2.5 PDH certificates will be issued after the presentation. If you have more than one person viewing these webinars at your location, you can request additional PDH certificates for $10 at the email above.
Webinar Session Program:
|8:10AM CDT||Accident Record
Speaker: Mr. Bob Jack (DNV, Noble Denton Marine Services)This presentation sets the scene for the webinar. It shows how foundation accidents fit into the overall jack-up accident regime and how they have changed with time to become one of the major causes of losses and deaths on jack-ups and lift boats. The causes and possible ways to reduce their effects are suggested. The relationship with jacking system failures, which tend to have very similar results is explored.
|8:30AM CDT||Geophysical Site Evaluation
Speaker: Mr. Andy Hill (BP)
|8:50AM CDT||Geotechnical Assessments
Speaker: Mr. David Menzies (Matthews Daniel)- Jack-Up Rigs
– Data for Assessment
– Methods of Analyses
– Problem Soil Conditions
– Foundation Risk Management
– Foundation Case Histories
|9:10AM CDT||Mechanical Aspects
Speaker: Mr. Mike Dowdy- Punch-thru load case
– Leg & jacking system design evolution has increased consequences of punch-thru
– Some Jacking system control technology has improved ability to monitor and recover RPD
– Immediate response actions
– Dumping preload rapidly – better dumping systems
– Jacking during the event can make things worse
– Designers should include nominal punch-thru load cases in leg design and specify RPD and/or punch-thru elastic limits
– Deep penetration leg pulling is another critical load case
|9:30AM CDT||Panel Q&A Session|
