Category of Ocean Vehicles By Support (restoring) Forces -Supported by buoyancy force – Conventional displacement ship - Supported by Hydrodynamic force - Hydrofoil ships and Planning Hull ships, at Full Speed. -Supported by Aerostatic force (pressure) - Air cushion vehicles at full speed -Ground supported- Ocean drilling platform (median and shallow water) By Missions -Military Purpose: Aircraft carrier, Cruiser, Destroyer, Service vessel, Patrol boat (gun boat), Landing craft. -Non-military Purpose: a. Transportation: Passenger ship, Container ships, Bulk carrier (wheat, coal, ore, mineral), Oil tanker (very large), Specific vessel (LNG, etc.) By Missions (continues) -Non-military Purpose: b. Work Platform: Offshore drilling; Oil and gas production; Oceanography research; Electronic tracking and surveillance – satellite, communication, weather monitoring and navigation assistance; Ocean mining and dredging; Fishing, fish-processing; Offshore processing – sea water, minerals; Offshore power generation; Offshore service – construction, pipe laying, salvage and retrieval, Ice-breaker; Offshore support for personnel; By Missions (continues) -Non-military Purpose: c. Offshore commerce: Breakwaters, artificial harbors (marinas); Deepwater mooring (buoys); At sea storage (gas and LNG terminal); Recreation (artificial reef); Sea fish farms; Wind Mills; Renewable Energy; By Configurations Surface displacement
