USS Regulus hard aground in 1971 due to a typhoon: after three weeks of effort, Naval salvors deemed it unsalvageable.. Marine salvage takes many forms, and may involve anything from refloating a ship that has gone aground or sunk as well as necessary work to prevent loss of the vessel, such as pumping water out of a ship—thereby keeping the ship afloat—extinguishing fires on board, to ...
A salvage situation arises when a shipowner accepts an offer of help from a salvor. To that extent, the arrangement is contractual, but it is not a contract for services with a pre-arranged fee (such as, say, a towage contract). Instead, the law provides that after the service is done a court or arbitrator will make an award taking into account:
The importance of environmental port regulation and management owes to the fact that the activities of ports are positioned in the intersection between energy and transport systems and connect a network of different sectors, markets, and value chains, making them a central part of the global economy.

Freight transport by sea has been widely used throughout recorded history. The advent of aviation has diminished the importance of sea travel for passengers, though it is still popular for short trips and pleasure cruises. Transport by water is cheaper than transport by air or ground, [1] but significantly slower for longer distances.
Seagoing tugs (deep-sea tugs or ocean tugboats) fall into four basic categories: The standard seagoing tug with model bow that tows almost exclusively by way of a wire cable. In some rare cases, such as some USN fleet tugs, a synthetic rope hawser may be used for the tow in the belief that the line can be pulled aboard a disabled ship by the ...
This allows operations at sea where mooring or anchoring is not feasible due to deep water, congestion on the sea bottom (pipelines, templates) or other problems. Dynamic positioning may either be absolute in that the position is locked to a fixed point over the bottom, or relative to a moving object like another ship or an underwater vehicle.
The access channel is a waterway that linking the basins of a port to the open sea. [6] The importance of the location of access channels is that it determines the oceanographic factors such as wave, tidal cycle, current, wind met by the ships in the channel.
