SNAME Los Angeles Section Discusses Use Of Concrete For Marine LNG Tankage
The members and guests of the Los Angeles Metropolitan Section of The Society of Naval Architects and Marine Engineers were welcomed aboard the S/S Princess Louise for their recent meeting. Bob Apple, chairman of the Section, opened the meeting and introduced the head table. John Hollett previewed the June field trip to Rockwell International for touring their ship propeller blade facility.
Mr. Hollett then introduced Abraham Person, author of the evening's paper titled "Qualification Program for the Use of Concrete for Marine LNG Tankage." Mr. Person is assistant chief engineer for Global Marine Development, Inc. of Newport Beach, Calif. The purpose of the Global Marine Program is to simplify the Marine LNG Containment System for Floating Offshore Facilities, and to reduce its cost. They have proposed to the United States Coast Guard a research and test program to qualify prestressed concrete as a secondary barrier. The USCG has accepted the program concept, and it is now in the financial development stage. The proposed use of prestressed concrete as a marine LNG secondary barrier, and the program to qualify this material to USCG requirements was the subject of Mr. Person's paper.
The program will integrate research, analysis and tests for meeting two objectives. First, to qualify prestressed concrete to USCG requirements for a marine LNG secondary barrier and second, to provide tools and data to design prestressed concrete materials for a marine LNG secondary barrier. The proposed tests include material property, quality assurance, and large and smallscale tests that are integrated to provide the necessary data for qualification of the material and for supplying design data. The program is expected to start sometime this year.
