Posidonia openable Panama chock

The Posidonia openable Panama chock is the result of an advanced engineering project, developed to meet the needs of a military sector client. The challenge was to design a Panama chock capable of accommodating even the most oversized sockets, without compromising available deck space or increasing the vessel's weight.

Key Features:

  • Custom Design: This openable Panama chock is specifically designed to allow the passage of sockets of various sizes, ensuring maximum operational flexibility for military vessels that need to interact with different ships and equipment.
  • Compact Size and Maximum Functionality: Although compact and designed to accommodate the largest mooring lines, the innovative design allows the chock to be closed after the socket has passed through, maintaining a high level of safety during operations.
  • RINA Certification: This product complies with stringent international standards and is RINA-certified.

Technical Innovations:

  • Re-engineering of DIN 81915 Standard: While based on this international standard, the Posidonia openable Panama chock has been redesigned to offer a significantly higher SWL (safe working load), currently the highest globally.
  • High-Quality Materials: Fabricated from Duplex steel (but also available in standard alloy steel), the openable Panama chock is constructed using welded tubes and plates, ensuring superior quality compared to cast models.
  • IMO 1175 Certification: Our Panama chocks comply with all regulations required for use in complex and specific marine environments.

Posidonia openable Panama chock - Operational Advantages:

  • Top-Opening Design: This feature allows for easy passage of large-diameter sockets and quick closure of the equipment without compromising operational safety.
  • Three Sizes Available: The Posidonia openable Panama chock is available in three variants with SWL capacities of 45T, 110T, and 150T, meeting a variety of operational requirements. Thanks to our in-house engineering team, we can customize and produce solutions according to specific client needs.
  • Adopted by European Naval Forces: This unique model is already in use and has become the standard for several European naval forces.

Quality and Controls:

All of our products undergo stringent quality controls, including testing on our internal pull test bench. Welding is performed by certified personnel and inspected using non-destructive testing methods, ensuring a reliable and safe product even under the most critical conditions.

Manufacturing is carried out at our facility in Novi Ligure, Italy, ensuring full compliance with all European quality standards. The Posidonia openable Panama chock exemplifies engineering excellence in the military marine sector, combining innovation with safety. Its flexibility and durability have made it the standard for many European naval fleets, reinforcing Posidonia’s position as a global leader in deck equipment.
