Appendix 1 - The Methodology for the Minimum Power Lines Assessment

 1 The minimum power line values of total installed MCR, in kW, for different types of ships should be calculated as follows:

  • where:

  • DWT is the deadweight of the ship in metric tons; and

    a and b are the parameters given in table 1 for tankers, bulk carriers and combination carriers.

Table 1: Parameters a and b for determination of the minimum power line values for the different ship types

Ship type a b
Bulk carrier which DWT is less than 145,000 0.0763 3374.3
Bulk carrier which DWT is 145,000 and over 0.0490 7329.0
Tanker 0.0652 5960.2
Combination carrier see tanker above

 2 The total installed MCR of all main propulsion engines should not be less than the minimum power line value, where MCR is the value specified on the EIAPP Certificate.
