Jack Up Working Platform

As the professional manufacturer, we would like to provide you high quality Jack up working platform.

HAIDING SHIPYARD Jack up Working Platform is a universal operation equipment designed for 3-100m marine water depth, with spud leg design length of 10-100m and total platform load capacity of 3000 tons. Focusing on "modular functional cabins + flexible adaptation", it covers four scenarios: general marine engineering construction, temporary equipment storage, marine emergency operations, and scientific research monitoring support. Aiming at the pain points of traditional dedicated platforms such as "single function, poor scenario adaptability, and long deployment cycle", it realizes "one platform for multiple uses" through interchangeable operation modules (hoisting/storage/construction), high-precision leveling (±0.1°), and wind-wave resistance design (Grade 11 wind resistance). The operation switching time is ≤48 hours, providing a "flexible, efficient, low-cost" universal operation solution for marine engineering.

Core Advantages

Modular Functional Design, Multi-scenario Adaptation

Interchangeable Operation Modules: The HAIDING SHIPYARD Jack up Working Platform reserves standardized interfaces, supporting rapid switching of 3 core modules - hoisting module (50-200 ton crane), storage module (300-800m³ sealed cargo hold), construction module (concrete mixing plant/welding workstation). Modules are fixed by hydraulic locks, with switching time ≤48 hours, adapting to the full-process needs from material transfer to on-site construction;

Extended Functional Cabin Installation: Additional living cabins (accommodating 20-50 people), power generation cabins (500-1000kW diesel generators), and scientific research cabins (equipped with water quality/meteorological monitoring equipment) can be installed, forming an integrated "operation + support + research" platform without additional supporting ships.

High-precision Stability Control, High Operation Safety

Full-automatic Leveling & Positioning: HAIDING SHIPYARD Jack up Working Platform equipped with dual-axis inclination sensor (accuracy ±0.05°) and GPS+Beidou dual positioning (accuracy ≤1m), the platform automatically levels after lifting (level error ≤0.1°), and real-time compensates for wind-wave tilt during operation, ensuring the stability of high-precision operations such as hoisting and welding (hoisting positioning deviation ≤0.5m, welding verticality deviation ≤1mm);

Rigid Operation Surface Design: The operation area of the HAIDING SHIPYARD Jack up Working Platform adopts reinforced deck (CCSB wear-resistant modified steel plate, thickness ≥30mm), equipped with retractable support legs (single leg support force ≥300kN), forming an independent rigid operation surface, avoiding the impact of equipment vibration on operation accuracy, and adapting to long-term operation of heavy equipment (CCSB steel plate yield strength ≥235MPa, complying with marine structural steel specifications).

Full Water Depth Coverage, Complex Environment Tolerance

Flexible Spud Leg Customization: HAIDING SHIPYARD Jack up Working Platform adopts 3-4 sectional truss spud legs (diameter 2.5-3.0m, material: CCSB steel plate) with customizable length of 10-100m - 10-30m short legs for shallow sea (3-20m), 30-60m medium legs for medium sea (20-50m), 60-100m long legs for deep sea (50-100m); spud cans adopt expandable design (contact area ≥60㎡, material: CCSB steel plate) to prevent sinking into soft soil or sandy seabed;

Harsh Environment Protection: The HAIDING SHIPYARD Jack up Working Platform has Grade 11 wind resistance, wave resistance height ≤5m, current resistance speed ≤2 knots. All modules are equipped with IP65 dustproof and waterproof sealing, and living cabins/scientific research cabins are equipped with constant temperature systems (20-26℃), enabling continuous operation during the South China Sea monsoon period and Bohai Bay winter low-temperature period (CCSB steel plate has excellent low-temperature toughness, impact energy ≥27J at -20℃).

Convenient Deployment & Maintenance, Controllable Cost

Sectional Transportation & Assembly: The HAIDING SHIPYARD Jack up Working Platform is split into 5-7 sections (main platform section, spud leg section, module section, all welded with CCSB steel plate) with maximum single-section weight ≤100 tons, which can be transported globally by ocean-going barges/semi-submersible ships; on-site assembly is completed with flanges + prestressed bolts, and takes 8-12 days with floating cranes, 40% shorter than the deployment cycle of traditional integral platforms;

Modular Maintenance: Core components (spud leg rack, hydraulic system, module interface) adopt modular design, which can be replaced as a whole in case of failure, with maintenance time ≤10 hours/time; the spud leg rack is quenched and tempered with CCSB steel plate (hardness ≥200HB), with service life ≥20 years in deep-sea environment, and annual maintenance cost 30% lower than dedicated platforms.

Detailed Technical Parameters

Core Application Scenarios

General Marine Engineering Construction

Wind Power Foundation Preprocessing: In wind power projects along the coasts of Jiangsu and Fujian, equipped with construction modules (concrete mixing plant + steel processing equipment), complete concrete pouring and protection around wind power pile foundations. The stable operation surface of the platform (CCSB deck steel plate wear coefficient ≥0.6) ensures the pouring flatness error ≤0.3m;

Cross-Sea Pipeline Auxiliary Construction: In the underwater pipeline laying project in the Qiongzhou Strait, equipped with hoisting module (100-ton crane) and storage module (500m³ cargo hold), transfer pipeline sections and assist in docking, with positioning accuracy ≤0.5m, shortening the pipeline laying cycle (CCSB spud leg steel plate seawater corrosion rate ≤0.1mm/year).

Temporary Storage & Transfer

Offshore Material Reserve: In the development of oil and gas fields in the South China Sea, serve as a temporary material transfer station, equipped with storage module (800m³ sealed cargo hold) to store drilling consumables and daily supplies, and transfer to production platforms with hoisting modules, reducing the number of transport ship trips (CCSB cargo hold steel plate welded joint strength coefficient ≥0.9);

Temporary Equipment Storage: In the renovation project of old platforms, equipped with storage modules to store equipment to be replaced (such as pump units, valves). The stable mooring of the platform can prevent equipment damage from moisture, and cooperate with construction modules to complete equipment preprocessing (CCSB platform structure steel plate low-temperature toughness meets -20℃ operation requirements).

Marine Emergency Operations

Oil Pollution Emergency Treatment: In the oil tanker leakage accident in the Bohai Bay, quickly deploy the platform (assembly ≤12 days), equipped with oil pollution recovery modules (oil skimmers + oil storage tanks) and living cabins, recover oil pollution on the sea surface and provide accommodation for emergency teams, with Grade 11 wind resistance to operate continuously in complex sea conditions (CCSB steel plate integral structure wind-wave impact load ≥50kN/m²);

Platform Emergency Repair: In the emergency repair of offshore platform equipment failures in the East China Sea, equipped with maintenance modules (hydraulic tools + testing equipment) and living cabins, providing operation platforms and accommodation support for repair teams. The CCSB deck steel plate has stable load-bearing performance and can carry 50-ton maintenance equipment for long-term operations.

Customization Services

Parameter & Function Customization: Adjust spud leg length (up to 100 meters) and module configuration according to operation scenarios (e.g., adding CCSB steel plate insulation layer for polar sea areas, upgrading anti-corrosion coating for high-temperature sea areas); for heavy-duty operation needs, the CCSB main load-bearing beam can be thickened to 50mm to improve platform load redundancy;

Value-Added Services: Assist in providing CCSB steel plate material certification (complying with CCS marine steel specifications) and platform classification certification (ABS/CCS/DNV); provide CCSB steel plate maintenance guidance (such as regular derusting, coating touch-up); connect with construction teams to provide "platform + module + operation and maintenance" integrated services, ensuring long-term stable operation of CCSB material platforms.
