Coastal Protection & Restoration

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.
