Mechanical response: open sea, coast/archipelago, rivers, land

Module 3 of 6

At sea the sequence is usually surveillance, booming where current and wave height allow, and skimming into temporary storage. On the coast and in the archipelago the priority is exclusion booming of bays, bird islands and water intakes with 750–900 mm shoreline booms.

In rivers the current dictates boom angle and anchor points; a boom set square to the flow will fail. On land the task is to stop migration into soil and drains, then collect with sorbents, vacuum and lined buffer pits. Always match the method to the site, not the other way around.

Four panels showing mechanical oil-spill response: booming and skimming at open sea, exclusion booming in a rocky archipelago bay, river booming anchored from the shore, and land recovery with sorbents, a buffer pit and a collection container
