Customer story: Babcock

A global company, Babcock Australasia (external link)(Babcock) employs approximately 1900 people in Australia and New Zealand. Here, they are the Strategic Partner (Maritime) to the New Zealand Defence Force, repairing and maintaining the Royal New Zealand Navy fleet. Babcock also operates the Defence Force’s IANZ-accredited calibration labs which, in turn, support hundreds of companies around the country.

Babcock Calibration Services Manager Edward Smulders said the company’s relationship with MSL is equally broad, and includes the electrical, temperature, and length, teams.

“MSL provides three crucial services to Babcock. They calibrate our transfer standards so that we can maintain that traceability. We also utilise a lot of their training courses –vital for keeping our team up to speed and up to date – and they carry out proficiency testing. Additionally, MSL scientists are very often the technical experts chosen by IANZ for our audits.”

“MSL allows Babcock to operate with confidence. If MSL didn't exist, there'd be no calibration in New Zealand, no traceability, no reliability for measurement. They not only provide certainty for us; they also provide it for New Zealand.”
