To calculate pup-piece length for a 12 inch pipeline with two sections already lowered and overlap 5m and s-bend rolling, two 90 degree LR bends.

• Calculate the total length of the pipeline

• Subtract the length of the two sections already lowered and overlap 5m

• Add the length of the two 90 degree LR bends

• Divide the result by 2 to get the length of each pup-piece

Collapse and damage percentage for HDD crossings are calculated based on various factors such as soil type, borehole diameter, and drilling fluid properties.

• Collapse percentage is calculated using the Mohr-Coulomb failure criterion

• Damage percentage is calculated based on the tensile strength of the pipe and the bending stress induced during the pullback process

• Factors such as soil type, borehole diameter, and drilling fluid properties also play a role in determining collapse ...read more

The gap between two pipelines refers to the distance or separation between them.

• The gap between two pipelines is typically determined by safety regulations and engineering standards.

• The gap is important to prevent interference between pipelines and ensure proper maintenance access.

• For example, in offshore pipelines, the gap between them is usually around 20-30 meters to allow for safe operations.

Back filling is the process of refilling an excavated area with soil or other materials to restore the ground to its original level.

• Back filling is done after the installation of pipelines to cover and protect them.

• The process involves carefully placing and compacting the backfill material to prevent settling or damage to the pipeline.

• Common backfill materials include sand, gravel, and crushed stone.

• Back filling is an important step in the construction of pipelines to ensure ...read more

The process before laying a pipeline involves planning, surveying, obtaining permits, clearing the right of way, and preparing the trench.

• Planning the route of the pipeline to ensure efficiency and safety

• Surveying the land to identify any obstacles or potential issues

• Obtaining necessary permits and approvals from relevant authorities

• Clearing the right of way by removing any vegetation or structures in the path

• Preparing the trench where the pipeline will be laid, including exc...read more

Pipe laying is the process of installing pipes underground or underwater for various purposes such as transportation of fluids or gases.

• Pipe laying involves digging trenches or using specialized equipment to lay pipes in the ground.

• Pipes can also be laid underwater using techniques such as horizontal directional drilling or pipe jacking.

• The pipes are then connected together and tested for leaks before being put into service.

• Examples of pipe laying projects include oil and gas...read more
