Demag Cranes supplies further Floating Cranes for the Mississippi River

Düsseldorf,   28. July 2011

  • Customer St. James Stevedoring Partners, Llc, orders cranes 7 and 8
  • Largest Floating Cranes on the Lower Mississippi River
  • Verifiable weighing system for maximum transparency

Gottwald Port Technology GmbH (Gottwald), a subsidiary of Demag Cranes AG, has been awarded a contract to supply two more Floating Cranes to St. James Stevedoring Partners, Llc, Louisiana, USA, which will already enter service on the Mississippi River in the autumn of this year. The customer already operates six Gottwald Floating Cranes. Instead of the conventional rubber-tyred chassis that Mobile Harbour Cranes are usually installed on, the Floating Cranes are mounted on barges.

“With our two new Gottwald Floating Cranes, we aim to achieve a flexible increase in our cargo handling capacities and usefully extend our existing logistics”, states Paul E. Morton, President of St. James Stevedoring Partners, Llc. “Our customers expect rapid handling of their cargo despite increasing volumes. This goal can only be achieved with high-end cranes, handling rates and reliability.”

Thomas H. Hagen, Member of the Management Board of Demag Cranes AG and COO, states, “Thanks to their high performance and versatility, our Floating Cranes are becoming more and more established in the market, as shown again by the follow-up order received from St. James.”

Gottwald cranes provide significant increase in handling capacity
St. James Stevedoring Partners, Llc, in Convent, Louisiana, with six mid-stream buoys served by Gottwald Floating Cranes ranging from mile marker (MM) 122 (located just outside of New Orleans International Airport) up to MM 167 on the Lower Mississippi River, aims to extend its handling capacity in mid-stream operation. The two Model 8 variant G HPK 8400 B Floating Cranes will be added to the existing fleet and are intended to make the transhipment of bulk goods including ores, coal, cereals and fertilisers from larger vessels, up to Baby-Capesize, to barges even more efficient.

The Demag Cranes Group subsidiary, Gottwald Port Technology, already supplied the first Floating Crane, an HPK 330 EG, to St. James Stevedoring Partners, Llc, in 2004, where it has since been in service for more than 42,000 hours of operation. It was the first crane of its kind to be developed in close co-operation together with the customer by Gottwald Port Technology, the leading supplier of Mobile Harbour Cranes. “To meet growing requirements, we naturally selected the world market leader once again, since they understand and cater to our needs in full,” continues St. James Stevedoring President Morton.

Highest-performance Gottwald Floating Cranes
The two G HPK 8400 B built for St. James Stevedoring Partners, Llc, are the first Gottwald Floating Cranes that can handle heavy loads weighing up to 100 tonnes. For handling bulk goods, they have the highest-performance 63-tonne grab curve that Demag Cranes has installed on a Floating Crane until now. In crane classification A8, this enables them to have a radius of up to 37 metres, and even up to 39 metres in A7. Depending on operating conditions, the G HPK 8400 B cranes can each handle up to 1,850 tonnes of bulk material per hour. This makes them the largest and highest-performing Floating Cranes of their kind on the Lower Mississippi River.

New technology: verifiable weighing system provides for improved transparency
Featuring a new technology, they are also fitted with a verifiable weighing system that is installed direct on the crane. This system is far more precise than conventional load measuring solutions on cranes and can be integrated into the handling process more easily than external weighing systems. “Thanks to this innovation, in future we will be able to offer our customers complete transparency with reference to the transhipped goods”, explains Morton. The new system has already been approved for use as a verifiable solution in the European Union. Regardless of the immediately useful transparency benefit provided by the system, St. James Stevedoring Partners, Llc, is also submitting it for corresponding certification with the US testing authority. There are also plans for an officially approved crane weighing system that is specially designed for cereals to replace today’s weighing solutions with chutes mounted on barges.

Environmentally friendly operation
Floating Cranes such as the Model 8 variant G HPK 8400 B supplied by Gottwald also meet the increasing Green Port efforts being pursued by port and terminal operators. The diesel-electric drive concept typically employed by Gottwald offers good efficiency, which pays off in terms of low fuel consumption and minimised exhaust emissions. New types of dynamic brake resistors also provide for optimised energy management in the cranes, resulting in savings of up to 15.2 per cent (achieved under specific deployment conditions and based on experience gained from operating a Gottwald Generation 5 crane over a period of more than one year).
