NASSCO is owned 50 percent each by Kaiser Industries Corporation and by Morrison-Knud- sen Company and is under the management direction of Kaiser Industries Corporation. The expansion will add a construction grav- ing dock of 160 feet by 1,000 feet, which will permit construction of vessels of 146 feet in beam and 956 feet in length—the equivalent of a 150,000-ton tanker or a 125,000-cubic-meter LNG vessel. Expected addition of 16 acres of leased land will permit construction of steel fabricating facilities to support fully construc- tion in the new dock, as well as on the three existing sliding ways. Cost of expansion, scheduled for completion in March, 1975, will be about $20 million. Nor- mal operations will continue during expansion. NASSCO is currently designing a 150,000- ton tanker which it believes will be an optimum design for the Alaskan oil trade. It expects to enter the market with the new design in mid- 1974 for deliveries by early 1978, when the Alaskan pipeline is expected to be completed. NASSCO has no current plans for LNG vessel construction. At December 31, 1973, the shipyard had on order thirteen 89,000-ton tankers, five 38,000- ton tankers, an 80,500-ton are/bulk/oil carrier, and one 37,000-ton Navy Oiler, representing a new construction backlog of approximately $500 million. Delivery commitments on all current back- log contracts are based on existing facilities. Delivery of six of the vessels currently in the backlog will be accelerated from four to ten months by constructing several of the 89,000- ton tankers in the new graving dock. 20 Maritime Reporter/Engineering News
