Basic Ship Types, Characteristics and related hazards

A ship is a huge vessel which moves within the water; they are of two main categories, namely; the modern ships and the ancient ships. Both the two categories get their power to sail on water from the wind energy. The traditional types are often fixed with masts which contain a number of sails fixed on each of the masts. They can be referred to as very complex vehicles which are very large; they usually have long time sustainability in their environments, they must also be very reliable to degrees of high levels within their environments (Martin, 1980). Initially before the invention of the ship, boat had been in use for very many centuries. The invention of the first ship was during the 3000 B.C., these were the ancient war ships and the vessels which were used by the merchants; these vessels were distinctively designed as they served different purposes; the warships were majorly designed for launching attacks, raiding and defending various territories while on the other hand, the merchant ships were designed for the purposes of transportation, they were used for transporting cargo. During this era, the constructions of the ship were done from various materials and in different shapes and sizes (Zanic et al, 2005). The ship is a combination of three major skillful areas namely; the naval architect skills, the skills of the officer in charge of navigation and lastly the skills of the engineering officer or the marine engineer. The naval architectural skills is the one which is concerned with the ship itself, its construction and the capability of the ship to provide the type of endurance which is required by its environment. The second skill is the one possessed by the navigation officer who is charged with the responsibility that the ship sails smoothly and safely, and that its contents; humans and the cargo be safely navigated to their destinations (Martin, 1980). The engineer in charge of the marine is the skill which is needed for the operation and the propulsion of the ship through the water; basically, it is the most complex machinery on the ground to make sure that the sheep is well steered, the ship anchors as expected; the skills should also ensure that the ship is steered safely and secure; the power generation and distribution of this device is also checked by these skills. A ship comprises of two major parts; the mechanical part and the hull. The hull is the general shell that composes the ship with the superstructure inclusive; the mechanical part is the main engine which is responsible for driving the ship, it also includes other parts such as the auxiliary machinery which include the generators and the boilers; this part is the one that is responsible for the purposes of maneuvering the ship, steering the ship, taking care and handling the cargo and also for many other purposes and services; the electrical installations, the plants of the refrigeration’s and the winches. The hind back of the ship is known as the stern or the end; when the ship moves with the stern in front then it is said to be moving astern. The front part of the ship is termed to as the fore extreme, therefore when the ship moves with the front part ahead it is referred to as a bow; the vessel moves ahead when the bow is in front. The fore and the after and are applied generally when referring to directional purposes. The part of the ship which appears at the middle, that is between the after and the fore is called the amidships. Finally, the longest breadth of the ship which is found within the amidships body is termed to as the beam (Martin, 1980). As time went by, the purposes for which the ship was designed changed the materials which were used in their construction, the physical appearance of these ships and also the methods which were used in their propulsion. For example, the merchant ships have to be larger compared to the...
