The trim of a vessel impact the required force to propel a vessel through water, so for different loading conditions and sailing speeds there is an optimum trim. If the vessel is not sailing at or near the optimum trim then it experiences more resistance and will therefore consume more fuel. Vessel owners and operators use static trim tables as the predominant method of calculating the optimal trim of the vessel, however during transit it is hard to measure and monitor if this optimal trim is maintained.
WHAT WE CAN DO
With the use of a MRU that records actual heel, trim, roll & pitch, it is possible to determine the actual trim of a vessel at sea at any give time. A control PC with display and logging functionality continuously calculates the average heel and trim during a voyage. Variations in trim due to consumption of fuel/water/stores will become immediately visible. Re-distribution of ballast water will allow the crew to change the trim back to the optimum condition.
- Record and control the trim of your vessel during transit
- Keep your vessel at the optimum trim to increase fuel efficiency
- A learning curve to understand trim changes during sea-voyages can be used to optimize the loading conditions at departure
- A cost-effective way to reduce fuel consumption
