Abstract

The IMO's International Code for Ships Operating in Polar Waters (Polar Code) entered in to force on 1 January 2017 and provides, for the first time, an international regulatory framework for ships operating in Polar waters. In addition to technical regulations, the Polar Code requires that the Polar Ship Certificate should reference a methodology to assess operational capabilities and limitations in ice: essentially setting operational limitations for the specific ship navigating in Polar waters. The Polar Operational Limit Assessment Risk Indexing System (POLARIS) has been developed as an acceptable methodology for providing guidance on the operational limitations in ice of ships assigned different ice classes and has been directly referenced by the IMO in the Polar Code. The system was developed as a collaborative effort, drawing on operational and regulatory experience from industry and national administrations with experience in setting navigational limitations for ice covered waters. This paper presents the technical background behind the system and supporting information on its practical use both as a voyage planning tool and as real-time guidance on assessing ice regimes ahead of the ship. Validation of the system in the context of other existing regulatory requirements is discussed. The limitations of the system are explored and commentary and proposals are provided on recommended future enhancements.
评估风险和确定船舶在冰上的操作限制
国际海事组织的《极地水域船舶作业国际规则》(极地规则)于2017年1月1日生效,首次为极地水域船舶作业提供了一个国际监管框架。除技术法规外,《极地规则》要求极地船舶证书应参考一种评估冰上作业能力和限制的方法:本质上是为在极地水域航行的特定船舶设定作业限制。极地作业极限评估风险索引系统(POLARIS)已被开发为一种可接受的方法,为分配不同冰级的船舶提供关于冰的作业限制的指导,并已被国际海事组织直接引用在极地规则中。该系统的开发是一项合作努力,借鉴了行业和国家管理部门的操作和监管经验,并具有在冰覆盖水域设置航行限制的经验。本文介绍了该系统背后的技术背景和有关其作为航行规划工具和作为评估船舶前方冰况的实时指导的实际使用的支持信息。讨论了在其他现有法规要求的背景下系统的验证。探讨了该系统的局限性,并对建议的未来改进提供了评论和建议。
