Cleaning of obstructed/disconnected subsea Pipelines for decommissioning
We are seeking innovative solutions for the cleaning of subsea pipelines (rigid and flexibles) that are disconnected, have limited circulation (due to valve failures or obstructions), or face integrity limitations. In pipelines disconnected from the platform or subsea equipment, there is no possibility of direct fluid circulation or pigging from the platform for cleaning. In some cases, cleaning is performed by a rig that connects to the well, but this is a high-cost alternative that utilizes a critical resource. Water depths vary from 300m to 2000m.
Additionally, some pipelines have integrity issues that limit the pressure they can withstand, thereby affecting the quality of cleaning achieved through fluid circulation.
Key Points:
- Disconnected Pipelines: No direct fluid circulation possible.
- High-Cost Alternatives: Current methods, such as using a probe connected to the well, are expensive and resource-intensive.
- Integrity Limitations: Pipelines with integrity issues cannot withstand high pressures, limiting the effectiveness of fluid-based cleaning methods.
We look for Cost-effective, efficient, and safe solutions to clean (rigid and flexibles) and retrieve (flexible) subsea pipelines in such conditions within the scope of decommissioning projects.
