Proserv offers a wide range of industry leading cutting equipment and services for marine and subsea operations for use within remote and challenging environments, suited to both topside and subsea applications. Using the company’s in-house manufacturing capabilities and expertise, we are continually developing new tooling solutions in order to meet complex engineering project requirements worldwide.

The Proserv Diamond Wire cutting system is ideal for IRM and as part of abandonment and decommissioning projects.

Available in several sizes ranging from 4 -14 in (100 mm - 355.6 mm) to 62 - 90 in (1,574 – 2,286 mm) in diameter, each tool in the range can cut through various materials and protective coatings and can be handled and operated by any work class ROV or surface deployed. The system’s independent power supply from vessel provides increased convenience and we have also developed a control system and fine metering valves to optimise efficiency in the cutting process.

Features & Benefits

• Work is carried out by a team of experienced personnel• The compact design of the tooling and its light weight provides for less deck

space and some tools in the range (DWS 42-70) are now built in 2 sections to provide easier and more economic airfreight transportation

• Constructed from marine grade aluminium alloy and 316 stainless steel, our range is lighter in weight with increased corrosion resistance and greater structural strength

• Buoyancy can also be added to reduce the weight in water to less than 100 kg • The Proserv Diamond Wire tools can be used on any tubular subsea structure

as part of the removal or repair operations including pipelines, caissons and jackets as well as TCP2 & TP1 deck separation and risers, offering a robust tooling system for use in hazardous environments that is safe and harmless to the marine environment

Proserv’s Dual Band Saw has been designed for cutting any tubular structure topside or subsea. It has been developed to cut pipeline, caissons, jackets etc ranging from 304.8-762 mm (12-30 in) in diameter. Made from marine grade alloy and stainless material, this makes the saw corrosion resistant, reducing its weight and aiding its structural strength. With the option of added buoyancy, the weight is reduced to less than 100 kg in water. The Dual Band Saw can be surface or ROV deployed.

Features & Benefits

• Corrosion resistant• Surface or ROV deployed• Built-in buoyancy, making the weight in water less than 100 kg (220.4 lb)• Capable of cutting any subsea structure between 304.8 - 762 mm (12-30 in)• Can cut through all types of protective coating• Dual option available - Diamond Wire or Mechanical Band Saw

Proserv’s Double Drill Pin is designed to provide an efficient method for securing multiple casing strings for safe recovery operations. When used in conjunction with Proserv’s other severence service products, they provide a unique and cost effective solution for well abandonment and slot recovery.

The Double Drill Pin is provided with 101.6 mm (4 in) or 152.4 mm (6 in) shell cutters which enables holes to be drilled from both sides of pipe with very short time cycle. The simultaneous safe recovery of multiple casing strings reduces the number of handling operations. The drilling is a cold work technique for use in environments where hot work is not permitted.

Features & Benefits

• A heavy duty double drill for drilling and lifting pin holes• Capable of drilling holes in single or multiple grouted casings• A modular design with handling points eases installation and operation• Fully designed and approved with certified load pins• Enables simultaneous recovery of multiple casing strings• Reduces number of handling operations• Especially suited to abandonment operations where adjacent wells may still

be in production• Less deck space required for recovered casings• Suitable for use in zoned or un-zoned environments

The HP Water Jetting Unit uses a patented HPW-pump, which is a reciprocating, double acting, hydraulic piston pump. This develops pressure in the delivery (water) line by transforming the actuating fluid power, usually hydraulic oil, into pumping fluid power; this is defined by the supplied flow rate and pressure to the pump.

These systems are specifically designed for integration with industry standard workclass Remotely Operated Vehicle (ROV) systems. The system delivers water at high pressure through a turbo (rotating point) nozzle which combines the advantages of fan and point nozzles in one unit.

The system is designed for ease of installation and maintenance and is robustly constructed to resist corrosion and so enhance environmental protection, a variety of specifications can be provided upon request.

Features & Benefits

• The system is designed for ease of installation and maintenance and is robustly constructed to resist corrosion and so enhance environmental protection, a variety of specifications can be provided upon request

• Up to 10,000 psi units available on request

The Proserv Internal Pipe Cutter (IPC) is deployed on its own umbilical and lowered into the pile utilising the vessel crane, cherry picker or winch wire and is monitored by the Proserv operator. Once the spreader beam has landed out on top of the pile, the IPC is centralised by its integral centralisers ready for cutting pending final functional tests. The circumferential movement of the cutting head is controlled using hydraulics, with the cutting process monitored by a radial encoder, which gives the operator accurate real time readings of the nozzle position within the pipe.

Features & Benefits

• Bespoke engineering applications• Ideal for cutting jacket legs and piles• Variety of IPC’s available to suit most size requirements• Accurate cold cutting• Creates a clean cut profile• The cutting angle can be altered to suit any specific requirement• Diver and ROV compatible• Proserv can also supply a pile dredge system to allow internal cutting below • sea bead level• Range of tools available capable of cutting from (but not limited to) 141mm

The Proserv Multi-String Cutting (MSC) Tool provides complete well severance from tool deployment to cutting operation and tool recovery within 12 hours. The tool is a customisable internal multi-string conductor cutter that is utilised in conjunction with Proserv’s water abrasive cutting technology to provide a superior cutting solution. This powerful combination is more efficient than conventional mechanical cutting methods and more environmentally friendly than explosives.

The tool is currently configured to deploy into topside or subsea wells with inner casing sizes of 178 mm (7 in) minimum to 508 mm (20 in) maximum and will cut through any number of internal grouted casing strings out to a maximum diameter of 914.4 mm (36 in) OD.

Features & Benefits

• Single trip deployment into well bore minimises risks associated with multiple runs in hole

• No need for special permitting and minimal crew required for operation• Modular, stackable system is quick and easy to set up and doesn’t require

integration onto drill-pipe• Small equipment foot print saves on deck space• Deployable into subsea wells and wells that run casing to the surface• Ability to test and prove the cut without recovering and de-rigging the tool

and deployment system• Provides real time cutting analysis to minimise risk of no pull• Equipment spread is based on more than ten years of reliable water

abrasive cutting experience• Uses field proven in-house designed lock and seal for tool centralisation

and clamping to the inside of the casing
