Facility Summary:

This inspection report was prepared as part of the Waterfront Facilities Inspection Program administered by the OC Ocean Facilities Division of the Naval Facilities Engineering Systems Command, Engineering and Expeditionary Warfare Center (NAVFAC EXWC).

Fuel Spill Response Storage The Fuel Spill Response Storage facility consists of concrete floating docks anchored in place by square concrete guide piles. The floating docks are accessible via an aluminum gangway from the Fuel Pier. The floats were installed in 1999

Fueling Pier The Fueling Pier is a concrete pile supported pier with concrete pile caps and deck beams with a concrete deck overlay. The pier was built in 1957 and is used to support fuel delivery operations and provides access to the Mooring Dolphins and Fuel Spill Response floating docks.

Facility Usage Description:

The Waterfront Fueling Pier is a concrete pier with concrete piles and batter piles supporting it.

It is accessible via a concrete walkway from the land behind it and supports a storage building as well as a guard tower. The purpose of the pier was originally to receive fuel shipments;

however it has been replaced by the outshore dolphin structure and now only provides access to the floating docks and mooring dolphins as well as providing support for the fuel lines running from the mooring dolphins to the inshore tank farms.

Facility Usage Description:

The Mooring Dolphin at Dock is used to receive fuel entering the base. Ships can moor up to the dolphin and pump fuel onto the base. The dolphin is comprised of four concrete platforms with concrete catwalks connecting them, supported by concrete piles. There is a steel fender system supporting the dolphin platforms. Outshore of platforms, there are four timber and four steel mooring dolphins. An access walkway connects the facility to the Fuel Pier behind it.
