“30 by 30” is the rallying cry for all concerned with the burgeoning U.S. offshore wind business. In Spring 2021, the Secretaries of Energy, Interior and Commerce resolved to deploy 30 gigawatts (GW) of electricity generated from offshore turbines by 2030. Consultants McKinsey, in a recent article frame the value proposition for this clean fuel source, writing: “During the industry’s 30-year evolution, costs have fallen so sharply that offshore wind now compares favorably with competing energy sources.” For vessel owners, renewable energy brings opportunity.The thrust of near-term U.S.

Damen Shiprepair Dunkerque Completes Project

Damen Shiprepair Dunkerque (DSDu) has completed an eight-day refurbishment project for the 132-metre DP2, self-propelled, jack-up vessel Sea Installer. Operated by A2SEA, which was purchased in 2017 by DEME’s subsidiary GeoSea, Sea Installer was purpose-built in 2012 for installing the next generation of large wind turbines off the coast of Europe. The primary task was the fitting of new spud can shoes to the vessel’s four columnar legs. These massive pieces of steelwork, weighing 160 tonnes each, required the deployment of specialist logistics including the use of self-propelled modular transporters to move them into position and a 700-tonne crawler crane. While Sea Installer was in the drydock at DSDu, the client also took the opportunity to prepare her for the next contract.

Damen Shiprepair Amsterdam (DSAm), part of Damen Shiprepair & Conversion, is currently undertaking a modification and maintenance project on the jack-up vessel Sea Installer. In what is a multidisciplinary project, the yard’s primary focus will be to upgrade the vessel’s main crane. With its increased lifting capacity, the 132-meter A2SEA-owned vessel, which is used chiefly for offshore wind farm installation purposes, will be able to take on a broader scope of work as offshore wind activities involve heavier and larger components.
