Mumbai (Maharashtra) [India], April 09:<\/strong> Knowledge Marine & Engineering Works Limited (KMEW) is pleased to announce the commissioning of River Pearl 47, the largest and deepest Indian-flag, self-propelled backhoe dredger, at Jawaharlal Nehru Port Authority (JNPA) under contract with the Dredging Corporation of India. This significant addition further strengthens KMEW\u2019s specialized dredging fleet and reinforces its capability to execute complex marine infrastructure and port development projects across India.<\/p>\n

River Pearl 47 is equipped with a Japanese-built Komatsu PC 2000 heavy-duty excavator mounted on a hydraulically operated three-legged spud barge powered by dual engines. The Komatsu PC2000 is a 200-tonne class hydraulic excavator designed for demanding \u00a0 dredging, mining, and large-scale infrastructure operations. The excavator was procured from abroad and has been integrated with the spud barge at Mumbai Port by the KMEW Group engineers, keeping in mind the stability and the structural integrity of the barge.<\/p>\n

\u00b7 \u00a0 \u00a0 \u00a0 ~1000 BHP engine delivering superior hydraulic performance<\/p>\n

\u00b7 \u00a0 \u00a0 \u00a0 Multiple boom and arm configurations enabling dredging depths from 4 meters to 30 meters below water level<\/p>\n

\u00b7 \u00a0 \u00a0 \u00a0 Bucket capacity ranging from 1.75 m\u00b3 to 12 m\u00b3 depending on configuration<\/p>\n

\u00b7 \u00a0 \u00a0 \u00a0 High cycle efficiency for faster and more precise dredging operations<\/p>\n

Barge\u00a0Specifications<\/strong><\/p>\n

\u00b7 \u00a0 \u00a0 \u00a0 Length: 50 meters<\/p>\n

\u00b7 \u00a0 \u00a0 \u00a0 Width: 14 meters<\/p>\n

\u00b7 \u00a0 \u00a0 \u00a0 Spud Length: 32 meters<\/p>\n

\u00b7 \u00a0 \u00a0 \u00a0 Draft: Less than 4 meters, enabling shallow water operations<\/p>\n

\u00b7 \u00a0 \u00a0 \u00a0 Accommodation: 20 personnel<\/p>\n

\u00b7 \u00a0 \u00a0 \u00a0 Clear Deck Area: 300 square meters<\/p>\n

\u00b7 \u00a0 \u00a0 \u00a0 4-point mooring winch system<\/p>\n

\u00b7 \u00a0 \u00a0 \u00a0 Multiple positioning systems achieving sub-meter accuracy in open sea conditions<\/p>\n

Operational\u00a0Capabilities<\/strong>
The backhoe dredger is designed for accurate excavation of stiff seabed layers including\u00a0clay,\u00a0rock,\u00a0and\u00a0boulders\u00a0in\u00a0shallow\u00a0to\u00a0deep\u00a0waters.\u00a0River\u00a0Pearl\u00a047 is ideally suited for dredging high spots in ports, creating precise pipeline trenches, and removing blasted rock-operations where conventional dredgers often face limitations.<\/p>\n

Key\u00a0Applications<\/strong><\/p>\n

\u00b7 \u00a0 \u00a0 \u00a0 Port and Harbour Development: Deepening and widening channels and berths with high precision<\/p>\n

\u00b7 \u00a0 \u00a0 \u00a0 Hard Material Removal: Dredging hard clay, cemented gravel, and fractured rock<\/p>\n

\u00b7 \u00a0 \u00a0 \u00a0 Trenching and Pipeline Work: Accurate excavation for subsea cables and pipelines<\/p>\n

\u00b7 \u00a0 \u00a0 \u00a0 Environmental Dredging: Targeted sediment removal with minimal over-dredging<\/p>\n

\u00b7 \u00a0 \u00a0 \u00a0 Confined Area Operations: Effective manoeuvrability in narrow harbours and canals<\/p>\n

Key\u00a0Features<\/strong><\/p>\n

\u00b7 \u00a0 \u00a0 \u00a0 High precision horizontal and vertical control<\/p>\n

\u00b7 \u00a0 \u00a0 \u00a0 Limited turbidity and reduced environmental impact<\/p>\n

\u00b7 \u00a0 \u00a0 \u00a0 Spud-mounted robust stability for high digging force<\/p>\n

\u00b7 \u00a0 \u00a0 \u00a0 Versatile operations in shallow waters and depths up to 30 meters<\/p>\n

The commissioning of River Pearl 47 has enhanced KMEW\u2019s capability to undertake\u00a0technically\u00a0challenging\u00a0dredging\u00a0assignments\u00a0and\u00a0supporting India\u2019s\u00a0growing\u00a0port\u00a0and\u00a0maritime\u00a0infrastructure\u00a0development.<\/p>\n

The\u00a0project involves chartering specialized dredging equipment to carry out pre-treatment and rock dredging at the coastal berth area of Jawaharlal Nehru Port, Mumbai. The work includes drilling, controlled blasting, and removal of approximately 10,500 cubic meters of hard rock to achieve design depths of 11\u201312 meters below chart datum. All dredged material will be transported and disposed of at a designated offshore dumping site, with the contractor responsible for surveys, mobilization, permissions, and execution on a turnkey basis.<\/p>\n

The scope extends beyond dredging to include associated activities such as environmental monitoring, obtaining regulatory approvals, and ensuring safe handling of explosives. The contractor bears full responsibility for any damage to port infrastructure during operations and must secure appropriate risk insurance. Given the operational nature of the berth, the contractor must ensure that port activities remain uninterrupted and deploy suitable equipment and methodologies accordingly.<\/p>\n
