Vestdavit wins deal for US Navy ESB pair

Bergen-based Vestdavit has secured a contract to deliver “advanced” motion-compensated davits to the US Navy, following orders placed with Vestdavit Inc. by General Dynamics NASSCO to equip two expeditionary sea base (ESB) ships.

The US shipbuilder’s San Diego yard will deliver ESB 6 and ESB 7, the latest in a series of ships which act as mobile sea bases to support mine countermeasure, counter-piracy, disaster-relief, crisis-response and other operations.

For the latest US Navy contract, Vestdavit will supply one 2TDB-7000-type davit for each of the new ESB vessels. With a safe working load of 14,000 kilograms, the high-performance davit can handle boats of varying size and weight, including seven- and 11-metre rigid-hulled inflatable boats and the combatant craft assault. The first davit system is due for delivery to ESB 6 in early 2021.

“ESB ships are built to support the US Navy on critical and potentially hazardous missions, so they need highly flexible and responsive marine davits,” Rolf Andreas Wigand, Vestdavit Managing Director, said.

“The 2TDB-7000 type will allow safe operation in much higher sea states than has been possible for the davits used on any previous ESB vessels.”

Wigand explained that the hydraulically operated overhead telescopic davits can function in both single- and dual-point configuration, with the latter mode enabling synchronised movement of the two davit arms. They also include dual independent self-levelling winches that offer hoisting/lowering speeds of up to 40m/min, an anti-pendulation system and an automatic wire hauler and shock absorbers on each arm – among other features.
