The Galley is a 24-hour working department on-board a cruise vessel. During the course of a day, many thousands of meals must be prepared and delivered to the various on-board restaurants.
Lighting in galleys and pantries should provide a safe working environment by achieving a certain level of light intensity, a good colour rendering and colour temperature. The lighting needs to be reliable and the luminaires must be maintenance-free.
Different areas on the ship require special demands for lighting
As galleys and pantries are hygienic areas, lighting should be specified according to USPH (United States Public Health). To withstand intensive cleaning, they must also have a high IP rating and be made from a chemical-resistant material. High temperatures are often present in these areas. Hot spots are often found in cooking areas and where steam is present. In addition to these requirements, the fixtures must be easy to install, maintenance-free and should provide sufficient illumination with an appropriate colour rendering (CRI).
Important factors when selecting lighting solutions for galleys/pantries:
- Easy to clean.
- Reduced power consumption (high energy efficiency).
- Consider low ceiling heights (isolation and ventilation ducts, lower the height of the stainless steel ceilings).
Easy to clean
The correct design of the luminaire is important in order to ensure easy cleaning to avoid impurities. When using brushes, pipes and sometimes high-pressure cleaners, the luminaires must have a high IP protection rating to withstand these pressures.
Using the correct combination of materials in the luminaire is important in order to ensure robustness and a long operating life. Materials and designs must be be specially selected to withstand possible mechanical impact or damage.
No maintenance and reduced power consumption
An important requirement on-board a cruise 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. 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 cruise vessels with LED lighting will have lower operating costs compared to vessels with conventional luminaires. In addition, the reduced power consumption of LED lighting onboard has a positive impact on the cruise vessel’s Air Conditioning system, as less heat is emitted from the lighting, which means less AC power is needed and fuel consumption is reduced. The initial investment of the LED installation may be higher than a traditional lighting installation, but the reduced energy consumption and lower maintenance costs of LED lighting means that this price difference will be quickly recouped and payback on the investment is recovered quickly.
Low ceiling height
Ducts for ventilation and dust/fume extraction hoods lower the height of the ceiling. The chosen luminaires must therefore fit into these limited spaces.
All lighting products for galleys/pantries should be designed in accordance with marine standards and regulations.
