With the unseasonably wet weather the UK has experienced this year, here we remind landowners “Don’t dig near to pipelines” without permission from the pipeline operator.

Britain has more than 27,000 km of buried pipelines used to transport a range of products at high pressures of up to 100 bar. This includes flammable and explosive products such as oil, natural gas, ethylene, and petroleum, as well as less obviously hazardous materials such as water.

Prior to working in the vicinity of high-pressure pipelines, landowners are required to contact the pipeline operator. BPA asks its landowners that they are notified for any works within 50m of a pipeline, particularly if the pipeline is known to be at a shallow depth.

When we are contacted we can provide safety guidance and advice including coming out and marking out the pipeline to enable the farmer or landowner to carry on with the required activities.

Contractors, employees and temporary staff working on the land also need to be informed of the pipeline locations to discuss and agree on the necessary precautions before starting work.

Agricultural activities that pose a significant risk to pipelines include the installation or repair of drainage pipes or clearing ditches near buried pipelines. Such activities often require heavy machinery and can easily excavate close to the pipeline’s nominal depth of 1m.

To prevent risks to landowner and pipeline, anyone planning works within 3 metres of a our buried pipelines must obtain permission from BPA. This is not to prevent the works, but simply to ensure they are undertaken safely.

Pipeline marker posts

The locations of pipelines are normally indicated by marker posts at the edges of fields; however, marker posts can be accidentally moved or damaged, and pipelines may not run in a straight line between posts and aerial markers.

Who to contact for buried pipelines

Pipeline marker post

The depth of the pipeline’s cover may also be reduced in parts, so contact our lands team so we can advise on the exact location of the pipeline. We can arrange to visit the site, trace and accurately mark out the exact pipeline location, and provide guidance on safe working while near to the pipeline.

To help ensure the best and safest outcomes for all, farmers or contractors are advised not to undertake any works within three metres of a buried pipeline. If planning works, please:

  • Never assume the route or depth of pipeline.
  • Give pipeline operators sufficient notice before works begin.
  • Do not proceed with works until consent is given by the pipeline operator.
  • Be aware that pipeline depths vary and can often be found less than 1m below the surface.
  • Remember pipelines do not always run in straight lines between marker posts.
  • Be aware that other safety-critical infrastructure, such as cables, valve chambers and standpipes, can be buried along the pipeline lengths; these can be found at even shallower depths than the pipeline.

Landowner Responsibilities

Damage to pipelines can pose a significant risk to life, as well as potentially serious environmental damage if a product is released. It can also lead to prosecution by the HSE as Regulation 15 of the Pipelines Safety Regulations Act states: “No person shall cause such damage to a pipeline as may give rise to dangers to persons”.

Working near pipelines without taking the correct precautions can have serious consequences and potential prosecution.  It is the landowner’s responsibility to ensure that employees, contractors and others operating on their land comply with regulations.

As well as potential prosecution, damage to the pipeline could lead to environmental harm through serious pollution of soil, water, and the atmosphere, which is likely to lead to prosecution by the Environment Agency. The cost of repair and subsequent clean-up is likely to exceed £1m.

If in doubt, contact BPA as we are here to help. More information and videos on what to do and not do near to buried pipelines can be found here.

CIPS Survey clearance

BPA’s lands team is undertaking a programme of scrub clearance works at more than 60 sites along the route of the buried high-pressure oil pipelines that BPA manages in the UK.

The scrub clearance is in preparation for a new CIPs survey which is scheduled to start in October and run until the end of November 2020.   The work will take place on the LAP pipeline that feeds Heathrow Airport, the buried pipeline that runs between the Thames Pump Station and the Epping Pump Station and also the buried high-pressure oil pipeline that runs between the Blisworth Pump Station and the Oil Storage Terminal at Kingsbury.

A CIPS survey is sometimes referred to as Close Interval Survey, which is an above ground, non-intrusive survey, used to accurately determine the effectiveness of the cathodic protection system along the pipelines.  The survey helps ensure that the integrity of the pipeline remains protected from corrosion.

The pipe-to-soil readings are measured at test points typically installed at 1 to 2 kilometre intervals along the pipeline route, however these measurements do not accurately reflect the pipe-to-soil potentials between test points.

To overcome this, a close interval potential survey (CIPS) is undertaken, with pipe-to-soil potentials measured at nominal 2 metre intervals. The CIPS technique can be employed for both buried (onshore) and immersed (offshore) pipelines.

To allow BPA’s Lands team access to points on the ground above the buried pipelines a programme of scrub clearance is being undertaken at points where readings will be taken.  BPA will write to all affected landowners and tenants ahead of the survey. If you have any special access arrangements or any that may have changed please let us know.

The team at BPA will be wearing high-vis clothing and following all the correct procedures required for working near to buried pipelines.

Keep a watch out for the team and don’t forget to contact the BPA Lands Team if you see anything suspicious or any unusual activity along the buried pipeline network.  If in doubt, simply call us on 0800 585 387 and we will do the rest.

 

Pipe-Burying

The team at BPA is currently undertaking a programme of burying above ground pipelines as they are unsightly and potentially dangerous.  the team will be working in the Hertfordshire and Staffordshire area over the summer.
