PREVCO Subsea, LLC is a subsea engineering consultancy, specializing in submersible pressure vessels, instrumentation housings, junction boxes, pressure relief valves and other subsea enclosures and accessories, is increasing their Pressure testing capabilities. Following a successful move in April 2014 into a 30,000 sq. ft. facility, the Prevco team are already expanding the new building to add a new 15,000 psi hydrostatic chamber which had to be lifted in through the roof. The installation took place last December and involved the heavy vessel being lifted by two cranes one, a  97-ton crane and a second, 297-ton crane, one of the largest cranes available in the area, maneuvered the vessel into a vertical position for lifting.  The vessel was raised above the building and lowered through a hole in the roof, finally coming to rest on a specially designed mounting stand.
The new vessel joins two other test tanks and increases the in-house pressure testing capability and services offered to outside companies needing pressure testing.
