DSP-06 SandQ Particle Monitor - Subsea
ClampOn - Norway
The ClampOn Subsea SandQ/Particle Monitor incorporates a new filtering technique that makes the sand detector an extremely useful tool for analyzing the nature of sand production, helping to control it and finally, increasing the economical output from the well! This filtering technique is the result of integrating our experience of thousands of wells, analyzing data, and using the results to enhance the technology used in our Subsea SandQ Monitor.

The enormous capacity of the DSP sensor (the only one on the market) makes it possible to scan through a frequency range of 1 MHz 128 times per second. This shows the capacity of our technology and of the filtering technique that is at the core of acquiring and processing sand data.
CEM - Subsea
ClampOn - Norway
The ClampOn Subsea CEM measures and monitors wall thickness loss in pipes, vessels or other metal structures. The instrument uses Acoustic Guided Lamb Waves (AGLW), with the result output of the average wall thickness reading for a large section of pipe. Transducer pairs operate in a pitch-catch mode and use the ultrasonic waves to give the average wall thickness between the transducer pairs. The transducers are fixed at pre-determined points on the pipe to monitor the wall thickness loss in sections of the pipe up to two meters long.

The subsea CEM can utilize up to 32 transducers, increasing distance to a maximum of 8 meters. Wall thickness trends are generated automatically and can be observed in real-time on a computer running ClampOn CEM software, or logged internally in a data logger.

Design depth is 3000m.
WTM
ClampOn - Norway
ClampOn’s Subsea (Max Operational Depth 2700m) WTM is a flexible tool designed for temporary installation and inspection at multiple locations. The instrument measures pipe wall thickness using the travel time of ultrasonic pulses. It is equipped with a piezo-electric element to provide precise wall thickness measurements in multi echo mode. The WTM is non-intrusive and can take measurements on coated pipes.

Data is stored in flash memory for fast and simple download and data analysis once retrieved, or be available as real-time measurement through an optional subsea cable-to-surface capability.
DSP Leak Monitor - Subsea
ClampOn - Norway

The theory is that a leak creates a very high-frequency noise that can be monitored by an ultrasonic sensor. In a «non-leak» situation the ultrasonic pattern will be constant, but when a leak occurs the signature will change dramatically. ClampOn’s DSP technology distinguishes and filters background noise unrelated to leakages so that the hiss from the leaks can warn the operator.

The ClampOn DSP Leak Monitor tsubsea version is designed to be installed at critical points such as valves, flanges, joints, etc., and can monitor very small leakages. A pressure differential of as little as 1 bar can be monitored in gases, and 3 bar in liquids.

DSP Pig Detector - Subsea
ClampOn - Norway

ClampOn PIG detection systems perform this operation in a simple way as they only monitor the PIG from the outside of the pipe. The sensor is simply clamped onto the pipe, and there's no any need then for welding or drilling during installation. The sensor is capable of detecting all types of PIGs.

The ClampOn DSP PIG Detector is a more compact and user-friendly unit than other instruments on the market. 

DSP involves complete digitalization of the system and the elimination of analogue filters. ClampOn is the only manufacturer of PIG detection systems to use DSP, which enables the sensor to operate in several frequency ranges simultaneously, eliminating the danger of the detector being triggered by noise sources other than PIGs.

3D Vibration Monitor - Subsea
ClampOn - Norway
The ClampOn Subsea 3D Vibration Monitor is a non-intrusive vibration and noise monitoring system. The system allows monitoring of vibration and acoustic noise signatures across an unusually wide range of frequencies, spanning from 0Hz to 262 144 Hz, depending on the application. Typical applications include condition monitoring, verification of operating conditions (e.g. for flapper valves), and evaluation of the structural health of pipes and supporting structures.

Ultrasonic Intelligent Sensors - topside

DSP-06 Particle Monitor - Topside
ClampOn - Norway
The ClampOn DSP-06 Particle Monitor is based on the ClampOn “Ultrasonic Intelligent Sensor” technology. The sensor is usually mounted in/immediately after a 90 degree bend, where the particles/solids impact the inside of the pipe wall, creating thus ultrasound. The ultrasonic signal is transmitted through the pipe wall and picked up by the acoustic sensor.

In the patented intelligent ClampOn sensor, the signal is processed internally by a DSP engine and filtered before being sent onwards to the computer or the control system (no Calculating Interface Unit required).
DSP SandQ - Topside
ClampOn - Norway
The unique, patented ClampOn SandQ® sensor provides operators focusing on sand management passive ultrasonic technology; it detects the ultrasonic signal that is generated by particles colliding on the inside of the pipe wall, right after the curve where the sensor is located. The instrument has onboard Digital Signal Processing (DSP) for analyzing of the data picked up by the instrument. Measurement is done in real time and results are continuously displayed on the control PC/system, giving the operator immediate and reliable data when a well starts producing sand.

The SandQ® offers
- Latest generation DSP

CEM - Topside
ClampOn - Norway
The working principle of the ClampOn CEM (Corrosion Erosion Monitor) is based on transmitting ultrasonic signals that propagate through the pipe-wall. The dispersive characteristics of a group of guided acoustic waves, called Lamb modes, are exploited to indicate a mean change in wall thickness relative to reference values acquired during the installation of the CEM system.

The permanently installed CEM system ensures that measurements are repeated frequently and in exactly the same manner, thereby eliminating the weaknesses of manual ultrasonic thickness gauging. Wall thickness trends are generated automatically and can be observed in real time.

Min Pipe diameter: OD 75mm (3”)
Pipe-wall thickness: 4 to 35mm (0,157 to 1,378″)
Distance between transceivers: 0.15m to 2m

Sensitivity: 1% of wall thickness. The presence of liquid in the pipe does not affect sensitivity.

Special Very Critical Service isolating products

Isolating kits & gaskets for pressure classes 150 & 300

Pikotek® PGE™
GPT - USA & UK
The Pikotek® PGE™ is a low-pressure service isolation kit designed for electrical flange isolation and/or general sealing applications
The PGE™ was designed to give operators an alternative to the failure prone phenolic-based isolating gaskets. The unique design of the PGE™ system incorporates patented overlapping and offsetting seal grooves. The purpose of this design is to break each layer of laminate within the gasket itself, thereby creating a barrier through which fluid and/or gas cannot migrate. The sealing element can be any elastomeric material, as well as more sophisticated spring-energized PTFE lip seals. As a result of this advanced seal design, maintenance-free flange isolation and flange face corrosion mitigation are achieved economically. Depending upon the sealing element selected, the PGE™ is rated for most hydrocarbon and water service applications.

This gasket is suitable for use in raised-face and flat-face flanges in ANSI Class 150 & 300 service (or equivalent). In addition to providing electrical isolation, the gasket is excellent for isolating flanges made of dissimilar metals or where prevention of flange face corrosion is desired.
LineBacker®
GPT - USA & UK
LineBacker® sealing gaskets use a rectangular sealing element, referred to as a "quad" ring, in combination with a unique groove design to effectively seal and isolate flanges of all types. Its unique quad ring design is providing elastic memory for elastomers not normally associated with this characteristic.
Materials such as PTFE, used as sealing elements, may dramatically increase the ability to match gasket materials to service conditions. This greater variety of materials also provides excellent temperature and chemical range compatibility. LineBacker® sealing gaskets are self-energizing with theoretical near-zero "m" and "y" factors resulting in a positive seal without excessive bolt loads - as are often required with flat gaskets.
