The design of the current Subsalve
lift bag had its beginnings in 1977 when the company was chosen by the US Navy
to produce a range of standard open and closed bags. Our continued work on cutting
edge projects allowed for the development of our unique lift bag shape and the
high-performance products in the Subsalve line today. Subsalve designs have evolved
with the advancement of technology and materials and will continue to rise to
the needs of our diverse clientele. We are committed to the tradition of research,
development and comprehensive hands-on testing that has made the Subsalve company
the clear leader in underwater lift bags.

Subsalve lift bags used in installation of offshore pipelines in the Gulf
and North Sea
1979 Contracted by the Naval
Ocean Systems Center to create deep ocean lift bag.
The objective was to design a bag with maximum lift to weight ratio, offering
maximum buoyancy with minimum bag weight.
ratio, offering maximum buoyancy with minimum bag weight.
Subsalve also designed an innovative pressure release valve, which allowed for
the venting of expanding air. This project set a new standard for lift bags and
created a bag capable of lifting 12 metric tons.

Subsalve was asked to develop and participate in underwater bomb recovery
After the Oklahoma
City Bombing, it was determined that agents needed to be trained in underwater
bomb recovery. The president of Subsalve, Richard Fryburg, was asked to develop
a program to train FBI and other agents. Subsalve also developed a new product,
the Unexploded Bomb Recovery System, and became the only approved supplier of
Hurricane Opal again, Subsalve bags used in 100s of yacht recoveries.
