Exercise:
Scenario:
You are managing a pipeline construction project. The activity "Laying Pipeline" is dependent on the activity "Clearing Right-of-Way." The "Clearing Right-of-Way" activity is expected to take 6 weeks. However, there is a high probability that it could be delayed due to environmental permitting issues. The "Laying Pipeline" activity is expected to take 4 weeks.
Task:
- Define the "Laying Pipeline" activity as a discontinuous activity. Explain your reasoning.
- Identify potential delays that could impact the "Laying Pipeline" activity.
- Develop a plan to manage these potential delays.
Exercice Correction
Here's a possible solution to the exercise:
1. **Define the "Laying Pipeline" activity as a discontinuous activity.**
Reasoning: The "Laying Pipeline" activity is dependent on the "Clearing Right-of-Way," which could be delayed due to permitting issues. By defining "Laying Pipeline" as a discontinuous activity, we can allow for a gap in execution to accommodate the potential delay in the "Clearing Right-of-Way." This will prevent unnecessary downtime and resource idle time while waiting for the right-of-way to be cleared.
2. **Potential Delays:**
- Environmental permitting delays
- Unexpected environmental discoveries requiring further assessment
- Weather delays
- Equipment availability issues
3. **Plan to Manage Delays:**
- **Communication:** Regularly communicate with stakeholders about the discontinuous nature of the "Laying Pipeline" activity and potential delays. Provide updates on the progress of the "Clearing Right-of-Way" and the expected start date for "Laying Pipeline."
- **Contingency Planning:** Develop contingency plans for each potential delay. For example, if weather delays are anticipated, have backup equipment and crews ready to continue work in favorable conditions. If permitting delays are expected, explore alternative routes or methods for clearing the right-of-way.
- **Resource Allocation:** Monitor resource availability and allocate resources efficiently to ensure they are available when needed. This might involve temporarily assigning resources to other tasks while waiting for the "Clearing Right-of-Way" to be completed.
- **Monitoring:** Closely monitor the progress of both the "Clearing Right-of-Way" and the "Laying Pipeline" activities to identify potential delays early and take corrective action.
Techniques
Chapter 1: Techniques for Managing Discontinuous Activities
This chapter delves into the specific techniques used to effectively manage discontinuous activities in oil & gas projects.
1.1 Calendar-Based Scheduling:
- Concept: This technique utilizes project management software to set specific start and end dates for the discontinuous activity, taking into account the anticipated breaks or interruptions.
- Example: If a well drilling activity is scheduled to start on June 1st but is expected to be interrupted for two weeks due to equipment delivery, the software can be used to schedule the activity to resume on June 15th.
- Pros: Offers clear visual representation of the activity's duration, breaks, and dependencies.
- Cons: Requires accurate prediction of break duration, which can be challenging.
1.2 Milestone-Based Scheduling:
- Concept: This technique focuses on key milestones within the discontinuous activity, rather than continuous duration.
- Example: Instead of defining the entire well drilling activity as a discontinuous activity, it can be broken down into milestones: "Rig Setup", "Initial Drilling", "Equipment Replacement", "Final Drilling". Each milestone can be scheduled with defined start and end dates.
- Pros: Provides flexibility in managing individual phases within the activity.
- Cons: Requires meticulous planning and coordination across different teams involved in each milestone.
1.3 Contingency Buffering:
- Concept: Incorporating buffer periods within the schedule to account for potential disruptions or delays in discontinuous activities.
- Example: When scheduling a pipeline laying activity, a buffer of two weeks can be added after the "Right-of-Way Clearing" milestone to accommodate potential delays.
- Pros: Offers a safety net for unexpected interruptions.
- Cons: Can lead to overestimated project durations if buffers are not managed carefully.
1.4 Resource Allocation Optimization:
- Concept: Adjusting resource allocation based on the planned start and end dates of discontinuous activities.
- Example: If a specific crew is required for a discontinuous activity, their availability should be planned around the activity's schedule, minimizing idle time during breaks.
- Pros: Enhances resource efficiency and reduces overall project costs.
- Cons: Requires accurate resource planning and communication with different teams.
1.5 Communication & Collaboration:
- Concept: Maintaining clear communication between all stakeholders involved in the discontinuous activity, including project managers, engineers, and contractors.
- Example: Regularly updating stakeholders on the activity's progress, anticipated breaks, and any potential disruptions.
- Pros: Promotes transparency and minimizes misunderstandings.
- Cons: Requires dedicated effort to ensure consistent communication and updates.
By combining these techniques, project managers can effectively manage discontinuous activities in oil & gas projects, mitigating risks and ensuring project success.
Chapter 2: Models for Discontinuous Activity Analysis
This chapter focuses on various models that can be used to analyze discontinuous activities in oil & gas projects, providing insights for efficient planning and risk management.
2.1 Critical Path Method (CPM):
- Concept: CPM analyzes the entire project schedule, identifying critical activities that impact the overall project duration. Discontinuous activities are factored into the calculation, allowing for accurate project timelines.
- Example: CPM can determine the impact of a delayed "Equipment Delivery" milestone on the critical path of a well drilling project.
- Pros: Helps identify critical activities and potential delays, facilitating effective resource allocation.
- Cons: Requires detailed understanding of activity dependencies and accurate duration estimates.
2.2 Monte Carlo Simulation:
- Concept: This probabilistic model simulates the project schedule multiple times, considering potential variations in activity durations, including those affected by discontinuous activities.
- Example: Simulating the well drilling project under different scenarios, accounting for potential delays in "Equipment Delivery" and "Weather Conditions".
- Pros: Provides insights into potential project completion ranges and identifies critical areas for risk mitigation.
- Cons: Requires significant data and statistical analysis expertise.
2.3 Network Diagram:
- Concept: Visual representation of the project schedule, depicting the dependencies between activities, including discontinuous activities.
- Example: A network diagram can illustrate the relationship between "Right-of-Way Clearing" and "Pipeline Laying", where the latter is a discontinuous activity dependent on the former.
- Pros: Provides a clear visual representation of the project's dependencies and allows for easy identification of potential bottlenecks.
- Cons: Can become complex for large projects with numerous activities.
2.4 Gantt Chart:
- Concept: A visual representation of the project schedule, highlighting start and end dates of each activity, including discontinuous activities.
- Example: A Gantt chart can display the planned start and end dates of a discontinuous "Well Completion" activity, taking into account the anticipated downtime for equipment maintenance.
- Pros: Offers a simple and intuitive overview of the project schedule.
- Cons: Lacks detailed information on activity dependencies and critical path analysis.
By utilizing these models, project managers can analyze the impact of discontinuous activities on the overall project schedule, identify potential risks, and develop effective mitigation strategies.
