Student registrations are only valid using ‘.edu’ or corresponding institutional email domains. Connections are unique and should only be used by one person. Duplicate connection will be forced out of the webinar session by the organizers.

Professional Development Hour Certificates:
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:

8:00AM CDT Introduction
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
10:00AM CDT
