A tropical rainforest climate or equatorial climate is a tropical climate usually found within 10 to 15 degrees latitude of the equator.

A tropical savanna climate tends to either see less rainfall than a tropical monsoon climate or have more pronounced dry season(s). In tropical savanna climates, the dry season can become severe, and often drought conditions prevail during the course of the year.

the troposkein is the curve an idealized rope assumes when anchored at its ends and spun around its long axis at a constant angular velocity. A Darrieus wind turbine has blades that approximate the shape of a troposkein to minimize bending stresses.

A vertical or inclined space or passage formed by bulkheads or casings, extending one or more deck heights, around openings in the decks, through which access can be obtained and cargo, stores, etc...

An internal combustion engine in which the connecting rod is directly connected to the piston by a gudgeon pin (also called piston pin).

Patented bow ramp/door arrangement developed by TTS Ships Equipment. A collision bulkhead door is separated from the steel frame positioned forward.

Novel mooring equipment developed by TTS Marine. TTS WB can hold the mooring rope like a normal bollard but can also tighten and release it in a controlled way.

Tubes are generally small-diameter thin-wall pipes. Tubes are to meet the same general requirements as pipes.

A generic term for a family of hollow section products of various cross-section configuration.

Small vessels designed to tow or push large ships or barges. Tugs have powerful diesel engines and are essential to docks and ports to manoeuver large ships into their berths.

The fall-in of the ship sides amidships.

Tundra climates ordinarily fit the Köppen climate classification ET, signifying a local climate in which at least one month has an average temperature high enough to melt snow (0 °C (32 °F)), but no month with an average temperature in excess of 10 °C (50 °F).

A watertight access passage surrounding the propeller shaft fitted on a ship where the machinery space is positioned towards midships.

Turbidity is a measure of water clarity how much the material suspended in water decreases the passage of light through the water.

A turbine is any motor in which a shaft is steadily rotated by the impact of a current of steam, air, water or other fluid directed from jets or nozzles onto the blades of a wheel.

The number of blades is selected for aerodynamic efficiency, component costs, and system reliability.

As of 2020, most end-of-use blades are temporarily stored or sent to landfills rather than recycled.

Turbine inlet air cooling is a group of technologies and techniques consisting of cooling down the intake air of the gas turbine.

An electric generator powered by a steam turbine connected to its drive shaft.

A turbocharger, colloquially known as a turbo, is a turbine-driven, forced induction device that increases an internal combustion engine's power output by forcing extra compressed air into the combustion chamber.
