Marine pollution Classification (MARPOL Annex II)
Category Description
Y Noxious Liquid Substances which, if discharged into the sea from tank cleaning or deballasting operations, are deemed to present a hazard to either marine resources or human health or cause harm to amenities or other legitimate uses of the sea and therefore justify a limitation on the quality and quantity of the discharge into the marine environment.

  About the project

HNS-MS is a decision-support tool that Belgian and French maritime authorities as well as coastguard stations can activate in order to forecast the drift, fate and behavior of acute marine pollution by Harmful Noxious Substances (HNS) accidentally released in the marine system.
