Offshore Renewables Solutions: Cable Protection, Survey, and Autonomous Technologies

The rapid expansion of offshore wind farms has intensified the need for reliable subsea cable protection systems. These cables play a critical role in transmitting power from offshore turbines to onshore grids, making their protection vital against mechanical damage, seabed movement, and environmental stressors. Cable failures can result in costly repairs, operational downtime, and energy transmission disruptions without proper safeguarding. Engineering solutions that account for site-specific conditions and long-term durability are essential to maintaining the efficiency and reliability of offshore wind networks.?

Subsea cable protection encompasses a range of engineered solutions designed to mitigate external threats such as seabed instability, fishing activity, and vessel anchoring. Traditional methods like trenching and concrete mattresses offer basic protection but may not be sufficient in dynamic marine environments. Advanced solutions provided by Unique Group, including its SeaSerpent? cable installation buoyancy system, enhance cable resilience and adaptability, ensuring optimal performance in challenging offshore conditions.

Unique Group provides comprehensive engineering solutions that support offshore wind projects throughout their lifecycle. From early-stage assessments in Pre-FEED and FEED to detailed engineering and installation, Unique Group delivers tailored protection strategies based on extensive analysis and industry expertise. Computational Fluid Dynamics (CFD) simulations and dynamic analysis allow for the optimization of cable configurations, reducing hydrodynamic forces and improving operational longevity. Installation analysis ensures that subsea cables are deployed efficiently, minimizing risks during the installation phase. The company’s Equipment Engineering Design services enable the development of robust protection solutions that account for environmental and operational challenges. At the same time, local analysis provides insights into site-specific factors to enhance long-term stability.

In addition to traditional cable protection systems, Unique Group offers retrofit CPS and cable repair solutions designed to extend the service life of existing offshore wind infrastructure. The CPS Bandage System reinforces aging subsea cables, adding durability against wear and environmental impact. Retrofit Dynamics solutions allow for adaptable cable protection in response to evolving offshore conditions, ensuring infrastructure remains secure as operational requirements change. An as-built analysis ensures installed protection measures meet design specifications and performance expectations. For highly customized engineering challenges, Unique Group’s Special Projects team develops innovative solutions tailored to unique offshore requirements.

Beyond cable protection, Unique Group provides a range of survey and autonomous solutions that support the offshore renewables industry. The company offers advanced survey equipment, Autonomous Surface Vehicles (ASVs), Unmanned Surface Vehicles (USVs), and Remotely Operated Vehicles (ROVs) to facilitate offshore wind farm site assessments, subsea inspections, and environmental monitoring. These technologies enable efficient data collection, reduce the need for human intervention in hazardous environments, and improve the accuracy of offshore wind farm planning and maintenance.

?Sustainability is a key consideration in offshore wind farm development, and Unique Group integrates eco-friendly materials and low-impact installation techniques into its subsea cable protection solutions. The SeaSerpent? system facilitates the safe and efficient laying of cables in shallow waters by providing controlled buoyancy, aiding in precise cable positioning, and minimizing seabed disruption. Uraduct? is designed to shield fiber optic cables, power cables, umbilicals, and flowlines from external hazards, enhancing the longevity and reliability of subsea installations. Seaflex? Mono Buoyancy Units (MBUs) and Inflatable Buoyancy Units (IBUs) ensure precise cable positioning while reducing seabed disruption. These solutions contribute to streamlined installation, lower environmental impact, and improved resilience of offshore power transmission networks.
