Resolve Marine Group, Inc. successfully refloated the Perseverance dry dock in San Juan, Puerto Rico on October 27. The dry dock sank on September 29 during maintenance/refit operations. During the sinking, the dry dock’s internal pumping system became inoperable due to flooding of the dock’s control station.
Internal damage sustained during the sinking degraded the stability of the dry dock.
Resolve was engaged to assess the casualty, and plan and execute the refloating.
First, 12 electric submersible pumps were installed to replace the dry dock’s inoperable pumps.
Resolve then used the RMG 400 sheer leg heavy lift crane barge to maintain longitudinal stability of the structure during the 8-day refloat operation.
Resolve had deployed the AHTS Resolve Pioneer, the tug Lana Rose and RMG 400 heavy lift crane barge to the Perseverance refloat operation after completing the refloating and scuttling of the Angeln container vessel wreck off the coast of St. Lucia.
San Juan Towing & Marine Services, the owner of the Perseverance dry dock, is a resource partner within Resolve’s network of OPA 90 service providers.
