🔍 Key Concepts

• Relationship between total weight, longitudinal moments (LM), and transverse moments (TM) when distributing reactions to multiple legs on a jack-up rig • How to find individual leg reactions by resolving total vertical force and transverse moment equilibrium • Sign convention for transverse moments (port vs starboard) and how a negative TM affects which side carries more load

💭 Think About

• Write the basic equilibrium equations: sum of vertical forces and sum of transverse moments, then think about how many legs share the total load • Ask yourself: how does a negative transverse moment influence whether the starboard leg reaction becomes larger or smaller than the simple total weight divided by number of legs? • Consider the geometry: how far is the starboard leg from the centerline, and how would you express the starboard leg reaction in terms of total weight and TM?

✅ Before You Answer

• Be sure you are dividing the total weight correctly among the legs based on symmetry before adding the TM effect • Confirm your moment arm distance used for the transverse moment is correct and consistently in feet, so TM (ft-kips) divided by distance (ft) gives kips • After calculating, check that the sum of all leg reactions equals the given total weight (21,401 kips) within rounding.
