海上平台通常由下部支撑结构(如导管架)和上部设施组成。过去,设计人员总是考虑如何将导管架的重量减轻1%或2%,却忽略了对上部设施重量的控制,结果平台上部设施越来越复杂、庞大,生产费用也随之增加。现在油价下跌,为节省开支,设计者不得不采用减轻平台重量的办法来降低生产设施的 Offshore platforms usually consist of a lower support structure (such as a jacket) and a superstructure. In the past, designers had always considered how to reduce the weight of the jacket by 1% or 2% while ignoring the control of the weight of the upper part. As a result, the upper part of the platform became more complicated and bulky, resulting in higher production costs. Now that oil prices have dropped, to save money, designers have had to reduce the weight of the platform by reducing the weight of their production facilities
