WELDING SERVICES Proserv offers qualified welders and welding procedures for structural, pressure containing and friction stud applications to most codes or standards.  Proserv also offers customer inspection services to evaluate the integrity of material, components or systems without causing damage through Non-destructive examination (NDE) or Non-destructive Testing (NDT).

Structural and Pressure Containing Proserv technicians are trained and equipped for welding processes SMAW (Stick), GMAW(MIG), FCAW, GTAW(TIG) and Orbital GTAW applications for new fabrication, maintenance and weld repair involving a range of materials including 4130, structural steels, stainless steels, and duplex stainless steels. MIG and TIG welding processes grant our highly skilled operators greater control for stronger, more consistent welds. Qualified welders and procedures offer clients high quality welding onshore and offshore at any global location. NDE/NDT Inspection Services Proserv has qualified NDE personnel, certified in accordance with ASNT SNT-TC-1A standards that can inspect weld integrity to our customer’s Inspection Test Plans (ITP). Proserv technicians perform a Liquid Penetrant Inspection that utilizes noticeable red dyes under detectable light conditions to reveal surface flaws, on parts and equipment with almost any material, which might not otherwise be visible. The test identifies welding surface defects such as hairline cracks, surface porosity and fatigue cracks on in-service components. Friction Stud Welding Proserv’s portable Friction Stud welding systems are used for special applications such as welding underwater and welding safely topside in explosive environments. The HMS 3000 Friction Welding System is hydraulically powered and controlled via laptop and primarily used for subsea applications such as attachment of anodes on subsea structures, assets, live pipelines and FPSOs. The R1004 Friction Welding System is pneumatically powered and able to perform welds in a Zone 2 area for topside applications such as attachment of equipment to an offshore platform deck area with M12 studs using a fitted shroud system.


FLUSHING SERVICES Proserv offers trained field technicians to perform a variety of filtration and flushing services for pre-commissioning of new equipment, as well as maintenance or refurbishment of existing equipment to keep your topside and subsea equipment operating at peak performance.

Flushing Equipment We provide mobile, general service or zone-rated hydraulic flushing and test rigs for use in offshore installations, petrochemical plants, defense establishments, railways and shipping. Our flushing rigs have been specifically developed for use with mineral and synthetic oils to support pure flushing or flushing and pressure testing for a wide range of customized high velocity oil flushing, contamination control and oil and fuel purification services. Flushing units come equipped with sampling points for on-site oil analysis to test new fluid for cleanliness. And we offer portable microscope kits and automatic particle counters to verify hydraulic fluid cleanliness. We provide a variety of diesel-engine drive and electrical drive hydraulic and water based flushing units for long or short term hire. And if a more permanent solution is desired, Proserv has the ability to manufacture HPU’s/Flushing units to suit the client’s needs. Pressure Testing Services Proserv’s team of fully trained and experienced technicians ensure equipment is maintained to the highest possible standard with the appropriate certification. Our facilities comprise of several internal and external test pits for hydro testing (0 to 40,000 psi) and gas testing (0 to 30,000 psi). We provide clients with safe operating systems for the pressure testing of assemblies and components, and provide remotely controlled test systems allowing hydraulic flushing and testing to be controlled within a safe environment.

Topside Equipment Case Study

Proserv’s Technical Teams ability to solution engineer onsite a best fit for purpose installation with successful commissioning, rendered the system operationally on time.

A Global Leader in the Offshore Drilling Industry

Client: Drilling Contractor Location: Asia-Southeast Equipment: Marine Riser Tensioner Control Skid Technical Services: Medium Pressure Tubing Installation, Electrical and Instrumentation Installation, Welding and Control System Panel and Hardware Integration




The client was on schedule for a complete overhaul on one of their semisubmersibles, executing their 5 year Out Of Service (OOS) maintenance period. The client contracted Proserv to provide the design, manufacture and installation of a Marine Tensioner Control Skid to replace the existing system that reached the end of its useful life. The original unit was severely corroded due to its location in the Moon pool. And the materials and components used on the skid were discovered to be substandard for the type of environmental conditions.

Proserv began the design of the Marine Riser Tensioner Control Skid System that would monitor and operate 6 inline Marine Riser Tensioners on the semi-submersible in May 2015. System materials and components used in the design would now extend the lifespan of the equipment and include the same functionality as the original unit.

The Proserv technical crew encountered some challenges with the installation of the skid on the drilling rig but because of warranted experience with all styles of hydraulic, pneumatic, electrical and electronic control systems, the team was able to solution engineer onsite completing the project with a successful commissioning, rendering the system operational to the client by October 23, 2015.

Proserv’s technical service team installed all of the tubing, electrical and instrumentation of the new skid as well as the design and manufacture of the control system panel and integration of the hardware onto the rig.


Aftermarket Service & Repair Case Study Leading International Service Provider to the OIl and Gas Production and Processing Industry

Proserv’s broad service offering provided the client with an unexpected turnkey solution that kept total project costs in check and streamlined operations, producing an on time delivery for the end user.

Client: Leading International Service Provider Location: Niagra, New York Equipment: Compressor Skids Technical Services: Welding, Low Pressure Piping and Tubing Installation, Instrumentation and Electrical Installation and Structural Fabrication




Proserv was originally contacted for qualified experienced welders to perform butt welds on lube oil and process piping for two compressor skids that would be used to supply air for drilling equipment.

Once onsite, The Proserv team reworked a high percentage of the welds from the previous contractor successfully passing the secondary radiographic test from an outside party. The client was then made aware of additional services that Proserv could offer to complete the entire work scope of not only two compressor skids but a third one as well. Services required were Low Pressure Piping and Tubing Installation, Instrumentation and Electrical Installation and Structural Fabrication. Proserv was able to deploy the needed staffing within 24 hours so that project milestones could continue to be met without interruption.

Proserv’s ability to provide certified service technicians with a broad skill offering for the design, fabrication, and installation on all styles of drilling and production control systems; prevented the client from having to coordinate and manage multiple contractors.

The client was experiencing a high failure rate on the butt welds for the lube oil piping during radiographic testing from the workmanship of their existing contractor that would prevent a hard delivery date to be met.

The Proserv team also supported the client with consumable materials and heavy support equipment for the project to keep costs in check and assembly schedules moving forward.

Proserv’s additional team support of survey specialists, estimators and project managers provided the platform necessary to streamline operation processes rendering an environment that produced consistency in workmanship throughout the project scope.
