Over forty years ago Koseq started in the oil recovery market by developing the rigid sweeping arm. It was, and still is, a different solution than most other stationary equipment.

The increased transport of oil in the 1960s and 70s led to some major incidents where large amounts of oil polluted waters and coasts. These incidents, and the lack of proper equipment to recover spilled oil, lead to the start the development of the rigid sweeping arm. The goal was to produce a reliable and effective tool, capable of removing large quantities of oil at sea under severe circumstances. In cooperation with Rijkswaterstaat (the Dutch Ministry of Transport, Public Works and Water Management) and T.N.O.(Dutch Organization for Applied Scientific Research) the rigid sweeping arm was developed over forty years ago.

First named Doseq and later known as Koseq, sweeping arm systems were built and delivered to the coast guards of the Netherlands, Germany, Spain, Turkey, EMSA, and US response and salvage companies including international dredging companies and local authorities. Some of these systems are permanently installed on vessels, other systems are mobile units, stored ashore and ready for immediate use by appointed and dedicated oil recovery vessels.

Over the years, the Koseq Rigid Sweeping Arm Systems were successfully used to recover many large and small oil spills. These arms are able to perform in harsh sea conditions and have proven reliability and efficiency during oil recovery operations such as disasters with the Prestige, Sea Empress, Erika, Gulf War, Gulf of Mexico and others.
