The San Diego Section of The Society of Naval Architects and Marine Engineers opened its 1978- 79 program year by holding its September meeting at Caesar's Mission Valley, San Diego, Calif. Benjamin V. Andrews, maritime consultant, presented a compre- hensive paper entitled "Heavy Lift Ship Design and Costs." The paper covered the types of ships capable of carrying heavy lift cargo, which is defined as (1) a single unit of cargo in ex- cess of 100 tons weight, or (2) a single unit of cargo exceeding a length of 80 feet or a width ex- ceeding 15 feet. The author next described a series of parametric ship designs and costs that in- cluded a range of ship and barge sizes for the three basic methods of heavy lift cargo handling, lift, roll and float. The paper concluded with the problems that American- flag heavy lift vessels will have to overcome in order to be cost competitive. The members and guests in at- tendance concluded the meeting with a question and discussion period. The Gulf King 12 is powered by a Kelvin at 415 shp.
