The Nautical Institute has put together a second edition of its popular ice operations textbook.

Operating ships within any ice regime requires knowledge, skills and awareness beyond that of many mariners, particularly when sailing in waters affected by hard multi-year and glacial ice. Should things go wrong, little assistance is available in polar regions, so mariners must be self-sufficient.

Captain Duke Snider FNI brings his extensive experience in polar shipping and as a highly qualified ice navigator to describe the human, technical, environmental and operational challenges of transiting polar seas. This new edition has been updated to take account of IMO's Polar Code, which came into force in 2017.

During the month of April, Polar Ship Operations - Second Edition is available at a discounted price of £30 (usually £50). To place an order, please email: pubs.admin@nautinst.org
