The pumproom is often a dirty, oily environment that contains the largest concentration of pipelines of any space within the ship. The pumproom typically contains a number of potential ignition sources. Leakage of volatile product from any part of this system could lead to the rapid generation of a flammable atmosphere. In addition, ship operations require the pumproom to be routinely entered by personnel, who will often need to use tools.
Different areas on a ship have particular demands on lighting
Special requirements on lighting installed in pump rooms are that it is both: explosion-proof and resistant against chemical gases. In addition, the fixtures must be easy to install, maintenance-free and should provide sufficient light intensity with appropriate colour rendering (CRI) to avoid mistakes.
Important factors when selecting lighting solutions for pump rooms:
- No maintenance and reduced power consumption (high energy efficiency).
- Different mounting options.
- Solid and impact-resistant.
No maintenance and reduced power consumption
An important requirement onboard a marine vessel is to install luminaires that are virtually maintenance-free. This reduces or eliminates the labour costs primarily associated with the maintenance, servicing and replacement of luminaires in difficult-to-reach locations with either poor access or often no access at all. The luminaires should consume as little energy as possible in order to reduce the size of power generators, save energy and minimise pollution. The efficiency and life span of LED lighting continues to improve. LED luminaires are virtually maintenance-free, which means that vessels with LED lighting will have lower operating costs compared to vessels with conventional luminaires. The initial investment of the LED installation may be higher than a traditional lighting installation, but the LED’s reduced energy consumption and lower maintenance costs means that this price difference will be quickly recouped and payback on the investment is recovered quickly.
Different mounting options
As there are many different mounting scenarios onboard a vessel, the luminaires should provide a range of options to allow the same fixture to be used in all cases. This means a wide range of brackets should be available for flexible mounting options and distances. Particularly in pump rooms, it is difficult to install lighting due to the high concentration of pipes present, which needs careful consideration.
As soon as luminaires are installed in areas where potentially explosive gases can occur, the installed light fittings must be certified according to the relevant explosion class and hazardous zone for that area.
Solid and impact-resistant
Using the correct combination of materials in the luminaire is important in order to ensure robustness and a long operating life. Materials and design have to be specially selected to withstand possible mechanical damages. A wide range of ambient temperatures is also an important demand. Marine vessels must be able to navigate around the world – from Arctic areas down to -40°C or lower, to tropical areas at +50°C. Ideally, the light output and light quality should be consistent in all temperature bands. The lighting illumination level should have an average of 200 lux.
We always recommend the use of a marine-approved lighting product in pump rooms.
