Layer 2: Evasion
If possible, sailing through dangerous areas should be avoided. If timely informed about a known hazard, such as a pirate activities or an incident at sea, it is often best to take a detour and stay well away, or transfer the cargo to a well risk mitigated vessel.
Once a dangerous situation has been detected, the vessel has to keep well clear of the threat by evasive manoeuvres. Thereto, continuous observation and analysis of the situation is needed.
