What our clients think


COMET helped us understand the systemic root causes

"The main value to LR of adopting COMET is the newfound organisational leadership education and enlightenment as to the reasons behind incident types, particularly  those which hurt us most in terms of frequency. A recent example was repeat microsleep incidents affecting our surveyors. COMET helped us understand the systemic root causes and gave the Board sufficient confidence to invest over £2 million in a preventive action programme which is already bearing fruit in terms of this type of incident reduction."

James Pomeroy,
Group Director HSEQ at Lloyds Register

We’re maximising its value across the business

"Viridor is a relatively recent adopter of the COMET RootApp tool but is already beginning to really reap the rewards of a first class investigation system.
We’re maximising its value across the business through consistency of approach and ensuring we really do get to the root cause of our incidents so we can set the right actions to prevent recurrence.

The STC team has been hugely helpful and supportive in getting this new process implemented."

Richard Robinson,
Head of SHQS at Viridor

Probably the best root cause analysis process and toolkit

"Probably the best root cause analysis process and toolkit. But beyond enabling us to adequately identify root causes, COMET also allows us to track trends using the root cause codes to help address systemic opportunities in our management system."

Bertrand Piredda, Director of HSES Cummins Power Systems

Feels more like a partnership

"Borr Drilling adopted COMET across the business in 2017/2018 and since then our relationship and trust with the STC INSISO COMET team has grown immensely.

Any issues are quickly resolved or addressed and a feature of the relationship I enjoy most is that it feels more like a partnership than that of a more traditional vendor/client arrangement."

Thomas Sunde, QHSE Director at Borr Drilling

Positive and encouraging feedback

"STC INSISO recently delivered the 3-day COMET practitioner course to GSK R&D (UK) engineering and safety professionals.

The COMET team created a bespoke course that was well received by GSK R&D with lots of positive and encouraging feedback."
