Boatswain’s Mate Chief (BMC) SWE Practice Exam

When a lifting system is newly installed or has been structurally repaired or overhauled, you verify its strength by applying a static overload and holding it. The specified test uses 200% of the Working Load Limit and is held for at least 10 minutes. Because the load is applied statically and held, this checks the structure’s ability to carry a significant overload without permanent deformation, cracking, or excessive deflection, confirming a safe margin beyond the normal working load. This is distinct from tests that cycle loads or focus on function in operation or acceptance criteria, which serve different purposes.
