I started working offshore in 1982 as a commercial Diver having worked as a mechanical engineer from leaving school until that time, in 2000 I gave up diving and started working as a system technician on diving systems, eventually rising to the position of a mechanical technical supervisor within the diving industry.
I first became aware of the Mini-Ductor when discussing the issues around naked flames with a colleague, as everyone is aware in the oil and gas industry the issues around this are manifold. 
Having ordered a Mini-Dudctor for the vessel I was working on at the time I cannot express the virtues of this tool highly enough, I would like to list some of the uses and advantages below.
- Firstly, the tool is capable of producing heat to free ceased bolts and fittings without producing a naked flame, so the danger of ignition of fuel vapour or gas is greatly reduced.
- Next, the tool can be used at height without the danger of falling sparks thus reducing the necessity of a large exclusion zone around the work site.
- Minimal training for the use of the tool, unlike the use of oxyacetylene.
- When working within the 500m exclusion zone of a platform there is no requirement to shut down UV sensors on the platform that would be required with say oxy-acetylene or the use of a grinder.
- When working in confined areas this tool can be used without fear of a build-up of dangerous gasses, as would be the case with a heating torch.
- The tool can direct heat in a very localized area reducing the necessity for the precautions necessary with a naked flame.
- The tool is self-contained, requiring only a power lead, this is unlike the use of a heating torch, this reduces trip hazards and the danger of damage to flexible hoses and the uncontrolled escape of explosive gasses.
- No danger of monoxide poisoning due to faulty gas heating equipment.
- Finally, the tool is many times more environmentally friendly than other heat sources that require the burning of fossil fuels.
I believe that any tool that can reduce the risk of personal injury in a significant way should be readily available to anyone working in the hostile environment of the oil and gas industry, I believe this induction tool has that ability.
