Semi-submersible living platform

Abstract

The invention provides a semi-submersible living platform. The semi-submersible living platform comprises lower floating bodies, stand columns which are separately supported on the corresponding lower floating body, and a main hull supported on the stand columns, wherein each of the lower floating bodies is flat; the cross section of the main body of each lower floating body is rectangular, and a height-width ratio is 0.52 -0.62; and the width of a bow end and the width of a stern end of each of the lower floating bodies are separately, smoothly and gradually reduced in the direction of the corresponding end part. According to the semi-submersible living platform disclosed by the invention, each of the lower floating bodies adopts a flat type structure and has a small height-width ratio coefficient, so that the area where the wave energy is concentrated can be avoided, the natural period of the heave motion of the platform is prolonged, the movement performance of the platform, the air gap of the lower surface of the main hull and slamming on the lower surface of the main hull are improved, and the safety of the semi-submersible living platform is improved; besides, the bottom area of the lower floating bodies is relatively increased by the small-coefficient-height-width ratio structure of the lower floating bodies, so that the platform is conveniently towed in shallow water or is transported by a crane ship; and in addition, the streamlined structures of the bow ends and the stern ends of the lower floating bodies also contribute to reducing the flow resistance borne by the platform and the fuel consumption during navigation conditions is reduced, so that the cost is reduced.

Description

technical field [0001] The invention relates to the field of marine engineering equipment, in particular to a semi-submersible living platform, which is used to provide support for crew members who carry out oil and gas exploitation, storage and processing operations in middle and deep waters. Background technique [0002] As we all know, petroleum and electric power resources are the power source of modern industry. With the increasingly poor land petroleum resources, the exploration, development and utilization of offshore oil and gas resources have been developing rapidly in recent years, which has led to strong demand for quality and quantity of marine engineering products, especially With the floating production system replacing the fixed platform and marine engineering gradually moving from shallow water to medium-deep water, medium-deep water marine engineering equipment such as semi-submersible drilling platforms, single-hull floating production systems, multi-functio...

AI Technical Summary

Problems solved by technology

[0003] In the middle and deep waters far away from the mainland, the sea conditions are often more complicated, and it is necessary to face harsh weather conditions and sea conditions, which can easily cause the living platform to roll and heave too much, causing discomfort to the crew and affecting the safety of the platform sex
