Calculates Brake Specific Fuel Consumption (BSFC) or Specific Oil Fuel Consumption (SFOC) using a parabolic relationship with the main engine load factor.

calcLoadBSFC(loadFactor = NULL, BSFC_Baseline)

Arguments

loadFactor

Fraction of total installed propulsive power representing the instantaneous or average propulsive power (unitless) (vector of numericals) (see ShipPowerModel library). If NA is supplied, the baseline BSFC value is returned (i.e., the resulting emission factor will be independent of engine load).

BSFC_Baseline

Baseline BSFC value (g/kWh) (vector of numericals)

Value

BSFC (g/kWh) (vector of numericals)
