Webinar Session Program:
8:00AM CDT SUT-US Introduction
Speaker: Mr. Jack Templeton, SAGE USA, Inc.
8:05AM CDT IADC Introduction
Speaker: Mr. Mike DuBose, International Association of Drilling Contractors (IADC)
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

Geophysical site investigation of jack-up rig sites is critical to the overall safety of drilling operations. Selection of the appropriate tools to be able to define seabed and foundation zone conditions needs careful thought to deliver appropriate imagery on a site specific basis. Choice of shallow profiling equipment especially needs careful thought to  ensure imaging to an appropriate depth below seabed to define the potential soil stratigraphy and avoid features, such as buried channels, ahead of subsequent geotechnical borehole evaluation. Inappropriate imaging may lead to late surprises and a need to move location late in the well design process or unforeseen conditions leading to variable leg penetration or punch through.
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, OE Consulting, LLC

- 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
Speakers: Mr. Jack Templeton, SAGE USA, Inc.
10:00AM CDT Closing
Speakers: Mr. Kerry Campbell, Consultant
