When laying a cable, the cable itself is a hazard as it can get caught on the umbilical cable. Seabed tractors are usually somewhat slower and less agile than other ROUVs. They can be used together with another remotely operated underwater vehicle to enhance the overview and to survey the progress and performance. [2] [3]

A Vertebrae Bend Restrictor (VBR) is used in the oil and gas industry as part of offshore deep sea drilling operations. It is designed to prevent damage to an umbilical cable from overbending. It offsets the action of applied loads which could kink or buckle the internal conduits of an umbilical, cable, flexible riser pipe or MUX line.
OCM – offshore construction manager; OCS – offshore construction supervisor; OCTG – oil country tubular goods (oil well casing, tubing, and drill pipe) [23] OD – outer diameter (of a tubular component such as casing [citation needed]) ODT – oil down to; OFE – oil field equipment; OFST – offset vertical seismic profile
The umbilical components are connected to the appropriate connectors on the diver's equipment, mostly on the helmet or full-face mask, and the strength member is usually attached to a strong D-ring on the diver's harness using a screw-gate carabiner or similar connector which will not accidentally release or snag on lines. The US Navy specify a ...
Ulstein Verft was established in 1917, and is the largest employer in the group. The yard specialises in constructing advanced vessels, the latest being cable laying vessels, offshore wind service vessels, expedition cruise vessels, yachts and passenger (RoPax) vessels. [7]
A submarine pipeline (also known as marine, subsea or offshore pipeline) is a pipeline that is laid on the seabed or below it inside a trench. [1] [2] In some cases, the pipeline is mostly on-land but in places it crosses water expanses, such as small seas, straits and rivers. [3]
A cable protection system (CPS) protects subsea power cables against various factors that could reduce the cable's lifetime, when entering an offshore structure.. When a subsea power cable is laid, there is an area where the cable can be subjected to increased dynamic forces the cable is not necessarily designed to withstand over its lifetime.
