Service Life Extension Program (SLEP)

A SLEP is a major overhaul intended to extend a vessel's service life; it is typically scheduled as the vessel approaches the end of its originally planned service life. The Bay-class tugboat SLEP project includes significant system upgrades and improvements to the propulsion plant; to the heating, ventilation, and air conditioning systems; installation of an engine-room fire-suppression system; boat launching davit replacement; Oily Water Separator replacement; stack exhaust configuration modifications; hull air-ice lubrication system; and crew habitability improvements to meet current standards (including removal of lead paint).
