Among some of the more challenging locations that The LED Industrial Lighting Co. has surveyed, are the container cranes at the Royal Portbury Docks which are part of the Port of Bristol.
The Port of Bristol is one of the fastest growing ports in the UK. This deep-water dock looks out over the Severn Estuary. It is a major port for the import of vehicles and containers into the UK and has the largest entrance lock into any UK port, accommodating vessels up to 41m beam, 290m length and 14.5m draft.
There are a number of cranes at Royal Portbury and in 2016, Crane 2 required a lighting refurbishment. The existing 1000W HPS floodlights were located along the boom, backreach and beneath the driver cabin at approximately 30m above the quayside.
Maintenance-free LED Solution against saline spray
The project brief was to provide a maintenance-free LED solution and to achieve 150 lux on the vessel deck under the driver’s cabin. Given the harsh marine environment, the fittings required to be IP66 and protected against the extreme corrosion of saline spray.
The existing fittings were corroding and many of the lamp bulbs failed due to the lifting boom and vibration from wind and quayside trackway. Some of the floodlights were also very difficult to access and required specialist cherry-pickers to be hired, with the inevitable cost.
Following a survey of the crane and quayside, a lighting design was commissioned. The engineers required to re-use the existing lamp positions, so identifying an LED solution to provide 150 lux under the driver cabin would prove challenging.
