Twin City Shipyard Delivers

Split Hull Barges To Panama

Split hull hopper barge built by Twin City Shipyard can be ac- tivated by radio control.

Two split hull hopper barges were recently delivered to the Panama Canal Commission by Twin City Shipyard, Inc., St. Paul, Minn.

The two ruggedly constructed dump barges were specially designed by Twin City Ship- yard for the Panama Canal Commission to handle extremely large and dense blasted rock up to 10 feet in diameter having a loaded specific gravity of 2.26.

Special features include hopper sheathing over the steel plate sloping sides of 3-inch white oak planking and 1-inch steel rein- forced rubber. Double course hopper seals are of special rubber moldings developed by TCS engineers. TCS utilized its patented hull lock- ing device along with TCS's improved hull ac- tuating system. The critical alignment of the two hull halves was maintained by a carefully controlled welding sequence during construc- tion. Two machinery rooms are provided be- low deck, one housing a diesel generator set and switch gear and the other containing the hydraulic power unit for the two opening and closing rams. Each machinery space has an independent fixed C02 fire extinguishing sys- tem. Two bilge pumps are piped into recessed hydrants for deck washdown. The opening and closing of the hull can be totally controlled at a deck mounted console or from a hand held radio controlled station from a distance of up to V4 mile. Slow-speed and high-speed hull opening and closing functions are provided.

The dump barges are designed and built to

ABS classification and U.S.C.G. certification for full ocean service.

Daewoo Employs Unique Floating

Drydock And Ship Transfer System

This floating drydock at Daewoo's Okpo yard employs a Hy- dranautics Hydraulic Systems innovative ship transfer system.

A new floating drydock and innovative transfer system were commissioned recently in the Daewoo shipyard at Okpo, South Korea.

The drydock, designed by U.K.-based A.P.

Appledore, features four fixed towers which serve as wing walls, differing from the tradi- tional concept with full-length wing walls.

The transfer system supplied by Hydranau- tics Hydraulic Systems, Goleta, Calif., also represents a new generation in shipyard de- sign and operation by providing virtually un- limited flexibility, according to John John- son, Hydranautics Director of Shipyard

Systems.

Capable of moving ships or ship sections up to 6,000 metric tons, the Hydranautics system will be used to transfer ships or ship sections on or off the floating drydock. In the yard, ves- sels can be moved by the hydraulic system on fixed or portable beams.

Additional versatility has been provided by the Daewoo yard since the Hydranautics hy- draulic system can accommodate movement of offshore structures and jack-ups as well as ships.
