Proserv is a leading Technology Services company for the global energy industry

Friction Welding Technology

Friction Welding Process and Features

• Attachment of a stud to a structure by producing a solid phase forged weld between the stud and the substrate

• Certified welding to ASME IX • Proserv provide a portable system/service • Topside or underwater applications

Technology Developments – Subsea Stud Changer

• Previously weld head assembly limited to returning to the surface with the ROV to replace the stud

• New design ROV deployed weld head assembly

Subsea Stud Changer – Technology Applications

• Wind turbine pile studs for anode strap attachment

• Pipeline studs for anode strap attachment

Technology Developments – Tripartite weld

• Developed and refined to weld three parts together in one operation.

Tripartite weld – Technology Applications

• Anode attachment • FPSO (220 Kg x 220 off)

• Sensor attachment

Technology Developments – Plug Repair

• Development of friction stud welding technology for plug type repairs

Water Abrasive Cutting Technology

Technology Development - MSC

• Multi String Cutting (MSC) Tool – remotely operated from the surface

• Used to severe wellhead completions below the mudline

MSC – Technology Applications

• US campaign • NS campaign

Dredging Technology

Technology Development - ROV Dredge

• Improvement to existing dredge design by relatively simple changes • Resulting in 400% improvement in the vacuum pressure

Dredge– Technology Applications

• Challenge - to remove 1,500 m^3 material from under a platform • Project drivers

• 2 off ROV Dredges

• 2 off Hybrid Dredge Systems (2 dredges in parallel with 70 m suction hose)

Coating Removal Technology

Pipeline Coating Removal

• Requirement to remove various coatings such as concrete, bitumen, polypropylene and fusion bonded epoxy's quickly and efficiently from subsea pipelines

• Proserv specialise in high pressure water jetting to remove the coatings

Technology Development – Pipeline Coating Removal

• Current limitations of technology • Technology developments

Marine Growth Removal Technology

Technology Developments – Marine Growth Removal

• Engaged to assess the vulnerability of ROV interfaces to marine growth within an operational field

• Highlighting vulnerable areas and operational considerations • Investigation of existing industry tooling and gaps in the market • Development of full range of tooling for marine growth removal and mitigation

Marine Growth Removal – ROV Tooling

1. Hydraulic hot stab and electrical connector extraction system

2. Stabplate removal tooling package 3. Stabplate override separation jack 4. Shrouds for both the stabplate fixed and free

plates 5. SCM and mounting base shrouds 6. Acid injection systems
