When planning the lift of project cargo, what detailed engineering survey is absolutely essential, and why?

When planning the lift of project cargo, a detailed structural integrity survey of the lifting points and the cargo itself is absolutely essential because it verifies the load-bearing capacity and identifies potential weaknesses that could lead to catastrophic failure during the lift. This survey involves a thorough inspection and, if necessary, non-destructive testing (NDT) methods like ultrasonic testing or radiographic testing to assess the internal condition of the lifting points, welds, and structural members. Project cargo, by its nature, is often oversized and overweight, placing immense stress on lifting equipment and the cargo's own structure. The structural integrity survey confirms that the lifting points are capable of withstanding the anticipated loads, considering factors like the angle of lift, dynamic loading due to movement, and any pre-existing corrosion or damage. Without this survey, there is a significant risk of the lifting points failing, causing the cargo to drop, which could result in severe damage to the cargo, the lifting equipment, and potential injury or loss of life. Furthermore, the survey ensures that the cargo itself is structurally sound enough to withstand the forces imposed during the lift, preventing deformation or collapse. The engineering survey provides documented evidence of the structural capacity, allowing for informed decisions regarding lifting methods, equipment selection, and necessary reinforcement or repairs before the lift commences. Therefore, this detailed assessment is not just recommended, it is a critical prerequisite for ensuring a safe and successful lifting operation.
