Ice-class Vessels – New Class Rules by LR

Press Release
Thursday, April 19, 2012

Classification society Lloyd's Register draws on industry experience to issue new rules for stern-first ice-class vessels

Growing commercial opportunities in the far north boost demand for customised shipping solutions

The first dedicated set of rules for stern-first ice-class ships has just been published by Lloyd’s Register, answering demand for technical support as industry continues to explore the potential of polar transportation routes and the new energy reserves in the far north.

The timely release of the rules comes as more and more ships are being ordered with options such as podded propulsion systems and azimuthing thrusters – products that can improve icebreaking capability and reduce resistance -- allowing them to navigate stern first through ice.

"These practical rules are answering a growing demand in the market and include the use of standard operational scenarios to provide designers with a basis for prescriptive rule applications that have been validated with designers and operators of these specialist ships," said Robert Tustin, Lloyd's Register's Technical Manager for New Construction in Asia.

Lloyd’s Register has had a long involvement in the development of this class of ships. Mastera and Tempera – two 106,000 dwt "double-acting" tankers owned by Neste -- were built to its class in 2002 and 2003 at Sumitomo's yard in Japan. The ships were deployed to the Baltic, where they often operate stern first in heavy ice conditions, independent from icebreakers.

Other tankers, such as Sovcomflot’s Mikhael Ulyanov and Kiril Lavrov, were designed and built for operating stern first in ice in the Arctic. These ships, dual classed by Lloyd's Register and the Russian Maritime Register of Shipping, were designed to eventually shuttle crude from the Prirazlomnoye platform in the Pechora Sea to a floating storage and offloading unit moored off Murmansk.

The development of Lloyd's Register's new rules were supported and validated by leading ice-class tanker designers, key regulators and operators.
