Container compressive capacity test: vertical impact test done by tls offshore containers int.

3/6/2023

 
The Container Compressive Capacity Test, also referred to as the Vertical Impact Test, is a widely used method for evaluating the safety performance of containers during transportation. This test is specifically designed to determine the compressive capacity of containers when subjected to vertical impact. The following testing criteria are strictly adhered to:
  1. The container is loaded with a uniformly distributed load equivalent to its rated weight, exclusive of the spreader, as well as the mass of the empty container along with its attachments, excluding the spreader. The load is then securely fastened.
  2. The testing is conducted on a flat concrete floor or any other hard ground, with wooden boards not exceeding a thickness of 50mm allowed to be placed on the ground.
  3. The container is tilted and lifted to an angle not less than 5° between the side beams and end beams connected to the lowest corner on the bottom of the container and the ground. The height difference between the lowest and highest corner points on the bottom surface of the container should not exceed 400mm.
  4. The lowest corner point of the container with the weakest stiffness is selected as the point of impact during the test.
  5. The container's initial impact velocity when touching the ground should not be less than 1m/s, and its lowest corner should be at least 50mm above the ground.
  6. Upon completion of the test, the container should not display any significant permanent deformation or damage, while minor repairable open welds and deformations are permitted.

TLS Offshore Containers Int. ensures that all of its products are meticulously produced and tested in strict compliance with international standards.

Lifting devices for offshore containers

9/23/2022

 
Unlike ordinary dry cargo containers, which are primarily used for land transportation, offshore containers are specialized containers used on offshore oil rigs;  Therefore, there is a well-established set of European standards for their design and manufacture, including DNV 2.7-1 and EN 12079.
Marine containers are mainly used on marine drilling platforms, where the operating environment is demanding and frequent hoisting is required, which places high requirements on container hoisting equipment.
All four corners of the top of the container have a top corner piece structure. The top corner piece structure consists of a standard container top corner piece, a lifting lug, and a reinforcing piece.
The uplifted ears are located on the inner side of the top horn, adjacent to it, and are arranged and fixed to it. The four-point or two-point lifting of a container can be performed by means of a hoist, and therefore there is a higher strength requirement on the hoist itself as well as on the top of the box in which the hoist is mounted. The lifted lug material must have low-temperature shock resistance properties.
The reinforcing piece consists of a bottom plate for the lifting lug, and a coaming plate arranged on three sides of the bottom plate of the lifting lug. The setting of the coaming plate not only strengthens the lifting ear area but also protects the lifting ear.
When lifted, a special sling is used, the shackles are passed through the eye holes and locked firmly, then the sling is lifted through the main ring of the sling.

WHAT BASIC TESTS WILL THE FACTORY DO BEFORE THE CONTAINER DELIVERY?

1/21/2022

 

1 WELDING INSPECTION
Welding inspection of containers, including inspection and NDT.
The whole inspection process runs through the manufacturing process of containers, not limited to the final product, and adjusts production at any time to ensure welding quality.
 
2 LIFTING TEST
In addition to the test required by international container safety convention, our company will also carry out a two-point and four-point lifting test.
The two-point lifting test mainly tests the anti-deformation ability of containers at sea under extreme conditions, and the four-point lifting test mainly tests the carrying capacity of containers at sea. Both tests do not allow permanent deformation of containers at sea during accelerated crane lifting.
 
3 DROP TEST
The main purpose of the drop test is to examine the impact of the lifting and placing of containers at sea to ensure that the cabinet can withstand the damage caused by the impact.
 
4. WATER TIGHTNESS TEST
The container body is sprayed with high-pressure water from all directions, and will be checked in all directions after spraying to ensure that there is no water in it.
