EEDI Verification


Verifying Energy Efficiency

At the initial/concept design stage, we provide the following support:

  1. As part of the EEDI preliminary verification, accurate estimates of EEDI can be provided accounting for the following design considerations:
    • Required value for type of ship, EEDI phase
    • Speed-power curve for specified EEDI loading condition
    • Main and auxiliary engine characteristics
    • Energy-saving equipment/devices
    • Fuel type
    • Ship’s cargo capacity (deadweight)
  2. Guidance in the following:
    • Planning of towing tank (model) tests to optimize the scope required to meet EEDI preliminary and final verification requirements including the use of energy-saving devices
    • The evaluation of tank test results for correlation with measurements from full-scale trials
  3. Assistance in meeting the IMO MEPC requirements for minimum propulsion power taking into consideration the constraints of the required EEDI values for the type of ship.  We provide both Level 1 and Level 2 assessments for bulk carriers and tankers

At the end of construction/sea trials and prior to delivery, we provide the following support:

  1. Guidance in the planning and conduct of speed trials required for EEDI verification as well as attendance on board.
  2. Independent speed trial analysis to confirm speed-power characteristics in calm water from which we derive the vessel’s EEDI reference speed.  We can also provide independent assessment of the vessel’s speed-power characteristics in specified contract conditions.
  3. Verification of the attained EEDI using the final (as-built) engine, vessel and speed-power characteristics.  As recognition of meeting the IMO MEPC requirements, we issue the IEE certificate.
