McNab, Inc., Mount Vernon, N.Y., has just introduced a computerized fuel management system as an answer to skyrocketing fuel costs. The McNab 63000 onboard system automatically receives instantaneous operating data on shaft horsepower and ship's speed. It calculates fuel consumption costs from these and other parameters, and utilizes fixed costs of the voyage and revenue from the voyage to give a continuously up-dated display of profit in dollars and in percent at various speeds in knots. Immediate decisions can be made from this data concerning the most economical steaming speed.
Each 63000 system is programmed by McNab for the ship's specific characteristics, such as draft forward and aft. The system is applicable to either diesel or steam-powered vessels. It comes self-contained with its own computer, or can use a ship's present onboard computer.
According to McNab, the 63000 fuel management system can pay for itself in as little as 90 days in fuel cost savings.
