DNV-ST-E271 : 2.7-1 Offshore Containers
DNV 2.7-1 Standard for Certification is a written standard for structural design, fabrication and testing of CCU used to move cargo in a container with a certified lifting sling.  DNV 2.7-1 is applicable to container shaped transportation units used for repeated handling in offshore environment with gross weight less than or equal to 25,000 kg.

DNV 2.7-1 certification should be issued by widely accepted competent authorities.
