Guam – The Marine Log website has posted some intersting notes on how the Resolve Marine Group helped re-float Guam Shipyard’s dry dock on March 3ed.
The 825 ft floating dry dock spent 2 months underwater after sinking on January 2 after workers left hatches open during a High Surf Warning.
Resolve was the successful bidder for the salvage job which, according to the posting on Marine Log, began the salvage work on January 31 and successfully refloated the dry dock on March 3.
The article says the dry dock was submerged at a depth beyond normal operating limits and “great care had to be taken to minimize hydrostatic pressures on tank boundaries during the refloating, and to keep global hull stresses and stability within allowable limits.”
In addtion, Marine Log reports that because of “extensive maintenance being performed on the dry dock prior to sinking, a large portion of its pumping system was inoperable,” and in order to overcome that challenge “Resolve mobilized 12 high-capacity electric salvage pumps,” and “numerous gauging systems were established to monitor tank pressures and condition throughout the refloating operation.”
