Hot-selling model for laying optical cables for dedicated power grids

The LS Marine Solutions large-scale cable-laying vessel and the ULSTEIN SX228 are currently among the most advanced and in-demand models for laying optical and power cables.

LS Marine Solutions Large-

Scale Cable-

Laying VesselLS Marine Solutions is building a state-of-the-art vessel with a cable loading capacity of 13,000 tons, designed for long-distance, high-voltage, and deep-water environments. This vessel is capable of simultaneously laying HVDC submarine cables and optical cables, making it ideal for dedicated power grids and offshore wind projects. It is technologically optimized for continuous, stable cable laying, minimizing cable connections and ensuring watertight integrity in submarine sections.

The vessel is expected to begin operations in 2028 and will be one of the largest and most competitive globally.

ULSTEI

N SX228 Fibre-Optic Cable Laying VesselThe ULSTEIN SX228 is a next-generation fibre-optic cable-laying vessel designed for high efficiency and sustainability. It features a deadweight of 8,200 tonnes, a cable capacity of 5,500 tonnes, and an underdeck carousel integrated into the cable tanks. Equipped with two firing lines, a 50-tonne A-frame, and an ROV hangar for cable trenching, it ensures safe and efficient operations in challenging offshore environments.

The vessel is optimized for future power cable operations and is suitable for both subsea telecommunications and renewable energy projects.

Royal IH

C Fibre Optic Cable Lay EquipmentFor projects requiring modular or vessel-integrated cable-laying systems, Royal IHC offers a portfolio of fibre optic cable lay equipment. Their systems provide accurate tension control, load measurement, and automation options, and can be integrated with different vessel types. Optional components like the Sea Stallion FibrePro and Fibre Pro Max ploughs allow for precise subsea cable installation, making them suitable for dedicated power grid deployments.

Key Considerations

Cable Type and Voltage: Ensure the vessel or equipment supports both optical and HVDC cables. Operational Depth: Deep-water capability is critical for offshore power grids. Automation and Safety: Modern vessels like the ULSTEIN SX228 and LS Marine Solutions models include automated cable handling and ROV support for efficient and safe operations.

Global Availability: LS Marine Solutions and Ulstein are among the few providers with vessels capable of long-distance, high-capacity cable laying, making them highly sought after in the market. These models represent the current hot-selling and technologically advanced solutions for laying optical cables in dedicated power grids, combining high capacity, operational efficiency, and adaptability to challenging offshore environments.
