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.

Warm regards,

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.

Product Features Multiple cameras and lights can operate fromone system

Small form factor enables installation in tightlocations

High performance camera modules.

Key Benefits Easily operated and rapid set up

Maximum visibility in poor conditions (camera inclose proximity to point of interest)

mCrane BoomThe Claxton crane boom camera makescrane operations safer.

The Claxton crane boom camera is designed to assistcrane operators in ensuring the safe movement of loadseven in blind locations - making crane operation saferand faster.

The system, built using the same robust technology asour industry-leading subsea and downhole cameras,can be installed on virtually any type of crane operating inany environment.

Product Features Best-in-class 312:1 zoom capability

EEx rated modules provided for controlled zone,or cross zone applications

High-resolution daylight viewable LCD monitor

Custom designed pivot bracket and dampingsystem maintains a steady view of the work site.

Key Benefits Unmatched visual performance - class leadingzoom capability and high quality monitor system

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.

Actual output from CamScan projects

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.
