3. Optimum W2W Vessel Capability Matrix
When considering operations, it is essential that the emergency response plan including required response times are taken into account.
All vessels considered in these matrices are mono-hull, longer than 24m and greater than 300GRT.
‘Restricted’ refers to the relative ease of access to the point of embarkation.
Poor prevailing conditions = Average Wave Height >1.5 m/Sea State >3/Wind speed >10kts/Visibility <Moderate/ Environmental Vector >2kts
Poor prevailing conditions = Average Wave Height >1.5 m/Sea State >3/Wind speed >10kts/Visibility <Moderate/ Environmental Vector >2kts
Benign prevailing conditions = Average Wave Height <1.5 m/Sea State <3/Wind speed <10kts/Visibility >Moderate/ Environmental Vector <2kts
Benign prevailing conditions = Average Wave Height <1.5 m/Sea State <3/Wind speed <10kts/Visibility >Moderate/ Environmental Vector <2kts
