Portable Offshore Accommodation Modules (PAMs) are essential in supporting offshore oil and gas exploration and production. These modules are deployed on various vessels, ranging from shallow-water drill barges to deep-water drill ships. Over the years, PAMs have evolved from simple refitted cargo containers into advanced, fully integrated personnel spaces capable of supporting operations in some of the world’s harshest and most remote environments.
In the past decade, there has been a significant increase in demand for PAMs. This demand is driven by the need for new technologies, safe and comfortable accommodations for growing numbers of offshore personnel, and flexible solutions that can be integrated across multiple vessel platforms.
The rise of offshore wind development and scientific research has further expanded the use of PAMs, particularly on Offshore Supply Vessels. Offshore wind operators are now outfitting these vessels with 12-16 PAM units, designed to house hundreds of workers for weeks at a time, effectively creating floating hotels. Scientific research has also led to the design of highly sophisticated PAMs that house control systems for Remote Operated Vehicles (ROVs), Unmanned Surface Vehicles (USVs), and Unmanned Aerial Vehicles (UAVs), as well as secure office spaces for analysts and engineers.
In 2015, the United States Coast Guard (USCG) recognized the need for standardized designs and procedures for Portable Accommodation Modules used on inspected vessels and facilities. The resulting USCG Policy No. 01-16 outlines the requirements for the design, planning, installation, inspection, and documentation of PAMs. This policy has significantly streamlined the process, although it has also increased the planning and installation costs associated with PAMs.
Key Lessons from Installing PAMs on Offshore Vessels
My experience with PAMs has primarily involved installing accommodation and office space modules on ABS Alternate Compliance and USCG-inspected vessels. Over the years, I’ve learned several valuable lessons that have contributed to the successful integration of PAMs:
- Pre-planning and Communication: Successful installation begins with thorough planning and clear communication with the charter client. These two factors are crucial for a smooth installation process.
- Engineering Requirements: The engineering requirements set by ABS and the USCG are stringent. While hiring an experienced naval architect may incur higher upfront costs, it ensures that the submitted plans are approved on time, preventing costly delays.
- Manufacturer Support: Working with experienced PAM manufacturers like HB Rentals offers the benefit of technical representatives who specialize in integrating PAMs with vessel fire detection and general alarm systems. These representatives are also invaluable for troubleshooting any issues that may arise.
- Know Your Inspectors: Different Offices of Commercial and Marine Inspection (OCMI) or ABS offices may focus on different areas during commissioning inspections. It’s crucial to be prepared for any and all questions and always have the Portable Accommodation Module Record Book available for reference.
Looking Ahead: The Future of Portable Accommodation Modules
The use of PAMs is poised to grow and evolve as offshore projects become more complex. Whether for oil and gas exploration, offshore wind development, or scientific research, partnering with an experienced vessel operator or charterer is essential to ensure the on-time delivery and success of any mission involving PAMs.
