Zone of No Save Analysis for the British Columbia Coast

Nuka Research was commissioned by Clear Seas Centre for Responsible Marine Shipping to analyze how the location and availability of Emergency Tow Vessels (ETVs) or rescue tugs might influence the potential for a disabled vessel to drift aground along the west coast of Canada. To do this, Nuka Research created a computer model to calculate the probability of a disabled vessel drifting ashore due to wind and wave forces. Different probability zones were identified. 

Nuka Research compared how the probability zones changed depending on the assumed location and speed of ETV based along the British Columbia coast. The results of these scenarios can inform risk mitigation decisions such as where to station ETVs, or other proactive vessel management measures aimed at reducing the risks associated with drift groundings along the Pacific coast.
