Port of Leith, Edinburgh

In March 2013 Forth Ports was named Edinburgh’s greenest company in awards that recognise the city’s best businesses. Lighting innovations at Leith docks were among the initiatives that helped the UK port operator clinch the prize at the Edinburgh Chamber of Commerce Business Awards. There was more to the lighting improvement, however, than just its green credentials.

Lighting challenges

This is Shed 3 – a specialist bulk store for storing food commodities, most often grain

It’s an environment where spontaneous ignition is possible and dust a constant hazard

The 400W SONs were clearly struggling to provide adequate illumination - each one actually drawing about 440W

5


Lighting challenges

Lamp replacement could only be carried out when the shed became empty of cargo

That could mean a wait of a few days or even a year

When there is product stored, you can't access the lighting for maintenance

Replacement lights would have to have long life and need limited maintenance

6


Lighting challenges

In the workshop 400W HPS high bays caused work delay by taking up to 30 minutes to re-strike

The need for regular replacement involved clearing the floor of plant being worked on so that the scissor lift could be used to access fittings

In the cruise ship terminal lamp replacement involved team of 3 men

The scissor lift had to be taken there via public highway with a two-vehicle escort, then dismantled to get through the door and re-assembled inside

Having to work around cruise ship timetables and staff scheduling meantfailed lights could end up waiting a while, never mind the cost

The solution

It must be a food product safe luminaire to avoid dust build up and comply with food regulations

Solution 113x400W SON high bays replaced in Shed 3 with 8x172W Dialight LED high bays

Solution 2400W HPS in workshop and cruise terminal replaced with 150W Dialight LED high bays

The result

Changing to LED resulted in >75% energy saving in Shed 3

Over 60% saving in the other areas

Options to introduce presence and daylight detection to further improve efficiency

Equivalent CO2 reduction in all areas

CO2 emissions cut by 0.4 tonnes per

light annually

Burden of maintenance eliminated as each LED high bay carries Dialight's 5-year performance warranty

Testimonial

“As one of the UK’s largest ports groups, we take our environmental responsibilities seriously. We are delighted with the reduction of energy consumption achieved with the added benefit of elimination of maintenance and the associated disruption. Together these help us to operate more efficiently and deliver operational benefits while we are also minimising our impact on the environment. We are now actively examining other areas of the business which could benefit from this technology.”

Dr. Derek McGlashan, Environment and Energy Manager, Forth Ports Limited
