersible production, life and logistics support platform provides services such as accommodation, food, medical care, entertainment, etc. for the above activities, and also provides a platform for material storage, transportation and transfer. [0003] Under the existing technology, the general ship type of the semi-submersib...

AI Technical Summary

Problems solved by technology

The relatively weak tubular cross brace bears the longitudinal shear force and transverse separation force from the vertical lower floating body, and is prone to strength failure, especially the structure at the junction of the cross brace and the column is a part that is prone to fatigue. Being compromised will seriously jeopardize the security of the entire platform

[0004] The existing semi-submersible life support platform mainly serves in the deep sea environment, far away from land and islands, and the staff and supplies need to be transported and delivered over long distances. In addition, since the main deck of the platform is much higher than the sea surface, transport ships cannot approach the platform. , can only use helicopters to transport personnel and supplies, resulting in huge operation and maintenance costs
