Offshore cable solutions O
Laurens Pots reveals the expansion of subsea cable capacity, enabling an expert in the sector to respond to industry demand.
ver the past decades, offshore cable solutions have become an increasingly essential part of the oil and gas sector. One expert in this field, TKF, has completed
several successful subsea cable projects up to 200 tonnes both in industrial distribution and for the oil and gas industry. As well as producing cables the company also works as an integrated supplier, offering the installation, assembly and on-site testing of cables.
Among the variety of designs is a so-called ‘dry design’, in which the triple core has a copper or aluminium jacket as a barrier against water. Tere is also a semi-dry version in which each individual core has its own aluminium or copper water barrier. Te fold of the metal water barrier welded shut over the entire length, which results in a very high- quality watertight seam. One final example of a design is that an extruded
HDPE jacket or a layer of impregnated PP wires can be applied over the steel armour
Reliable connections Reliable cable solutions are necessary for optimum offshore power transmission, even in extreme conditions. High quality is TKF’s top priority, starting with carefully selected reliable and quality suppliers. Te right expertise, certificates and test facilities guarantee this quality. By increasing its capacity in subsea cables up to 72kV, TKF is anticipating new developments and already meeting the requirements of the Offshore Wind Accelerator programme, which aims to reduce the CO2
footprint of renewable Fig. 1. TKF offers a variety of designs for its cable solutions.
Wind power is a growing market with increasing demand for subsea cables for the transmission of power from offshore wind farms. Tat is why TKF is reinforcing the development of cable solutions to meet this demand. Te design and construction of a new factory and testing facilities in the Netherlands will offer the opportunity to considerably increase capacity. Today’s capacity of 200 tonnes will be expanded to 1,500 tonnes with the construction of the new factory. Following this development, in 2016 TKF will have a factory that has its own transport to the available offshore ports and the possibility of delivering cables in longer lengths to meet the needs for turbine connections up to 72kV. To serve both the oil and gas industry and the wind power industry, the factory will be equipped to produce several designs.

energy . With the expertise
present, TKF wants to deliver a full service for offshore wind power. Tis means the company not only produces the cables but can also deliver an entire system, making the most reliable connection possible. Furthermore, the company is a complete supplier for high-voltage cabling for offshore substations (OSS), able to supply turnkey projects up to 170kV. l
