Techniques

Chapter 1: Techniques for Defining and Managing Controlling Relationships

This chapter delves into the practical techniques used to define, manage, and analyze controlling relationships within oil & gas project scheduling. The core of effective scheduling lies in accurately representing these dependencies.

1.1 Precedence Diagramming Method (PDM): PDM, a widely used technique, visually represents the relationships between activities using a network diagram. Arrows indicate the direction of the dependency, while nodes represent individual activities. Different arrow types (e.g., solid, dashed) or annotations explicitly define the type of controlling relationship (FS, SS, FF, SF). This allows for a clear visualization of the project's logical flow and identification of critical paths.

1.2 Activity-on-Node (AON) vs. Activity-on-Arrow (AOA): The choice between AON and AOA diagrams impacts how controlling relationships are represented. AON, where activities are represented by nodes, is generally preferred for its clarity and ease of understanding, particularly in complex projects.

1.3 Defining Relationship Types: The chapter emphasizes the practical application of the four primary relationship types (FS, SS, FF, SF):

• Finish-to-Start (FS): This is the most common and often default relationship. Clear examples relevant to oil & gas (e.g., pipeline installation must finish before testing can begin) highlight its importance.
• Start-to-Start (SS): Explaining scenarios where simultaneous activities are necessary, such as parallel construction phases or concurrent environmental impact assessments.
• Finish-to-Finish (FF): Illustrating scenarios where the completion of one activity is tied to the completion of another, such as finishing a wellhead installation before finishing the well completion process.
• Start-to-Finish (SF): Less common but crucial in specific situations, such as decommissioning activities where the start of one task depends on the finish of a predecessor.

1.4 Techniques for Identifying Relationships: This section explores methods for identifying controlling relationships, including:

• Workshops and Brainstorming Sessions: Facilitated sessions involving stakeholders to collectively define dependencies.
• Reviewing Engineering Documents: Extracting dependencies from detailed engineering drawings, specifications, and procedures.
• Using Checklists and Templates: Standardized forms to ensure consistent and comprehensive capture of relationships.
• Software-Assisted Analysis: Leveraging scheduling software capabilities to analyze dependencies.

1.5 Managing Changes to Relationships: The dynamic nature of oil & gas projects requires a robust approach to managing changes in relationships. This section covers techniques such as:

• Change Management Processes: Formal procedures for documenting, evaluating, and approving changes to the schedule.
• Impact Analysis: Assessing the effect of changes to relationships on the project schedule, critical path, and resource allocation.
• Version Control: Maintaining a history of changes to relationships for auditing and traceability.

Chapter 2: Models for Representing Controlling Relationships

This chapter explores different scheduling models and their ability to represent and manage controlling relationships.

2.1 Network Diagrams: A detailed explanation of how different types of network diagrams (PDM, AON, AOA) represent the four relationship types, highlighting their advantages and disadvantages in the context of oil & gas projects.

2.2 Gantt Charts: While not explicitly showing the relationship types as clearly as network diagrams, this section explains how Gantt charts incorporate controlling relationships through task dependencies and scheduling constraints. Focus is placed on interpreting the implications of these dependencies within the visual representation.

2.3 Critical Path Method (CPM): A comprehensive explanation of how CPM utilizes controlling relationships to identify the critical path, which is crucial for resource allocation and risk management in oil & gas projects. The concepts of forward and backward pass calculations are explained.

2.4 Program Evaluation and Review Technique (PERT): This section compares and contrasts CPM and PERT, focusing on how both methods handle uncertainties and incorporate probabilistic estimations into the project schedule, impacting the interpretation and management of controlling relationships.

2.5 Resource-Constrained Scheduling: This section focuses on models that incorporate resource limitations when scheduling projects. It explains how resource constraints can modify and limit the flexibility allowed by controlling relationships. Methods like resource leveling and resource smoothing are discussed.

Chapter 3: Software for Managing Controlling Relationships

This chapter examines various software tools that facilitate the creation, management, and analysis of controlling relationships within oil & gas project scheduling.
