This test plan was developed to demonstrate the feasibility of using an alternative fuel in USCG diesel-powered boats. A blend of 100 biodiesel B100 was selected as the test fuel and a USCG 49 Buoy Utility Stern Loading BUSL boat with Cummins main diesel engines and generator was chosen as the demonstration boat. Testing consists of four phases materials, bench, field, and operational testing. Materials testing will ensure all components in the engine and fuel system are compatible with B100. Bench testing will ensure the engines operate satisfactorily on B100. Field testing will ensure there are no problems with using B100 on the USCG boat prior to operational testing. Operational testing will ensure there are no problems with using B100 on the test boat over an extended period that encompasses typical operational and environmental factors including cold weather operations. This test plan describes the procedures for the field and operational testing. Prior to commencing field testing, the BUSL engines and fuel systems will be modified in accordance with a Time Compliance Technical Order TCTO to ensure compatibility with B100.
