This Scope of Work (SOW) outlines the requirements for a contractor to perform repairs on the U.S. Coast Guard Station Coos Bay's 47' Motor Life Boat (MLB) Class C 47302. The project involves cropping and renewing sections of the Port and Starboard Rudder Stock Housing Assemblies according to Coast Guard drawings and technical publications. Key tasks include hauling out the vessel, removing rudders and interferences, gas freeing the lazarette, cropping and renewing specific components, conducting visual inspections and non-destructive testing of welds, and finally re-installing rudders and interferences before a full power trial. The contractor must commence work within 15 days of acceptance and complete it within 28 working days from the scheduled haul-out. The SOW also details conditions for additional work, notification procedures, workmanship standards, permit requirements, clean-up, and points of contact.
