Rig Lay-Up & Preservation Services

Rig lay-up and preservation services are tailored to our clients’ requirements to prevent excessive or accelerated deterioration of the rig and its equipment. These preservation procedures will greatly depend on a company’s needs to either warm stack or cold stack their assets.

  • Pre-Stacking Survey for preservation stacking planning
  • Warm Stacking (contract ready)
  • Cold Stacking (dead vessel)
  • Preservative Measures
  • Maintenance
  • Re-commissioning and Reactivation
  • Stacking Management and Re-commissioning Software

The objectives of the OCS asset preservation program are twofold and are noted in no priority, one to minimize the company’s exposure financially while new revenue streams are being sourced. While at the same time protecting the assets ensuring the equipment’s full term “life cycle” can still be realized, and as a consequence the unit and assets returned to service economically in the shortest possible period of time. Our competitors are focused in the main on preservation only; our first hand operational experience uniquely aligns us with our clients’ requirements.

Decisions to either warm or cold stack an asset could vary greatly on a client’s business plans but generally assets tend to be warm stacked if potential work is seen in the next 12 months, or clients that have special considerations for instance smaller companies or specialised companies focused on newer assets.

Where it’s seen that no foreseeable work is likely over the next 12 months clients are more tending to cold stack their assets, older assets may even be taken out of service permanently due to the high costs of reactivation.

Our stacking services comprise general advisory on lay-up scenarios by way of detailed inspections, the development and implementation of lay-up specifications and procedures. The supervision of the lay-up process, periodic maintenance and re-commissioning, are all supported by our unique Preservation-Trac & Project Trac software that allows our clients to view in real time all activities during the whole layup process through to the units planned re-commissioning.

All inspections, lay up and preservation routines in either scenario will specifically recommended practices to API, IMO, SOLAS, MODU Codes, ABS and DNV Rules.

As the result of requests from our client’s over the last 12-months OCS has developed comprehensive packages providing our clients with preservation solutions that are tailored to their particular requirements. OCS as a complete service provider focusing on the re-activation during the preservation process.

Why do you need OCS?

OCS is recognized as one of the most respected and accomplished global companies in the industry, with close to 20 years of experience specialising in Project Management, Rig Commissioning, Rig Inspections, Hazardous Area Equipment Inspections & Management, Electrical Installation, Maintenance. In addition, OCS one of the most modern, state-of-the-art technical training facilities in the industry located in Houston.

When combined with our exhaustive planning and software package (Project Stack), OCS delivers the complete package.

While stacking is a huge task, it is a relatively simple process. However, one of the biggest challenges for clients is the reactivation process. This is where OCS excels, with well over 100 projects in rig commissioning and multiple reactivations.

OCS stacking solution has an enormous advantage with our commissioning and project management software, which has been optimized to include preservation procedures and tracking management of the stacking process. When reactivation occurs, a full reactivation and commissioning package is ready with all mechanical completions included and commissioning procedures only needing to be tailored to suit the asset as all equipment is accounted for. This process can save your company a tremendous amount of time in the reactivation planning and the exhaustive process of re-commissioning all equipment.
