Cable Installation

GateMarine provides end-to-end engineering and offshore execution services for subsea cable installation projects. Subsea fiber optic cables and subsea power cables for telecommunications and energy applications are designed and installed based on project requirements, seabed conditions, and environmental constraints.

Installation activities include subsea cable route engineering, evaluation of marine and subsea survey data, offshore installation planning, seabed placement or burial, and mechanical protection solutions. GateMarine develops project-specific installation methodologies to ensure safe, reliable, and long-term cable performance across varying seabed and depth conditions.

One of GateMarine’s most critical technical strengths lies in the integration of subsea jointing systems for fiber optic and power cables. Subsea joints represent a key reliability component of cable systems, and this field constitutes one of GateMarine’s core engineering know-how areas, built on extensive design and offshore experience.

All subsea cable installation operations are executed in accordance with international standards, operational safety requirements, and environmental responsibility principles.
