Rig Mooring Reliability

The development of a handbook or guide for MMS operations personnel to assess the integrity of drill rig mooring systems. The guide will be both practical and analytical. Robert Walden of Woods Hole Oceanographic Institution will compile and edit the practical section which will address tests and inspections of mooring components and discuss equipment service life. David Dillon will discuss the strengths and limitations of system loadings. In addition, he will present a simplified example analysis which operations personnel can use to verify the adequacy of mooring designs.
