Abstract：

Jacket offshore installation is one of the most important parts in offshore oil and gas fields’ development.In general, one floating crane is used for offshore operation.For the project with tight installation period and narrow operating window, it is of positive significance to adopt two floating cranes for joint works to shorten the installation period.In view of the traditional operation mode and the joint mode of two floating cranes for Jacket offshore installation, quantitative analysis and study have been carried out for installation duration and ship/days, and through the engineering practice, it is confirmed that the joint mode of two floating cranes can significantly shorten the installation duration and has a certain promotional value.
