TLS Offshore containers follow DNV2.7-1 standard to do test for offshore containers, the container should be lifted with a sling at a certain angle in the vertical direction according to the specification of DNV2.7-1.
ALL POINT LIFTING TEST:
The weight (2.5R-T) is placed inside the box and the deformation of the bottom frame is measured simultaneously. After 5 minutes of static lifting of the container, measure the deformation of the bottom frame.
2- point LIFTING TEST:
Reduce the weight inside the box to (1.5R-T), and measure the deformation of the bottom frame.
FORK POCKET LIFTING TEST(If the container has pockets):
Adjust the weight inside the box to (1.6R-T), and measure the deformation of the bottom frame at the same time. Fix the fork arm with angle pieces or jack the container up and stand still for 5 minutes, then measure the line variation of the bottom frame (for the small container, directly lift the container with forklift and stand still for 5 minutes, then test and record the data).
VERTICAL IMPACT TEST: Adjust the weight in the container to R-T state.
Appropriate Shackle and Wire Rope Sling should be installed on the four lifting points according to the design requirements of the drawing, and the lifting point of the Wire Rope should be adjusted appropriately to confirm that the container has a certain slope, and then the container should be unloaded quickly between the hook of the crane and the Wire Rope, and the container should be pulled by the Rope during lifting to prevent the container from swinging randomly.
Lift the container to the cement surface, adjust the tilt angle of the bottom side beam of the box by 5° (ensure that the highest point of the bottom frame can't be higher than the lowest point 400 mm), and ensure that the lowest point of the bottom frame of the container is more than 5 cm free naked distance from the ground to operate quick shackle, so that the container free fall.
Inspect all structural parts of the container for cracks or damage immediately after the drop sample is completed.
