Projects
Heger Dry Dock has participated in the design of numerous floating dry docks, vessel transfer systems and launching methods. We are also regularly asked to prepare blocking plans, pumping plans and or develop procedures for drydocking difficult or unusual vessels.

12,000 Ton Capacity Transfer System for Existing Floating Dock
In 2004 VT Halter in Pascagoula Mississippi needed to launch the 12,000 ton vessel JEAN ANN which they were constructing.
HEGER provided complete design drawings and specifications for transfer tracks on shore and on the floating dock, roller system and transfer cars. We inspected and analyzed the existing floating dock structure’s capability to support transfer loads and recommended strengthening. We provided loading on concrete slab for review by others. We developed transfer procedures, operational limits and pumping plan for the transfer. We developed the procedure for installing transfer tracks and cars and step by step procedure for transfer of the vessel’s weight from building blocks to the transfer cars. We directed the ballasting of the dock during actual transfer.
The JEAN ANN was successfully transferred and launched in 2004.
