As a key part of position mooring system， connectors have been widely used for the joining of mooring lines with floating structures or different mooring components. Recently， with the development of floating offshore wind， multiple demonstration projects have been reported worldwide and large scale projects are under planning. The cost must be controlled for the floating wind to realize commercialization by technological innovation， including the mooring system. The mooring connectors have been utilized and verified in the offshore industry for the last several decades and played an important role in connection， installation， maintenance and replacement of mooring system. With the development and flexible application of the mooring connectors， the design， fabrication and installation of floating wind turbine could be significantly improved and the cost of floating wind will be effectively reduced.
