🔍 Key Concepts

• Natural roll period of a vessel or platform and how it relates to safety when going on location • Relationship between roll amplitude (in degrees) and acceptable roll period limits • Typical time scales for roll motions of large offshore units like COASTAL DRILLER in 150 feet water depth

💭 Think About

• Think about whether a large offshore unit can realistically complete a full roll in fractions of a second, or if its motions are usually measured in several seconds per roll • Consider what a 1° single amplitude roll angle suggests about the platform’s motion: is that a small, moderate, or large motion, and would you expect a longer or shorter safe roll period? • Compare the answer choices to what you know about typical roll periods of ships versus large drilling units—are they generally closer to a few seconds, many seconds, or tenths of a second?

✅ Before You Answer

• Eliminate any options that are clearly not realistic for the size and mass of an offshore drilling unit in 150 ft of water • Check which options represent a practically meaningful roll period for planning safe operations when going on location • Verify in your stability/offshore operations notes what range of roll periods is commonly associated with comfortable, safe motions for large platforms
