Wärtsilä provides design for Subsea 7 HCV newbuild

JUNE 6, 2013 —  The newbuild heavy construction vessel (HCV) ordered by Subsea 7 at South Korean shipbuilder Hyundai Heavy Industries last month (see previous story) will be built to Wärtsilä Ship Design’s VS 4285 HCV design.

It will be one of most capable heavy construction vessels in Subsea 7’s fleet of over 40 ships and 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 the shipbuilder, 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.

“We have enjoyed a successful co-operation with both Subsea 7 and HHI, major players in their industries. This latest order follows the contract that Wärtsilä received last year to design a dive support vessel (DSV) for Subsea 7, which is also being built by HHI. It clearly indicates the confidence that the industry has in Wärtsilä Ship Design’s offering. Our way of working is based on deep understanding of the clients demand and the operating profile of each vessel in question and prepare the design accordingly,” says Riku-Pekka Hägg, Vice President Wärtsilä Ship Design.
