FEATURE CABLING & CABLE MANAGEMENT Next step for cable installation vessel
Nexans has hosted the grand block ceremony that represents a key step in the construction of its cable installation vessel, the Nexans Aurora. The vessel’s hull is currently being built at the CRIST shipyard in Poland. It will be completed at Ulstein Verft in Norway, with delivery planned for 2021
T
he grand blocks are the major components in the construction of the
hull. They are being assembled at CRIST, in the Polish port of Gdynia. The Aurora design is based on the
combined experience of Nexans, Skipsteknisk, Ulstein Verft and MAATS Tech. The aim is to produce a subsea cable and umbilical systems installation vessel for worldwide operations, covering the full range of shallow and deep subsea activities. Ragnhild Katteland, vice president
subsea and land systems, Nexans, says: “The construction of this ground-breaking cable laying vessel is a major milestone in our long term strategy for the future of
the global energy market. It will enable Nexans to maintain and extend our position as an important turnkey player in the field of subsea cables. In particular, the capability to install cables at even greater depths will contribute to securing the world’s energy supply and advancing the the shift to environmentally friendly green electricity from renewables. Aurora will be a crucial asset.” “The vessel is well prepared for complex
construction tasks in severe weather conditions anywhere in the world,” says Ulstein Verft’s managing director, Lars Lühr Olsen. “Ulstein Verft will carry out the final outfitting, commissioning and testing prior to the vessel’s delivery in
2021, and we are well prepared and eager to finalise this newbuild project.”
BRINGING ENERGY TO THE WORLD The Aurora builds on over a century of Nexans’ experience to bring cable installation to the next level in terms of capacity and capability. With a 10,000 ton capacity, split
turntable, and a world leading vessel design, Aurora is well prepared for complex construction tasks in severe weather conditions anywhere in the world. The DP3 cable laying vessel represents a next step in offshore renewables with high manoeuvrability and station keeping capabilities. She will be outfitted for power cable laying, including bundle laying, cable jointing and repair, and cable system protection and trenching. The vessel will play a vital role in
installation of Nexans’ high voltage (HV) submarine cables that will bring more energy to the world, helping connect offshore wind farms to the grid, supporting electrification of offshore oil and gas installations, and creating interconnectors between countries.

NEW 25-YEAR PLASTIC CABLE TIE M
HellermannTyton’s new PVDF Solar Tie delivers all-weather performance and longevity in an otherwise familiar looking fastener design, thanks to its unique material. It is said to be the industry’s first commercial-scale, plastic solar tie, and is designed to last more than 25 years
anufactured from polyvinylidene fluoride, or PVDF, this outdoor tie
exhibits some of the highest UV, chemical and thermal resistance of any plastic resin. With a maximum operating temperature of 284 degrees Fahrenheit, few materials come close. Metal ties may seem like a better
option, but they are known to sometimes slice through electrified solar cables, which can result in catastrophic faults.

Some metal ties require a hand tool to crimp them closed, which can be a time-consuming inconvenience. “Metal is expensive and hard to install,”
says Nick Korth, product marketing manager – energies. “Some cable tie manufacturers are
selling cheap plastics that don’t last long. HellermannTyton is completing its suite of wire management materials, enabling the introduction of a Solar Tie that combines
the longevity of metal and the ease of installation and wire safety customers expect from a polymer-based cable tie.” The grey colour indicates PVDF, which
provides inspectors visual confirmation that a solar-specific wire management product was used on the installation and can speed site approval.
