Syncrolift Elevator Drydock

Expansion Completed At

Singapore Shipbuilding Facility

The Singapore Shipbuilding and Engineering Ltd. Syncro- lift is shown prior to its recent expansion. At 3,600- long-tons capacity, it is one of the largest marine elevator drydocks in Southeast Asia. The vessel at right is berthed on the direct-side transfer area, part of the yard's extensive transfer network.

Expansion has been completed on one of

Southeast Asia's largest marine elevator dry- docks at the Singapore Shipbuilding and Engi- neering Ltd. facility.

Pearlson Engineering Co. of Miami, Fla., designers of the original dock which has been in operation for a year, said the 100-by-20- meter enlarged platform became operational in

December, with a new lifting capacity of 3,600 long tons.

The original design for the Syncrolift ma- rine elevator drydock and ship transfer facility at Singapore had provided for expansion to its present size, according to Raymond Pearlson, inventor of -the Tsystem now in use or under construction at 93 shipyards in 41 countries.

The overall shipyard complex at this natural deepwater shelter was coordinated by Singa- pore Shipbuilding and Engineering Ltd. The four-year-old 30-acre yard employs 1,000 de- signers, engineers, technicians and workers in its ship-repair and new construction complex.

The firm specialized in building fast-strike

Naval craft in the 350-ton-displacement range and has launched 96 vessels to date. The yard fabricates subassemblies under cover, which are erected on rolling cradles. When ready for launch, the vessel is transferred to the

Syncrolift platform for "controlled" launch- ing.

The yard reports that the risks involved in sliding ships downhill on old-styled timber tracks are no longer necessary, and the ex- pense and maintenance of launch ways has been eliminated.

For drydocking, the platform is lowered much like an elevator iby electrically powered and synchronized mechanical hoists to a pre- determined depth. The vessel is floated over the submerged platform and cradle, which are then raised to meet the hull. Remote-con- trolled blocks are then moved into position, after which the platform is raised to yard level.

The hull is then inspected and work to be done is evaluated. If extensive, the ship on its rolling cradle—-equipped with special sea- water submersible, sealed bearing wheels—can be moved ahead or to either side on the rails of the transfer network to an open or covered shore berth, as required.

This transfer technique immediately frees the lifting platform for the next drydocking.

With the Syncrolift, vessels can be raised or lowered at a speed of 30 centimeters per min- ute. This, combined with an efficient transfer system, permits the yard to handle several vessels in the course of a day.

The docking platform, as originally installed, was 60 meters long and 20 meters wide, with a lifting capacity of 2,230 long tons. Its origi- nal eight main lifting beams, which were re- tained, are of fabricated steel, averaging two meters in depth. Total weight of the original platform was about 500 tons.

Expansion was designed into the Syncrolift and provided for the addition of 10 hoisting units to the original 16, and the subsequent lengthening of the platform to 100 meters.

To keep the original as well as the expansion construction and installation costs to a mini- mum, local materials and labor were used whenever possible. The hoisting equipment and electrical controls for this installation were manufactured in the United States by Pearl- son Engineering Company, which provided all necessary design drawings and construc- tion plans.

Special Syncrolift hoisting units, electrical control center and components designed by

Pearlson Engineering, comply with the stand- ards of the American Bureau of,Shipping and

Lloyd's Register of Shipping, and are manu- factured in both the United States and Europe.

Applying maintenance procedures recommend- ed by Pearlson, the life expectancy of the system should exceed 40 years.

UNDER WAY AT JEFFBOAT: The bow of the new over- night passenger steamboat being built by the Delta

Queen Steamboat Co. as a sister ship to the Delta Queen is taking shape at Jeffboat, Inc., Jeffersonville, Ind.

The $15.5-million steamboat will go into operation in 1975. It will include 220 staterooms and will accom- modate 400 passengers in lower berths. Features of the boat include a swimming pool on the top deck, a sauna, four restaurants, a cinemascope movie theater, individually controlled sound and communications facili- ties in each room and four passenger elevators. The all-steel boat will be 379 feet long, with a breadth of 68 feet. It will rise 52 feet above the waterline, and it will carry a crew of 125. The boat will be powered by two 1,000-hp steam engines which will turn the boat's paddle wheel on the stern. Yes, it will have a steam calliope.
