Submarine Cable Engineering

GateMarine is Türkiye’s leading company providing engineering, survey, installation, maintenance, repair, and protection services for submarine fiber optic and power cable systems. Submarine cable projects require integrated solutions covering route engineering, marine survey, cable laying, subsea jointing, mechanical protection, and lifecycle maintenance processes. GateMarine performs all these processes with its own cable and research vessel fleet, engineering team, offshore operation capability, and subsea equipment infrastructure.

In submarine cable projects, correct planning, accurate route selection, and the determination of appropriate protection methods are critical for system reliability. During the project planning phase, optimum solutions are developed by considering seabed conditions, depth, geological structure, fishing activities, vessel traffic, and environmental requirements.

GateMarine provides end-to-end services in submarine cable projects, including consultancy, design, survey, installation, subsea jointing, repair, and protection processes.

Submarine cable projects are long-term infrastructure investments that cover the entire process of planning, survey, engineering, laying, protection, and maintenance. Therefore, the technical evaluations made at the beginning of the project are critical in terms of system reliability and operating costs.

During the project design phase, GateMarine provides engineering consultancy on route optimization, cable type selection, evaluation of seabed conditions, and determination of protection methods. This approach ensures that cable systems operate with long service life, high safety, and minimal maintenance requirements.

Submarine cable systems may require maintenance and repair over time due to environmental effects, vessel traffic, fishing activities, and natural conditions. GateMarine provides integrated installation, maintenance, repair, and reconfiguration services throughout the entire lifecycle of cable systems.
