🔍 Key Concepts

• Mooring system components and what part actually feels the tension from waves, wind, and current • Difference between measuring depth, position, stability, and load/tension • Common devices used to monitor line tension or force in structural members

💭 Think About

• Ask yourself: which option sounds like it directly measures force or tension in a single leg or line, not depth, not position, and not overall stability calculations? • Think about where you would place such a device: would it be on the mooring line itself, on navigation equipment, or inside a computer program? • Match each choice to its primary purpose offshore: does it mainly track hole/rig position, water depth, weight/force in a line, or vessel/rig stability?

✅ Before You Answer

• Eliminate any option that is mainly for measuring water depth or seafloor profile. • Eliminate any option that is mainly used for position reference of the rig or drill string, not for force in a line. • Focus on the choice whose main function is to sense and report tension/force in a structural member or cable.
