McNab Model 63000 Fuel Management System

Soaring fuel costs are becoming a terrible burden to the shipping industry. Unfortunately, you have to live with with this situation, but at least you try to make it hurt less. Why not consider turning to our Fuel Management System (FMS) for help.

In a nutshell, FMS makes available for the first time, a display of SPEED vs. PROFIT, on a per voyage basis for your particular ship. This table helps you set the best speed and make the best decision between profit and scheduling, or other conflicting needs.

Your vessel's characteristics, and hence its optimum speed were set by someone at least five years ago. Years have gone by and fuel costs have increased ten-fold. Certainly, a review of optimum speed is indicated. This is what the FMS does.

Our System learns the specific characteristics of each ship, employing our well established electronic sensors combined with data that this is the most sophisticated, practical fuel management system now available.

Shoreside Data


Yearly fixed costs, those deemed to remain constant, are known and easily available.  These costs include all charges such as insurance, crew cost, etc.  but not fuel.  Line 27 of the Federal Income Tax Form 1120 from prior year's operation, allocated per ship with forecast adjustment will give you a very close approximation of ship's fixed costs.


Data such as voyage inbound, voyage outbound and planned in-port time, etc.

Shipboard Instrumentation

Shaft Alley

Accurate data on real time shaft torque, RPM and speed.

Shipboard Data

Chief Engineer

Heavy displacement, light displacement, voyage displacement, speed factor, fuel factor, speed slippage factor, load weight factor, hotel services, and other engineering log data.


Voyage distance, chart current.

Bridge Control Display

Data from shore, ship and sensors is continuously analyzed by the intelligent terminal and then displayed as the speed versus profit.

System Highlights

For the Owner/Operator
  • Simulation modeling of ship operation and testing of alternate strategies to determine the best option for your ship.
  • Derivation of system based on generally accepted accounting principles of break-even cost analysis (based on application of cost to speed/power curve)
  • Options include cost and speed analysis for the following changes:
- Hull fouling
- Excessive in-port times
- Diesel conversion
- Fuel cost
- Freight rate
- Routing (distance & current)
  • One year warranty coverage.
For the Shipboard Operator
  • Only 30 entries required, once per voyage.
  • Ongoing inputs are provided automatically during at sea operation.
  • All data easily entered within 5 minutes at pierside (special typing skills not required)
  • Simple step-by-step data entry instructions in standard marine terminology (no need to know computer languages)
  • Results are displayed in simple table of speed vs. profit in one knot increments (expanded scale down to one-tenth knot).
  • Optional security system prevents tampering and unauthorized use.
For the Installer
  • Installation time approximately 12 hours without need to disturb shipping cycle.
  • Shaft horsepower zero and full scale calibration completed pierside (a unique feature).
  • Requires no extensive platform building, no hull penetration, no shaft modifications, no repiping (all components) typically pass through existing hatchways and passages).
  • Applicable to diesel, steam, or coal.
  • Critical verification of calibration via built-in mechanical test set.
  • Sensors installation has been granted US Coast Guard approval.
For Service Personnel
  • Off the shelf parts availability direct from McNab.
  • Anticipated maintenance less than one day per year, skill level required - Ship's Electrician.
  • Built-in trouble shooting guide.
  • FMS downtime does not affect ship operation.
