GLDD Approach Overview

Build and protect the foundations of offshore
energy and critical subsea infrastructure.

Port of New York and New Jersey harbor deepening program

The county, in partnership with local municipalities, has embarked on a plan to restore and preserve the fragile coastline while establishing a strong defense against increasingly powerful storms to protect property and infrastructure in the coastal communities.

  • Completed in 2065

How GLDD Will Impact The Offshore Energy Industry

Offshore energy relies on stable, protected subsea infrastructure. Wind turbine foundations, power and data cables, and pipelines operate under constant pressure from ocean forces, seabed movement, extreme weather and external impact.

Without long-term seabed stabilization and protection, these critical systems face increased risk, downtime and costly disruption. As offshore energy development accelerates, the integrity of the infrastructure below the surface becomes essential to long-term reliability and economic stability.

Subsea rock installation is the most effective means of providing long-term scour protection. It is required to stabilize the sea floor around marine structures from the momentous kinetic energy of the ocean eroding away critical structural foundation base. With the first, and only, Jones-Act compliant subsea rock installation vessel under construction at the Philly Shipyard in Philadelphia, GLDD is helping to strengthen the foundations for U.S. offshore energies.
