For the refit of Cargo Vessel Ocean Reliance (ex Tokai), TBV Marine Systems has re-designed their concept for dumbwaiters. The famous TBV – backbone – principle was requested for this refit, but there was no top entrance to the shaft. In good cooperating with the shipyard (Dunston Shiprepairs Ltd.), the backbone was designed in three separated plug-and-play parts, but still with integrated TBV Marine systems electro-hydraulic (2:1) chain drive.
This technical solution it was possible to do the installation of this three stops dumbwaiter, including testing, commissioning etc. in just four days. Again was proven that the TBV backbone principle will help to reduce installation time on board and with very low involvement of the shipyard.
