When loaded aboard Mighty Servant 3 for trip from Rotterdam to Norfolk, floating drydock acquired recently by Colonna yard had overhang of about 114 feet. Colonna's Shipyard In Norfolk Gets Floating Dock From Holland Colonna's Shipyard, Inc. in Nor- folk, Va., recently acquired a float- ing drydock 571 feet long and 118 feet wide to enhance its ship-repair- ing capabilities. Formerly Dock No. 5 of the Amsterdam Drydock Com- pany in the Netherlands, the big dock was transported across the At- lantic aboard the Mighty Servant 3, a semisubmersible heavy-lift vessel operated by Wijsmuller Transport B.V. of IJmuiden, Holland. The Dutch transportation and towing company is represented in the U.S. by Wijsmuller (U.S.A.) Inc. of Houston. Wijsmuller operates a fleet of eight heavy-lift, self-pro- pelled vessels similar to the Mighty Servant 3. The dry transport method was chosen because a trans-Atlantic wet tow would have required extensive and expensive strengthening of the dock. Even then, it would have been necessary to remove two sections of the dock for a wet tow. The Mighty Servant 3 has a flat unobstructed deck 459 feet long and 132 feet wide. When loaded aboard the vessel, the 571-foot-long dry- dock had an overhang of 114 feet. Loading of the dock took place in Rotterdam harbor. The dock had been there for some time to undergo inspections on behalf of the new owner. For the loading operation, the Mighty Servant 3 was partially sub- merged by pumping water into her ballast tanks. With the deck under water, the drydock was positioned precisely and the ballast tanks were pumped, bringing the vessel back to its normal draft. The procedure was reversed for the unloading in Nor- folk.
