Seaspan developed and built this Prototype Block to ensure that our production teams are fully prepared to cut steel on the Polar Icebreaker in late 2024. The process of building the Prototype Block resulted in learnings in three key areas: improvements in design for manufacturing; testing of new equipment, processes and procedures; and validation of first-time quality in manufacturing to form and weld this new, specialized and thicker steel. "Having the opportunity for our engineering and production teams to work collaboratively to construct this Prototype Block very early in the design process was beneficial not only to Seaspan, but also to our customer and our cross-county supply chain. We are all working toward the same goal of delivering the Polar Icebreaker to the Canadian Coast Guard.
