This guide addresses the aspects of contingency planning that are relevant to the liquefied gas carrier and provides recommended crew responses to emergency situations that cause ship damage. The basics covered in this guide will be common to all users. A good deal of the information has been collated from contingency planning formulated by several liquefied gas industry operating managements.
