WCMRC maintains a growing fleet of emergency response vessels, including custom-built oil spill response vessels, deck and tank barges, landing craft, skiffs and workboats.
Barges are used in spill response to transport equipment and to store recovered oil from a spill. Large barges can act as operating platforms and form forward operating bases in remote locations.
