Navigational lights for the Firth of Forth
The Queensferry Crossing over the Firth of Forth has been installed with new navigational lights in a £1.35 billion project involving more than 10,000 people.
Hydrosphere supplied the Vega LED navigation lights for the crossing after having first being approached by Ramboll Consulting to design the specification on what type of LED lights might be mounted, intensity required and the installation of a monitoring system.
“We won this tender with SES because we provided the specified kit, with consultancy and technical support both at the tender time and right through to installation and commissioning,” said Jeff Gibson, sales director, Hydrosphere.
Hydrosphere recommended 44 LED Vega VLB 36 lights for the project both for their high efficiency and standards of reliability.
Hydrosphere supplying Vega lights fitted with internal alarm boards which signal in the event of a light failure back to a central control position. Each light is powered by a local battery back-up power supply to maintain power to the lights in the event of a grid power failure.
“What you try to do in these situations for a client is plan for avoiding any ‘single point of failure’ in a system,” said Mr Gibson.
The tender was awarded as part of a larger electrical package, to SES Engineering Services (SES). SES went on to win the prestigious Construction News Specialist Awards’ Project of the Year (subcontract over £6m) for its work on the Queensferry Project.
