Techniques

Chapter 1: Techniques of Finish to Start Relationships in PDM

This chapter delves into the intricacies of defining and utilizing Finish to Start (FS) relationships in PDM software, specifically focusing on its application in oil & gas projects.

1.1 Defining the FS Relationship:

• Predecessor and Successor Activities: FS relationships establish a clear linkage between two activities: the predecessor activity, whose completion triggers the commencement of the successor activity.
• Lag Time: While the default FS relationship assumes immediate start upon completion, PDM allows for defining lag time, a buffer period between the predecessor's finish and the successor's start. This can be used to account for delays caused by resource availability, approvals, or other factors.
• Types of Lag: PDM offers different types of lag, such as Start-to-Start (SS), Finish-to-Finish (FF), and Start-to-Finish (SF), which can be combined with FS to achieve more nuanced scheduling.

1.2 Application in Oil & Gas Projects:

• Construction and Installation: FS relationships are crucial for activities like pipeline welding and inspection, where subsequent segments can only be installed after the completion of preceding sections.
• Drilling and Completion: FS ensures that drilling activities can only commence after wellhead preparation is finalized.
• Production and Processing: Processing plants are only operational after the completion of extraction and transportation of oil & gas resources.
• Maintenance and Repair: Repairing equipment, like valves or pipelines, can only start after the completion of necessary shutdown and safety protocols.

1.3 Advanced Techniques:

• Conditional FS Relationships: PDM allows for defining FS relationships based on specific conditions. For example, an activity might only start after a certain milestone is reached or if specific equipment is available.
• Multiple FS Relationships: Activities can have multiple FS relationships, meaning they depend on the completion of several preceding activities. This is especially useful for complex tasks with multiple dependencies.

1.4 Challenges and Considerations:

• Over-constraining the Schedule: Excessive FS relationships can create a rigid schedule, hindering flexibility and adaptability.
• Resource Availability: Defining FS relationships should take into account resource availability and potential resource conflicts.
• Data Accuracy: The effectiveness of FS relationships depends heavily on the accuracy of activity durations and dependencies.

Chapter 2: Models for Effective FS Relationship Implementation

This chapter explores various models and strategies for effectively integrating FS relationships into oil & gas project schedules.

2.1 Critical Path Method (CPM):

• Identifying Critical Activities: CPM uses FS relationships to identify the critical path, the sequence of activities with the longest duration.
• Focusing on Critical Activities: By focusing on the critical path, project managers can prioritize efforts and resources to ensure timely completion of the project.
• Float Analysis: CPM allows for calculating float, the amount of time that activities can be delayed without impacting the overall project schedule. This provides valuable insight into potential delays and slack.

2.2 Network Diagram Method:

• Visual Representation: Network diagrams, like Activity on Arrow (AOA) and Activity on Node (AON), visually represent activities and their dependencies using arrows or nodes.
• Understanding Interdependencies: Network diagrams facilitate a clear understanding of the relationships between activities and highlight potential bottlenecks.
• Sensitivity Analysis: These diagrams help analyze the impact of delays in specific activities on the overall project schedule.

2.3 Monte Carlo Simulation:

• Uncertainty Analysis: Monte Carlo simulation uses random variables to simulate the impact of uncertainties in activity durations and dependencies on the overall project schedule.
• Risk Assessment: This method assists in assessing the likelihood and impact of delays and helps identify areas where contingency planning is crucial.

2.4 Resource-Leveling Techniques:

• Resource Constraints: PDM incorporates resource-leveling techniques to manage resource availability and ensure efficient resource allocation.
• Balancing Workload: These techniques balance the workload of resources and optimize the schedule while considering resource limitations.

2.5 Project Management Software Integration:

• PDM as a Tool: PDM software is essential for defining and managing FS relationships. It provides tools for creating, analyzing, and updating schedules based on defined dependencies.
• Collaboration and Reporting: PDM platforms facilitate team collaboration, communication, and reporting, allowing for real-time updates and monitoring of progress.
