Abstract:

Two feasibility studies were conducted to utilize the existing jack-up barge, SIR ROBERT, for use in Project METEOR. One of the studies was to install the SIR ROBERT as a fixed gravity platform offshore Thousand Sprints Cove of the northwestern end of San Nicolas Island, California. The other study was the conversion of the SIR ROBERT to a wheeled amphibious platform four use in a flat sand beach. Two of the concepts were feasible in terms of structural modifications. However, safe operation of the modified SIR ROBERT is strongly site dependent. Included in the studies were the project planning, scheduling, and cost estimate. Both Navy Organizations and commerical contractors were contacted for their availability and estimated cost for participations. The estimated project cost ranged from 151,570 to 337,880 for fixed gravity platform and was 275,600 for wheeled amphibious platform. The varaition of project cost for fixed gravity platform is mainly due to site foundation conditions. Based on the available soil information supplied by the sponsor, studies on foundation stability, scour protection and wheel system trafficability were performed in conjunction with the feasibility study. Favorable results were reported.
