When it comes
to ports, one of the most crucial elements is that of lighting.
is vital to the safety and the security of port operations. Good quality,
reliable illumination allows successful navigation on the waters and people to
find their way along jetties, docks and terminals - something that's particularly
important either at night or during poor weather conditions.
senior consultant of maritime and ports at URS/Scott Wilson says:
"Lighting is provided for safe working in a port and is fundamental to the
safe and secure operation of a port facility for both vehicular and foot
traffic. The correct light levels are required to avoid simple trip and slip
hazards to personnel and the safe handling of goods and equipment that exists
in a busy port environment."
There are many
suppliers for port lights - the top brands including GE, Phillips, Prismalence,
Phosco, Sill, Abacus, Thorn, Holophane, Urbis and Rudd. Natasha Boukhary,
global corporate communications manager at DP World says that the company goes
for a wide ranging mix of suppliers for different requirements. "Typically
we would go for products such as Phillips Comfortvision SNF111 MB 600W (or
1000W) SON. However, now we are starting to engage with suppliers of
alternative low energy consumption products such as Prismalence.
stevedoring equipment lighting, DP World has standardised the supplier and
opted for energy saving Prismalence," continues Ms Boukhary. "While
for refurbishment of existing stevedoring equipment, DP World uses where
possible Prismalence lights."
So what are the
common factors that ports look for when selecting lighting products? Aside from
quality, reliability and power, ports also look at distribution vs energy
consumption, light pollution, size of fittings and accessories, bulb life, and
important issue - especially in an economically challenging climate is that of
value for money. "It will depend on individual circumstances of each
installation as to what represents good value for money," says Mr Steele.
"The companies who do not offer good value for money are those who offer
cheap alternatives whilst claiming they provide an equal or equivalent,
specification to those supplied by reputable suppliers. In the end the products
that can be said to offer ‘good value for money’ are those that provide the
longest life and exceed the required specification."
adds that, more specifically, high pressure sodium lamps still represent value
in low quantities, or in countries where import duties and taxes are high as
they can generally be procured in country. However, new build terminals are
identified as providing opportunities for low energy consumption productions
and where power utility rates are expensive. With regard to stevedoring
equipment, Prismalence lights represent good value for money. "Other LED
lighting solutions are coming to the market by way of industrial port
applications and no doubt will be good comparable solutions,” says Ms Boukhary.
lighting solutions are, of course, more expensive, but depending on location
and cost of energy, the returns on investment are very favourable,” she adds.
“The current economic climate has not deterred people from looking closely at
energy saving lighting solutions, especially when coupled with environmental
wins/responsibilities, the overall package is attractive enough to obtain a
comments that there are other common issues with regards to costs and value for
money. For example, there is the need to balance the number and type of
fittings to achieve the required regulatory lighting levels, as stated in the
Dock Regulations, whilst considering typical port ‘obstacles’ like container
stacks, buildings and landside and quayside cranes.
between required lighting output with the optimum number of masts/lamps is an
important factor to consider in order to minimise or avoid the flexible use of
yard stacking and quayside areas,” he adds. “As is the optimisation of a port
layout and balancing the number of masts/lamps whilst considering the cable
look carefully at the lighting levels considered necessary to run a facility to
ensure that the correct lighting levels are being used and over illumination is
being avoided. The opportunities afforded by improved lighting control are also
emerging to reduce lighting output thus saving energy costs when full output is
not required. To this end, port operators are prepared to consider alternative
suppliers for both lighting equipment and the supply of energy.
consideration is generally given to the cost of electricity in the current
economic climate, operators have become more aware of the real link between the
lighting levels required, energy efficient lamps and the cost of electricity,”
says Mr Steele.
safety is another element that port operators must consider. Safety
requirements when dealing with electrical installations need to be taken into
consideration. In addition, port operators should consider access for
maintaining the lights – especially those for high masts.
There is also
the risk of light pollution to take into account. Some locations have strict
controls regarding light pollution and solutions such as Prisma all but
eliminate light pollution by controlling the light directly to the ground with
minimal loss through light pollution. LED lighting by design will provide the
“This can be a
very sensitive issue particularly when there are residential areas close or
adjacent to a port,” says Mr Steele. “It is a matter of growing importance and
there are strong environmental concerns about light spillage, light ‘trespass’
design of the layout, height of masts and selection of lamp fittings is
required to mitigate light pollution. In some circumstances the use of lamp
shades to cut down extraneous upward light spillage may be required.”
So what of the
current trends in port lighting? Terminals are looking at various low cost low
energy lighting solutions. Suppliers are also becoming more prominent in the
offering of their solutions. There are accurate assessments of and
specifications for the required light levels, plus better assessments to make
sure that the correct fittings are used for durability and ease of maintenance.
Add to that lower energy strategies, and an awareness of environmental
requirements to mitigate light pollution, and it's easy to conclude that
today's port lighting products are committed to offering the highest quality,
environmentally friendly solutions and excellent value.
