🔍 Key Concepts

• Catenary curve of an anchor line and how the line length compares to water depth • Relationship between anchor line tension and how much of the line is lifted off the bottom • Typical scope ratios (line length to depth) for deepwater mooring

💭 Think About

• How does increasing tension in the anchor line affect how much chain lies on the seabed versus how much is suspended? • Is the total catenary length usually just a little more than the water depth, or significantly more, in deepwater mooring? • Given 600 feet of water and a fairly high line tension (170 kips), which answers seem unrealistically short or long for the resulting catenary?

✅ Before You Answer

• Compare each choice to the 600-foot depth and decide if the implied scope (length ÷ depth) makes sense for a tensioned deepwater line • Think about whether very low scope (close to 1:1) is realistic under 170-kip tension for a mobile offshore drilling unit • Eliminate any options that would imply an obviously unreasonable scope for a tensioned anchor line in 600 feet of water
