Overview:
Advantages of an Industry-wide Standard
– Enhanced interoperability among project participants
– Reduction of risks due to:
• Miscommunication
• Different terminologies
• Different methods of calculating risk
The Challenge of Collaboration
- No industry-wide anticollision standard
- Different standards define risk differently
– Differ in methods for evaluating/reducing risk
– Differ in amount of risk deemed acceptable
- A hybrid approach requires
– Careful planning
– Integration/bridging of methodologies
– Effective communication
– Team work
Case Study Offshore Qatar
- Different databases, software
– Contractor – proprietary software
– Operator – commercial software
- Advantage in catching potential errors
– Incorrect survey entered
– Missing survey
– Incorrect sidetrack point
– Incorrect rotary table elevation
– Incorrect survey tool model assigned
- Resolving Differences in Anticollision Standards
– Extensive pre-job planning to identify potential issues
– Established plan to meet both companies’ standards
– Followed both company and operator’s rules for exemptions
– Independent calculations performed throughout execution
– No actions that would pose HSE risks
