Container Securing Equipment Tension Pressure Elements BF-B1
— High-Strength Tension & Compression Connector for Ship Structures —
Product Overview
The Tension Pressure Element Bulkhead is a high-strength marine fitting designed for container securing and support systems on vessels and offshore platforms.
Container lashing equipment of tension pressure elements refer to the process of firmly attaching cargo to the structure using various fasteners. The common purpose of fasteners is to establish a reliable and secure connection between two objects. They are available in a variety of shapes, sizes, and materials.
Screws are one of the most common fasteners, available in both standard and metric sizes. Materials used for manufacturing screws include steel, brass, aluminum, and plastic. They are typically used to connect metal components or secure wooden parts.
OLIPORTS high-quality shipping container twist locks meet international standards and undergo rigorous testing to guarantee optimal performance even in the harshest environments. Whether you’re looking for standard models or heavy-duty solutions, we provide reliable container locking devices for all your cargo transportation needs.
Working Principle
During vessel operation, the stacked containers generate vertical and horizontal forces.
The Tension Pressure Element Bulkhead functions as a force transmission bridge, transferring loads evenly between the container foundation and the ship’s bulkhead.
Toothed slots provide multiple locking positions for adjustment.
The central key block ensures accurate alignment and prevents movement.
The component transfers compression downward and resists tension and vibration during ship motion.
This ensures safe, stable, and long-lasting container stacking on vessels.

- Interchangeable Compatibility: Fits standard bulkhead fittings such as AN-A1 / AN-A2 counter bearings.
- Flexible Adjustment & Adaptation: The modular structural design supports flexible adjustment based on cargo size and shape, adapting to different lashing requirements and enabling efficient “one-element multi-scenario” application.
- Weldable & Class Approved: Meets ABS, DNV-GL, CCS, and ISO standards
Application
The Tension Pressure Element Bulkhead is widely used in container shipping (securing cargo inside general cargo and hazardous material containers), heavy equipment land transportation (full-vehicle lashing of construction machinery and industrial equipment), and multimodal transport (transit securing of goods in sea-land and land-air intermodal shipments), it serves multiple industries including logistics, shipping, construction, and industrial manufacturing.
Typical Applications Include:
- Structural reinforcement for ship bulkheads and foundations
- Container stacking and securing systems inside cargo holds
- Hatch cover support and container base locking systems
- Port terminal container alignment frames and handling bases
- Offshore platform equipment foundations and cargo securing points
With its high tensile strength, corrosion-resistant finish, and standardized connection design, this part is trusted by global shipping lines, shipyards, port operators, and marine service providers. By choosing OLIPORTS as your supplier, you ensure reliable performance, compliance with ISO & class society standards, and consistent availability for both scheduled maintenance and large-scale fleet projects.
Combination with Other Fittings
- Support Shoe (AN-A1 / AN-A2 Series): Installed at the base or opposite side of bulkhead elements to absorb reaction forces and evenly distribute loads.
- Counter Bearing / Half AN-A2: Used with tension/compression elements to provide structural support and precise alignment, ensuring stable load transfer.
- Base Foundation Fittings: Interface components connecting the container base to the ship’s deck or hold structure.
- Operating Rod System for Container Twistlocks: Enables mechanical linkage or remote operation for container locking and unlocking.
- Turnbuckle Lashing Rods & D-Ring Lashing Fittings: Provide lateral restraint and additional stability to prevent shifting of the cargo structure under dynamic loads.
All components listed above can be customized in terms of dimensions, coatings, and materials according to project drawings to ensure full compatibility with existing bulkhead systems or container securing systems.
