Multipurpose triple-decker heavy-lift class sized to fit the Great Lakes-St. Lawrence Seaway, with two Liebherr LS250 cranes lifting up to 500 mt combined.

Description

The LakerMax class is a series of multipurpose triple-decker heavy-lift vessels owned by Briese Schiffahrt and operated by BBC Chartering. Their dimensions are maxed out to still fit the locks and bridges of the Great Lakes-St. Lawrence Seaway. The first unit, BBC LEER, joined the fleet in May 2024, and BBC HOUSTON was the first to transit into the Great Lakes, in 2025. Fifteen vessels were ordered initially, and six more are firmly ordered.
