Semi-submersible living platform

Abstract

The invention provides a semi-submersible living platform, comprising a lower floating body, a column supported on the lower floating body and a main hull supported on the column, the lower floating body is flat, the cross section of its main body is rectangular, and the height The ratio to the width is 0.52~0.62; the width of both ends of the bow and stern of the lower floating body is smooth and tapered toward the end. In the present invention, the lower floating body adopts a flat structure and has a small aspect ratio coefficient, which can avoid the area where wave energy is concentrated, increase the natural period of the platform heaving motion, and make the platform's motion performance and the air pressure on the lower surface of the main hull The gap and slamming are improved, and the safety of the semi-submersible living platform is improved; at the same time, the low-coefficient aspect ratio structure of the lower floating body relatively increases the bottom area of ​​the lower floating body, which is beneficial to the shallow water towing of the platform or the use of cranes. transport. In addition, the streamlined structure at the bow and stern of the lower floating body is also conducive to reducing the flow resistance suffered by the platform, reducing fuel consumption during sailing conditions, and reducing costs.

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...

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
