NEW FLEXIBLE SHIPBUILDING AND SHIP REPAIR FACILITIES

Sun Shipyard was faced with the need of upgrading facilities to accommodate the potential for larger vessels--in particular tankers in the range of 100,000 to 400,000 DWT and also LNG ships of 125,000 cubic meter capacity. Certain "must" parameters for the facilities were established. These included (a) the facility must be flexible to cope with the unpredictable market and changing opportunities, (b) the facilities should be capable of constructing vessels of all sizes up to a 400,000 DWT tanker in a cost effective manner, (c) ships constructed at the yard should be able to be dry-docked at the yard and dry-docking should not be dependent on building schedules and occupany of the building location, (d) the facilities should include a pier parallel to the river for large vessels--constructed in a location so that minimum dredging would be required, and (e) the existing program of shipbuilding and ship repair should have minimum interference while new construction was underway. Facilities which has been newly constructed in both this country and abroad were examined in detail. None of the methods used are perhaps unique in themselves but the combination of various features provides a facility which meets fully the objectives. The facility is adaptable not only to the construction of ships but also for building other floating structures such as prestressed concrete caissons, offshore platforms, and other nonship structures. It is also suitable for putting ships on land for extensive underwater modifications where repairs can be made in a more efficient location. The complete facility was authorized in November 1973 and the first keel was laid in April 1975. The total cost of all the improvements including the floating dry dock was approximately $50,000,000. This paper describes in detail the Shore Facility and Transfer System, the Floating Dry Dock, and the 800 Ton Floating Crane.
