Remark Large tankers and large bulk carriers is easier to arrange auxiliary machinery in the engine room because of the enlarged hull form, compared to other types of vessels. For tower placement, it is necessary to devise if the casing is narrow. In case of ULCS, the size of the scrubber tower becomes large because the output of the main engine is large, so arrangement whitch minimizes the cargo loss is required. For medium and small sized ships, generally there is only a little space, so arrangement of devices such as seawater pumps and auxiliary equipment and scrubber tower need to be devised. In case of large sized PCTCs, an arrangement with a reduced height is required because funnnel height is close to the airdraft limit.
