Pontoon Assembly and Utilization: Pontoon Dry Dock

Training film on how to construct a Pontoon Dry Dock. The Navy Lighterage pontoon (NLP) was a type of pontoon developed in World War II by Capt. John N. Laycock Civil Engineer Corps (CEC) and used by United States Navy Construction Battalions (Seabees)[1] on invasion beaches and shallow harbors or harbors where the facilities had been destroyed or did not exist. It was referred to as the Seabee's "magic box". It was Lego-like system of pre-cut pre-drilled angle iron and steel plate. It was first assembled into individual boxes that were joined in multiples to construct docks, causeways, barges, dry docks, floating cranes, marine railways or whatever was needed. 1950, MN 6826c Film digitization made possible through a generous donation from the Navy Seabee Foundation whose support enables the U.S. Navy Seabee Museum to preserve, protect, and share Seabee history.
