There are two basic scenarios for icebreaking support vessels. The first is the delivery of drilling fluids and supplies to drilling units and other development operations. The second is the performance of ice management duties, including continuous icebreaking and ramming of significant features to reduce loads on structures. The tradeoff involved in the decision to employ these vessels as either ice management or supply icebreakers is in power and cargo capacity. The design of the Alaska Class series of vessels has been an endeavor to identify efficient propulsion, structure, and arrangements to reduce the impact of these conflicting requirements.
