Heavy-Duty marine mooring equipment
OLIPORTS offers high-strength cast steel Panama chock solutions that fully comply with the latest regulations of the Panama Canal Authority (ACP). Designed specifically for the mooring of heavy-duty container vessels and global ocean-going fleets.
The critical role of marine Panama chocks in ship mooring operations cannot be overlooked. They must withstand enormous tensile loads, particularly when passing through canal locks where ships are pulled by locomotives. As a leading manufacturer of Panama chocks in China, OLIPORTS designs and manufactures high-quality marine Panama chocks capable of withstanding extreme axial and shear stresses.
Whether used for standard container vessel mooring or specialized merchant ships, every Panama chock OLIPORTS manufacture features an optimized inner surface curvature. This advanced design minimizes rope friction, thereby significantly extending the service life of heavy-duty steel wire ropes and modern synthetic ropes.
Choose Your Mounting Configuration
To simplify your purchasing process, we have categorized our products by installation method. Click the links below to explore the detailed technical subpages:
Type A – Deck Mounted Panama Chock
Features a heavy-duty cast steel base that can be welded directly to the main deck. Ideal for deck areas without bulwarks or situations where mooring lines require increased clearance from the ground.
Complies with standards: JIS F2017 Type BC/BCX, ISO 13729 Deck Type, DIN 81915 Type C/D.
Type B – Bulwark Mounted Panama Chock
Designed specifically for direct embedding and welding into ship side panels. This space-saving design provides unobstructed guidance for mooring lines while maintaining the structural integrity of the hull.
Complies with standards: JIS F2017 Type AC/ACX, ISO 13729 Side Panel Type, DIN 81915 Type A/B
Universal Standards Covered by OLIPORTS
OLIPORTS not only offer standard Panama chocks for sale, but also ensure precise engineering compliance. Below is an overview of the major international design standards for the products manufactured at our foundry:
| Design Standard | Main Models | Target Market / Application | Key Advantage |
|---|---|---|---|
| JIS Standard | JIS F2017 Type AC & BC | East Asian shipyards (China, Japan, South Korea) | Traditional durability and excellent value for money for steel wire ropes. |
| ISO Standard | ISO 13729 Bulwark & Deck | Modern VLCCs (Very Large Crude Carriers) and ultra-large container ships) | The increased inner arc radius is ideal for high-end synthetic ropes. |
| DIN Standard | DIN 81915 Type A, B, C, D | European shipowners, specialized dredgers | The dimensions are extremely precise, ensuring a very high safety margin even in rough sea conditions. |
Need a Custom Panama Chock?
At OLIPORTS, we understand that no two ship structures—whether converted or newly built—are exactly alike. If standard off-the-shelf specifications do not meet your shipyard’s construction constraints, we can provide rapid solutions for custom Panama chocks.
Customized Base Design: Height and base geometry can be adjusted to match your specific under-deck structural reinforcement plan.
Extra-Large Nominal Sizes: With the capability to manufacture custom components with SWL (Safe Working Load) ratings exceeding 140 tons and up to 250 tons, these are specifically designed for ultra-large transport vessels.
