Study Notes
Introduction to Marine Vessels
- Module focuses on fisheries engineering
- Learning outcomes aim to explain details and parts of vessels, and to classify types of marine and fishing vessels.
Directions/Parts of a Ship
- Four fundamental directions are used with respect to the waterplane section:
- Waterplane Section
- Transverse Plane Section
- Middle Line Plane Section
- 6 main directions in the transverse plane section are:
- Hull: Main body including sides and bottom
- Gunwale: Sides of the ship
- Keel: Ship's backbone, lowest part, provides strength and stability
- Beam: Widest part of the ship
- Freeboard: Distance between gunwale and waterline
- Draft: Distance between waterline and keel
- Other directions include:
- Amidships: Central part between stern and bow, inline with the keel
- Athwartships: Towards the sides of the ship
- Forward: Towards the bow direction
- Aft: Towards the stern direction
- Inboard: Part of the ship attached inside
- Outboard: Part of the ship attached outside
Parts of a Fishing Vessel
- Rudder: Controls left/right movement. Located near the stern.
- Propeller: Creates forward movement. Radiating blade.
- Engine Room: Houses propulsion machinery.
- Main Engine: Powers ship's propeller through water movement.
- Fuel Tanks: Store fuel for the main engine.
- Starboard Bracket Pole: Used for nets and otter boards/trawling.
- Net Drum: Deploys/hauls net fishing gears.
- Funnel: Excels steam and smoke from boilers and engine exhaust.
- Mess Room/Hall: Dining.
- Bridge: Commanded area with navigational equipment and control panels for main engine.
- Cabin: Area for crew sleeping.
- Bulwark: Prevents equipment and crew from falling into the sea.
- Scupper Hole: Drains deck water.
- Hatch on fish tank: Entrance/exit for fish caught.
- Drop chute: Narrow tube connecting hatch and fish tank.
- Fish tank: Fish storage. Insulating layer to protect from temperature changes.
- Bilge keel: Prevents ship from rolling (roll axis).
- Bow thruster installation: Propulsion system attached to the vessel's bow.
- Name of ship: Registration number.
- Fishing winch: Mechanically reels in/out ropes, wires/cables.
- Conveyor belt: Transports caught fish to a horizontal direction.
- Guide pullies: Supports movement and redirects fishing lines/tension.
- Forecastle deck: Upper deck near the bow.
- Power block: Mechanized pulley to haul nets.
- Fishing Derrick: Crane-like structure for lifting fishing nets.
- Mast: Supports derrick and power block, located at the center.
- Radar antenna: Detects ships and landmasses.
Types of Marine Vessels
-
Transport vessels: cargo, container, and passenger ships
-
Non-transport vessels: fishing vessels, service craft, supply vessels, warships
-
Other types include various specialized vessels (high-speed crafts, catamarans, hydrofoils, small waterplane area twin hulls (SWATH), hovercrafts, merchant ships, roll-on roll-off (RO-RO) ships, tankers, passenger ships, ferries, tugs)
Common Parts of Fishing Vessel
- Stem
- Frames
- Dugout
- Hull
- Stern Post
Common Fishing Vessel Designs (PH)
- Typical Spoon Type Design
- Rake Stem - Rake Stern Design
- Plumb (Modified "Limasawa" Type)
- Skiff Boat (Service Boat)
Types of Bottom Trawlers
- Otter trawler
- Beam trawler
- Demersal seine trawls
- Scallop dredges
Purse Seiners
- Uses purse seines to surround fish shoals.
Longliners
- Carry either pelagic or demersal longlines.
Gillnetters
- Deploy or tow gillnets.
Additional Information About Fishing Vessels
- Designs are specific to local conditions and fishing methods.
- Classified according to fishing equipment/methods (trawlers, seiners, dredgers, longliners, etc.)
- Gross tonnage is used to classify these vessels into classes such as municipal or commercial.
