General requirements for offshore container lifting test

11/18/2022

 
  1. Offshore containers shall be tested according to the requirements of four-point lifting and two-point lifting respectively.
  2. During the lifting test, the lifting angle should be the design angle.
  3. The lifting process should be carried out smoothly to avoid obvious inertial load.
  4. The deformation measurement of the beam and the integrity inspection of the offshore container should be carried out after keeping the lifting state for 5 minutes.
   
   FOUR-POINT LIFTING
  1. When lifting, a uniform load equivalent to 2.5R-T should be placed in the box.
  2. During the test, the deformation of the beam should not exceed 1/300 of the beam span. After the test, the container shall not show significant permanent deformation or damage.
   
​    TWO-POINT LIFTING (DIAGONAL LIFTING TEST)
  1. Select two lifting lugs at diagonal positions for lifting. When lifting, a uniform load equivalent to 1.5R-T should be placed in the container.
  2. If the container is not geometrically symmetrical, the lifting test shall be carried out on the two diagonal corners respectively.
  3. After the test, the container shall show no obvious permanent deformation or damage.
 
R - maximum allowable total mass of offshore container and loaded cargo (without spreader)
T - Empty mass of offshore container including attachments (without spreader)
The TLS containers will not promote the next production step until the lifting test is passed.
