The commercial, operational and environmental advantages of Cargotec’s continuous screw unloading technology have led to several recent orders, all for unloading coal cargoes, including one for a state-owned port in northeast Brazil
In December Cargotec received an order for a Siwertell ST 940-D ship unloader from the Ministry of Infrastructure (SEINFRA) in Ceará State, Brazil. Constructed in Sweden and China, the continuous screw unloader will be installed at the port of Pecem, Ceará State, in the northeast of the country and will be ready for use by the end of 2011. A decision on an order for a second, similar unloader for the same jetty is expected to be taken by 2011.
With an unloading capacity of 2,400 tonnes per hour the Siwertell equipment will discharge coal from partly loaded Capesize vessels of up to 100,000 dwt.
Douglas Wichers, Cargotec’s sales manager for bulk terminals, says there are a number of good reasons why SEINFRA in Ceará State chose the company’s continuous screw unloader. “In the first place, it is the most environmentally friendly unloading system on the market as there are no dust emissions or spillages.
“It has the highest average unloading capacity when compared with competitor systems, yet the unit weight of the Siwertell unloader is only about half that of a grab crane, so there is no need to reinforce the jetty prior to installation.
“The small physical size of the Siwertell unloader eliminates the risk of collision with the large clamshell grab cranes that are to be installed at the same jetty.
“From a commercial point of view, the high average unloading capacity will result in low demurrage costs for the bulk carriers using the jetty.”
Cargotec has unrivalled experience in continuous screw type unloading systems, and has recently secured other significant orders for delivery in 2011 and 2012. These include another order to Brazil; one to Taiwan; and one to Korea.
