With the continuous emergence of mega marine projects in China,new specialized ships have been invented and put into use.However,the per-shift cost of new type ships is not included in the current industry quota system of the country,which makes it impossible to reasonably calculate the engineering cost.Therefore,it is imperative to determine the cost and calculation method of per-shift cost of new type ships.By combining related industry specifications with the actual situation of the Shenzhen-Zhongshan Link project and referring to the current national quota of per-shift cost composition,this paper studies the values and calculation methods of key parameters in the per-shift cost of integrated ships for floating transportation and installation of immersed tubes,formulates a calculation formula for the per-shift cost,and verifies the accuracy of the formula through the actual cost incurred and the current quota,which can provide reference for the compilation of per-shift cost of new type ships in the future.
