Noise pollution can be a health hazard, both for staff and for those living nearby. We therefore put a lot of effort into reducing the noise from our operations. Some facilities have been relocated further out towards the sea. In other cases, we have invested in technical solutions to minimise disturbances. In addition, we regularly measure and follow up on the noise levels.
Relocating terminals reduces noise
In both Copenhagen and Malmö we have gradually moved operations further out from the city centre. This has had a positive effect on the perceived noise levels. In Copenhagen the new Ocean Quay cruise terminal is located further out towards the sea. In Malmö, moving the Container and RoRo terminals to Norra Hamnen resulted in rerouting the bulk of heavy lorries away from the city centre. Another benefit of the move is that ships in Norra Hamnen can now be loaded and unloaded much faster. This reduces the time in which they emit noise pollution. In Malmö the scrap metal operation has also been moved further away from public buildings. Instead the least disruptive activity – the car terminal – is located closest to the city.
Well below the limit values
CMP:s operations in Malmö have now been shown to not exceed the limit values in the districts that are closest to the port – a noise pollution simulation model has been used based on measurements from all kinds of operations in the port, ships, machinery, loading and unloading. The measurements have been entered into a database and are reflected on a chart in the model that shows how levels of noise pollution is distributed. The results show that the operations give rise to lower levels of noise pollution than the limit value in the environmental permit.
Green roofs cut noise
The three terminal buildings at Ocean Quay in Copenhagen are all furnished with so-called green roofs. This roof covering consists of live vegetation, which subdues noise pollution and absorbs air pollution and rainwater.
Rubber mats that reduce noise
Rubber mats are used to muffle the sound within RoRo. The background is that the ramps that the ships lower when unloading and loading are made of metal. When the lorries drive on and off the ships via this ramp it makes noise. A rubber mat is now placed between the ramps and the entrances at the RoRo terminal. Furthermore, the concrete on-ramps at the facility are designed to reduce noise pollution, both through the design and via the special concrete used in the construction.
Quieter vehicles and working machines
Investing in modern, new vehicles and machinery reduces noise pollution. Electric cars that are almost silent are currently tested throughout the operation. Increasing numbers of working machines are also leased from external suppliers. This gives us access to new and more environmentally sound technologies that also are quieter.
