🔍 Key Concepts

• Environmental loading refers to natural forces acting on a vessel or offshore structure • Think about what normally moves water or creates steady force on a hull besides wind and waves • Distinguish between natural environmental forces and human/operational activities like drilling

💭 Think About

• Which choice regularly acts on a vessel or structure in the marine environment, even when no work is being done? • Which options are truly "environmental" (from nature) versus related to equipment, operations, or material behavior? • Which of these forces would a naval architect or marine engineer routinely include along with wind and waves in stability and mooring calculations?

✅ Before You Answer

• Make sure your choice is a natural, continuous environmental force in the water, not an industrial activity • Ask whether the force directly comes from the ocean/sea itself rather than from machinery or structural material properties • Eliminate any options that depend on specific operations (like work being performed) instead of always-present marine conditions
