Unlike a low voltage installation which is generally designed and constructed in accordance with technically prescriptive requirements, most high voltage installations are unique to their application and are designed according to electrical engineering safety principles. As a result, the Regulations that apply set fundamental safety requirements only. High voltage installations require planned ongoing maintenance and are often designed as a part of or closely interact with the supply or distribution of electricity.
Reflecting the engineered installation philosophy, the Regulations achieve control through identifying the factors that need to be addressed during design and construction and by defining characteristics that are considered to be unsafe. Regulation 20 external link defines electrically unsafe works and installations. Works and installations are unsafe if:. There is a requirement to implement a safety checking system Regulation 40 external link that must:. Regulations for the design, construction and inspection of high voltage electrical installations take into account the fact that each installation will be different, and are designed according to electrical engineering safety principles.
Design, construction and inspection of high voltage electrical installations. Last updated 4 September at Installations and networks High voltage electrical installations.
Standards and testing. High risk product list. Supplier declaration of conformity. Household and similar appliances. Lighting electrical appliances and accessories. Low voltage electric wires and cables. NKT has the in-house capability for addressing both aspects. Works prior to cable laying During the survey and route engineering we will ultimately reduce cost and project risk by selecting the optimum route and understanding the seabed soils.
The cable route is prepared for the coming cable laying. Cable laying We use purpose-built equipment and well-proven processes based on our vast experience to ensure reliable cable laying, jointing and pull-in to shore and the platform.
Burial protection Trenching is closely connected to the cable laying and the burial method is specifically selected for each project to ensure the right cable protection through the lifetime of operation.
Works following cable laying and burial In the last phase, the cable route area is restored and the cable system is tested. Service The most efficient way to ensure a smooth transition and knowledge transfer from the cable installation project to the link in operation is to do the repair preparedness plan.
NKT offshore engineering centre in Rotterdam. A highly focused team with one goal — lowering the risk during installation and adding value to the tenders and projects. This is achieved through comprehensive knowledge and close cooperation, both in the team, with other departments and with the customer. We aim to identify potential risks at an early stage in order to engineer out or mitigate risk as far as is practical.
Typically, offshore work is 8x more expensive than onshore work so there is a cost saving incentive as well as the resulting QHSE and time saving benefits of early engineering. Success in difficult conditions Through almost a century of offshore installation experience in all parts of the world, we have learned how to handle all conditions from installation in the busy sea port of New York, the harsh weather conditions in the North Sea off the Norwegian shore to environmentally sensitive areas off the coast of Germany.
Goliat, Norway The Goliat oil and gas field, km off the Northern coast of Norway, was discovered in and is operated by Eni Norge. The production of oil and gas from a FPSO floating, production, storage and offloading platform started in High Voltage Offshore Cables We are world leader's when it comes to high voltage offshore cable systems, and we pioneered the industry's first offshore HVDC link in Learn more.
