Brownfields represent a large share of the energy industry. In order to secure pipeline integrity in existing fields, it is vital to monitor pipe condition. In other words, ClampOn can install retrofittable, non-intrusive sensors to secure your Brownfield assets.
ClampOn can assist on the following Subsea operations:
Below is the list of ClampOn products available for Brownfield assets:
The ClampOn funnel and clamp can be retrofitted to existing structures and our non-intrusive acoustic instrumentation can then be installed by ROV. Usually the installation of the funnel/clamp and the instrument can be done in one operation.
The Vibration Monitor can be used as a standalone inspection tool. The Vibration Monitor can then be installed on pipes and structures exposed to vibration. However, the instrument do not need to be in contact with the pipe. There are several solutions for clamping the instrument to the structure being monitored, including a magnetic clamp.
The ROV installable funnel can be adapted to any pipe size larger than 4″. Note that this funnel is suitable for all ClampOn acoustic and magnetic instruments where the tip of the sensor must be in contact with the pipe surface.
Faced with the challenge of vibration on a 2″ pipe, we had to lower the weight impact of our instruments as much as possible to avoid adding resonance to the structure.
With this in mind, the ClampOn design team developed a detachable handle that could be removed by ROV after installation
Vibration Monitor with a magnetic mount (100kg downforce). As a result, this gives a stable platform for monitoring vibration and has a minimum impact with regards to weight on the pipe structure. To point out, this Vibration Monitor can easily be relocated.
With the simplicity of magnetic installation, the operator can then easily mount the non-intrusive vibration monitors on a pipe structure and monitor phase relationships.
The non-intrusive ClampOn Corrosion-Erosion Monitor (CEM) monitors changes in wall thickness over a given area. As shown below, we have two sets of transducers mounted on a pipe or bend. The transducers send and receive signals to and from each other, and as a result we are able to monitor up to a 1 meter long length of pipe.
This instrument is designed by ClampOn to be installed by a diver. Transducer rings with supports tailored to the pipe dimensions. This allows for simple installation by a diver. The canister has been made lighter and is designed to be installed on an I-beam.
This is a Corrosion-Erosion Monitor designed to be retrofitted to a pipe by ROV.
The data from the ROV mounted instruments can be retrieved in many ways, for example:
Via cable: Directly into the SCEM, piggyback on an existing cable or tethered directly to an ROV for spot measurement.
Wireless: Radio link
Onboard storage: For retreieval of data at a later date.
