Chemical Tankers

The structural configuration and arrangements of chemical tankers often are basically similar to those described for oil tankers. For some chemical tankers, however, arrangements may also include a double bottom in way of cargo tanks, a double skin construction or deck cofferdams or any combination of these. Certain more hazardous cargoes may also require tanks which are separate from the hull structure or are to be so installed that the tank structure is not subject to major hull stresses. In the latter cases the scantlings and arrangements may be similar to ships carrying liquefied gases.
