Frequently Asked Questions – Lifecycle Cable Services

NKT’s Lifecycle Cable Services provide comprehensive support across the full lifecycle of high-voltage cable systems – from installation through maintenance, potential repair, refurbishment to decomissioning or replacement. These services are designed to improve cable reliability, maximise asset lifetime, and minimise system downtime.

Our services apply to both modern and legacy cable technologies, onshore and offshore. We focus on high-voltage (HV) and medium-voltage (MV) cable systems – including oil-filled cables, gas-pressure cables, mass impregnated cables and extruded cables (PE, XLPE and HEPR).  

Yes – NKT delivers complete turnkey cable installation solutions, including engineering, procurement, logistics, civil works, cable laying, jointing, testing, and commissioning. We manage the full project lifecycle for both greenfield and replacement installations. 

Yes – NKT provides specialised maintenance for oil-filled and gas-pressure cable systems. Services include oil sample analysis, pressure monitoring, leak detection, system inspections, condition assessments, repairs, refurbishment and decommissioning. 

Our work is delivered by certified in-house cable jointers and service technicians, supported by trusted local partners when needed. All personnel are trained for complex high-voltage jointing and repair projects. 

Yes – NKT offers modernisation and refurbishment solutions including retrofits, replacement of outdated components, and upgrades of existing systems including the needed transition technologies connecting old and new cables – ensuring extended operational life and compliance with current standards. 

Yes – NKT maintains a stock of critical spare parts for both legacy oil-filled or gas-pressure cable systems and modern XLPE cables, for onshore and offshore use. We also support compatibility assessments for third-party systems. 

NKT provides cable services in nearly all global regions. Use our contact form to get in touch with us. 

Yes – our service teams are experienced in working with cables and accessories from a wide range of manufacturers. We offer technical assessments and integration support for mixed-system infrastructure. Contact us for tailored advice. 

If you are experiencing a cable fault, damage, or system outage, please contact us via our contact form. Emergency support is available for Service Level Agreement customers; all others will be responded to as soon as possible by our service team. 

Yes – NKT delivers a comprehensive suite of cable monitoring solutions for both onshore and offshore systems. Our platform integrates multiple technologies like Distributed Acoustic Sensing (DAS), Distributed Temperature Sensing (DTS), Automatic Identification System (AIS), Depth of Burial (DoB), Real Time Thermal Rating (RTTR) and our proprietary MakeSense^® health assessment tool. These systems detect acoustic anomalies (like excavation activity), temperature hotspots, burial depth variations, vessel movements, and other data or sensor inputs – then analyse and translate this information into actionable insights for risk mitigation. 

Continuous monitoring allows early fault detection, proactive maintenance planning, and improved network reliability. It helps reduce unplanned outages, operational risks, and long-term repair costs in critical power networks. 

NKT continuously develops advanced solutions to optimise offshore cable installation and maintenance. Our innovative technologies include state-of-the-art cable handling systems that improve safety and efficiency during repair operations. Additionally, we offer the Adaptive Rigid Sea Joint, a cutting-edge jointing solution designed for reliable, fast, and durable cable repairs in offshore environments. These innovations help reduce downtime, increase operational precision, and support the growing demands of the offshore energy sector.
