A full-scale test propulsion measurement program was performed on the Fednav owned UMIAK I, a 31500 DWT bulk carrier classed by Det Norske Veritas. The propulsion machinery is distinguishable; consisting of the combination of a large-bore electronically controlled two-stroke diesel engine directly driving the large controllable pitch propeller mounted in a nozzle. The objectives of the research were to better understand the quantification of the loads caused by interaction between propeller blades and ice, and the corresponding dynamic responses through the shaft line and into the main engine, and to assess compliance with the IACS Polar Class design code.
在俄罗斯联邦海军拥有的UMIAK I号散货船上进行了全面的推进测试，UMIAK I号是挪威船级社(Det Norske Veritas)的一艘31500载重吨散货船。推进机械是可分辨的;由一台大口径电控二冲程柴油机直接驱动安装在喷嘴上的大可调螺距螺旋桨组成。研究的目的是更好地了解螺旋桨叶片与冰之间相互作用引起的载荷的量化，以及相应的通过轴线进入主机的动态响应，并评估是否符合IACS极地级设计规范。
