The parts of the ship :ship:
The Bridge 🧭
The bridge is a room or platform of a ship from which the ship can be commanded.
During critical maneuvers the captain will be on the bridge, often supported by an officer of the watch, an able seaman on the wheel and sometimes a pilot, if required.
The Engine Room ⚙️
On a ship, the engine room (ER) is the compartment where the machinery for marine propulsion is located. To increase a vessel's safety and chances of surviving damage, the machinery necessary for the ship's operation may be segregated into various spaces.
The engine room is generally the largest physical compartment of the machinery space.
The engine room is usually located near the bottom, at the rear or aft end of the vessel, and comprises few compartments.
Passageways 🛗
a corridor on a ship.
Bulkheads
Types of Bulkheads:
On-tight or tank bulkheads: :check:
Form boundary of oil tanks. Are oil tight in nature & are tested for the same.
Non-watertight bulkheads: :check:
Are screens in accommodation and do not contribute to strength or water tightness. Used to subdivide compartment into smaller units of accommodation of stores Non-watertight Bulkheads.
Watertight bulkheads: :check:
These bulkheads are water tight and prevent flooding.
Deck
Tween deck
In a ship, the tween deck actually means an empty space separating or between (tween) two other decks in the hull of a vessel.
Flush deck
The deck that extends without any constructional breaks from the frontal part of the ship to the aft is referred to as the flush deck
Promenade deck
In a vessel, the promenade deck serves as a place for the voyagers to take a calming and enjoyable walk on the ship, while enjoying the beauty of the oceanic vista.
Weather Deck
A deck that is not roofed and thus is open to the ever-changing weather conditions of the sea is referred to as the weather deck.
Lower deck
The deck located below the primary or main deck is the lower deck.
Bridge deck
Bridge deck is the deck on which the navigational equipments of the ships are housed.
Upper deck
The deck that covers the hull of the vessel from its fore to its aft is the upper deck. It is the topmost deck on a ship.
Main deck
As the name suggests, the main deck is the primary deck in any vessel.
Quarter Deck
The deck located near to the chief mast of a vessel on its stern is referred to as the quarter deck. The quarter deck is a part of the upper deck and is inclusive of the poop deck
Poop deck
The poop deck is basically used by the vessel’s commanding superiors to observe the work and navigational proceedings.
The Superstructure 🛡️
A superstructure is an upward extension of an existing structure above a baseline.
This term is applied to various kinds of physical structures such as buildings, bridges, or ships having the degree of freedom zero
Ladders :warning:
A pilot ladder is a highly specialized form of rope ladder, typically used on board cargo vessels for the purposes of embarking and disembarking pilots.
Hatches 🚪
The various types of hatch covers that are mainly used on board are as follows –
Rolling type :large_blue_circle:
Rolling type hatch covers consists of two covers at the end of the hatchway. Wheels are fitted which help in the sliding of the panel either athwartship in case of side rolling or longitudinally in case of end rolling. These type of hatch covers are usually fitted on large ships. Hydraulic rams are required to raise them to rolling position as they are extremely heavy and have very large dimensions.
Folding type 🟠
Folding type hatch covers consists of two flat type topped panels which are operated via hydraulic arms. These may be fitted on both weather deck as well as tween deck. A major advantage in the design of folding type hatch covers is its large size which means less number of panels.
Lifting type :red_circle:
Lift away type hatch covers can be classified into two types
A) Single panel covers,
Single panel cover consists of a single cover for each opening, these can be seen mainly on bulk carriers.
B) Multi-panel covers.
In case of multi-panel covers, a single hold is covered via multiple numbers of covers, these are most commonly observed in cellular container ships in the case of longitudinal joints, and for multipurpose cargo ship in case of transverse joints.
Sliding type 🟣
The sliding hatch covers for tween decks can be fitted on both general cargo ships and in refrigerated cargo ships, especially where the decks are non-insulated. The panels slide, one under the other, as the hatch opens and they stow slightly sloping.
Roll stowing type 🟢
Fitted to general cargo vessels and small to medium bulk carrier weather decks.
The hatch cover consists of a number of panels spanning the hatchway, which are hinged at each of the cross joints.
This type is also popular on small general cargo vessels and inland waterway vessels.
The Hull :ship::
A hull is the watertight body of a ship or boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast.
