We build relationships with our customers, not contracts, and we believe that only through really understanding each other we can truly add value to each other’s business.
Personnel is our Strength Management and staff have a wealth of experience in upstream, midstream and downstream pipeline and process services all having worked for various service companies. They therefore contribute years of knowledge about job preparation, job execution, safety and quality.
At PNS, COIL and Slickline we fully understand above situation and have setup an extensive training program for Process, Pipeline and Well services. This training programme is for new employees who just joint this industry but also for our existing staff to strengthen their knowledge and expertise.
We rely on good staff. All our employees are dedicated, trained and retrained according to our Safety and Quality Management System.
It is not only theory practice in a classroom but real hands-on at our in-house test-loop facility. This test-loop is not only for internal use. We believe it is important that our business partners can fully understand and discuss problems and solutions with us on a high quality level. Therefore we also invite our customers and partners to register for a practical training course.
Besides executing a pre-job and post-job meeting after every job, regular brainstorm sessions are held with all personnel in order to find out where we can improve on preparation, safety, training, equipment, design and organizational performance. By doing this we are collecting all (operational) knowledge and experience and this is shared with all other operations within our company and obviously our clients. A structured way of collecting lessons learned, but also by the creation of a platform, where these lessons are learned (out of other jobs and/or other branches), this is shared with the operational staff. Our people are highly motivated and committed to respond quickly to customer requirements without compromising safety. The versatile staff is able to work in a wide range of disciplines. Demonstrating why our company group is the best choice in selecting a service provider.
Recruitment and Training Organizations in the Oil and Gas sector are realigning on good people in the field to meet their core business objectives. Itâ€™s a truism that the best asset that most organizations have are their people.
PNS - Process Industry Services The processing industry demands specialized nitrogen services in order to optimize plant and pipe operations, reduce shutdown times and save costs. PNS is providing a broad range of services that ensure a high operation quality during the whole life cycle of a process plant. Integrated precommissioning Services Prior to the start-up of any new process plant or module there are certain requirements that must be met before hydrocarbons or product can be introduced safely. PNS provides procedures and risk assessments based on industry knowledge and experience for each service offered. Nitrogen purging, drying & product displacement The hydrocarbon processing industry deals with many hazardous products which need to be removed from the facilities before any maintenance or cleaning work can be executed. Nitrogen / Helium leak testing Experience proves that LEAKS do occur, mostly during plant start-up, after commissioning of new facilities or after the execution of maintenance on existing facilities. Enhanced nitrogen reactor cooldown The use of catalysts has increased as the quality of crude has decreased. This increasing use of catalysts has focused more attention on catalyst turnaround and handling and the time associated with these activities. Enhanced nitrogen reactor cooldowns are executed to speed up the reactor cooldown process. They minimise downtime, lower cost over conventional methods and increase safety and controlled operation
Nitrogen pumping & vaporisation Nitrogen Pumping is used in numerous applications to solve many industrial problems. PNS pump units are of the latest design and manufacture and have the versatility to meet various pressure, flow and temperature requirements. PNS vaporisation unit types include N2 HP pump unit, steam vaporiser and ambient vaporiser Hydrostatic & pneumatic testing Hydrostatic testing of pipelines and vessels is performed to expose defective materials that have missed prior detection, ensure that any remaining defects are insignificant enough to allow operation at design pressures, expose possible leaks and serve as a final validation of the integrity of the constructed system. For pneumatic test PNS use compressed air or nitrogen as a media, in case of hydrostatic testing we use either water or clientâ€™s product as media.
PNS - Pipeline Industry Services Maintenance, support and inspection are becoming more and more important to extend the life cycle of the pipelines. Pipelines always involve work to be executed under the most difficult circumstances due to the lay out, location, age, and variations and non-pig ability. It is vital that pipelines are tested upon strength, are leak tight and cleaned and inspected regularly to secure the pipeline integrity. PNS has a complete pipeline service program from commissioning maintenance and decommissioning package to safeguard safe and smooth pipeline operation during the whole life cycle of this valuable asset. Pipeline (pre) commissioning
Pipeline product and gas filtering
PNS has all the services, equipment and experiences to carry out a complete Pre-commissioning program of; Pipeline cleaning, gauging, filling (flooding) and Hydrostatic testing
During online pipeline pigging or process cleaning dust and debris can get lose but needed to be separated from the rest of the installation. PNS has a professional designed mobile twin filter unit for online pipeline pigging operations.
Pipeline mechanical and chemical cleaning Pipeline hydrostatic and strength testing It is important to clean the line from debris or condensate what can affect other installations. We have years of experience in pipeline cleaning, mechanical and with chemical solutions, with the right designed PIG for it purpose.
PNS has many years of experiences in hydrostatic testing from small to large diameter long lines, for Onshore and Offshore clients. Together with our cleaning and pigging services we can combine into a complete service package for our clients,
Pipeline geometry and location (xyz) surveys Pipeline air or nitrogen drying The tool for pipeline geometry or pig survey is purpose built to measure any deformations in the pipeline, which could cause deformation and coating loss resulting into corrosion. Also the pipeline pig ability needs to be maintained for Inline Inspection programs.
Pipeline drying follows upon hydrostatic testing, dewatering and the run. Injection of super dry air at a dew point of much lower than 40˚C shall be continued up to the moment that the target dew-point is reached; In case lower dew points of - 65˚C.have to be achieved PNS offers nitrogen drying.
Pipeline inspection services (with ILI suppliers)
PNS can offer a complete inspection program from Traps, spools, pumps, tanks, cleaning programs and ILI inspection with one of our selected ILI suppliers.
To provide a temporary isolation of pipeline sections PNS provides the “direct freeze method”. The freeze plug is generated by filling a purpose built temporary jacket with liquid nitrogen. The system is ideally applicable on stainless steel and carbon steel pipelines.
Pipeline decommissioning and abandonment
Pipeline & tank leak testing (above and underground)
The first step in abandonment of a pipeline is decommissioning. With our offshore experience and equipment PNS is able to engineer, setup and execute a decommissioning program for every individual project.
The portability and light weight of the PNS Heli-test equipment (Varian PHD-4) plays a major role in this application. Underground pipelines and storage tanks are pressurized with helium which can escape through small leaks and migrate to the surface. There it can be easily detected by the PHD-4.
PNS - LNG Industry Services PNS has an experienced team of specialists who have successfully engineered the commissioning and cool-down on some of the largest LNG installations across Europe. Our early involvement through construction and into start-up has enabled us to tailor our service offerings to improve safety, efficiency and quality during the complete project.
PNS engineers have assisted with design reviews of LNG terminals in order to assess the constructability, testing philosophy and future maintenance requirements. A good up front understanding of the project requirements is the first step to achieving a clean start up.
The most critical time of any oil & gas project is the start-up phase, even more so on an LNG terminal as the first cargo can be waiting to be unloaded. Using our cool down systems which are designed to supply only cold Nitrogen gas, PNS is able to reduce the wall temperature of the terminal unloading header to temperatures down to -140˚C in a short period of time. This can allow the first cargo to be discharged straight into the unloading system with less concern worry of pipe work movement due to temperature difference across the pipe wall.
Construction One of the most important activities during the construction phase is the pneumatic pressure testing. Tried and tested procedures and safety systems ensure that every precaution is in place prior to these operations. It is essential to work towards the start-up of the facility from day one. Systems can have all critical joints torque/tensioned and tagged, be camera inspected, pressure tested, high velocity blown and even dried to a certain extent. This can drastically reduce pre-commissioning time.
Pre-Commissioning Prior to the start-up of any LNG terminal certain requirements must be met, these can include: All Critical joints correctly assembled and tightened, all spades and spacers in the correct position, all cryogenic systems dried (-60˚C Dewpoint), all Non-cryogenic gas systems dried (-25˚C Dewpoint), all Hydrocarbon systems leak tested, all Hydrocarbon systems Oxygen free (Less than 2%).
LNG Tanks PNS have had great success with LNG tank testing and commissioning. We carry out hydro testing using our Hydro cyclone which filters the testing water to ensure minimum residue is left behind. For the pneumatic testing we supply clean, dry and oil free air at high flow rates, it is often beneficial to carry out the tank drying at this stage. The final stage is the oxygen freeing, PNS has a large selection of Nitrogen supply equipment to achieve this in the shortest possible timescale. During all activities PNS ensures accurate measurement and record keeping by supplying monitoring and data logging facilities.
PNS - Boltworking & Onsite Machining Services The principle of a bolted joint is based on the induced bolt load delivering sufficient joint compression and gasket seating stress to withstand maximum service pressure and forces. This is when the bolting is under tensile load. A minimum level of operational gasket seating stress must be maintained throughout joint service, therefore the design bolt load/compression target on installation should allow for creep, relaxation, uncertainty over service loadings and the tolerances of components and tools used. This load can be applied by various different methods but there are certain constants that must always be in place to ensure a leak free joint. All of our Bolting Technicians have full ECITB accreditation, CCNSG (Contractor Safety Passport), OPITO UK Offshore Survival & Medicals.
Torque Tightening (Hand & Hydraulic) The accurate tightening of awkward and straightforward flanges alike and requires no specialist bolting (e.g. longer studs as required with Tensioning).
Hydraulic Bolt Tensioning With this method of tightening the load is applied direct through axial extension of the bolts. Bolt Tensioning is often specified as being the preferred method of tightening throughout the Oil & Gas Industry for all fasteners of 1 1/8”Ø and above.
Flange Spreading Enable our clients to gain quick and safe access to flange faces to assess their condition and clean prior to assembly and subsequent retightening.
Nut Splitting A full range of Nut splitters enable the fast/safe and controlled removal of seized fasteners.
Ultra-Sonic Bolt Measurement Enable our clients to achieve “Fully Controlled Tightening” of threaded fasteners. This method is especially popular on safety critical (Reactor Tops etc.) and problematic bolted connections.
Joint Integrity / Flange Management We have a proven track record in our management of Joint Integrity Services on major construction projects in Europe and abroad. The management of these projects can range from individual Joint Completion Certificates, to a simple Flange Break and all the way through to “Asset Integrity Management Software”.
Onsite Machining Services At PNS we have the capability to provide our clients with a multitude of machining services ranging from a simple pipe cut to Heat Exchanger Tube repairs. Performing the machining activities on-site reduces “Asset Downtime”, the need for costly removal and shipping of pipework/equipment is reduced. Our capabilities include
