There are very few icebreakers in the world and most of them are very old. For this reason, not many companies have the knowledge or skills to build an icebreaker. In addition, when a new icebreaker is built, it is important that it meets the very latest standards and is able to remain in operation for at least 50 years. There are no shipyards with finished drawings that are ready to start construction. When the decision is made to commission a new icebreaker, the process takes around five years to complete. The first two years are spent on ordering and designing the vessel and the next three on building it.
