An umbilical cable or umbilical is a cable and/or hose that supplies required consumables to an apparatus, like a rocket, or to a person, such as a diver or astronaut. It is named by analogy with an umbilical cord .
One of the earliest and most critical tasks in a submarine pipeline planning exercise is the route selection. [5] This selection has to consider a variety of issues, some of a political nature, but most others dealing with geohazards, physical factors along the prospective route, and other uses of the seabed in the area considered.
Lay methods consist of J-lay and S-lay and can be reel-lay or welded length by length. Pipelaying ships make use of dynamic positioning systems or anchor spreads to maintain the correct position and speed while laying pipe. Recent advances have been made, with pipe being laid in water depths of more than 2,500 metres (8,200 ft).
ROV at work in an underwater oil and gas field. The ROV is using a torque wrench to adjust a valve on a subsea structure.. A remotely operated underwater vehicle (ROUV) [citation needed] or remotely operated vehicle (ROV) is a free-swimming submersible craft used to perform underwater observation, inspection and physical tasks such as valve operations, hydraulic functions and other general ...
Subsea production systems are typical wells located on the seabed, shallow or deep water. Generally termed as Floating production system, where the petroleum is extracted at the seabed and the same can be tied back to an already existing production platform or an onshore facility.
Alternating-current (AC) submarine cable systems for transmitting lower amounts of three-phase electric power can be constructed with three-core cables in which all three insulated conductors are placed into a single underwater cable. Most offshore-to-shore wind-farm cables are constructed this way.

The piping can be used during interventions.They encapsulate multiple coiled tubing and electrical strings into a single string which can be deployed by one conventional unit.
