Hammock Exercise

Scenario: You are the project manager for a new oil well construction project. The project involves several key activities:

• Site Preparation: Clearing the site, building access roads, etc.
• Drilling: Drilling the well to the target depth.
• Well Completion: Installing casing, cementing, and testing the well.
• Pipeline Construction: Building a pipeline to connect the well to the processing facility.

Task: Create a hammock structure for this project. Identify the overarching hammocks you would use to manage the project and explain why you chose these specific hammocks.

Hammock in Oil & Gas Project Management: A Detailed Exploration

This document expands on the concept of "hammocks" in oil and gas project management, providing detailed information across various aspects.

Chapter 1: Techniques for Implementing Hammocks

The effective implementation of hammocks requires careful planning and execution. Several key techniques ensure their successful integration into project management workflows:

• Work Breakdown Structure (WBS) Decomposition: The foundation for hammock implementation is a well-defined WBS. Activities should be grouped logically into higher-level summaries (hammocks) based on functional similarity, dependencies, or management needs. This ensures that hammocks represent meaningful aggregations of work.

• Defining Dependencies: Clearly defining dependencies between hammocks and individual tasks within them is crucial. This facilitates accurate scheduling and progress tracking. Techniques like Precedence Diagramming Method (PDM) or Activity-on-Node (AON) networks can be used to visualize these relationships.

• Resource Allocation Strategies: Resources (personnel, equipment, materials) should be allocated to hammocks considering their overall scope and dependencies. This requires a holistic view of resource requirements across multiple lower-level tasks. Resource leveling techniques can optimize resource allocation to avoid bottlenecks.

• Progress Tracking and Reporting: Develop a system to track the progress of both individual tasks and the overarching hammocks. This may involve using Earned Value Management (EVM) principles to measure performance against planned schedules and budgets. Regular reporting at both detailed and summary levels (hammock level) is essential.

• Risk Management Integration: Identify and assess potential risks associated with each hammock. This higher-level risk assessment complements the detailed risk analysis performed on individual tasks. Risk mitigation strategies should address potential impacts at the hammock level.

• Change Management: Establish clear procedures for managing changes to the project scope that affect hammocks. Changes should be carefully analyzed to understand their ripple effects on related tasks and other hammocks.

Chapter 2: Models for Hammock Representation

Various models and diagrams can effectively represent hammocks within a project:

• Hierarchical Task Networks: These graphical representations show the hierarchical breakdown of the project, clearly depicting hammocks as higher-level summaries encompassing multiple sub-tasks.

• Gantt Charts: Gantt charts can visually represent hammocks as summary bars, providing a high-level overview of the project schedule. The progress of individual tasks within a hammock can be represented by progress bars within the summary bar.

• Network Diagrams (PDM/AON): These diagrams explicitly show the dependencies between hammocks and individual tasks, facilitating critical path analysis and schedule optimization. Hammocks appear as high-level nodes connected to their constituent sub-tasks.

• Earned Value Management (EVM) Systems: EVM systems utilize a work breakdown structure naturally accommodating hammocks. Progress, costs, and schedule variances can be tracked and reported at both the individual task and hammock levels.

Chapter 3: Software Tools for Hammock Management

Several software applications support hammock management:

• Project Management Software: Most comprehensive project management software (e.g., Microsoft Project, Primavera P6, MS Project Online) allow for the creation of hierarchical task structures, facilitating the definition and management of hammocks.

• Custom Databases: Organizations may develop custom databases to manage projects, tailored to their specific needs and incorporating hammocks as a key element of their reporting structure.

• Spreadsheet Software: While less sophisticated, spreadsheets (e.g., Microsoft Excel, Google Sheets) can be used for simpler projects to track hammock progress and reporting. However, complex projects benefit significantly from dedicated project management software.

Chapter 4: Best Practices for Hammock Implementation

Successful implementation of hammocks hinges on these best practices:

• Clear Definition: Ensure hammocks are clearly defined, with well-defined boundaries and measurable objectives. Ambiguity can lead to confusion and inaccurate reporting.

• Appropriate Level of Detail: Find the right balance between detail and summarization. Overly broad hammocks obscure individual task progress, while overly granular hammocks defeat the purpose of summarization.

• Regular Review and Update: Regularly review and update the hammock structure to reflect project changes and maintain accuracy.

• Communication and Collaboration: Effective communication among project team members is essential. Regular status meetings and updates keep everyone informed about hammock progress.

• Training and Education: Proper training on hammock techniques ensures that all stakeholders understand and correctly use the system.

Chapter 5: Case Studies of Hammock Application in Oil & Gas

Several successful applications of hammocks in oil and gas projects are observed:

• Offshore Platform Construction: A "Platform Installation" hammock could encompass subsea pipeline installation, topside construction, and commissioning.

• Pipeline Project Management: A "Pipeline Construction" hammock might include right-of-way acquisition, pipeline laying, and testing.

• Oilfield Development: A "Well Completion" hammock may include drilling, cementing, stimulation, and testing.

• LNG Plant Construction: A "Process Unit Construction" hammock could cover the construction of individual process units within a larger LNG plant. These case studies demonstrate how hammocks improve project visibility, facilitate better resource allocation, and streamline reporting for complex projects. The success of these applications is often tied to the careful selection of appropriate tasks to be grouped under a single hammock, the establishment of clear dependencies between hammocks, and the consistent use of effective progress tracking and reporting tools.
