What Are The Different Parts Of A Ship And Their Meanings?

Today we are going to talk about Parts of a Ship. All of these ships include both visible and invisible parts. Rudder, anchor, bow, keel, accommodation, propeller, mast, bridge, hatch cover and bow thrusters are some of the common visible parts in this ship and while bulkheads, frames, cargo holds, hopper tank, double bottom, girders, cofferdams, side shell Etc. So let us gather a little more information about Parts of a Ship and their meanings.

The part called forecastle is located on the bow of the vessel to secure the docking process. This part is also useful for the accommodation of sailors on the ship. Forecastle is known as one of the main parts of the length ship which is found to be less than 7% of the total deck length. Forecastle was initially used in military vehicles and in which soldiers used prognosis to take a defensive position. This part performs many functions such as holding, anchoring and securing the main parts of the ship.

2. Main Deck

Main Deck

This part is known as the main deck of the whistle. This part is on the ship that comes in maximum exposure to the weather. This part is the topmost deck of the area from the bow to the stern on the vessel. The hull of a steel ship can be considered a structural beam in which the main deck forms the upper flange of the box girder. This part can act as a stress member on the ship when the ship is supported by a wave amidships.

3. Portside and Starboard Side

Portside and Starboard Side

Portside and Starboard Side is a space on the left side of the vessel. Portside Starboard Side is usually provided on the port side only. Part of the ship definitely refers to the left and right side of the ship. The portside of the vessel always refers to the same part of the ship's structure and does not depend on what the observer is facing. Orders and information can be clearly given through this part without the need for any member to know how to deal with it.

4. Rudder


The ship is operated by a part called Rudder. Without this part you cannot move the vessel in the desired direction. Rudder propels the propeller ship and drives the shaking ship. This part is a flat hollow structure and is placed on the back of the propeller. There are three types of rudder: balanced type, semi-balanced type and unbalanced type. This part is a primary control surface. In larger ships, cables, pushrods or hydraulics can be used to link this type of part to the steering wheels.

5. Super Structure

Super Structure

This type of part on the ship is an extension of the existing structure above the main deck. The term Super Structure applies to buildings, bridges, or ships with a degree of zero freedom. Super Structure is a project above the main deck of the ship. The Super Structure usually does not include its masts or any weapon constructions. The size of this type of part can have many effects on the operation of the vessel as the structures of the Super Structure can change their structural rigidity, their displacement and stability.

6. Bottom


The bottom is known as the lowest part of the hull of the vessel. Part of this type of ship is the design and construction method where the bottom of the vessel consists of two complete layers of watertight hull surface, one of which forms the normal hull of the ship and the other the inner hull which is slightly higher in the vessel which damages the outer hull and In case of leaks it creates a useless barrier to seawater.

7. Bow Thruster

Bow Thruster

This part of the ship is a transverse propulsion device. A bow thruster is built into the bow of a vessel or mounted on it. This part is also known as Manoeuvring thruster. Bow Thrusters make docking on ships easier because they allow the captain to turn the vessel toward the port without using the main propulsion mechanism. The effectiveness of Bow Thruster can be reduced by any forward motion.

8. Bridge


The ship's bridge is called the room or commanding platform. Ships can be ordered from the bridge. This bridge is managed by a clock officer when a ship is on and usually serves as a competent sea lookout.

The bridge controls the ship's vital deck machinery, the main engine and the ship's navigation system. Generally the function of the bridge is to monitor the weather and sea conditions on the ship and to navigate and fix the position of the vessel and to facilitate internal as well as external communication.

9. Bulbous


A bulbous bow is a bulb protruding towards the front of the vessel below the waterline. Bulbous improves the flow of water around the hull on the ship and reduces strain. Bulbous increases speed, range, fuel efficiency and stability in a ship. High-speed ships that are proportional to the square of mass and velocity and have the advantage of having a bulbous bow of this type designed for their operating speed.

This type of vessel usually has 12-15% better fuel efficiency compared to similar vessels without them. Bulbous also increases the rigidity of the front of the ship and therefore reduces the pitching of the vessel to a lesser extent. The length of the water with bulbous on the vessel is about 15 m longer. The design of this type of part is optimized for the operating speed of the ship.

10. Crane


A crane is a part used to unload, load, and unload cargo from and above a vessel. Crane on a ship is electrically or hydraulically operated devices for easy operation. The capacity of this type of part and gears for handling cargoes is 15 tons to 4000 tons per hour. The position of the crane on the ship is fixed and cannot be rotated and so it is drilled to place the loads on the ship.

11. Funnel


Funnel is known as Stacks. The funnel is a chimney on the vessel used to discharge smoke from its engine and boiler across the ship. This part on the vessel is the lifting of the exhaust gas, clear from the deck, the constitutional purpose of the funnel. Extra care has now been taken in dissolving the shoot from this part to protect the environment from pollution. This part in the vessel also served to help induce convection draft by boilers.

12. Hull


The hull is known as the watertight body of a ship. This part may open at the top of the ship or this part may be fully or partially covered with a deck. Hull can be a deckhouse and other superstructures at the top of the deck, such as a funnel, derrick or mast. The hull is the line where the ship meets the surface of the water called the waterline. Currently the most commonly used form on a vessel is the round bilge hull.

13. Tween Deck

Tween Deck

This part of the ship is sometimes referred to as three-deck normal cargo. The lower deck onboard refers to the deck of this deck. The Tween Deck is called the weather deck. Cargo, such as bales, bags or drums, can be placed in the space of a tween deck on top of this deck. Below this part of the ship is the hold space used for normal cargo. Freight ships by Tween Deck have standard shipping containers and fittings for retractability.

14. Bulkhead


This part is known as the straight wall inside the hull of the ship. Bulkhead other types of partition elements inside a ship are decks and deck heads. This part on the ship can increase the structural rigidity of the vessel. The bulkhead divides the functional areas of the vessel into rooms and may contain water in case of other leaks. This part on the ship is the decks are the fire-resistance that is rated to achieve compartmentalization and which is the passive fire protection step.

15. Holds


There is a part on the ship called Holds where the goods are transported. Holds can be packed in crates, bales etc. The access to this part of the ship is by a huge hatch at the top. An alternative way of carrying in the holds is in a standard shipping container that can be properly loaded into this part. Holds on the ship can load and unload their own goods.

16. Waterline


The hull of the vessel meets the surface of the water through the waterline. The Waterline on the ship is also the name of a special mark known as the International Load Line, Plimsoll line and Water Line. The waterline indicates the draft of the ship and the legal limits at which a ship can be loaded. The purpose of this part is to ensure that there is sufficient freeboard in the ship and thus to ensure adequate reserve boom.
