C-2 Major components. The workboat, lifesaving and firefighting system consists of a 23-foot, reinforced aluminum-
hulled, triple-V-bottomed craft, liferafts, lifevests, lifesaving ring buoys, a Halon 1301 system, CO2 hose reel units, a
smoke detector system, fire extinguishers, breathing apparatuses, and a portable firefighting pump. The major
components for this system are listed in CHAPTER 1. Also listed are basic functions and location on the barge for each

C-3 Workboat, lifesaving and firefighting equipment system description. This system provides water transportation
for crewmembers and visitors, small cargo, transporting the messenger line for shore discharge hose and similar work-
related tasks associated with operating the ROWPU barge in a safe manner.
C-3.1 Workboat is a 23-foot, reinforced aluminum-hulled, triple-V-bottomed craft with a forward cabin for six passengers
plus the operator and a flush after-deck for small cargo and messenger line reel unit. Closed cell flotation foam has been
used to fill the forward compartment, under the cabin floor, and small compartments on both sides of the engine
compartment. Workboat has two push knees on the bow, an aluminum tubular protective frame around the outboard
drive, and two bow and two stern mooring bitts. Workboat has a diving ladder that fits into sockets on either port or
starboard just aft of cabin and forward of aft guard rail. Lifesaving equipment includes eight lifevests stowed under cabin
benchseats and a ring lifebuoy with floating marker light and line.
C-3.2 Power is supplied by a six cylinder inline turbo-charged diesel engine, inboard/outboard configuration, driving a
single propeller. Engine revolutions per minute (rpms) and engagement are controlled by one lever at the operator's
station. Steering is by hydraulically operated controls at the operator's station. Complete instrumentation, including a 4-
inch compass and engine hour meter, is included at the operator's station. Workboat has two automatic bilge pumps, and
a 50-gallon diesel fuel tank in the engine compartment.
C-3.3 Workboat, when not in daily use, is stowed in its cradle on deckhouse top. It is held in place by three strap winches
on each side. These straps are hooked into three eyes on each side of boat just under the rubber bumper. The boat is
launched from storage using a three-point suspension harness attached to specially constructed points on the hull and
lifted overboard by a hydraulic bow crane and lowered into the water. The boat is lifted from the water and stored on the
cradle in the same manner.
C-3.4 Lifesaving Equipment, consists of 2 liferafts, 15 type II, and 24 type V lifevests and 4 lifesaving ring buoys. These
liferafts are designed primarily to protect personnel until rescue vessels arrive. They are equipped with two small paddles
for maneuvering only. Life buoys and lifevests are designed to sustain a conscious person in the water while awaiting
immediate rescue, not for moving any distance while in the water.
C-3.5 Barge firefighting equipment consists of Halon 1301 system, 2 CO2 hose reel units, a smoke detector system, 17
portable CO2 fire extinguishers, 5 dry chemical fire extinguishers, 5 self-contained breathing apparatuses, and a portable,
engine-driven firefighting pump. In addition, there is a 10-pound, portable, dry chemical fire extinguisher on the workboat.
