Core application areas
1. Large bulk cargo/container terminal: capable of withstanding mooring forces up to 200 tons, suitable for berthing and mooring vessels of 100000 to 200000 tons
2. Oil and gas/LNG dedicated terminal: resistant to salt spray and corrosion, meeting the long-term stable operation requirements of high-risk working conditions
3. Offshore engineering platforms/shipyards: dedicated for deck anchoring and temporary mooring of operational vessels
4. Inland ports/yacht docks: Compact double column structure, suitable for efficient storage of cables in narrow berth spaces
5. Global port upgrading and renovation: replacing old single column mooring bollards, improving mooring safety and operational efficiency
Core performance parameters
Material: Cast steel (ZG230-450/ZG340-640), with a tensile strength of ≥ 450MPa, far exceeding the corrosion resistance of ordinary cast iron by three times
Load range: SWL 10-320kN (1-32 tons), customized up to 200 ton level
Force angle: horizontal ± 180 °, vertical+60 °/-15 °, shared by multiple cables without interfering with adjacent mooring
Anti corrosion treatment: sandblasting Sa2.5 level+double-layer anti rust primer+topcoat, salt spray environment service life ≥ 20 years
Installation configuration: Standard 8-10 sets of high-strength anchor bolts (4.8-8.8 grade galvanized), supporting concrete filling and reinforcement
Cast steel double column mooring bollard - a core component for dock mooring safety
This cast steel double column mooring post (also known as double column mooring post or double horn mooring post) is made of high-strength cast steel and is designed with a symmetrical double column structure. It is the core equipment for port terminals and ship deck mooring. Compared with traditional single column mooring posts, it has stronger bearing capacity, more efficient cable storage, and more reasonable space occupation.
✅ Core advantages of the product
★Super strong material guarantee: Selected high-quality cast steel (ZG230-450/ZG340-640), with tensile strength and impact resistance superior to ductile iron, salt spray corrosion resistance, wave impact resistance, and stable operation for more than 20 years under harsh sea conditions
★ Efficient mooring design: The double column independent load-bearing structure can accommodate multiple cables at the same time, avoiding cable entanglement and "climbing". It is adaptable to all angles, including horizontal ± 180 °, vertical+60 °/-15 °, to meet the mooring and mooring needs of various ships
★ Self owned factory customization: The source factory has no intermediaries and supports full dimensional customization of size, load-bearing level, anti-corrosion coating, and bolt specifications. The base size and load-bearing structure can be adjusted as needed to adapt to different tonnage ships and dock conditions
★ Complete compliance certification: Strictly following international standards such as ISO 13795 and DIN 82607, certified by classification societies such as CCS, ABS, BV, DNV, etc., the quality meets global port procurement requirements
★ Easy installation and maintenance: Standardized base reserved hole positions, compatible with various dock foundation structures, bolt fixation and quick installation; Anti corrosion coating eliminates frequent maintenance and reduces long-term usage costs
✅ Full coverage of applicable scenarios ✅ Bulk cargo terminal, container berth, roll on/roll off ship terminal ✅ Oil and gas terminals, LNG dedicated ports, offshore operation platforms ✅ Repairing shipyard deck fastening and inland cargo terminal ✅ Yacht marina, leisure port, small vessel docking area
✅ Customized service support ✅ Draw construction drawings as needed, accurately match dock/ship parameters ✅ Customize different load-bearing levels (10-320kN), suitable for ships of 50000-200000 tons ✅ Optional concrete filling reinforcement, special anti-corrosion coating (such as heavy-duty anti-corrosion epoxy coating) ✅ Bulk spot supply+expedited customization, supporting global port and shipowner bulk order delivery
✅ Factory exclusive customization service
Customize exclusive self weight and safe load specifications based on ship tonnage and port stress requirements
Adjust the spacing between double columns, pile height, base plate size, and installation bolt hole position as needed
Optional concrete pouring weighting, special thickening anti-corrosion coating, customized non-standard irregular structure
Bulk spot supply+urgent customized orders, long-term undertaking of bulk foreign trade orders for global shipowners and port engineering
