Cargo ships Containerships Bulk carriers without cranes: with length of around 140 m with length of around 250 m Crude oil tankers: with length of around 150 m with length of over 300 m

Henschke (1965) gives summary values for E&O weight on dry-cargo ships and coastal motor vessels:

VLR = hold volume [m3] VLR/Wdw = stowage coefficient [m3/t]

The formula is applicable in the range 1.2 < VLR/Wdw < 2.4.

The traditional statement that in dry-cargo ships the E&O weight roughly equals the weight of the engine plant, is no longer valid. The E&O weight is frequently 1.5-2 times that of the engine plant.

Reefers (between 90 m and 165 m in length)

Wo = 0.055L2 C 1.63V2/3 where L = Lpp and V; is the gross volume of insulated holds. The formula is based on the specifications of reefers built in the 1960s (Carreyette, 1978).
