Pipeline Maintenance

• Pipeline surveys, visual inspections and condition assessment
• Anti-corrosion protective coating system, as-per FROSIO and NACE codes
• Use of sphering and corrosion inhibitor injection into the pipelines

• Data collection and generation of Planned Preventative Maintenance guides
• Planned cleaning programme to prevent build-up of debris or deposits
• Use of Maintenance Management tools and software

• Decommissioning, recommissioning, purging
• Preparation of cleaning methodology
• Quality control and quality assurance
• Supply of cleaning tools and equipment
• Supply and installation of encirclement epoxy sleeves, repair clamps, shells and saddle tees (designed to fit pipelines ranging from 2″ – 48″)
• Bend and wrap repair for external wall metal loss, leak and corrosion defects
• In-service pipe welding and weld repairs
• Pressure testing, hydrostatic and acoustic
• Ultrasound testing and dye penetrant

• Replacement of damaged sections and/or defective valves
• Welding, flange management, epoxy coating

Emergency response in case of pipeline rupture, leakage, etc.

• Flushing of pipelines

Use of a broad range of pumps for flushing of pipelines (Selection of pumps (pressure and flow ranges) will depend on the scope of work)

• Cleaning of pipelines

Use of several kinds of pumps for cleaning of pipelines

Use several membrane pumps for inhibitor injection
(Chemicals can be used for removal of residue and/or rust)

• Inside pipeline coating

The internal pipeline coating process will reduce the friction with the pipe wall, so higher flows can be achieved with less energy, even pumping facilities can be designed with lower capacity

Also the resistance for corrosion internally will dramatically be improved

• Installation of cathodic protection, including anodes

This will help reducing the corrosion on the outside of the pipeline

• Foam Enerting

By injecting an inert foam, blown with nitrogen, we can plug a part of a pipeline without degassing the whole Pipeline, so works can be performed safely

• Taking back into service of pipelines

Either by using nitrogen, or by vaporising product (Ethane, Ethylene, Polypropylene etc.) until the line can be taken back into service again

• Flaring

Emptying of pipelines containing flammable liquids and or gasses by means of portable fully controllable flare systems

• Hot tapping & stoppling

Technique for pipeline modifications where the pipeline is not taken out of production

• Hot bolting

This technique allows for the replacement of one stud at a time until all the studs have been replaced on a. This allows for the preventative maintenance of corroding studs and nuts while the line is in service

The procedure enables personnel to quickly remove and replace studs and nuts when removal is preferred or necessitated by specific projects

• Bolt tensioning and bolt torquing

Hydraulic Bolt Tensioning is used to easily achieve an accurate and predetermined bolt loading in a single, simultaneous operation, providing the uniform gasket compression essential for the integrity of critically bolted connections such as pipeline flanges
