The export cables are of a similar design as inter-array cables but have a higher voltage, typically 100 to 220 kV. High cable capacity, efficiency and gentle handling of cables are the key elements in such vessels. Shallow draught can be an important design element in export cable laying vessels as some vessels go close to land to terminate and load cable.
The SX165 is a large, modular and flexible platform for power cable laying operations. The cable tank and carousel are either on the deck or below the deck if requested. The vessel has a high deadweight capacity of up to 15,000 tonnes and cable capacities of up to 10,500 tonnes.
The LX109 is a high-capacity, highly efficient cable-laying vessel with compact dimensions. The ULSTEIN Cable Arch system, combined with the open-top vessel design, results in the capability to load and lay 12,500 t power cable as one single piece.
