Koseq sweeping arm has proven to be the best tool for recovering oil from the sea. This is demonstrated and proved by the independent EMSA document, which reports the effectiveness of various oil recovery equipment used during the prestige spill. In this case, the Koseq sweeping arms were the most effective oil recovery equipment used to recover oil. The rigid sweeping arm is the result of years of development in this field. It has been used and has successfully operated during the largest most recent oil spills , including the disasters with the Erika, the Sea Empress and The Prestige.

Oil spills can cause a large amount of damage. In the past there has been a number of accidents, where large quantities of oil have been spilled. This inspired our director Mr. Kampers to develop a way to remove oil from the water surface. Development of the rigid sweeping arm began over thirty years ago and took place in cooperation with the Dutch Coast Guard and TNO.

The goal was to produce a simple but effective tool that could recover large quantities of oil. The rigid sweeping arm is the result of years of development in this field. It has been used and has successfully operated during the largest most recent oil spills , including the disasters with the Erika, the Sea Empress and The Prestige.

Following the Prestige disaster in 2002, and in light of the excellent performance of the rigid sweeping arms during this oil spill disaster , the demand for the Koseq rigid sweeping arms dramatically increased Prior to the Prestige disaster, most of the rigid sweeping arms were used by the Dutch Coast Guard, but, following this event, rising international demand led to Kampers forming a new company: Koseq.

Mechanical containment or recovery is the primary line of defence against oil spills. This method is by far the most desirable, since it does not have detrimental effects on other methods and it prevents further damage before oil reaches the shore. Other methods, like chemical dispersion or insitu burning are not advisable because of the toxic residues that remain in the environment.

In cooperation with Rijkswaterstaat (the Dutch Ministry of Transport, Public Works and Water Management) and T.N.O. (Dutch Organization for Applied Scientific Research) we began developing the rigid sweeping arm over thirty years ago.

The aims were to develop a device that: :

  • Mechanically recovered large quantities of spilled oil in a short amount of time.
  • Operated effectively during bad weather conditions and rough seas.
  • A reliable system.

These demands resulted, after a long period of development, in a free floating rigid arm to be pulled directly next to a vessel. When the vessel moves forward, oil will be guided between the ships hull and the rigid sweeping arm to the oil collection chamber in the sweeping arm. The oil/water mixture is then pumped on board the vessel through an oil tranfer pump.

On board the vessel, the oil/water mixture is separated through the difference in specific weight. Subsequently, the water can be pumped overboard. The recovery of spilled oil can continue until the tanks on board the vessel are completely filled with oil.
