IMPROVED DESIGN OF LARGE ALL-AFT CARGO SHIP MACHINERY AND ACCOMMODATION
From the earliest days of steam propulsion custom placed crew accommodations and navigating bridge over the engine room, the only positions which did not obstruct cargo hatches. Except in oil tankers, engines and accommodation were placed amidships, with funnel and access casings passing through the superstructure. Motor ships followed the same pattern until recently, when engines, accommodation and navigating bridge were moved aft, as was the practice in oil tankers. In early steam and motor ships, engine noise and vibration was not serious in relation to crews' quarters, but the recent rapid development of large, highly rated diesel engines used in large, high powered ships, all the crew accommodation aft and above the engines, engine and propeller noise and vibration inflict an intolerable discomfort on the crew. The paper submits that machinery and its layout must be arranged to eliminate, as far as possible, all noise source and so isolate it from living quarters as to ensure peace and quite for those living aboard, even if this means some sacrifice of maximum engine economy and optimum cargo facilities. To achieve this, plans for machinery layout and crew accommodation must be drawn up together with the accent in favour of crew comfort. Such typical plans and guide lines are given in the paper.
