When it comes to maritime logistics, North Sea Logistics (NSL) is among the leading British suppliers. NSL catamarans are being used for off-shore windfarms in British waters. eneo PNR network video recorders are part of the video surveillance systems on bord.
eneo customer, Boat Electrics & Electronics Ltd. (BEE Ltd.), provides support services to one of the UK’s leading off-shore, energy servicing companies, North Sea Logistics (NSL).
Off-shore, windfarm-generated, energy production has seen massive growth around UK waters in recent years. Engineers require access to the turbines all year round; initially during the build of the windfarm turbines themselves, which are fixed to the sea bed, and then for their on-going maintenance. The turbine access process has been well thought through and is most commonly achieved using specialist, aluminum, Windfarm Service Level 1, catamaran boats.
These boats are designed with a flat bow which presses against the turbine tower wall for docking. The boats stay in position, using only the propulsion of its engines, whilst engineers disembark. The engineers then climb a ladder on the turbine tower wall to a platform, sitting at around 8m above sea level, and from here, they can enter the turbine through a door. Most modern turbines have a lift inside which is used to take the engineers to the generator and other active parts of the turbine to work.
Windfarm numbers are increasing with as many as 100 turbines per farm, spread up to ten miles out to sea. The result is that each farm can have two or three Windfarm Service boats in continuous use at any time.
The catamarans are worth between £2 and £3M each and are designated high-speed, light craft. They are ideal for this work due to their stability and maneuverability. They carry up to 12 passengers, three crew and a significant amount of equipment. As well as Windfarm Service Level 1 categorisation, they meet stringent, DNV-GL, maritime safety compliance standards.
BEE Ltd., which has facilities at Irvine, Kip, Argyll and Cowes ports, provides comprehensive, electronic system installation and support for the windfarm servicing catamarans and many other types of boats. The electronic systems covered include radar, GPS, systems for navigation, satellite, chart computers, echo sounders, radio systems and CCTV surveillance. The latter is used for both security and health and safety purposes.
“IP surveillance cameras monitor the engine room, which is a class requirement for boats with un-manned engine rooms,” explained Matt Davy of BEE Ltd. “They also monitor fore and aft decks, port, starboard and saloon passenger areas, totaling ten cameras in all. The prime purpose of the CCTV system is to ensure health and safety, as well as give the captain visibility of all parts of the boat from the bridge, in real time. It also provides security for when the boat is docked in port.” An eneo PNR-5316 network recorder, with 6 TB hard drive and iRAS management software, provides live camera viewing on the catamaran’s existing display systems, meaning no additional, specific monitors are needed. The PNR records each camera’s 2MP video stream in Full HD, real-time, for over 31 days. Playback of recorded images is provided on the same displays.
Matt Davy added, “The catamarans are built with Panasonic cameras fitted, so the eneo recorder had to integrate with these using the ONVIF universal protocol. This integration was seamless and has proven to be extremely reliable and effective."
