Research Initiation Date (Award Date)
Research Performing Activity
EG&G Washington Analytical Services
Research Principal Investigator
Mr. David Dillon
Description

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.

Latest progress update

Complete. The author 'walks' the operations person through the step-by-step procedures he should take in evaluating the design of a spread mooring for a floating drilling rig.
