Jack Up Wind Farm Installation Platform

Shandong Haiding Shipbuilding Co., Ltd.  is a famous Jack up wind farm installation platform manufacturer and supplier in China. If you want to buy high-quality and the newest products, please contact us immediately. HAIDING SHIPYARD Jack up working platform is a heavy-duty wind power construction equipment designed for 3-100m marine water depth, with spud leg design length of 50-150m and total platform load capacity of 3000 tons. It core-integrates an 800-ton class 360° slewing crane, wind power foundation leveling system, and tower barrel/main engine docking module, focusing on three core tasks: offshore wind power pile driving, tower barrel splicing, and installation of 16MW and above wind turbine main engines. Aiming at the pain points of wind power installation such as "large-tonnage hoisting demand, high-precision docking requirements, and strong interference from complex sea conditions", it realizes stable wind power installation operations from shallow sea to deep sea through CCSB steel plate rigid structure (yield strength ≥235MPa), full-automatic platform leveling (±0.05°), and strong wind-wave resistance design (Grade 12 wind resistance). The installation cycle of a single wind turbine is ≤72 hours, 40% more efficient than traditional floating cranes, providing a "high-load, high-precision, high-efficiency" installation solution for large-scale offshore wind power development.

Core Advantages

Large-Tonnage Hoisting Capacity, Adapted to Large-Scale Wind Power Installation

800-Ton Class Crane Integration: HAIDING SHIPYARD Jack up wind farm installation platform equipped with a full-hydraulic 360° slewing crane (maximum rated lifting capacity 800 tons, maximum working radius 45 meters), main hook lifting height ≥120 meters, auxiliary hook lifting height ≥150 meters, capable of lifting 16MW wind turbine main engines (weight ≤600 tons) and 70-meter class tower barrels (single-section weight ≤300 tons); the crane adopts dual winch synchronous control (synchronization accuracy ±0.1m), ensuring coaxiality deviation ≤1mm during tower barrel splicing;

Wind Power-Specific Hoisting Aids: HAIDING SHIPYARD Jack up wind farm installation platform equipped with wind turbine-specific spreaders (adapting to different specifications of main engines/tower barrels) and hydraulic jacking devices (adjustment accuracy ±0.05m), enabling precise docking of main engines and tower barrels; the platform reserves wind power foundation leveling interfaces, and cooperates with laser levelers (accuracy ±0.02°) to ensure the horizontal error of the pile foundation top ≤0.1°, laying the foundation for subsequent installation.

High-Precision Control, Reliable Installation Quality

Full-Automatic Leveling & Positioning: Adopting a three-axis inclination sensor (accuracy ±0.02°) and GPS+Beidou dual positioning system (positioning accuracy ≤0.5m), the platform automatically levels before hoisting (level error ≤0.05°), and real-time compensates for platform tilt caused by wind and waves during hoisting (compensation speed ≤0.1m/min), ensuring the main engine hoisting positioning deviation ≤0.5m and avoiding collision with the tower barrel;

Dynamic Load Monitoring: The HAIDING SHIPYARD Jack up wind farm installation platform is equipped with a high-precision load sensor (accuracy ±1%) and torque limiter, real-time monitoring the hoisting weight and torque, automatically alarming when approaching 90% of the rated value, and forcibly stopping when exceeding the rated value; the platform deck is equipped with stress monitoring points (CCSB steel plate stress ≤200MPa) to avoid structural damage caused by overloading.

Modular Deployment, Convenient Operation & Maintenance

Sectional Transportation & Assembly: The HAIDING SHIPYARD Jack up wind farm installation platform is split into 7-9 sections (main platform section, spud leg section, crane module section, all welded with CCSB steel plate) with maximum single-section weight ≤150 tons, which can be transported globally by semi-submersible ships and ocean-going barges; on-site assembly is completed with flanges + prestressed bolts, and takes 12-18 days with marine floating cranes, 30% shorter than the deployment cycle of traditional wind power installation ships;

Modular Maintenance of Equipment: The crane winch and luffing mechanism adopt modular design, which can be disassembled and replaced as a whole in case of failure, reducing maintenance time to 15 hours/time; the spud leg rack is quenched and tempered with CCSB steel plate (hardness ≥200HB), with service life ≥25 years in deep-sea environment, and annual maintenance cost 25% lower than traditional installation ships.

Detailed Technical Parameters

Core Application Scenarios

Foundation Leveling & Grouting: After pile driving, adjust the foundation level (error ≤0.1°) through the platform leveling system, and cooperate with grouting equipment to complete grouting between the pile foundation and the transition section; the CCSB deck steel plate has stable load-bearing capacity, capable of carrying 200-ton grouting equipment for long-term operations, ensuring the foundation strength meets design requirements.

Tower Barrel & Main Engine Installation

16MW Main Engine Installation: In wind farms with 80-100m water depth in the South China Sea, hoist 16MW wind turbine main engines with weight 550-600 tons; the crane's main hook lifting height ≥120 meters, and cooperate with hydraulic jacking devices to adjust the main engine attitude (adjustment accuracy ±0.05m) to realize precise docking of the main engine and tower barrel; the installation cycle of a single main engine is ≤36 hours, 40% more efficient than traditional floating cranes.

Wind Power Operation & Maintenance Support

Operation & Maintenance Material Transfer: Serve as a temporary offshore wind power operation and maintenance base, storing maintenance consumables (such as lubricating oil, tools) and daily supplies, and transferring them to each wind turbine platform via the crane, reducing the number of maintenance ship trips and improving maintenance efficiency, especially adapting to the long-term maintenance needs of remote deep-sea wind farms.

Customization Services

Parameter & Function Customization: Adjust spud leg length (up to 150m) and crane configuration according to wind farm water depth (e.g., upgrading to 1000-ton class crane to adapt to 20MW wind turbines); for polar sea areas, thicken CCSB steel plate to 70mm and add insulation layer, upgrade the low-temperature adaptability of the crane hydraulic system (startable at -30℃); for high-temperature and high-humidity sea areas, optimize the platform anti-corrosion coating (add graphene anti-corrosion layer);

Value-Added Services: Assist in providing CCSB steel plate material certification (complying with CCS marine steel specifications), platform classification certification (ABS/CCS/DNV) and wind power installation operation permits; provide wind power installation technical support (hoisting plan design, equipment docking simulation); connect with wind power development enterprises to provide "platform + installation + operation and maintenance" integrated services, ensuring efficient advancement of wind power projects.
