Before & After Hull Cleaning – Vessel In Tropical Waters

Fuel Savings % 4%

Vessel in Tropical Waters - Maximum Hull growth & loss of power Vessel in tropical waters and assuming that the marine growth & fouling would be maximum, hull cleaning resulted in a fuel saving of 6MT/day at 14 knots, 63% MCR on a fully loaded ship at similar weather conditions.

Before & After Hull Cleaning – Vessel in Cold Waters

Vessel in Cold Waters - Minimal hull growth & loss of power

Vessel in cold waters and assuming that the marine growth & hull fouling would be minimal, hull cleaning resulted in a fuel saving of 1MT/day at 14 knots, 70% MCR on a fully loaded ship at similar weather conditions.

Fuel Savings % 4%

Computation of Savings

Averaging the fuel savings in cold and tropical waters, about 3.5 MT/day [(6+1)/2] of fuel is saved – this is for a 50 MT/day vessel. With 280 sailing days a year = 3.5 MT x 280 days = 980 MT/year. Assuming fuel cost is US $250/MT, Annual fuel savings = US $ 245,000 Normalizing this data to make it uniform with a standard vessel consuming 75 MT/day (used for all other computations), savings will be US $367,500
