FAQs:  

Q1：What is the vessel type and core application of this vessel?

A：It is an 8000m³ self-propelled trailing suction hopper dredger with twin propellers, twin nozzles, twin-engine compound drive and twin drag heads. It is suitable for dredging and reclamation projects in coastal ports and waterways, as well as coastal maintenance works.

Q2：What are the restrictions on the navigation and construction scope of the vessel's service area?

A：The navigation scope is unrestricted service area, and the construction area is limited to coastal waters.

Q3：What core certificates will be provided upon delivery

A：Four sets of certificates (1 original + 3 copies) will be provided, including classification certificate, International Load Line Certificate, Cargo Ship Construction/Equipment Safety Certificate, International Oil Pollution Prevention Certificate (IOPP), International Ship Security Certificate (ISSC), Air Pollution Prevention Certificate (Tier III), Radio Safety Certificate (GMDSS) and other key certificates.

Q4：What are the core principal dimensions and deadweight data of the vessel?

A：Overall length: approx. 122.5m, length between perpendiculars: 115.0m, molded breadth: 24.6m, molded depth: 8.9m; average molded draft at summer load line: 6.0m, dredging draft: 7.5m; maximum hopper capacity: 8000m³, dredged material capacity: approx. 11600t, total deadweight: approx. 12550t (at 7.5m draft).

Q5：Which soil types can the vessel dredge, and what is the maximum dredging depth?

A：It can dredge silt, clay, fine silty sand, medium-fine sand, coarse sand, crushed stone and pebbles; maximum dredging depth: 60m (when starboard extended drag pipe forms 59° angle with baseline), conventional dredging depth: 40m (when drag pipe forms 35°/48° angle with ship baseline).

Q6：What is the hopper Loading and shore discharge efficiency of the vessel?

A：Hopper loading efficiency: For medium-fine sand, at 40m dredging depth, twin underwater pumps take approx. 46 minutes; twin inboard pumps take approx. 95 minutes; at 60m dredging depth, single underwater pump takes approx. 92 minutes. Shore discharge efficiency: Twin inboard pumps in series take approx. 75 minutes for shore discharge via 3500m pipeline, with maximum shore discharge distance of 5500m.

Q7：What are the vessel's speed, range and endurance?

A：Full-load speed (at 7.5m dredging draft): approx. 13.6 knots; speed through water during dredging: not less than 6.5 knots (approx. 2.5 knots over ground with 4.0 knots countercurrent). Both range and endurance are approx. 20 days (at 85% MCR, based on fuel oil, fresh water tank capacity and deadweight).

Q8：What is the core configuration of the vessel's power and dredging systems?

A：Power system: 2 propulsion diesel engines (4500kW/750rpm each), 2 shaft-driven generators (4300kW each), 1 auxiliary diesel generator set (approx. 800kW), 1 emergency generator set (approx. 250kW). Dredging system: 2 underwater pumps (1350kW each), 2 inboard pumps (2800kW each), 2 electrically-driven high-pressure flushing pumps (800kW each), twin drag heads (with high-pressure flushing and detachable teeth).

Q9：What are the highlights of the vessel's control and automation configuration?

A：The wheelhouse can remotely control the propulsion system and dredging system (drag pipes, dredge pumps, mud doors, etc.); equipped with 2 350kW variable frequency motor-driven fixed-pitch bow thrusters to improve maneuverability; provided with dredging control system and navigation console, integrated with DGPS, radar, ECDIS and other navigation equipment to meet the needs of automated operations.

Q10：What is the configuration of fuel oil and fresh water tank capacity?

A：Total heavy fuel oil tank capacity: approx. 905m³ (deadweight 525t), total light diesel oil tank capacity: approx. 100m³ (deadweight 30t), total lubricating oil tank capacity: approx. 40m³ (deadweight 20t), total fresh water tank capacity: approx. 300m³ (deadweight 120t).

Q11：What does the vessel's life-saving and deck machinery configuration include?

A：Life-saving equipment: 1 fully enclosed lifeboat with 30-person capacity; deck machinery: 1 18-ton hydraulic fixed crane at the bow (30m span), 1 15-ton hydraulic fixed crane at the stern (30m span), used for equipment maintenance and heavy lifting.
