A Guide to Vessels’ Engine and Engine Room

1. A Guide to Vessels’ Engine and Engine Room Vessels have various descriptions, types and have hundreds of thousands of components, but there are some crucial parts that are common to all vessels. In this write-up you are going to explore what comprises of an engine and engine room. People who are not directly associated with the functional and technical aspect of a ship, unlike marine engineer, there are possibility that they have never seen an engine room and do not have much detail about the engine parts. The engine room is an interesting zone and the heart of a ship. Evolutions of Vessels over Time Diesel engines and engine rooms for cruise ships or other marine vessels have changed to some extent over the decades. Currently, modern engines are designed to be more economical and release smaller amount of toxic exhaust gas fumes. Over the years, the main engines of the ships were causing a lot of air pollution. Due to this reason, the legislation has been brought in to cut down the exhaust gas emissions of vessels. Ship owners asked for improvements, and engineers and architects reacted by designing modern efficient vessel engines and engine rooms. These modifications started with the employment several methods in reducing the emissions. There are:

These are – top, middle and bottom. Along with loads of tanks and other paraphernalia, the top platform includes spare parts of the main engine, pumps, auxiliary machinery and operation of the vessel.

However, there are numerous equipments that are not located inside the engine room like winches, cranes and others. First, one should know where the engine room is situated.

There are no hard and fast rules about the placement of each parts of the equipment, but usually the cruise vessels for sale have engine room that has a number of levels comprising different machinery like auxiliary engines or diesel generators, the inert gas plant, fuel and oil pumps, a boiler, fresh water generator, the engine control room, purifiers, waste incinerator, storage tanks and multiple other paraphernalia such as electrical panels at different levels. ===================== NORWEGIAN SHIP SALES AS Raadmann Halmrasts Vei 18 1337 Sandvika, Norway Phone Numbers: +47 6754 1925 / + 47 9177 6183 Website: www.norshipsale.com Email ID: o.jebsen@norshipsale.no, info@norshipsale.no
