Petropedia explains Tethered Diving
Tethered Diving allows petroleum engineers to carry out manned underwater operations. It is branch of commercial diving which is mainly used to complete offshore exploration and production tasks. It offers a wide range of services such as decommission support services, construction support services at offshore rigs, recovery and salvage services, spool installation services and support services for pipe or cable laying.
Working in remote and extreme environments is coupled with a lot of challenges; therefore, divers are required to be highly skilled and trained so that they can apply the appropriate methods at the correct place and time with complete understanding of the tools available.
