Paper No. 25—"Full-Scale Ice- breaking Tests of the USCGC

Katmai Bay" by G.P. Vance, A.S.

Gracewski and M.J. Goodwin.

SYNOPSIS: This paper describes the full-scale icebreaking tests conducted on the USCGC Katmai

Bay, the first of a new class of

USCG icebreaking tugs. Analysis of the data indicates that the vessel could penetrate up to 22 inches of homogeneous sheet ice with 3 inches of snow cover and up to 48 inches of brash ice. The vessel has an installed bubbler system and a low friction coating.

This paper describes the tests that were conducted, the instru- mentation utilized and an analy- sis of the results.

Paper No. 26—"Ice Effects and

Ship Performance Data Gather- ing System on Board the Ice- breaking Bulk Carrier M.V. Arc- tic" by J.D. Hearnshaw, J.G. Ger- man, A. Benjamin, J. Stirling and

P. Timonin.

SYNOPSIS: The decision to pro- vide a permanently installed in- strumentation system aboard the ice-strengthened cargo vessel

M.V. Arctic and to gather ice- performance data over a number of Arctic shipping seasons, was taken by Transport Canada in 1977. This paper describes the evolution of the scientific evalu- ation program, the development, details and installation in the ship of an instrumentation sys- tem, the data collection under- taken and the results of data an- alysis achieved to this point in the five-year program.
