Dynamic Supports Cost-Saving Maintenance Evolution for ACU-2 Craft

JOINT EXPEDITIONARY BASE LITTLE CREEK-FORT STORY - The Mid-Atlantic Regional Maintenance Center (MARMC) auxiliary floating dry dock Dynamic (AFDL 6) successfully completed a docking and undocking evolution for Landing Craft Utility (LCU) 1654, assigned to Assault Craft Unit (ACU) 2 at Joint Expeditionary Base Little Creek-Fort Story.

The docking evolution enabled LCU 1654's crew to conduct critical maintenance, including a full-jacket water system flush for two main propulsion engines and three Ship Service Diesel Generators (SSDG), welding repairs to the port and starboard KORT nozzles-a ducted propeller assembly for marine propulsion, and the replacement of both port and starboard waterborne shaft sections.

Throughout the evolution, Dynamic provided essential services including shore power, low-pressure air, welding support, crane operations, security, and environmental mitigation.

"Dynamic was able to plan, brief, and execute an emergent docking within a 72-hour notice -typically a 10-day minimum process for us - enabling ACU-2 to get their asset out on time to support the Atlantic Alliance," said Dynamic Commanding Officer, Lt. Cmdr. Jeremy Mayfield.

According to ACU-2 leadership, executing the work aboard Dynamic resulted in a cost savings of approximately $124,400 compared to commercial dry dock alternatives.

Mayfield added, "The Dynamic team's expertise and professionalism enabled this to be successful and coordinate with all outside entities on short notice to support a safe and efficient evolution."

The mission underscores the ongoing strategic value of afloat maintenance capabilities and the ability of Navy assets like Dynamic to deliver flexible, cost-effective support in direct alignment with Fleet readiness objectives.

MARMC, a field activity under Naval Sea Systems Command (NAVSEA), provides surface ship maintenance, management and oversight of private sector maintenance and fleet technical assistance to ships in the Mid-Atlantic region of the United States.
