SUMMARY:Conclusions from the 2022 VLSFO Oil Spill on the Swedish West Coas
 t
DESCRIPTION:Paper\n\nJonas Pålsson (Swedish Agency for Marine and Water Ma
 nagement), Kristin Magnusson and Mikael Dahl (IVL Swedish Environmental Re
 search Institute), Malin Holm-Roos (Swedish Coast Guard), and Maria Granbe
 rg (IVL Swedish Environmental Research Institute)\n\nOn 13th of April 2022
 , a ship-to-ship fuel transfer operation off the Swedish West coast result
 ed in a spill of VLSFO into the ocean. The spill traveled just below the s
 urface and was invisible to the surveillance of the Swedish Coast Guard, u
 ntil it ended up on the coast a day later, spreading around the archipelag
 o outside Gothenburg and North of it. The Swedish Coast Guard estimates th
 at around 1,000 L of oil were collected when the response operation was co
 ncluded. This is one of the first VLSFO spills in temperate waters. The be
 havior of this VLSFO spill was different to normal HFO spills. The oil clu
 stered together into smaller and very sticky lumps to a larger degree, the
 re was little to no oil sheen visible, and the oil was difficult to remove
  from the rocky shores and the abundance of algae on the coast. An environ
 mental assessment was performed after sampling on the 3rd of May. The biol
 ogical samples usually target blue mussels (Mytilus edulis), but they have
  become rare on the Swedish West coast and the invasive Pacific oyster (Ma
 gallana gigas) was instead sampled together with algae and sediment. Resul
 ts showed increased levels of benzo(a)pyrene in the oysters, but no other 
 thresholds were exceeded. Since the oysters are eaten, there is a need to 
 develop guidelines and thresholds of hydrocarbons for human consumption, f
 or which none exists in Sweden today. In order to make informed response d
 ecisions, more knowledge and research on the environmental impact of these
  new fuels are needed.\n\nTag: Preparedness\n\nSession Chair: Will Griffit
