Thordon’s salt lugger solution

Thordon’s salt lugger solution

(Posted on 03/12/18)

Thordon Bearings has completed a range of water-lubricated and grease-free bearing installations to a third salt lugger in the Salinor/Navenor fleet, following the successful retrofitting of bearings to problematic newbuilds.

The Brazilian owner opted for the Thordon package following the rapid failure of the bronze and phenolic bearings supplied by a competitor to two newbuilds at the Manaus Shipyard delivered in 2015.

The salt carrier Nossa Sra. das Das Vitorias was retrofitted with Thordon’s SXL propeller shaft bearings after just three weeks of operation, while sistership Dona Zita was retrofitted with RiverTough shaft bearings and hardened steel liners in 2016.

José Fabio S. Camocardi, Managing Director, Thortech, Thordon Bearing’s São Paulo-based distributor, takes up the story.

“Salinor/Navenor’s dedicated carriers transport salt from mines located around the Northeast of Brazil area to discharge points offshore Brazil for loading on to larger ocean-going bulk carriers.

“Because these vessels operate in both inland rivers and coastal seas, the blue water bearings and liners originally supplied were not suitable for operation in dirtier waters, especially those with a high sand and silt content. They failed. We were contacted to find a solution, first for the Nossa Sra. das Das Vitorias and, later, Dona Zita. The bearing retrofits have now provided trouble-free operation in all types of water in which these vessels operate.”

Based on the success of the Thordon installations, Navenor approached Thortech to supply a complete shaft and rudder bearing and seal package for the newbuild shallow draught bulker Comandante Paschoal.

Rio de Janeiro’s São Miguel shipyard delivered the vessel in August 2018. The scope of supply comprised a pair of RiverTough propeller shaft bearings, NCB liners and three TG100 mechanical seals for shaft diameters of 135mm, Thordon SXL rudder bearings for rudder shaft diameters of 168mm, and grease-free ThorPlas-Blue bearings for the vessel’s tiller arms and rudder stocks.

Scott Groves, Thordon’s Regional Manager – Americas, said: “The customer had so many problems with the bearings supplied to the Nossa Sra. das Das Vitorias and Dona Zita that a completely new approach was required for the São Miguel newbuilds. Following the earlier retrofit installations we were able to win the customer’s confidence. In addition to the Comandante Paschoal installation, we have also been contracted to provide the full shaft line specification for a new salt carrier due for delivery next month. Thortech is also negotiating the supply of Thordon bearing solutions for a newbuild planned for 2019.”

Salinor Salinas do Nordeste S.A. is Brazil’s premier salt manufacturer, providing more than 40% of sea salt production in Brazil. Navenor, a Salinor company, is responsible for the transportation of Salinor’s sea salt.
