Mammoet to Upgrade Hawaii Dry Dock for Navy Vessels

Mammoet has secured a contract with Dragados/Hawaiian Dredging/Orion JV to handle transportation and lifting for the upgrade of Dry Dock 5 at Pearl Harbor, Hawaii. This project, part of the Navy’s Shipyard Infrastructure Optimization Program (SIOP), aims to modernize the Pearl Harbor Naval Shipyard to better support the U.S. Pacific Fleet’s nuclear-powered submarines.

Mammoet will use specialized equipment to transport and lift heavy dry dock floor sections, each weighing over 4,000 tons. Foundation work has begun, with project completion expected by late 2027. The new, deeper dry dock will replace the existing one and accommodate Los Angeles and Virginia-class submarines.

Pierre Mille, Mammoet’s Sales Manager, expressed enthusiasm for the project, highlighting the company’s expertise in heavy lifting and transport. He emphasized Mammoet’s commitment to efficient and high-quality execution.

The upgraded dry dock is expected to have a long lifespan, continuing Mammoet’s legacy of contributing to significant naval infrastructure projects.
