HollandMT designs spud system for Backhoe

In cooperation with FKAB, HollandMT has supplied a design for a spud lifting system for a backhoe dredger. The spud lifting system is powered by hydraulic winches which also allow free floating of the moored dredger. To absorb shock loads during dredging operations, the spud trunks will be fitted with special rubber buffer elements.

The backhoe dredger will be self propelled, fitted with 3 spud lifting systems and carry a Liebherr 984C excavator or equivalent.

Expected delivery time of the backhoe is 3rd quarter 2016 and the main operating area for the backhoe will be North Africa.

Official handover of TSHD KAO505

On June 12th, the 2400 m3 TSHD named KAO505 was officially handed over to TIPC, harbor authority of Kaohsiung port, Taiwan. The KAO505 was designed bij FKAB in cooperation with HollandMT and constructed at Ching Fu Shipyard. HollandMT supplied the complete dredging system and congratulates TIPC and Ching FU with the excelent performance dredger. 

4500 kW submerged pump unit succesfully commissioned

Through our technology partner GIW industries, the following press release was issued:

GIW Industries, Inc., a company involved in the design, manufacture and application of heavy duty centrifugal slurry pumps, has announced the successful design and installation of a unique underwater pump system for a Chinese dredging contractor.

This equipment package consists of a GIW® Minerals LHD pump directly mounted onto a 4500 kW submersible electric motor and housed in a carrier arm attached to the drag arm of a trailing suction hopper dredger.

The upgrade allows the dredger to operate efficiently at depths up to 100 meters.

The 58″ impeller and 4500 kW/6000 hp motor significantly decrease the filling time of the 15,000 cubic meter hopper when operating at depths in excess of 35 meters, thereby increasing the overall efficiency of the dredger.

For this project HollandMT has provided basic and detailed design of the complete underwater pump unit, including frame, structural analyses, piping, auxiliary systems and routing of e-cables.

For this project HollandMT also provided supervisory assembly services at the shipyard in China.
