Bright lights and big buoys at Seawork

Also on display from Hydrosphere, situated on stand A77, will be the new DB2000 Data Buoy platform fitted with a selection of environmental sensors and the Vega VSL-73 sector light, chosen for several applications by Trinity House.

The VRL-74 LED range light is designed for high intensity applications, with the ability to provide a day range of more than 10NM and a night range of more than 30NM.

Incorporating the latest in LED lens technology, the VRL-74 gives a vertical divergence of less than 3° at 50% of peak intensity level.

Featuring a modular design, the VRL-74 can be configured for individual applications. It is constructed as a vertical array containing the number of light elements required for the specific application. Multiple arrays can be mounted parallel to each other for increased intensity or, for lower range applications, a spreader lens can be fitted to increase the horizontal divergence. The light is programmed as a single unit regardless of how many lenses are used.

The VSL-73 uses advances in LED optics technology and design that have taken place over the last two years to create a wide angle sector light highly engineered to provide a sharp boundary between colours.

The VSL-73 can be configured to have a range of up to 12NM and caters for sector angles from 2° to 360°, along with an angle of uncertainty better than 0.5° colour to colour and 1° at sector edge. The low powered lighting also makes it possible for use in solar powered applications. Each light can be fully customised by range, colour and sector for each application.

The DB 2000 is a medium sized data buoy, suitable for use in near shore or inshore locations where a stable data buoy that can support a significant payload is required. Its 1.9m diameter hull provides 2,000 kg of buoyancy.

With a non-slip deck and other inherent safety features, the buoy is large and stable enough for a person to safely climb on it to work. The galvanised steel central core structure allows through hull access for deployment of subsea instruments, with underwater instrument mounting points inside and outside the central structure. The structure allows for both single and double mooring arrangements.

Hydrosphere supplies, installs and maintains complete aids to navigation solutions and has supplied all of the UK lighthouse authorities and most of the major UK port and harbour authorities, offshore wind and wave power installations, marinas, aquaculture sites, and research institutions.
