Design of an Ice Strengthened Lifeboat

Abstract

This paper presents a practical design of an ice capable TEMPSC that has been developed to the prototype design stage. Designated the Ice- Strengthened Lifeboat (ISL), it is designed to mitigate the risk of damage or loss, due to crushing by ice, during evacuation from offshore installations or vessels in ice covered waters. The ISL design combines novel hull shape features that helps escape from converging, high freeboard ice floes, with an ice-strengthened composite shell that resists the ice loads. No existing TEMPSC has solutions addressing these issues.
