See More Floating Dry Dock Design

In 2002, HEGER designed a sectional-type steel floating drydock for METRO MACHINE CORPORATION to be operated in Norfolk, Virginia. The shipyard is now owned by GENERAL DYNAMICS – NASSCO.

The dock was designed to meet the requirements of the US Navy’s MIL-STD 1625C and the American Bureau of Shipping for lifting vessels displacing up to 40,000 long tons.

The dock’s design vessels were considered to be the largest US Navy surface ships including the LHD/LHA hulls, LPD-17, CG-47 and DDG-51 class vessels.
