The “corridor” system. Two parallel floating booms ended by frames, supporting the oil release arrangement at the entrance (bottom right) and the dispersant spray boom at the end (top right). This system has been implemented in 2005, during the French sea trials Depol05, which testing program has been unfortunately stopped prematurely due to a technical incident on the main ship. However, the corridor system proved to be promising: such testing procedure allows to run an important number of comparative tests with limited amount of oil. while working with highly controlled application conditions, especially regarding the DOR (Merlin 2008).
