A turboexpander, also referred to as a turbo-expander or an expansion turbine, is a centrifugal or axial-flow turbine, through which a high-pressure gas is expanded to produce work that is often used to drive a compressor or generator.

In fluid dynamics, turbulence kinetic energy is the mean kinetic energy per unit mass associated with eddies in turbulent flow.

Turbulent flow is fluid motion characterized by chaotic changes in pressure and flow velocity.

see manoeuvring trials.

A reversible electric motor which, through a system of gears, can be used to turn slowly a large diesel engine or steam turbine and gearbox assembly.

Projects that companies perform from design to completion when it is ready to hand over to the client.

A device providing a connection point between an offshore unit and the combined riser- and mooring- systems, allowing the unit to rotate around the turret (weather vane) without twisting the risers and mooring lines.

The single point mooring system.

A mooring turret is installed at the centre of the ship, where all anchoring lines terminate and around which the ship is free to make rotations, enabling it to select a favourable heading for the environment.

Turret transfer system is designed to manage the production and service lines which pass through the central moonpool of the hull as it pivots around its central mooring point.

In service, SCHIEHALION will operate above the field of four main drilling centres, secured by 14 anchor legs made up of 160-mm diameter studless chain and wire rope, fixed to anchor piles arranged within a 1650-m radius.

The TVD (true vertical depth) of a well describes the length of a perpendicular line from the surface to the bottom of the well.

The upper cargo stowage compartments or the space between any two adjacent decks.

Twin-skeg afterbody can be highly beneficial on ships with full forms, especially when low draught or high beam-to-draught ratio is required.

Twin-turbo refers to an engine in which two turbochargers compress the intake fuel/air mixture (or intake air, in the case of a direct-injection engine).

Twisted pair cabling is a type of wiring in which two conductors of a single circuit are twisted together for the purposes of improving electromagnetic compatibility.

A mechanical locking device at the corner of a container. Conventional twistlocks are locked and unlocked manually with operating rods.

Fluid motion can be said to be a two-dimensional flow when the flow velocity at every point is parallel to a fixed plane.

The "two fluid" reactor has a high-neutron-density core that burns uranium-233 from the thorium fuel cycle.

Paints which are supplied in two separate containers and which have to be mixed before use.
