FAQ: 3,500 m³/h CCS Classed Cutter suction dredger (High-Power Triple Pump Series)

Q1: How does the "Triple Pump Series" configuration enable a 10 km discharge distance, and what are the specific pump specifications?

A: This vessel utilizes a high-efficiency triple-pump series system designed for long-distance reclamation without the immediate need for floating Booster Stations.

System Configuration: The system combines one Underwater Pump and two Onboard Pumps working in series to boost pressure progressively.

Underwater Pump: Capacity of 12,500 m³/h (clear water) with a head of 32m, powered by a 2,200 kW drive (CSR 12V280 engine).

Onboard Pumps: Two units, each with a capacity of 12,500 m³/h (clear water) and a high head of 65m. Each is driven by a 3,600 kW MAN 32/40 engine (Total onboard pump power: 7,200 kW).

Operational Advantage: The combined head pressure allows the slurry to be pumped reliably up to 10 km through an 800 mm diameter pipeline. This significantly reduces operational costs and logistical complexity for medium-to-long distance land reclamation projects compared to standard single or dual-pump dredgers.

Q2: With a total installed power of 13,500 kW, how does this vessel perform in hard soil excavation and what is its maximum working depth?

A: The massive 13,500 kW total installed power positions this dredger as a heavy-duty excavator capable of handling tough substrates.

Cutter Performance: The Cutter Head is driven by a robust 1,650 kW system, powered by a CSR 12V280 (2,600 kW) diesel engine. This high torque output ensures efficient cutting of dense clay, gravel, and weathered rock without stalling.

Maximum Depth: The vessel is engineered to operate at a maximum excavation depth of 28 meters, making it suitable for deepening deep-water ports and channels where larger draft vessels are required.

Power Redundancy: The high total power includes dedicated generation for pumps, cutters, and auxiliary systems (including 880 kW main generators), ensuring that full production capacity is maintained even under peak load conditions.

Q3: What are the vessel's structural dimensions and maneuverability features that support its offshore operational stability?

A: Designed for stability in offshore environments, the vessel combines a large hull form with precise positioning capabilities.

Structural Dimensions: It features a substantial hull with a Length of 108m, Beam of 18.6m, and a Depth of 5.7m. With a full load draft of 3.95m, it offers a stable platform that minimizes rolling during heavy cutting operations.

Maneuverability & Reach: The dredger has a maximum swinging radius of 100m, allowing it to cover a wide arc without frequent repositioning of the spuds. This wide swing capability, combined with the powerful winch systems (implied by the high horsepower), ensures high production efficiency in both confined port areas and open coastal reclamation sites.

Offshore Readiness: The depth and beam ratio provides excellent hydrostatic stability, essential for maintaining the precise cutter position required when operating at the maximum 28m depth in varying sea states.
