Proserv Offshore - Subsea Maintenance, Abandonment and Decommissioning

Proserv Offshore is a global leader in subsea maintenance, abandonment and decommissioning, providing flexible and reactive engineering solutions from the installation and maintenance of a structure through to decommissioning at the end of its field life.

Offshore, onshore, topside and subsea structure removal services

We supply contracting, project management and engineering services associated with the removal of offshore, onshore, topside and subsea structures. These services include well plug and abandonment (P&A), removal preparation, pipeline abandonment, platform removal, site clearance verification, refurbishment and reinstallation, and regulatory compliance.

Due to our experience we make sure our services remain flexible, encompassing anything from single-well P&A to multi-platform abandonment and decommissioning programmes. We continually strive to make sure each project is completed safely, economically and on schedule.

Offshore structure abandonment services

We plug wells, flush pipelines, cut and extract conductors and remove subsea and other structures in a cost-effective and efficient manner, eliminating the need for multiple contractors on your project.

Rig-less well abandonment

Specialising in rig-less well abandonment, we also provide the planning and execution of multi-well platforms, single well caissons, inland water wells, subsea wells, storm-damaged well sites and structures, slot recovery, preparation for side track and internal or external conductor cutting.

Proserv Offshore's more than 20 years' experience in conducting well abandonments worldwide means you can be sure your project will be executed in the safest possible manner due to our proven track-record of meeting abandonment regulatory standards and exceeding the client's expectations.

Subsea and marine tools for ROVs and divers

Proserv Offshore provides a wide range of bespoke tooling solutions for marine and subsea operations that can be deployed by a diver or ROV. We also remain at the forefront of innovation through continued R&D of new products. We are considered industry leaders in:

• Cold cutting systems, including water abrasive, diamond wire and mechanical / reciprocal technologies
• Seabed dredging
• Cleaning and coating removal
• Friction welding systems

Our innovative range of equipment can be mobilised quickly and cost efficiently anywhere in the world, and has evolved from long experience of working in some of the most challenging environments, including the North Sea and the Gulf of Mexico.

Conversion to topside portable tools

Our cold cutting technology (including jet-cut water abrasives, hydraulic saws, friction discs and diamond wire) and our friction-stud welding (FSW) systems are also translated into a specialist range of portable onshore tools, ideal for use in hazardous environments.

High and ultra-high pressure pumps

Our large fleet of high and ultra-high pressure pumps is available for sale or hire, designed for zoned or un-zoned areas and operates in the most demanding environments on and offshore.

Our typical pumping and jetting capabilities include:

• Heat exchanger cleaning
• Cold cutting
• Spillage cleanup operations, UHP rust-scale removal, paint stripping and coating removal
• HP abrasive wet-blasting to provide uniform surface profiles
• Tube bundles, condensers and cooler cleaning
• Emptying and cleaning of production vessels
• Pipe work, de-scaling and flushing
• Pressure testing vessels, pipelines and valves
• Abrasive UHP cold cutting in hazardous areas
• Dust-free abrasive surface preparation
• Removal of non-skid coatings from helidecks and walkways
• General cleaning and maintenance work
• Vacuum unit services

Our 20 years' experience in this field ensures we can supply a system that perfectly meets your particular needs, from hydraulic units and power-packs to pump units and compressors. Our systems have been developed over many years of worldwide operation and as a result we have the technology and expertise to provide an effective and reliable service.
