Main Objective
A method was developed to calculate stresses induced into a pipeline as the result of lowering it.
Public Abstract
A method was developed to calculate stresses induced into a pipeline as the result of lowering it. Simple computer programs were developed to calculate the following:
- Stress added as a result of lowering;
- Initial axial stress existing prior to lowering (requires lifting the pipeline and making certain measurements);
- Trench profiles which limit the added stress to a desired value;
- Temporary support spacing and allowable differences in support heights.
The safety issues associated with lowering a pipeline in service are discussed also. Recommended procedures for lowering are provided and the limtiations on lowering are discussed.
