Mississippi (US) On 25th July 2016, near Lake Grand Ecaille in Barataria Bay (Plaquemines Parish, Louisiana, US), a crude oil leak occurred from an abandoned flow line (previously operated by Hilcorp Energy) in Lake Washington oil field. The operator estimated that 16 m3 of crude oil, which had been remaining in the pipeline, had been released into the surrounding marshland. According to the Louisiana Oystermen Association, which filed a lawsuit following this spill, the leak resulted from damage to the pipeline during prop-washing operations, which involve mechanically scouring and widening channels for navigation using propulsion devices (propellers, turbines, etc.)1. To our knowledge, this hypothesis has not been officially confirmed either by the authorities or the operator. The spill response was placed under the supervision of the US Coast Guard (USCG), which coordinated, within a Unified Command, representatives of the entities involved, from both the private and public sectors (relevant agencies and administrations, including the National Oceanic and Atmospheric Administration (NOAA), the Louisiana Oil Spill Coordinators Office (LOSCO) and the Louisiana Department of Wildlife and Fisheries (LDWF)). USCG aircraft based in New Orleans were mobilised in order to assess the spread of the spill, which rapidly affected an July 2016: Drift and spread of a crude oil spill from area of over 2,000 hectares (8 square miles) in Barataria Bay, an abandoned flow line (Barataria Bay, Louisiana) including areas of coastal marshland vegetation. (Source: USCG) The spill response operations, conducted by a private spill response organisation (Environmental Safety & Health) contracted by the operator, involved the mobilisation, the following day, of 2 specialised containment and recovery vessels, as well as more than 900 m of containment boom, lined with sorbent booms, laid at the edge of the marsh to protect the vegetation and contain pockets of crude oil driven by the currents. Four days after the spill, actions (still in progress at the time of writing) resulted in the recovery at sea 3 26/7/2016: Aerial view of the spread of the spill of 1 to 2 m of a water/oil mixture and the collection of around from the Hilcorp Energy pipe in the marshland of 250 bags of oiled solids (mainly sorbents) according to the Barataria Bay (Source: USCG) USCG. Although this was a relatively small spill, it nevertheless illustrated the difficulties raised by the complexity of accessing a site (channels, meanders, streams, etc.) in coastal marshes, in terms of setting up (and the efficiency of) containment, protection and clean-up operations,
