VB-10,000 Deepwater Contruction Capabilities
US Flagged/ABS Class
The VB-10,000 is a US flagged, Jones Act compliant heavy lift construction vessel which can offer several unique capabilities for deepwater projects. The vessel is classed by ABS as a Maltese Cross A1 Barge HLDK DPS-3 (twin hull construction vessel). The vessel has eight retractable, azimuthing thrusters.
Large Open Moon Pool
As a catamaran vessel the VB-10,000 provides a very large moon pool (160 feet of open clearance between the hulls) for lifting and lowering operations. Transport barges and supply vessels can deliver the components to be lifted directly under the gantries and lifting hoists simplifying hook-up and set-down.
The VB-10,000 has four main lift hoists, four auxiliary hoists and multiple rigging support hoists. The main hoists can be reconfigured as required to provide a wide range of lifting and lowering capacities at varying water depths. The vessel has four 1500-ton capacity heavy lift blocks rated for continuous underwater service. The main and auxiliary hoists are synchronized via the main PLC lifting control system, and direct in-lined electronic load monitoring is provided for the main and auxiliary hoists (for any line part configuration).
Riser retrieval and hand-off
The lift gantries can support multiple work decks and packages for various specialized construction activities. The figure below shows the vessel rigged for deepwater pipelay/riser retrieval and hand-off.
Integrated VB group services
The Versabar Group can provide multiple support services which can be integrated with the VB-10,000 operations to provide turnkey deepwater construction operations. Specifically, our high capability fabrication facilities can fabricate multiple subsea hardware components including jumpers, manifolds, PLETS, PLEMS and suction piles. As the established provider of platform based riser hand-off and pull-in equipment (winch and chain jack systems) Versabar can provide a one-stop shop for the retrieval and installation of pre-laid flowlines and risers.
