Navgathi Marine: Two Cutter Suction Dredgers Delivered (India)

October 11, 2012

It was a momentous occasion for Navgathi Marine Design & Constructions Pvt Ltd, with the successful delivery of two cutter suction dredgers for Irrigation Department, Kerala State.

The dredgers were contracted to KSINC for construction and the work was done by APM Marine.

Navgathi Marine Design did the complete design of the dredger from basic design to production design and also provided technical support during construction. The compact dredger is designed to operate in shallow and narrow waters. All the controls are centrally located for ease of use.

The entire system is run on a centrally located hydraulic system with a pump driven by the engine. The vessel is designed as per the requirements of IRS Classification Society.

Marine grade steel, surface preparation, coating and equipments are used for longer life under the harsh operating condition

Navgathi developed the design after an extensive market survey on the type of vessels in the Kerala waters and the operational issues associated with them.
