040 INTRODUCTION AND GENERAL DESCRIPTION

040-1 Background

The Naval Facilities Command (NAVFAC) Oil Spill Response (OSR) Program is responsible for providing US Navy facilities with oil spill response equipment, including oil spill response boats.

OSR boats are centrally procured via the US Navy Boat and Craft Program Office, PEO SHIPS

(PMS 300G).

The mission of the 30OP Manned Advancing Skimmer boat is to provide OSR presence for US Navy Installations. Primary mission of 30OP is to remove light refined oils (i.e. Diesel Fuel Marine (DFM) and JP’s) from the water surface in harbors and protected waters. Working in conjunction with the other OSR boats and various boom arrangement schemes, the 30OP collects and transports the oil to an offload location. Typical mission duration is 3-8 hours, with operations during daylight hours, typically ending at dusk.

040-2 Definitions
