About Trafoser
A transformer and substation service company built around programmes — condition assessment, life extension, commissioning — for fleets in Europe, the UK, the Balkans, Türkiye, the Middle East and Africa, including sites where the capability is not local.
The service model
Most transformer service is sold one intervention at a time: the asset goes to a workshop, or a crew attends for a single outage. We are organised around the fleet instead. For a utility working to a regulated outage plan, that means a sequence of assessment, treatment and life extension timed to the windows the network allows. For a 40-tonne power transformer at a mine site nine hundred kilometres from the nearest port, it means the capability travels to the asset, arrives complete and works self-sufficiently for as long as the programme takes.
On remote and cross-border work, a large part of what we do is logistics, customs and planning rather than engineering. We treat that as part of the service rather than as the client's problem, because there it is what actually determines whether the work happens.
Certifications
We publish a certification only when it is held in a form we can evidence. Nothing is listed here yet.
Safety
Written for the HSE manager who will review us before the engineering is discussed.
Risk assessments and method statements (RAMS) are produced per task, not per contract. Permit-to-work, lock-out tag-out and switching discipline apply on every site regardless of what the site itself operates. Tank entry is treated as confined-space work with its own procedure and rescue plan. Arc-flash assessment determines PPE rather than habit determining it.
For remote deployments this extends to travel security assessment and medical evacuation arrangements. A team that cannot be extracted from a site should not be sent to it.
Environment
Oil spill containment and bunding on every site where oil is handled. Used oil is removed under a documented chain of custody and disposed of through licensed facilities — it does not become the site's problem after we leave. PCB screening is carried out where the age or provenance of the fluid makes contamination possible, and PCB-contaminated oil is handled separately.
Anti-bribery
We do not offer, promise, give or accept a bribe, a facilitation payment, or anything of value intended to improperly influence a decision. This applies to our staff, our agents and our subcontractors, and it applies where refusing costs us the work.
This is stated plainly because development-finance procurement requires the disclosure, and because a supplier who will not say it directly is telling you something.

A bid is usually rejected on documents before an engineer reads the technical submission. This list is what a tender process will ask for.
We would rather publish this and remove an obstacle than make you request it item by item.
None of these can be published yet. The section exists so that it can be filled the moment they can.
