A Marine Evacuation System (MES), consisting of a slide or chute where passengers can evacuate straight into waiting life rafts, can often be found on modern high speed crafts and passenger ships, where weight, space and evacuation times must be kept to a minimum. For the first time, a similar system has now also been developed for Special Purpose Ships (SPS). A close relationship between Norwegian-based Brude Safety AS and Ulstein Design has lead to this new type of space saving MES, designed to fit Special Purpose Ships, such as Offshore Support Vessels (OSVs).
