Seven Arctic 

Wärtsilä, the marine industry’s leading solutions and services provider, has been contracted to provide the design for a large heavy construction vessel (HCV).

Wärtsilä Ship Design’s VS 4285 HCV design is one of most capable heavy construction vessels in Subsea 7’s fleet of over 40 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.

“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,”

Riku-Pekka Hägg, Vice President Wärtsilä Ship Design
