Study Notes
Multi-purpose Ships
- Versatile vessels capable of transporting diverse cargo types, including containers, bulk cargo, and breakbulk cargo.
- Equipped with specialized cargo handling gear to accommodate different cargo types.
Ship's Dimensions
- Length Overall (LOA): Total length from the foremost to aftmost points.
- Beam: Width of the ship at its widest point.
- Depth: Vertical distance from the keel's bottom to the main deck.
- Draft: Distance between the waterline and the keel, indicating how deep the ship sits in water.
- Freeboard: Distance from the waterline to the lowest point of the deck edge.
Ship's Principal Structure
- Keel: Backbone providing structural integrity, running from bow to stern.
-
Frames:
- Transverse Frame: Vertical ribs from keel to deck, enhancing hull shape and strength.
- Longitudinal Frame: Horizontal supports along the ship's length for added strength.
- Bulkheads: Vertical partitions enhancing rigidity and providing watertight integrity.
- Decks: Horizontal structures above the hull serving as floors, contributing to structural strength.
-
Hull Plating:
- Outer Plating: External shell offering watertight integrity.
- Inner Bottom Plating: Internal layer in double-bottom hull for safety and strength.
- Strakes: Longitudinal plating lines on the hull.
- Sheer Strake: Uppermost strake at the deck level for additional strength.
Collision and Longitudinal Bulkheads
- Collision Bulkhead: Located near the bow, prevents water ingress into main compartments during collisions.
- Longitudinal Bulkheads: Run lengthwise for strength, dividing hull into smaller compartments to improve stability.
Accommodation and Tank Bulkheads
- Accommodation Bulkheads: Separate living areas from workspaces, enhancing comfort and noise reduction.
- Tank Bulkheads: Enclose tanks for liquids like fuel or ballast, designed to withstand internal liquid pressure.
Seaworthiness
- Condition of a ship ensuring safe operation at sea, requiring:
- Structural Integrity: Hull and components must be defect-free.
- Equipment: Navigation and safety gear must function properly.
- Crew Competence: Adequately trained crew members.
- Maintenance: Regular inspections to maintain seaworthiness.
- Compliance: Adherence to international standards like SOLAS and MARPOL.
Seamanship
- Involves the skill and knowledge for effective ship operation, including:
- Navigation: Planning safe courses using navigational aids.
- Ship Handling: Maneuvering the vessel safely in various conditions.
- Safety Management: Implementing safety procedures and conducting drills.
- Communication: Effective interaction with the crew and external entities.
- Knowledge of Maritime Laws: Comprehending international regulations.
- Weather Awareness: Understanding weather impacts on navigation.
Plimsoll Mark
- Also known as the Load Line, indicating the maximum safe draft for loading a ship.
- Essential for maintaining stability and safety.
- Named after Samuel Plimsoll, an advocate for maritime safety in the 19th century.
Equipment and Safety Procedures
- Tools: Wrenches, screwdrivers, and other essential maintenance tools.
- Personal Protective Equipment (PPE): Includes hard hats, safety harnesses, gloves, and non-slip footwear.
-
Maintenance Procedure:
- Conduct safety briefings and inspect tools before use.
- Follow safety protocols during maintenance tasks.
- Document and report completed tasks and inspections.
Deck Equipment and Machinery Overview
Valves and Pumps
-
Valves: Control flow and pressure, prevent backflow.
- Types: Gate, Globe, Ball, Check, Butterfly valves.
-
Pumps: Move fluids throughout the vessel.
- Types: Centrifugal, Positive Displacement, Diaphragm, Submersible pumps.
- Safe Use: Inspect before operation, ensure proper settings, and follow manufacturer guidelines.
Lifting Gears
- Types: Cranes, Derricks, Davits, Winches.
- Facilitate safe lifting and lowering of heavy loads, enhancing operational efficiency.
- Inspect, train operators, and use appropriate signals during operations.
Deck Machineries
- Winches: Used for hauling ropes.
- Windlass: Primarily used for anchoring operations.
- Capstan: Vertical shaft for winding ropes and securing lines.
- Procedures include equipment inspection, clear areas during operation, and adherence to manufacturer guidelines.
Other Deck Equipment
- Hatches: Openings for cargo access.
- Watertight Doors: Prevent flooding between compartments.
- Port Holes: Small windows for visibility and light.
