ICE TRIALS OF ILS DESIGNED
ICE BREAKER TOBOY
T
he ice trials of the ILS designed ice breaker Toboy – which was
delivered at the end of 2008 to Lukoil from the Singaporean
shipyard Keppel Singmarine – were carried out in Kara sea in midsommer 2009. The trials were managed by ILS, propulsion power
measurements were carried out by VTT, the ice data and measurements by AARI. The owners and Russian Maritime Register of
Shipping were supervising the tests. Experts from Keppel Singmarine, Keppel Norway, Wärtsilä and Steerprop were also onboard.
The tests were carried out in accordance with a test programme including level ice performance tests in various ice thicknesses (a 1.4m thick level ice field was found) ahead an astern,
turning, ridge penetration, breaking out of channel ahead and
astern, turning in spot and channel widening tests. Toboy cleared
well the tests and all participants could confirm that the vessel
fulfilled the requirements with good margin.
The other vessel, ice breaker Varandey will be tested later this year. ■
