    Since being founded in 1985 Claxton has earned an

    enviable reputation for service and responsiveness

    in fact a recent survey of our customers found that

    these two things set us apart from the competition.

    Our camera range is just one example of this customer focus in

    action: We have supplied world-class cameras for over 12 years and

    in response to the issues faced by clients, weve continually adapted

    and improved our range to meet their needs.

    We have several pioneering products in our camera range and these

    are offered alongside a deep range of engineering and services for

    subsea and land operations so customers can be sure that our

    cameras really benefit from Claxtons 25 years of oilfield experience.

    The result is that our cameras are rugged, field-proven and available

    for rapid call-off because thats what our clients told us they need.

    We hope that you find this brochure useful and look forward to

    hearing from you soon.

    MultiC

    amMultiCamDisposable camera systems withindispensable performance.

    Operations dictate it is often preferable to leave itemssubsea rather than to incur retrieval costs - Claxtondesigned MultiCam to meet this need while maintainingthe high visual performance associated with moreexpensive systems.

    Multiple cameras can be used to monitor stab guidesand other key areas to ensure a safe and accurateinstallation and to verify that infrastructure has beensuccessfully locked down.

    UltraLowLigh

    t A state of the art camera module providesvisual clarity in nearly pitch-black conditionsand deep water environments.The Claxton Ultra Low Light camera works effectively inconditions where light is poor or the sea is murky. Usinga light source in water with a large amount of particulatematerial normally results in bloom as the particles reflectthe light. Our system negates this issue by eliminating theneed for high powered lighting.

    Product Features Effective in light levels down to just 0.0003 LUX

    Camera module rated to 3,000m (300bar)

    Robust, easy operation control unit

    Fully field-proven system components.

    Key Benefits Ideal for low-clarity waters, such as those in theNorth Sea

    Reliable visual performance for applicationswhere silt is stirred up during operations

    Standard file formats for easy transfer.

    CamScan provesvital to successfultiebackCamScans powerful combination of high-spec featuresand quality visual performance has made it the de factocamera of choice for tieback operations.

    The Problem A tieback operation had been halted due tosuspected dropped objects downhole in KilmarWells 43/22-1 and 43/22-2.

    The Solution Claxton mobilized a CamScan system with LEDinternal lights to provide strong illumination andmaximum visibility

    CamScan was deployed downhole and the operatorused the pan and tilt function of the camera toquickly locate the position and orientation of junk forsubsequent fishing operations.

    The Result The camera provided vital visual feedback andclear images of the location and nature of theobjects

    CamScan was instrumental in inspecting thetieback threads and checking for further debristhroughout the tieback campaign

    Following the deployment of CamScan the tiebackwas completed successfully.

    MultiCam verifieswell installationIts often the case that simple, robust solutions can usurpmore sophisticated systems as MultiCam proved on arecent project providing visual verification beyond thereach of an ROV.

    A client had seven subsea Xmas trees to install as part ofthe Callanish and Brodgar Field developmentprogram. However due to access limitations, an ROVcould not be used to verify the installation. Views wererequired at the following locations

    Wellhead lockdown indicator

    Flow line hub lockdown indicator

    Guide post engagement

    In order to provide the necessary verification, Claxtonsupplied a suite of low cost MultiCam systems andmounting brackets to monitor these key locations.

    Case studies

    The Problem High currents and low Subsea visibility, at timesless than 3, restricted ROV capability and riskeddelays in the completion programme

    Viewing angles unobtainable using an ROV due toaccess constraints

    The cameras had to be mounted withoutresorting to direct modification of the trees.

    The Solution Simple unidirectional cameras mounted on the treestructure to provide positive confirmation of theindicators actuation

    Claxton designed a fully extendable, fullyadjustable mounting bracket that clamped to theexisting structure

    A weak link system enabled the umbilical to beretrieved and the camera/light assemblies to stay inplace on the tree once the installation was verified.

    The Result All camera assemblies functioned successfully andprovided the expected data without any loss of time

    The Xmas tree assembly was installed successfullywithout delays.
