Study Notes
Principal Structural Parts of a Ship
- Ships are large watercraft capable of navigating oceans and deep waterways, primarily for transportation of cargo or passengers.
- Ships are distinguished from boats by size, shape, load capacity, and purpose; they are essential for global commerce.
- As of 2016, over 49,000 merchant ships existed, with 28% being oil tankers, 43% bulk carriers, and 13% container ships.
Key Ship Dimensions
- LOA (Length Overall): The total length of the ship from the furthest point at the bow to the stern.
- LPP/LBP (Length Between Perpendiculars): Measured between the fore and aft perpendiculars, critical for stability assessments.
- Breadth: The width of the ship at its widest point, affecting stability and cargo capacity.
- Depth: Vertical measurement from the bottom of the keel to the top of the deck.
Types of Ships
- Container Ships: Specialized for carrying standardized cargo containers; dominate non-bulk cargo transport, handling around 90% of this traffic globally.
- Bulk Carriers: Designed for transporting bulk commodities like coal and grain.
- Tanker Ships: Primarily carry liquid cargo, such as oil and chemicals.
- General Cargo Ships: Versatile vessels for various types of cargo.
- Passenger Ships: Facilitate the transportation of individuals across water.
- Roll-on Roll-off (Ro-Ro): Allow vehicles and cargo to be driven on and off the ship.
Structural Members of a Ship
- Bridge: Command station for navigation and control of the vessel, housing navigational and communication equipment.
- Funnel (Stack): Chimney that expels exhaust from engines, designed to minimize pollution.
- Accommodation: Living quarters for crew, equipped with essential amenities such as galley, gym, and medical facilities.
- Flying Bridge: Elevated area offering unobstructed views for navigation; contains additional controls for maneuvering.
- Stem: Forward extension of the ship's hull, could be raked or plumb, affecting hydrodynamics.
- Forecastle: Functional area at the ship's bow, previously used for military purposes, now for anchoring and securing equipment.
- Foredeck: Area on the weather deck located forward of the mast; facilitates various ship operations.
Ship Features Enhancing Performance
- Bulbous Bow: Bulge at the bow to improve hydrodynamics, increasing fuel efficiency and stability by 12-15%.
- Stern: Rear part of the ship, crucial for propulsion efficiency; houses rudders and propellers.
- Poop Deck: Located at the stern, allowing the captain to oversee operations.
- Side Thrusters: Assists in maneuvering in tight spaces; can be hydraulically or electrically powered.
Propulsion and Steering Systems
- Rudder: Essential for steering, works by redirecting water flow; types include balanced, semi-balanced, and unbalanced.
- Propeller: Mechanism converting rotational energy into thrust; crucial for forward movement by pushing seawater backward.
