Our southern operation works out of Totton, on the western edge of Southampton, covering the South of England for on-site and facility-based inspection. This is what we actually do from there, what the work looks like locally, and how to get hold of us.
Where we are
Unit 4 Nutwood Way, Totton, Southampton, Hampshire, SO40 3WW.
That puts us minutes from the M27 and the western docks, and within comfortable reach of the whole south coast — Portsmouth, Poole, Bournemouth, Salisbury, Winchester and Basingstoke are routine day work, and we cover further afield when the job warrants it.
What we do from Southampton
Site radiography. Industrial radiography on client sites, with all the IRR17 machinery that implies — prior risk assessment, controlled area, RPA support, surveyed boundaries and dosimetry. Source selection is made to shrink the controlled area where the geometry allows, because on a working site the size of the boundary is usually the constraint that decides whether the job can be done at all.
Ultrasonic testing and phased array. Weld inspection, thickness surveys and corrosion mapping. Encoded phased array where a permanent, re-examinable data record matters — which on pressure equipment and anything with a fitness-for-service argument behind it, it usually does.
Surface methods. Magnetic particle on ferritic material, dye penetrant on austenitic and non-ferrous, both colour-contrast and fluorescent depending on the sensitivity required.
Weld inspection. Visual and dimensional examination to ISO and ASME acceptance criteria, welder and procedure witnessing, and the paperwork that has to survive an audit afterwards.
Positive material identification. On-site XRF for alloy verification and material traceability. One thing worth stating plainly because it catches people out: XRF does not measure carbon, so it cannot separate 304 from 304L or 316 from 316L. Where the carbon grade genuinely matters — and in chloride service it often does — that needs OES or laboratory analysis, and we will tell you which your job needs rather than issuing a certificate that overstates what the instrument did.
Coating inspection. Surface preparation standards, dry film thickness, adhesion, holiday detection and the environmental limits that void a coating warranty.
The work the south actually generates
The mix here is different from our Cumbria base, and it is shaped by what is on the coast.
Marine and port infrastructure. Structural steelwork, cranes and lifting equipment, quayside plant, and the joints where salt air has been working on them for twenty years. Corrosion mapping and remaining-wall work rather than new fabrication.
Marine engineering and shipbuilding. Hull and structural welds, pipework systems, and the classification-society paperwork that goes with them.
Process and chemical plant across the Solent industrial belt — pressure systems, storage, pipework, and shutdown work where the inspection window is fixed and short.
Fabrication shops needing third-party inspection on production work, welder qualification testing, and procedure qualification support.
Aerospace and precision engineering in the Hampshire supply chain, where the sensitivity requirement is higher and fluorescent methods in controlled conditions are the norm rather than the exception.
Construction and structural steel, including bolted connection verification and weld inspection on structures going up across the region.
Why the location matters more than it sounds
Two practical reasons, both about time rather than distance.
Mobilisation. An inspection contractor four hours away turns a two-hour job into a day and prices it accordingly. It also makes a re-shoot or a complementary method a second mobilisation rather than an extension of the first — which is the cost that hurts, because it is the one nobody budgets for.
Shutdown work. Turnaround inspection is scheduled to the hour, and it moves. A crew that can be on site the same morning when a vessel opens earlier than planned is worth considerably more than one that cannot, and that is a function of being local.
One group behind it
The Southampton operation is not a standalone. It draws on the same quality framework, the same Level 3 personnel and the same laboratory as the rest of the Test Inspect Group.
In practice that means a site job here can send coupons to our Cumbria laboratory for tensile, Charpy impact to 300 J, hardness and macro examination without you engaging a second supplier — which matters most on welder and procedure qualification, where site witnessing, NDT and destructive testing all have to arrive at one certificate. One provider, one chain of evidence.
It also means components too awkward to radiograph in place can go to our radiation compounds, which take components up to eight metres, and be shot under controlled conditions instead. Where a component is coming out anyway, that is almost always cheaper, faster and lower-dose than taking a source to it.
Planning a shutdown inspection
Most of what we do here is turnaround work, and the jobs that run well share the same preparation.
Agree the acceptance criteria before the outage. Not during it. An indication found at 2pm on day three with no agreed criteria costs a day of everyone's time, and the crew is standing by while it is resolved.
Establish access with the scaffold plan, not after it. Inspection is routinely the last trade considered and the first to be blocked. A scaffold designed for a coating crew frequently will not put a technician where a probe needs to be.
Decide what gets cleaned, by whom, to what standard. Surface preparation is the single most common cause of an inspection over-running, and on shutdown work an over-run has nowhere to go.
Identify what can be inspected off-site. Anything being removed anyway is almost always faster, cheaper and — where radiography is involved — lower-dose examined in a controlled facility than in situ. This is the largest single saving available on most outages and it is usually decided by habit.
Book the window, not the day. Radiography in particular needs an area clear of other trades, and that is a scheduling negotiation better had in advance than at 7am with three contractors waiting.
Reporting
Results are recorded at the component on a tablet, into structured forms with the acceptance criteria for that job already loaded, and reviewed as they are recorded rather than typed up days later.
The practical effect on a fabrication job: welds shot in the morning are released or flagged by the time the crew packs up, so a repair starts that afternoon instead of the following week. The gap between an inspection finishing and a decision being possible is where most of the cost of inspection actually sits, and it is the part nobody prices.
Getting hold of us
Call +44 (0)1946 372220, Monday to Friday 8am–4pm, with 24/7 emergency response for genuine outages.
If it is a scoped job, the most useful things to have to hand are the component and material, the standard and acceptance criteria that apply, the access, and when the window is. If you do not have all of that, call anyway — working out what the inspection should actually be is a normal part of the conversation, and it is better done before the crew mobilises than at the component.
TECHNICAL REVIEW — DELETE FROM THE LINE ABOVE, DOWN
