 DEPTH : 7.70 m5

Piling System Parameters (Detailed)

1. Core Piling Frame Specifications

• Piling frame height: 90m (above deck)

• Frame structure: External leader type, stable triangular support

• Leader section size: 1.0m × 1.0m (high-strength steel material)

• Tilt adjustment range: 0°–15° (supports inclined piling for special foundations)

• Frame weight: 380t (ensures stability during heavy piling)

• Leader to bow distance: 5.5m (optimizes operation space for pile hoisting)

2. Piling Capacity & Performance

• Maximum pile weight: 180t (suitable for large-diameter heavy piles)

• Maximum pile diameter: 3.5m (adapts to monopiles, jacket piles, and concrete piles)

• Maximum pile length: 85m (covers most coastal/offshore foundation depth needs)

• Pile lifting point height: 88m (above deck, meets long pile hoisting requirements)

• Hammer center height: 95m (above deck, ensures sufficient hammer stroke)

• Pile positioning accuracy: ±50mm (high-precision control for foundation quality)

3. Piling Hammer & Power System

• Hammer type: Hydraulic impact hammer (model: HHP40)

• Maximum impact energy: 600kJ (suitable for hard soil/rock layers)

• Hammer stroke range: 0.5m–2.0m (adjustable for different pile types)

• Hammer weight: 45t (matches pile weight for efficient driving)

• Hydraulic system pressure: 28MPa (stable power output for continuous operation)

• Hammer control mode: Electric-hydraulic proportional control (precise impact force adjustment)

4. Auxiliary Piling Machinery

• Main piling winches: 2 sets, single-line pull 350kN, rope speed 0–12m/min (for pile lifting)

• Hammer lifting winches: 1 set, single-line pull 200kN, rope speed 0–8m/min (for hammer positioning)

• Pile clamping device: Hydraulic self-locking type, clamping force 800kN (prevents pile slipping)

• Frame adjustment winches: 4 sets, single-line pull 150kN each (for frame tilt and alignment)

• Guide roller system: High-wear-resistant steel rollers (reduces pile friction during driving)

5. Piling Control & Monitoring

• Control system: PLC intelligent control (integrates winch, hammer, and frame adjustment)

• Monitoring parameters: Pile penetration depth, hammer impact frequency, pile verticality (real-time display)

• Safety protection: Overload protection, emergency stop, and verticality deviation alarm (ensures operation safety)

Applications:

Offshore Wind farm foundation piling (monopile, jacket pile)

Coastal port, wharf and terminal piling construction

Cross-river/sea bridge pier pile foundation engineering

Marine revetment and coastal protection piling works

Offshore platform and small-scale offshore structure piling

Advantages:

Strong piling performance: Max pile diameter 3.5m, max pile length 85m, adapting to most coastal engineering needs

Stable operation: Wide hull design and reliable anchoring system ensure safety under complex coastal conditions

High efficiency: Equipped with professional hydraulic piling hammer and precise positioning winches, reducing construction cycle

Flexible adaptation: Suitable for multiple pile types (Steel Pipe pile, concrete pile) and various soil conditions

Good equipment condition: Well-maintained core components (piling frame, winches) with stable working performance

Cost-effective: Optimized power system and low maintenance requirements, controlling operation costs



FAQ:

Q: How long after payment will the vessel be delivered?

A: Generally, the vessel can be delivered within one to two months after signing the MOA and paying the deposit according to its terms.

Q: Can you provide crew training for the buyer's construction personnel?

A: Training for the buyer's construction personnel and crew is divided into two categories:

1. Short-term Familiarization: This is generally for the buyer's senior crew members or operators. They can be dispatched to China before delivery to learn operations and familiarize themselves with the equipment on board. (Free of Charge)

2. Long-term Training: This requires dispatching Chinese crew members and operators to the vessel's location in the buyer's country. They will be responsible for vessel operations and training the crew during actual operations. (Requires a separate contract and is chargeable)
