Datum Marine Shaft Power Meter

Product Description

Shaft Monitoring

Datum’s Marine Shaft Power Meter Systems are developed to provide real time and ongoing power monitoring data on propulsion shafts, thrusters and diesel generators.  These devices are commonly used for fuel economy monitoring and equipment maintenance planning programs and can be used in conjunction with our EEXI | ShaPoLi solution to keep vessel owners in line with the latest legislation.

The Energy Efficiency Design Index (EEDI) and the Ship Energy Efficiency Management Plan (SEEMP) requirements were made legally binding by the MARPOL Annex VI

Key Features

The technical requirements in this treaty are aimed at promoting the use of more energy efficient (less polluting) equipment and engines. In determining the best way to save fuel, we must initially understand how it is utilized and how efficient the vessel is, in converting the energy. A complex ship system will already provide much of the information required to ascertain fuel usage and maintenance of the vessel but a measurement of shaft power can show the efficiencies.

As a result, Marine Shaft Power Meter Systems were made to meet the requirements of the Commercial Marine customers to provide ongoing power monitoring data on ships. The current usage of the systems is to provide data for fuel economy and equipment maintenance planning programs. Fitted at an early stage the torsion meter system can be used in Ship Acceptance Trials and from that point on be a measure of the condition of the ship throughout its life cycle.
