Pushing on to Brazil
Two RApide 4600 push boats built by Turkey’s UZMAR Shipyard for Hidrovias do Brazil S.A. have left the yard for their maiden voyage to Brazil.
After successfully delivering eight diesel-electric shallow draft river push boats in 2014 - 2015; UZMAR Shipyard, also known as “Workboat and Tug Factory” of Turkey, was awarded a contract for the additional two sister vessels with modernised design in 2021.
The new push boats are specifically designed to push barge convoys; total length 299m, breadth 53m and 48 tonnes max deadweight on inland waterways. They will operate along rivers in northern Brazil, often in remote locations and in challenging operating conditions.
The Robert Allan Ltd. designed RApide 4600 series are diesel-electric triple-screw, shallow-draft vessels driven by three azimuth drive propellers in tunnels. The vessels are 45.6m LOA, 16.5m beam, with a bollard pull of 65 tonnes.
Hull, machinery casing, deckhouse, wheelhouse, and funnels are all welded steel construction and the hull form is designed to incorporate a tunnel stern to permit the fitting of large-diameter propeller L- drive units maximising propulsive efficiency in the shallow water environment.
The diesel-electric power generation system comprises three resiliently mounted medium-speed generator sets. The engines are designed to operate on either Heavy Fuel Oil (HFO) or Marine Gas Oil (MGO). The shallow draft constraint dictates that the utmost attention is going to be paid to weight control throughout the design and construction of every aspect of the vessel.
In order to meet demands for manoeuvrability, maximized fuel economy, and comply with the crash stop requirement, extensive analysis was carried out by Robert Allan Ltd. As a result, the hull shape, tunnel geometry, and propulsive components have been optimised for those specific requirements.
