Report of Bollard Pull Tests for the Barge 'SEACON'

摘要

An experiment was conducted on the Naval Facilities Engineering Command's ocean construction barge 'SEACON' to measure the bollard pull generated by the barge's propulsive system in both the ahead direction and the athwartships direction. The experiment was conducted in Fort Lauderdale, Florida on 1 November 1979. This report documents the result of the experiment, and concludes that the barge develops approximately 15,250 pounds of bollard pull in the ahead direction, approximately 10,000 pounds in the athwartships direction, and, further, that the propulsion engines are developing close to their rated power when operating in the ahead mode. However, when thrusting laterally the reduced thrust noted is reflected in lower engine power output. Recommendations include a suggested modification to the stern lines to improve propulsive performance. (Author)
