Additional aspects to be taken into consideration
The kind of propulsion system used on a ship also plays an important role in the design and construction of the ship. In the past, the ships had sails which used wind for the propulsion of the ship, but nowadays all ships are driven by a mechanical propulsion system. The driving power can be generated by diesel engine, steam turbine, gas turbine, or some form of fuel cells. Including the propulsion system, there are many other systems on board the ship for its efficient working and it is therefore important that the ship’s layout conciliates with the various systems.
One more thing that is taken into consideration for designing a ship is that not all the ports have the facility to accommodate all types and sizes of ships. This means that the geography and the depth of water at the port might abstain large ships from entering inside. Also, not all ports have the facilities for loading and discharging all types of cargo. For example, not all ports have the facility of gantry cranes for the loading and unloading of containers. This means that a container ship will never be sent to a port where there are no facilities of gantry cranes. This ensures that ships spend far less time in loading and unloading, cargoes remain more secure and most importantly port fees are reduced.
Thus naval architecture deals with the whole process of designing and construction of ship, keeping various aspects in mind. The sole purpose is to create the best possible ship to meet the operator’s needs by keeping the ship’s design flexible, safe and one which is able to adjust considerable level of risk. Naval architecture thus provides a foolproof design, taking all the possibilities into consideration to reduce the consequences of an unavoidable accident and keep the risk factor as low as possible.
Also, while architecting a ship, an important factor that is taken into consideration is the effects of dangerous and toxic cargoes in case there is an accidental spillage due to collision or human error. There are already stringent rules made pertaining to the adverse effects of toxic cargoes on environment that cannot be compromised and thus it’s absolutely necessary to abide by them and take them into consideration while designing and constructing a ship.
It is hoped that the previous paragraphs will provide the readers with a general overview of naval architecture as a disciplined and demanding engineering field.
