1. Dry Cargo Ships (Carry non-liquid cargo)

• General Cargo Ships: Multi-purpose vessels for break-bulk, packaged goods.
• Bulk Carriers: Carry unpackaged bulk commodities like ore, coal, grain.

o Size Categories for Bulk Carriers (Critical for your list):

* Panamax (~60,000 – 80,000 DWT) Fits the original Panama Canal locks.
* Post-Panamax (Too wide for the old locks)
* Capesize (80,000+ DWT, typically 180,000 DWT) Too large for canals, must go via the Cape.
* Very Large Ore Carrier (VLOC) & Valemax (Ultra-large for Brazilian iron ore).
• Container Ships: Carry standardized containers (TEUs).

o Size Categories for Container Ships:
* Feeders (Sub-3,000 TEU)
* Panamax (~3,000 – 5,000 TEU) Old standard for the canal.
* Post-Panamax (5,000 – 14,000 TEU)
* New Panamax (Neo-Panamax) (Up to ~14,000 TEU) Fits the new canal locks.
* Ultra Large Container Vessel (ULCV) (14,000+ TEU, up to 24,000+ TEU).
• Roll-on/Roll-off (Ro-Ro) Ships: For wheeled cargo (cars, trucks, trailers).
• Heavy Lift/Project Cargo Vessels: For oversized industrial equipment.
• Reefer Ships (Freezer Vessels): Refrigerated cargo ships for perishables.

2. Tanker Ships (Carry liquid cargo in bulk)

• Crude Oil Tankers: Transport unrefined crude oil.

o Size Categories for Crude Tankers:
* Panamax (~60,000 – 80,000 DWT)
* Aframax (80,000 – 120,000 DWT) Average Freight Rate Assessment size.
* Suezmax (~120,000 – 200,000 DWT) Max for the Suez Canal.
* Very Large Crude Carrier (VLCC) (200,000 – 320,000 DWT)
* Ultra Large Crude Carrier (ULCC) (320,000+ DWT).
• Product Tankers: Carry refined petroleum products (gasoline, diesel).

o LR1 (Long Range 1), LR2, MR (Medium Range), Handysize.
• Chemical Tankers: Carry chemicals, often with specialized coated tanks (IMO Type I, II, III).

o Gas Carriers:
o LNG Carriers (LNGC): For Liquefied Natural Gas at -162°C.
* Conventional (~125,000 – 175,000 m³)
* Q-Max (~266,000 m³) Largest, for Qatar trade.

o LPG Carriers (LPGC): For Liquefied Petroleum Gas (propane, butane).
* Very Large Gas Carrier (VLGC) (Typically 75,000 – 90,000 m³).
o Ethylene Carriers: For petrochemical gases.
• Bitumen/Asphalt Tankers: Heated tanks for viscous products.

3. Passenger Ships

• Cruise Ships
• Ferries (Ro-Pax: Roll-on/Roll-off Passenger)
• Ocean Liners (Historical/niche)
• Yachts / Mega-Yachts

4. Offshore Vessels (Support offshore industry)

• Offshore Support Vessels (OSV): Platform Supply Vessels (PSV), Anchor Handling Tug Supply (AHTS).
• Drill Ships & Semi-Submersible Rigs (Mobile Offshore Drilling Units – MODUs).
• Pipe-Laying Vessels
• Cable-Laying Vessels
• Floating Production Storage and Offloading units (FPSO/FSO)

5. Special Purpose / Industrial Vessels

• Tugs
• Dredgers
• Research Vessels
• Icebreakers
• Salvage Vessels
• Fishing Vessels (Trawlers, Factory Ships)
• Livestock Carriers
• Cement Carriers
• Heavy-Lift / Semi-Submersible Vessels (Dock ships for carrying other vessels/platforms).

6. Naval & Government Vessels

• Naval Ships: Aircraft Carriers, Destroyers, Frigates, Submarines, etc.
• Coast Guard Cutters
• Patrol Boats
• Lighthouse Tenders

7. Size/Canal-Based Categories (Cut across functions)

These are the key “Max” terms for chartering and operations:
• Panamax: The maximum dimensions that could fit the original Panama Canal locks. Applies to bulk carriers, container ships, and tankers.
• New Panamax or Neo-Panamax: The maximum for the new, expanded Panama Canal locks. Primarily used for container ships.
• Suezmax: The maximum dimensions for the Suez Canal. Primarily a tanker size category.
• Capesize: Bulk carriers and tankers too large for the Suez or Panama Canals, forcing a route around the Cape of Good Hope or Cape Horn.
• Malaccamax: The maximum draft for the Strait of Malacca (~21m). The practical size limit for ULCCs and the largest container ships trading in Asia.

Quick-Reference Integrated List (Merging Your List with Additions):
• Container Ships (Feeder, Panamax, Post-Panamax, Neo-Panamax, ULCV)
• Tanker Ships
o Oil Tankers (Crude: Aframax, Suezmax, VLCC, ULCC)
o Product Tankers (MR, LR1, LR2, Handy)
o Chemical Tankers
o Gas Tankers (LNG Carriers, LPG Carriers, VLGC, Ethylene Carriers)
o Bitumen Tankers
• Passenger Ships (Cruise Ships, Ferries)
• Naval Ships
• Offshore Ships (PSV, AHTS, Drill Ships, FPSO)
• Special Purpose Ships (Tugs, Dredgers, Research, Cable-Layers)
• Bulk Carriers (Handysize, Supramax, Panamax, Capesize, VLOC)
