Problems solved by technology

If a large floating crane is used, due to the limitation of the floating crane capacity, the large blocks need to be installed in blocks, which will make the floating crane operation time longer and the installation cost more expensive

Abstract

The invention discloses a catamaran for an ocean engineering, which comprises two floating bodies which are relatively arranged, wherein a space is arranged between the floating bodies; the two floating bodies are connected with each other through at least one box body, and the box body is fixedly arranged on the top parts of the floating bodies; and a slideway is arranged between the box body on the top parts of the floating bodies and the tail end of the catamaran. The catamaran has a fender protection function, so the impact between the catamaran and a platform is greatly reduced; and the catamaran adopts a conventional hull mode, has a simple structure, and is convenient and practical. The catamaran provided in the invention is applicable to the installation and dismantling operations of platform modules of various types, and can be widely applied for offshore oil exploitation, so a new ship resource is particularly provided for deepwater oil-field development.

Description

technical field [0001] The invention relates to a catamaran used for ocean engineering. Background technique [0002] As my country's offshore oil development moves towards deep water, various types of platforms emerge as the times require, and the scale of the platforms is getting larger and larger, and the weight of the platform blocks is also increasing. At present, the installation of platform blocks is generally carried out by large-scale floating cranes or by single-vessel floats. If a large floating crane is used, due to the limitation of the floating crane capacity, the large blocks need to be installed in blocks, which will make the floating crane work longer and the installation cost more expensive. If single-vessel float-over operation is used for installation, the requirements for the environmental conditions of the installation sea area and the capacity of the barge are relatively strict, and the requirements for the scale of the lower support structure are ver...
