🔍 Key Concepts

• Environmental forces affecting a MODU (wind, waves, current) and how their direction can change over time • Purpose of a symmetric mooring pattern around a MODU • How load sharing works in multiple mooring lines

💭 Think About

• Think about how conditions at an offshore location might change over days or weeks. Will forces likely stay from one direction, or shift? • Consider what a symmetric pattern around the MODU allows you to do when the direction of the combined environmental forces changes. • Ask yourself: in a symmetric pattern, do all lines always work equally, or do certain lines become more heavily loaded depending on the direction of the forces?

✅ Before You Answer

• Verify whether regulations actually mandate symmetric patterns, or if they are mainly an engineering choice. • Check which option best reflects the real behavior of environmental forces offshore over long periods. • Confirm whether it is realistic that all lines always contribute equally to holding power, or if some will carry more load depending on force direction.
