Different Types of Ships its Parts and Characteristics of its Parts

1. Cargo Ships Cargo ships are generally used to transport cargo safely from one place to another. They will have a ship with a multi-deck or single-deck hull. There are thousands of cargo ships on the move around the world, transporting good across the globe. They are crucial to international trade. Cargo ships can transport things such as food, petroleum, furniture, metals, clothes and machinery.

2. RoRo (Roll on Roll Off) Most vehicles that are being transported over water internationally are done on a Roll on Roll off ship. The reason this ship is so popular to transport vehicles is that it’s safer and much faster to just drive a car onto the ship than using a crane. Once the cars are aboard, they are braced to the ship’s deck to keep them from moving around while the ship is at sea.

3. Tankers Tankers are ships that primarily carry huge quantities of liquid. They can carry a wide range of liquids such as oil, water, wine and lots of different chemicals that need transporting. They come in lots of different sizes but some of the larger vessels have the capacity to carry several hundred thousand tons.

DAVIT Winch that manipulates the anchors. RUDDER Submerged component that pivots on a vertical axle and is used to steer the boat. PROPELLER Device with blades integrated onto a shaft that is driven by the engine to provide thrust and thus impel the ship. RADAR MAST Mast with a radio-wave detection device (radar set) used to prevent collisions when visibility is reduced. GUARDRAIL Railing along a ship’s deck that protects crew from falling overboard. SEPARATOR Device that removes any water that might contaminate the oil tanks. RADIO ANTENNA Metal conductor that emits and receives radio waves for communications. MOORING WINCH Motorized spool around which a mooring cable is wound. CROSSOVER CARGO DECK LINE Thick pipe that runs transversally and is used to fill and empty the tanks. BITT Metal cylindrical fittings attached to the deck for fastening mooring ropes and tow lines. AIR RELIEF VALVE Device that allows air to escape as oil fills the tanks to displace it.

TANK HATCH COVER Watertight door that provides access to a tank. FOREMAST Mast located near the bow of the deck that supports the navigation lights. MAIN DECK Flat top that seals the hull and protects the cargo; it provides space for crew to circulate and for auxiliary equipment. WALL SIDE Vertical part of the hull below the water line. FOAM MONITOR Pressurized mechanism that produces foam for extinguishing fires. DERRICK MAST Short thick mast that supports the derrick. DERRICK Device with pulleys that is mounted on a pivot for handling loads. BULB Bulge in the bottom part of the stem that reduces the hull’s water resistance. TRANSVERSE BULKHEAD Wall that divides the hold across the width thus demarcating the tanks. LENGTHWISE BULKHEAD Wall that divides the hold along the length to demarcate the tanks. ENGINE CONTROL ROOM Compartment housing the instruments that monitor the ship’s movement and control the engines and other machinery. PUMP ROOM Compartment housing the machinery that pumps the oil in and out of the tanks. CENTER KEELSON Metal girder that runs along the ship’s longitudinal axis to reinforce the bottom of the hull. WEB FRAME Metal reinforcement that spans the hull transversally. TANK Watertight reservoir; the hold is divided into several tanks to prevent sloshing.

4. Passenger Ships Passenger ships are officially defined as ships that carry more than 12 passengers. If you own a passenger ship then you will need to abide by strict safety regulations. There have been several disasters with passenger ships lately so the rules and regulations

have been updated in a bid to try and improve safety. Passengers should be able to travel in a safe and comfortable environment. Passenger ships also include cruise and holiday ships.

5. Fishing Vessel Fishing vessels are boats and ships designed to catch fish and marine wildlife. They are used for leisure purposes but also for commercial fishing. There are millions of fishing vessels being used to catch fish around the world. If you are considering working on a fishing vessel then it is important to know that they are very dangerous. According to the International Maritime Organisation (IMO) there are around 24,000 deaths on fishing vessels each year. All ships engaged in international voyages must install an ECDIS. Electronic chart display and information systems can help fisherman avoid bad weather and navigate through international seas. 6. High Speed Craft High speed crafts are also sometimes called ‘fast ferries’. They are mainly designed for civilian use as passenger ferries. They also include hovercrafts, catamarans and hydrofoil boats. High speed crafts are able to go faster because they use air pressure and powerful turbine propellers....
