Wärtsilä has been contracted to provide the design for a large heavy construction vessel (HCV). The ship is to be built for Subsea , by Hyundai Heavy Industries (HHI) in South Korea.

The VS 4285 HCV design will be one of most capable heavy construction vessels in Subsea 7's fleet of over forty ships. The vessel will be deployed globally to meet increasing market demands for executing ever larger and more complex projects. It is designed for operating efficiently in deep and ultra deep waters and in harsher environments.  

The new HCV will be capable of operating on a year round basis. In finalising the design, close cooperation between Hyundai Heavy Industries as builder, Huisman for the crane and vertical laying system, and MAATS as supplier of the carousel, was essential in meeting the requirements set by Subsea 7.  

Important features of the design include the good dynamic positioning (DP) capabilities, as well as an efficient hull form.
