OFFSHORE WIND
Offshore wind will play a crucial role in helping the U.S. meet its decarbonization and renewable energy goals. This dynamic and emerging industry is expected to see a dramatic expansion across the U.S. shores over the next decade and will help to provide a reliable and clean energy source that will allow our nation to achieve a sustainable future.

GLDD’s Critical Role in Realizing Offshore Wind’s Potential
Subsea rock installation, known as scour protection, is required to stabilize the sea floor around marine structures. With the first, and only, Jones-Act compliant subsea rock installation vessel under construction at the Philly Shipyard in Philadelphia, GLDD is helping build the foundations for U.S. Offshore Wind.
Among its leading-edge technologies to better protect the environment, the vessel will have EPA Tier 4-compliant engines, a battery pack to shave peak loads, and plug-in capability to obtain shore power while loading. Additionally, it will be able to run on biofuel, reducing the ship’s CO2 footprint and is equipped with active emissions control technology to mitigate NOx emissions.
Best-in-Class, Purpose-built Offshore Wind Construction Vessel
World-renowned engineering firm Ulstein Design and Solutions B.V. was commissioned by GLDD to design the vessel using state-of-the-art technology, equipment, environmental controls, and automation. The design has been reviewed and approved by the American Bureau of Shipping (ABS) and will be built with best-in-class safety, environmental and emissions standards, expected to be sea-ready by Q4-2024.
It will be awarded the ABS SUSTAIN-2 Notation, recognizing adherence to certain UN Sustainable Development Goals related to vessel design, outfitting and layout. The ABS SUSTAIN Notations establish a pathway for sustainability certification and reporting.

ADVANCED TECHNOLOGY
- Best-in-class air-quality controls to adhere to EPA Tier 4 emissions standards
- Ability to run on biodiesel for lower emissions
- Work-class ROV capabilities
- Loading Capacity of 20,000mT (2 x 10,000mT bins)
- Dynamic Positioning System (DP2)
- Scour protection with an active heave compensated fallpipe
- Advanced multi-beam survey capabilities
The vessel represents a critical advancement in building the future of the new U.S. offshore wind industry, including establishing a U.S.-based rock supply chain network spanning eastern seaboard states with active offshore wind leases – expected to spur additional job growth and regional economic opportunities.
