OFFSHORE WIND

GLDD is fully engaged in the rapidly developing offshore wind market in the U.S. Our first step in this effort is the investment into the build of the first U.S.-flagged Jones Act-compliant, subsea rock installation vessel (SRI) for wind turbine foundations. Currently under construction, our SRI vessel will set new standards for efficiency and innovation with its large capacity, accurate placement technology and cutting-edge battery and alternative fuel systems. This unique, technologically advanced vessel is an essential step towards building the marine infrastructure required for this new industry, which holds so much promise for our nation economically and environmentally. This vessel will service America’s growing offshore wind energy industry and help reach the Biden administration’s ambitious goal of 30 GW of offshore wind generation by 2030 which is estimated to service more than 10 million American homes.

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.
