ABSTRACT:
An improved polyethylene float drum for marine structures has a preformed polystyrene core which is configured to dimensionally conform to the interior surfaces of the polyethylene walls of the drum. Because the preformed core fills the entire enclosure of the float drum, a dimensionally controlled float drum is provided with superior strength characteristics.
