The Rigid sweeping arms offer an easy, fast and safe solution for offshore oil recovery in severe weather conditions. It has proven itself in many incidents like the Erika, the Prestige and BP-Macondo spills.
Rigid sweeping arms are steel, free floating constructions that are pulled alongside a vessel. Each arm has built-in pontoons on both ends, giving it floating capabilities.
When the vessel is moving forward, the oil will accumulate in front of the arms. The oil is guided between rigid sweeping arms and the ship’s hull to the built-in oil collection chamber. In this chamber a skimmer and pump is placed that pumps the oil into the oil recovery tank on board of the ship. Standard a weir skimmer is mounted. This can within minutes be exchanged for a brush- or disk skimmer module.
Koseq delivers a complete set of equipment. Besides the rigid sweeping arms the system consists of dedicated sweeping arm handling cranes and hydraulic power packs, as well as booms and other oil recovery equipment to be used in conjunction with sweeping arms or independently. The cranes are specially designed to secure quick and save deployment of the sweeping arms. The power packs can be electrical or diesel driven, and can be executed for “normal” use, or for use in Zone II areas.
