B. Ferries
📌 Function: Short-distance transportation of passengers and vehicles.
📌 Types:
- Ro-Ro Ferries (Roll-on/Roll-off) – Carry cars and trucks.
- Hydrofoil Ferries – High-speed passenger transport.
4. Offshore Support Vessels (OSVs) ⚓
These vessels support offshore oil & gas platforms.
A. Crew Boats
📌 Function: Transport personnel & supplies to offshore oil rigs.
📌 Feature: High-speed vessels, 30-60 meters long.
B. Platform Supply Vessels (PSV)
📌 Function: Transport fuel, drilling fluids, and equipment to oil platforms.
C. Anchor Handling Tug Supply (AHTS) Vessels
📌 Function: Handle anchors and tow oil rigs in offshore drilling operations.
D. Diving Support Vessels (DSV)
📌 Function: Support underwater construction and maintenance.
E. Seismic Survey Vessels
📌 Function: Conduct ocean floor mapping and oil exploration.
5. Tugboats & Workboats 🚢
These small but powerful vessels assist in maneuvering and towing other ships.
A. Tugboats
📌 Function: Assist large vessels in docking, undocking, and navigation in harbors.
📌 Types:
- Harbor Tugs – Assist ships in ports.
- Ocean Tugs – Tow large ships across long distances.
B. Multicat Workboats
📌 Function: Multipurpose workboats used for towing, lifting, and dredging support.
C. Push Boats (Pusher Tugs)
📌 Function: Push barges on rivers and canals.
6. Fishing Vessels 🎣
These ships are used for commercial fishing and seafood harvesting.
A. Trawlers
📌 Function: Use large nets to catch fish.
📌 Types:
- Bottom Trawlers – Drag nets on the ocean floor.
- Midwater Trawlers – Operate nets in mid-depths.
B. Longliners
📌 Function: Use long fishing lines with baited hooks.
C. Purse Seiners
📌 Function: Use large nets that close like a purse around schools of fish.
7. Military & Defense Ships 🚢
These vessels are operated by navies and coast guards.
A. Aircraft Carriers
📌 Function: Deploy and support fighter jets and helicopters at sea.
B. Destroyers & Frigates
📌 Function: Provide defense against submarines and aircraft.
C. Submarines
📌 Function: Conduct stealth operations, reconnaissance, and defense.
8. Special Purpose Vessels
A. Research Vessels
📌 Function: Used for scientific ocean studies and deep-sea exploration.
B. Icebreakers
📌 Function: Break through frozen sea routes in the Arctic and Antarctic.
C. Dredgers
📌 Function: Remove sediment and deepen waterways.
D. Cable Laying Ships
📌 Function: Install submarine communication cables.
Conclusion
The maritime industry operates diverse vessels for trade, offshore support, military, and research. Each type of ship serves a unique function, making them essential for global commerce, energy, defense, and marine conservation.
