Spool Piece Metrology using LIDAR (LiDAR Metrology)
Using subsea LiDAR for spool piece metrology – LiDAR Metrology – has been proven to significantly improve operational efficiency, reduce costs and enable operators to reach first oil faster. LiDAR Metrology also offers a significant by product in the form of high resolution 3D datasets of existing assets which can be leveraged in life of field and asset integrity applications.
The value of LiDAR Metrology includes:
- Reducing the need for special tooling or docking receptacles on the structures
- Reducing the need for rigging equipment
- Reducing surface crane operations
- Reducing the risk profile by not “touching” the assets
- Reducing the time required to perform the data collection and processing
- Improving life of field and integrity management with the development of accurate 3D surveys of the field
Spool pieces (or jumpers in deep water fields) represent one of the final components of a production hydrocarbon network and one of the final steps to “first oil” for producers. The spool pieces connect subsea assets and can have a variety of configurations based on the field layout, water depths and other environmental and engineering factors. Spool piece lengths range from relatively short rigid spools of 5-10m, flexible jumpers that are 20-30m and horizontal spool pieces that lay on the seabed and can exceed to 90m in length.
