Wärtsilä to Design Heavy Construction Vessel for Subsea 7

Wärtsilä, a marine industry solutions and services provider, has been contracted to provide the design for a large heavy construction vessel (HCV). The ship is to be built for Subsea 7 S.A., the seabed-to-surface engineering, construction, and services contractor to the offshore energy industry worldwide, by Hyundai Heavy Industries (HHI) in South Korea. HHI is one of the world's largest ship building companies.

Wärtsilä Ship Design's VS 4285 HCV design will be one of most capable heavy construction vessels in Subsea 7's fleet of over 40 ships, the company claims. 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 finalizing 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. 

According to Wärtsilä, important features of the design include dynamic positioning (DP) capabilities, as well as an efficient hull form.
