HAIDING SHIPYARD Sectional jack up barge is a heavy-duty modular equipment designed for 3-100m marine water depth, with spud leg design length of 10-150m and total platform load capacity of 3000 tons, covering eight types: geological exploration, hoisting, excavation, maintenance, general operation, drilling, wind farm installation and living quarter. Aiming at the pain points of deep-sea engineering such as "large load demand, multi-scenario adaptation and complex environment operation", it achieves full water depth coverage from shallow sea to deep sea (3-100m) through sectional truss spud legs (up to 150m long), hydraulic rack-and-pinion lifting system (3000 tons load capacity) and modular functional cabins. It can complete high-end operations such as geological sampling, wind power hoisting, marine drilling and platform maintenance, with platform full-load leveling accuracy of ±0.1° and wind resistance grade up to 12, providing a "one-stop, full-functional, high-stability" operation carrier for marine engineering.

Product Advantages and Features

1.Ultra-high Load Design: The total platform load capacity reaches 3000 tons, deck uniform load ≥80kN/㎡, and local concentrated load can bear 500 tons (adapted to large drilling equipment and wind turbine main engine hoisting), far exceeding traditional jack-up platforms (load ≤1500 tons);

2.Full Water Depth Coverage: Adapted to 3-100m water depth operations, spud legs adopt sectional truss structure with customizable length of 10-150m, insertion depth into seabed ≥8m, and can stably berth in shallow sea (3-20m), medium sea (20-50m) and deep sea (50-100m). The spud can contact area ≥50㎡ (preventing sinking into soft soil layer).

3.Full Coverage of Eight Functional Types: Geological exploration, hoisting, excavation, maintenance, general operation, drilling, wind farm installation and living quarter platforms can be customized according to operation needs. Functional cabin modules (exploration cabin, hoisting cabin, drilling cabin) can be quickly disassembled and assembled, and a single platform can switch more than 3 operation modes;

4.Special Equipment Integration: Wind farm installation platform can be equipped with 800-ton marine crane (360° slewing), drilling platform with 5000m deep well drill, and living quarter platform can accommodate 100 people (including dormitory, canteen and office area), realizing integration of "construction + living + storage".

5.Sectional Transportation & Assembly: The platform is split into 5-8 sections (main platform section, spud leg section, functional cabin section), with maximum single section weight ≤100 tons, which can be transported by semi-submersible ships and ocean-going barges for deployment in global sea areas; on-site assembly is completed with flanges + prestressed bolts and marine floating cranes, with assembly cycle ≤15 days;

6.Modular Maintenance: Core components (lifting cylinders, cranes, drills) adopt modular design, which can be disassembled and replaced as a whole in case of failure, reducing maintenance time to 12 hours/time; the spud leg rack is made of wear-resistant alloy steel (hardness ≥400HB) with a service life ≥20 years in deep-sea environment.
