Ulstein continues work on GLDD’s new rock installation vessel

Following the basic design contract in December 2020, Great Lakes Dredge & Dock Co. LLC (GLDD) has now contracted Ulstein to continue the project with the integration engineering for their new dynamically positioned rock installation vessel.

This contract is the next step in realising the first Jones Act compliant subsea rock installation vessel to serve the U.S. market.

The scope of work includes the selection of vessel main equipment with integration engineering plus the start of detail design.

Awarding this contract is intended to advance the engineering work, ensuring the vessel is on schedule to meet its operational target of Q2 2024.

“It is a privilege to work with Ulstein on this landmark project as they continue to bring global best practices, expertise and creativity to the design of this first-of-its-kind U.S. vessel,” commented Mike Greenwood, sr. project sponsor at GLDD.

“All credits to both GLDD and Ulstein project teams that have been working on this project since June 2020 from their home offices. Ulstein’s strength and added value to customers is reflected in this engineering contract. It is the result of the close cooperation between our design and engineering teams in the Netherlands, Norway and Poland and using Ulstein’s long shipbuilding competence,” added Edwin van Leeuwen, managing director at Ulstein Design & Solutions BV.

The vessel will be built at a yet-to-be-selected US shipyard. To meet general US working practices, Ulstein therefore developed the design completely in the imperial system, rather than converting metric dimensions at a later stage.
