Are you looking for a bulwark-mounted Panama chock? Please note that, according to international standards, the **Type A Deck Panama Chock** is specifically designed for deck installation. Is the Type A Panama chock deck-mounted or bulwark-mounted? The answer depends on the reference standard: ISO 13728 defines Type A as deck-mounted, while the older DIN 81915 standard may differ. To learn more about the differences, read our guide comparing Panama Chocks Type A and Type B, or click here to [buy bulwark-mounted mooring chocks] directly.

Standard Classifications & Clarification
Notes on Standard Classification: To ensure accurate procurement, please note the standard correspondences for Type A Deck Panama Chocks:
ISO and JIS Standards: In ISO 13728 and JIS F 2017, the terms “ISO 13728 Type A deck Panama chock” and “JIS F 2017 Type A deck Panama chock” explicitly refer to deck-mounted configurations.
DIN Standards: In the DIN 81915 standard, “Type A” refers to a bulwark-mounted configuration. Therefore, the equivalent deck-mounted types are *DIN 81915 Type C deck Panama chock (without horns) and DIN 81915 Type D deck Panama chock with horns.
GB Standards: We also supply *GB/T 11586 AC type / AP type Panama chocks for domestic and specific international shipyard projects.
Manufacturing Process & Material Options
OLIPORTS’ mooring deck chock products are available in two main manufacturing processes to meet different structural requirements:
Cast Steel Design: As a specialized manufacturer of *cast steel deck Panama chocks, we use high-quality carbon steel or alloy steel for casting. This provides exceptional strength and the ability to produce complex shapes for heavy-duty deck mooring chock applications.
Welded Design: For projects requiring faster lead times or specific modifications, our welded deck Panama chocks are fabricated from high-strength steel plates. We offer highly competitive *welded deck Panama chock prices without compromising on quality.
Technical Data: Panama Chock Dimensions, Weight & Drawing
Accurate Panama chock dimensions, drawings, and weight data are critical for shipyard deck layout design. Below is the standard specification table for our Type A Deck Panama Chock.
Technical Data Note: Differences in the dimensions and weights of Panama-class cable ports listed on various suppliers’ websites typically stem from confusion regarding different international standards (ISO vs. JIS vs. DIN) or manufacturing processes (casting vs. welding). To ensure 100% accuracy in your vessel’s deck layout, we have strictly categorized the technical data according to the following standards. Please select the table that matches your vessel’s specific design requirements.
- ISO 13728 Standard
(Type A – Deck-Mounted) - JIS F 2017 Standard
(Type AC—Deck-Mounted) - DIN 81915 Standard
(Type C – Deck Mounted, Without Horns) - GB/T 11586 Standard
(Type AC – Deck Mounted)
ISO standards primarily specify two core dimensions (310 mm and 360 mm), which are applicable to most international ocean-going vessels.
| Nominal Size (mm) | L (mm) | l1 (mm) | SWL (kN) | Approx. Weight (kg) |
|---|---|---|---|---|
| 310 | 310 | 720 | 471 | 257 |
| 360 | 360 | 770 | 775 | 286 |
The Japanese Industrial Standards (JIS) offer a wider range of sizes, ranging from 310 mm to 500 mm, and are commonly used on vessels built by Japanese shipowners or Japanese shipyards.
| Nominal Size (mm) | L (mm) | L1 (mm) | L2 (mm) | H1 (mm) | SWL (Ton) | Approx. Weight (kg) |
|---|---|---|---|---|---|---|
| 310 | 310 | 708 | 639 | 541 | 30 | 253 |
| 360 | 360 | 760 | 684 | 591 | 50 | 289 |
| 400 | 400 | 804 | 724 | 631 | 80 | 335 |
| 450 | 450 | 860 | 770 | 681 | 120 | 365 |
| 500 | 500 | 910 | 820 | 731 | 250 | 395 |
The naming and sizing systems used in German/European standards (DIN) are completely different from those in Asian standards. The deck-mounted type is referred to as Type C in DIN standards.
| Type | SWL (kN) | L (mm) | L1 (mm) | B (mm) | H (mm) | Approx. Weight (kg) |
|---|---|---|---|---|---|---|
| C2 | 20 | 315 | 360 | 160 | 115 | 29 |
| C3 | 30 | 390 | 450 | 200 | 140 | 45 |
| C4 | 40 | 460 | 530 | 240 | 165 | 68 |
| C5 | 60 | 540 | 620 | 280 | 190 | 95 |
Chinese National Standards (GB) are largely based on JIS standards, but there are slight differences in certain specific thicknesses and weights (generally, cast steel parts designed to Chinese National Standards are more optimized and slightly lighter).
| Nominal Size (mm) | L (mm) | L1 (mm) | L2 (mm) | H1 (mm) | Approx. Weight (kg) |
|---|---|---|---|---|---|
| 310 | 310 | 708 | 652 | 541 | 199 |
| 360 | 360 | 760 | 704 | 591 | 245 |
| 400 | 400 | 804 | 744 | 631 | 285 |
| 450 | 450 | 860 | 790 | 681 | 325 |
