Whether the aim is to rapidly remove all or some of a substance spilt at sea, inshore, in an estuary, a harbour or in continental waters, or to collect pollutant which has been remobilised following clean-up operations on the shoreline (rocks, infrastructures, etc.), the use of skimmers is extremely common practice in spill response operations. It is therefore important to have equipment which has been selected, purchased, tried and tested in advance, as part of a response planning and preparedness effort, in order to determine the performances of these skimmers and the relevant ancillary equipment, in termes of deployment and expected efficiency.
This guide presents Cedre's knowledge in this field, both in terms of equipment and its use. Based on the information provided and the many illustrations, readers will be able to make informed decisions on the most appropriate equipment and systems for the situation with which they are liable to be confronted, as well as to assess their relevance during exercises or training courses.
This guide mainly targets oil site personnel, res-cue and protection services, fire fighters, person-nel from local authorities' technical services and, more generally, all personnel liable to be involved in the response to a spill in surface waters (off-shore, inshore, rivers, lakes, etc.).
