Industry & Occupation
Classification
Summary
Specialized technical job that operates dedicated cable laying ships and equipment to lay telecommunications cables on the seabed, from seabed surveys to cable laying and installation.
Description
Submarine cable layers specialize in laying telecommunications cables on the seabed. First, they survey the seabed topography and obstacles to plan the optimal route. They operate specialized equipment mounted on cable laying ships (winches, plows, cable drums, etc.) to lower the cable to the seabed with appropriate tension. In deep-sea areas, they use diving operations or ROVs (remotely operated vehicles) in combination to connect and bury the cables. Originally an offshore construction job, they carry out work while coordinating team operations on board, paying attention to safety management and environmental protection.
Future Outlook
With increasing data traffic, demand for submarine cables is on the rise. Needs for specialized technicians remain stably high due to the introduction of new technologies and compliance with environmental regulations.
