Oil Spills

”The Full City”

The “Swedish Pump” is the most efficient:

During the clean up operation after the oil spill in Langesund the Salarollpump was used to suck up larger puddles of oil and oil emulsions.

KRAGERÖ: The island Jomfruland in Kragerö community has a shore line of round stones as far as the eye can see, this was unfortunately hit by thick bunker oil when “Full City” run aground on the 31st of July.

This is the first time I have operated this equipment. It is genius. We have pumped with one of these pumps for three days now and recovered around 1300 liter on an area of 30 times 30 meter, says Trond Holten from the North Norwegian response centre. He was in charge of the clean up operation on Jomfruland for the first few days, and directed around 30 soldiers, volunteers from WWF and the local community.

Remote area

A remote area like this can neither be reached by car nor boat. The work to take up several tonnes of oil from this (area from high to low tide) has so far been done by hand. When the little newly baptised “Swedish Pump” was used, as it soon was to be called, the volunteers don’t have to stand in oil up to their ankles and put oil in buckets.

There is a hose put as a loop inside the pump housing. A wheel rotates and compresses the hose so that a negative pressure is created.

The vacuum that occur makes the suction possible. It can pump up stones and soil without any problem, Holten explains. As a matter of fact, the pump can suck up stones up to 35 mm without getting hiccup, and it can easily lap up the thickly floating and nasty smelling bunker oil which is floating in puddles.

Rescued by the Swedes

As the nick name suggests, it is the Swedes that have invented a nice little assistant which can assist in difficult beach clean up operations. The pump is hydraulic, but can be connected to an ordinary petrol, diesel or electric motor.

In Norway Elba AS is selling or renting out the pump. They are one of many suppliers of equipment that enters the track when anaccident of this magnitude occurs. We are renting out the pumps for this operation, and this is the first time they have been used in Norway says Ronny Thoresen at Elba.

Challenge

Holten is in any case very satisfied with the job that the pump does. But in the future the difficult part remains to reach the oil in between all the stones, and to wash the beach clean. No operation is like the other. In Fedje in 2007 it was a different challenge and different coast line. It is during operations one really can learn, says Holten.

Tjörn oil spill

Oil Spills

Tjörn oil spill - The worst Swedish west coast spill in 20 years. Ten Salarollpump Clean up Systems deployed.

900 tons of heavy oil have been cleaned up after coming ashore on the west coast of Sweden following a spill farther out to sea. The Swedish Civil Contingencies Agency and the Swedish Coast Guard were both involved in the operation. At the start of the clean-up operation 600 tons of the thick oil were picked out of the water using vessels with crane and grab. Approximately 300 tons hit the shore line. Approximately 150 tons could be accessed and were cleaned up using large vacuum trucks. The remaining 150 tons were inaccessible to all but compact, light weight equipment. Thus 10 units of the Salarollpump system for clean-up of heavy and polluted oil in remote areas was used for the remaining 150 tons which were inaccessible for bigger equipment. These Salarollpump units were used for two weeks, during which the bad weather made it impossible to work on some days.

Oil Spills

When there were large quantities of heavy oil and little water, the water injection applied on the suction side increased the capacity. This is a separate accessory which can be supplied with the Salarollpump.

Oil Spills

The Salarollpump and a 1 m3 container (IBC) were loaded onto a barge to reach the polluted shallow water areas. Once the container was full, it was transported to a larger vessel and lifted on board with a crane. Oil was pumped up from the beach or from very shallow water areas. Some water was pumped with the oil and the water was separated using the IBC bottom valve. The low pump speed ensures that the oil and water does not mix and separation of water is easy. In areas where there was a lot of oil, pumping was pretty well continuous. An IBC was filled with oil in 30 minutes. After processing of the 900 tons of the recovered spill, 500 tons of clean oil was recovered, i.e. the water content of the emulsion was approx. 45 %.
