The towage design plan and implementation of the"Deep Sea No.1"semi-submersible production and storage platform face many technical difficulties such as long towage distance,severe environmental conditions,few tug resource options and high operational risks.After comparing the dry tow method with the wet tow method,the wet tow method was adopted.The main issues and key matters during wet tow,including wet tow to site route,towing draft,wet tow resistance and tug arrangement were analyzed.The feasibility of wet tow plan was verified by the wave basin model test.The long-distance wet towing of the"Deep Sea No.1"platform was successfully implemented.
