Approved Continuous Examination Program (ACEP)

An Approved Continuous Examination Program is one of two container safety examination schemes allowed under the CSC. A national administration approves it if the owner shows it gives a standard of safety not below the periodic scheme. The container is inspected as part of normal operation instead of on a fixed calendar.

Why it matters

ACEP lets container owners, usually large lessors and lines, examine boxes when they pass through depots rather than pull them out on a set date. Containers in an ACEP must be inspected at least as often as the periodic scheme requires. The ACEP number shows on the CSC plate, often as a decal. Administrations review programs at least every 10 years. BIC runs a global ACEP database. For a portable storage operator, an ACEP number on a purchased unit tells you which owner program covered it. A common mistake is to think the number guarantees the unit is in good shape today. Ask for recent inspection records.
