Problems solved by technology

When the impact force of the supply ship reaches a certain value, the platform column will be breached, which will lead to catastrophic consequences, ranging from tens of thousands of yuan in losses to casualties and losses in millions, tens of millions or even billions of dollars. , a large number of indirect losses are even more difficult to predict

Embodiment Construction

[0040] Such as Figure 1 to Figure 11 As shown, the present invention is a large-scale floating anti-collision device suitable for the seventh-generation ultra-deepwater drilling platform, which mainly includes a plurality of anti-collision units nested opposite to the column of the ultra-deepwater drilling platform. The anti-collision buoy box 2, the energy-absorbing assembly 5 arranged inside and outside the anti-collision buoyancy box, the buoy type platform 3 and the connection assembly 4 opposite to the back side of the collision are composed. Such as figure 1 As shown, when the ultra-deepwater drilling platform 1 is in the working condition, the buoyancy tank 12 and the cross brace 14 of the ultra-deepwater drilling platform are both at a deep draft, and there is no possibility of ship collision. The outside of the drilling platform 1 is a key part of the ship collision accident, and corresponding anti-collision devices need to be installed to protect the columns from d...

Abstract

The invention discloses a combined pontoon anti-collision device for ultra-deep water drilling platforms. The device comprises an anti-collision device and a floating drum type platform; the anti-collision device and the floating drum type platform are connected by a connecting member to form a ring structure; the ring structure is set on pillars of the ultra-deepwater drilling platform; the anti-collision device comprises an anti-collision pontoon which is provided with an energy absorbing assembly. The composite pontoon anti-collision device suitable for ultra-deepwater drilling platforms of the invention is characterized in that the main body of the anti-collision device is an anti-collision pontoon unit whose cross-sectional shape is a right-angle trapezoid and which reduces the forward impact force. It can provide enough buoyancy without additional power to fix the device in the face of impact of columns, and no auxiliary structure should be added to the ultra-deep water drilling platform column to match the installation and fixation of the collision avoidance device, which reflects the advantages of economic new type and good applicability.

Description

technical field [0001] The invention relates to a combined floating tank anti-collision device suitable for an ultra-deep water drilling platform, and belongs to the technical field of marine engineering. Background technique [0002] With the continuous deepening of human development and utilization of oil and gas resources, oil and gas exploration and development have successfully shifted from land to coastal areas and to deep sea. When the proportion of existing oil reserves is constantly increasing, it is imminent to explore new oil resources. The ultra-deepwater drilling platform, as the main production facility for deep-sea oil exploration, has taken on this important task. [0003] As the basic facilities for the development of offshore oil resources, offshore platforms have been in complex and harsh marine environments for a long time. In addition to normal working loads and environmental loads, offshore platforms are often subjected to accidental loads such as shi...
