End-to-End Offshore Cable Solutions: From Route Planning to Maintenance & Repair (with our international partner)
Marine cable networks—whether power transmission cables (HVAC/HVDC) supporting offshore wind farms or subsea telecom systems—form the backbone of modern global infrastructure. We deliver a comprehensive suite of services engineered to ensure that every cable is planned, installed, protected, and maintained to the highest operational standards throughout its full life cycle.
With advanced subsea technologies from our global partners—such as Saab Seaeye, Norbit, Sonardyne, Hemisphere GNSS, and EIVA—we support every phase of offshore cable projects with precision, safety, and long-term reliability.
Pre-Lay Surveys & Route Engineering
We provide high-accuracy survey operations to define the safest, most efficient, and technically sound route for cable installation.
🔹 Route Survey & Geophysical Clearance
- Detailed hydrographic and geophysical surveys to map seabed morphology, identify obstacles, and detect geological hazards.
- High-resolution multibeam mapping using Norbit sonar systems.
- Precision positioning and navigation via Hemisphere GNSS and EIVA NaviPac.
🔹 Burial Assessment & Seabed Analysis
- Evaluating seabed soil conditions to determine the optimal burial approach and ensure appropriate protection depth.
- Recommending trenching, ploughing, or jetting solutions based on sediment composition and risk-level requirements.
🔹 Pre-Lay Grapnel Run (PLGR)
- Mechanical clearance of the designated route to remove debris and obstructions prior to installation.
- Navigation support for PLGR operations using high-accuracy GNSS and acoustic tools.
Cable Laying, Burial & Real-Time Monitoring
During installation, we deliver precise operational support to ensure the cable is deployed accurately and safely.
🔹Laying Support & Precision Navigation
- GNSS and acoustic positioning systems (Sonardyne) to guide cable-lay vessels across the designated route with outstanding accuracy.
- Track-and-trace solutions to monitor the lay path and ensure compliance with engineering tolerances.
🔹 Real-Time Monitoring & Cable Tracking
- Continuous monitoring of the cable during lay and burial to verify depth of cover, route accuracy, and seabed interaction.
- Integration of EIVA systems for synchronized data visualization, QC, and operational reporting.
🔹 Offshore Manpower & Technical Expertise
We deploy certified, highly trained specialists, including:
- ROV pilots and supervisors
- Offshore survey engineers
- Cable-lay technicians and trenching support teams All trained on the latest EIVA, ROV, and subsea positioning workflows.
Inspection, Maintenance & Repair (IMR) (with our international partner)
Our IMR capabilities ensure the ongoing integrity, performance, and reliability of subsea cable systems.
🔹Routine & Advanced Inspection
- Visual, thermal, and structural inspections using Saab Seaeye ROV systems..
- Identification of wear points, exposure zones, over-bending, localized heating, and seabed instability.
🔹 Fault Detection & Localization
- Using Sonardyne acoustic navigation and tracking systems to precisely locate damage points or failures along the route.
- Rapid mobilization of ROVs and intervention teams to support emergency repair operations and restore system continuity.
