Water and Sediment

Last updated 10/5/2016 11:37 AM

The blue sea is a guiding principle for us and we shall contribute to creating a cleaner marine environment. It is equally important to minimise the effect on the water in our local environment and in our facilities. We therefore focus on preventive measures that minimise the risk of emissions to water, but also on fast and effective initiatives if nevertheless an accident was to occur.

”The torpedo” is activated in connection with oil spillages
Despite the fact that there never has been an oil spill in the Oil Port, CMP in Malmö has invested in a unique technology so that it is properly prepared if there was to be an accident. CMP was first in the world to use a technology called Autonomous Surface Vessel (ASV). It is an electrically powered torpedo, which is activated and steered out in the water if a spill was to occur. The torpedo pulls a boom and docks in one of the stations on the other side of the harbour basin. The boom enables a spill to be quickly limited. The Emergency Services previously came by boat, which meant that at worst it could take up to an hour before the boom was in place. Today it takes a maximum of ten minutes. 

Smart handling of fire water
CMP has installed a fire water facility in the Oil Port. If a fire was to occur, this equipment deals with the contaminated fire water in an effective and environmentally sound way. The fire water system is a supplement to CMP’s ordinary surface water system. If there is a fire, all surface water is conveyed directly to the fire water system through an 800 metre long pipe that has been laid in the ground and transports the fire water to a special pool. From the pool the water is then pumped onward to a tank where it is dealt with.

Waste water is collected up
In Northern Harbour in Malmö there is a facility for cleaning containers. The waste water is collected in tanks and the amount of pollutants in the water is measured. This service reduces the environmental impact as fewer containers need to be transported by lorry to be cleaned at other facilities in Skåne. 

Green roofs bind pollutants
The three buildings at the Ocean Quay cruise terminal are all furnished with green roofs. It is a roof covering that consists of live vegetation. These plants both subdue noise pollution and purify rainwater.

Purification of surface water 
In Swede Harbour, various types of dry bulk products are handled that can contaminate surface water.  The surface water in the area is consequently conveyed to a pool that has a lime barrier. This purifies the water through both sedimentation and filtration before it subsequently is released to the harbour basin. 

Contingency measures for emergencies 
An “emergency plate” is located at the container terminal to deal with leaking containers. Placing the container on the plate prevents the leak from contaminating soil or water. Leaking liquids are collected at the emergency plate and dealt with in a closed system. At various locations in the terminals, CMP also has emergency stations with booms and absorbents to rapidly limit the effects of any spills and leaks. 

Hatches protect the harbour basin 
Surface water is conveyed out into the harbour basins via drains in and around the port area. As a precautionary measure, so called MOV hatches are positioned at the quay-edges. If a spill occurs, these hatches are immediately closed, thus preventing contaminated water in the drainage system from entering the harbour basin.

Controlled hull cleaning
Over time, a hull is affected by fouling – for example, algae and barnacles. The fouling increases the resistance between the hull and the water and hence, increases fuel consumption. CMP allows visiting ships to clean their  hulls when in Copenhagen and Malmö. The organic material is brushed off the hull and the waste water from the cleaning process is filtered and the organic waste is dealt with in an environmentally sound way. Hull cleaning contributes to reducing the use of toxic antifouling treatments, which are a more environmentally damaging method of preventing fouling.
