a. The barge hull is divided into six compartments with a combined capacity of 4,495 barrels of liquid cargo. A
diesel engine driven cargo pump is provided to unload the liquid cargo. Piping and valve arrangements are designed to
facilitate loading and unloading of individual compartments.
b. The diesel engine drives the cargo pump through a right angle drive speed reduction gear system. The engine is
started with a hydraulic cranking motor.
c. Fuel reaches the engine from a fuel tank secured on top of the machinery house which shelters the engine.
Engine cooling is accomplished using fresh water circulated through a fan cooled radiator. There is a remote manual
auxiliary shut-down device in the event of an emergency.
d. The barge is equipped with two 300 pound anchors which normally are secured on the main deck forward. A
single davit, a roller chock, a hand operated windlass, and various lengths of line for handling the anchors are provided.
e. Bilge must be removed from the compartments at intervals depending on circumstances. Two hand operated
bilge pumps are located on the main deck for this purpose.
f. Battery operated running and navigational lights are installed on the barge for towing operations. While under
tow, it is the responsibility of the tug boat captain to see that proper navigation signals are displayed and proper sound
signals are given.
