Paradigm Flow Solutions Launches Pipe-Pulse to Revolutionise Removal of Subsea Blockages

HOUSTON, May 4, 2011 - Paradigm Flow Solutions today launched patented technology to tackle the
persistent industry challenge of restrictions and blockages in subsea
pipelines, taking the treatment to the topside for the very first time.

Paradigm also revealed at the Offshore Technology Conference in Houston
that it has just landed a $250,000 contract with a super-major to unblock a
pipeline in the North Sea and has secured more than $1 million of orders for
its other technologies in the last two months.

The Aberdeen headquartered company says that subsea blockages cost
operators tens of millions of dollars each year, which before now could only
be properly treated by very expensive methods such as deploying a coiled
tubing system from a rig into the pipeline, or undertaking subsea
interventions using a Remotely Operated Vehicle (ROV) or saturation divers.

Pipe-Pulse is a remote, non-intrusive method of locating and removing
blockages in long distance pipework up to 30 miles. The system is designed to
be connected on the topside facilities of the host platform through either
the pig launcher or the umbilical termination unit to clear the blockages.
The Pipe-Pulse unit delivers high energy and volume pressure pulses into the
pipeline or subsea umbilical, which are transmitted at the speed of sound to
the blockage several miles away.

Operated by Paradigm Flow Solutions' team of expert engineers, persistent
blockages can be completely removed in a matter of days by sending high
frequency low amplitude pressure pulses into the flowline, whilst controlling
the length and pressure of the pulse. The system operates using a complex
series of control valves, which are contained within the main body of the
Pipe-Pulse unit, that are automatically operated by the touch screen control
panel. Proprietary algorithms determine the optimum wave structure for each
pulse, of which there are potentially millions generated for each particular
job. The Pipe-Pulse unit then physically creates and injects the manufactured
pulse into the pipeline, which is then transmitted to the front face of the
blockage. These controlled pulses allow energy to be transferred into the
pipeline in a safe manageable way, which is far more effective than applying
pressure alone.

During test phases it successfully cleared a 4" multi-phase flowline for
Shell UK that had been blocked with sand and wax for 11 years, and also
removed a stuck pig in a deepwater 8" flowline for Petrobras Americas. The
Pipe-Pulse system is also used to accurately detect the location of blockages
and leaks in subsea infrastructure, without the need to deploy expensive

Rob Bain, managing director of Paradigm Flow Solutions said: "Subsea
blockages and restrictions have been a challenging industry problem for many
years. Pipe-Pulse effectively revolutionises the treatment of subsea
blockages, taking the treatment to the topside for the first time. It is
fantastic that we are able to launch it to market with a contract for the
North Sea already secured. Given the cost implications of the alternative
methods, Pipe-Pulse provides an appealing, fast-acting, cost effective

The company, a subsidiary of the Netherlands-based Paradigm Group,
developed the innovative Pipe-Pulse service in direct response to flow
assurance and integrity issues being experienced by global operators.

Mr Bain previously worked at Shell and BG Group for over 22 years
including deepwater subsea engineering and management roles in the UK and US.
The company, which launched in 2010, employs 19 people and is developing a
range of technologies for detecting, remediating and preventing subsea and
topside blockages.

The US is a prime target for its technologies and the company is opening
an office in Houston this year and a recruitment drive will soon get
