Over the last several months, we’ve reviewed the most important skills that riggers need to bring to the table in the shipyard and other shipping applications. Now, we want to discuss how math and calculations impact the job and why it’s important that riggers master these skills. A skilled rigger needs to have not only basic knowledge of math but more advanced experience as well. Here are some of the things to consider in terms of math.
Beyond Basic Math Skills
Basic math is a good starting point for anyone who wants to work in a shipyard, but that isn’t all that riggers need to know. There will be aspects of algebra, geometry, and even calculus when dealing with the measurements and calculations for rigging. If you think you may want to pursue a career as a rigger, take additional math classes to brush up.
Riggers have to always think in three dimensions. To ensure that an overhead lift is being performed safely and accurately, you need to run the calculations without any mistakes. This includes the weight of the items being moved, the weight of the rigging itself, the maneuvers necessary, and the people involved.
Along with weight, you also need to be able to understand the measurements of the items. This can be simple, in the case of shipping containers, or it can be quite difficult when you’re looking at large fabricated ship parts that need to be maneuvered carefully into place. Measurements will need to be calculated with extreme accuracy.
Rigging is also about spatial relations. Knowing that two objects can’t occupy the same space is just a fraction of what needs to be determined when you’re measuring and calculating the process of rigging and lifting. Understand the basic math, along with the more complicated calculations and measures, will be essential to success.
You can obtain these skills through experience, education, or working with a mentor who can help you better understand the process of becoming a rigger.
