Analysis and Advice on Impact Factors of Outfitting Weight Reduction for Offshore Fixed Platform Living Quarters Module

Abstract

Abstract:

With the continuous development of Chinese offshore engineering towards deeper water, more attention is paid to the economy of offshore platforms. The weight of an offshore platform is an important factor that influences its economy. The weight of platform topside greatly influences the weight of the sub-structure, while living quarters is one of the most important parts of the topside. After analyzing all kinds of cabin furniture and outfitting materials of a 90-person living quarters, it is pointed out that the rational utilization of light-weight and good-performance new materials can reduce the overall outfitting weight, which in turn leads to the weight reduction of the platform topside and consequently improves the economy performance of the sub-structure.

Key words: offshore platform, living quarters, outfitting new materials, weight reduction
