March, 1927 ca AGWISUN after devastating HE tanker AGWISUN, sunk dur- ing an explosion in Brooklyn last year, was raised Jan. 22 and towed to the Robins plant of the Todd Shipyards Corp. to whom the contract for the repairs has been awarded. The accompanying: illustra- tions show the completely shattered condition of the vessel. Surveys developed that the entire ship, from amidships quarters to the boiler room casing aft, had been prac- ww & explosion MARINE REVIEW Rebuild Wrecked Tanker moved into drydock at Robins tically destroyed. The back of the vessel was broken and she was draw- ing 13 feet forward, 19 feet aft and 24 feet amidships. Temporary repairs had to be made before it was pos- sible to move her. To float the vessel to a draft that would permit her to be dry docked was unusually difficult, as it was feared that, owing to her weakened amidships section, should she be pumped out too far amidships she c— ak 33 would crack and break the other way, dropping her stem and_ stern deep down and leaving amidships light. To prevent this, heavy steel hawsers were stretched from her fore- castle head, over the bridge, to the poop deck and a heavy channel was secured on the right over the break. Huge gaps in the tanker’s sides were covered with heavy rope mats and canvas wedged under steel wires that had been stretched for the pur- pose. These patches were necessarily flexible to permit the working of the ship as she was pumped out. These precautions permitted the successful raising of the vessel to about a 16-foot depth and then a favorable tide was awaited to place the AGWISUN in the graving dock. To insure her passing safely through the entrance of the dock, two large steel pontoons were placed under her after quarter, one on the port and one on the starboard side. Each pontoon had a lifting power of 50 tons. Supplementing this, a float- ing derrick was alongside lifting on a sling under the stern frame arch. Cribwork was ready on the drydock floor and the tanker settled down straight and true, ready for the skill of the ship surgeons that will make her ready for sea again with- in four months of the time she was raised. The AGWISUN is owned by the International Shipping Corp. and will when completed be in every respect practically as good as new. The con- tract price for the work is said to be about $475,000.
