Technical Interpreting & Translation · Oil, Gas and Energy

In the field, a wrong technical term stops the operation.

Technical meetings, audits, commissioning, HSE and training — where a mistranslated safety instruction or specification costs time, money and risk. Technical interpreting and translation backed by more than two decades in high-complexity environments.

What's at stake

In energy, technical communication is part of safety

A specification translated literally that changes a tolerance. An HSE instruction misunderstood in the field. An interpreter who doesn't know the difference between upstream and downstream and stalls a technical meeting with the foreign supplier. In your sector, that isn't noise — it's downtime, rework and safety risk.

My job is to make sure technical teams from different countries understand each other precisely: correct terminology, engineering context preserved and no ambiguity where it costs dearly.
