Our Specialist Maritime Team

Director

Geraint has about 35 years of formal risk management experience in complex organisational and technological settings. He gained this experience during 20 years as a Royal Navy nuclear submarine officer, and subsequently as Manager Operational Risk with Air New Zealand. Subsequent risk management focus has been in the maritime and aviation sectors as well as more broadly covering organisational risk management and risk governance.

Geraint’s naval experience included time both as a systems technician and as a graduate systems engineer, licenced nuclear propulsion  supervisor and chartered member of the IMarE. Sea experience was also gained on both large surface ships. His last navy posting was as a squadron engineer with responsibly for the assurance, support and operation of a flotilla of 13 nuclear and conventional submarines. He also held roles in site and nuclear safety and nuclear emergency response.  Later maritime operational experience includes roles as the safety manager for the attempted salvage of the RENA, as the operations manager for the salvage of the KEA TRADER off of New Caledonia, regional harbourmaster for Otago and the development of maritime safety management systems and safety cases.

Geraint’s experience both in operational and consulting roles within civil aviation has enabled him to apply leading aviation safety and assurance management thinking and methods to the maritime sector, while his engineering background enables a systems approach to problem solving.

Geraint was the New Zealand representative for the development of the first global risk management standard ISO31000 (risk management), assisted the Australian delegation on the development of ISO31010 (risk assessment techniques)  and has been the Chair of the national professional body, Risk NZ.

Having sailed since childhood Geraint as a natural affinity for the sea.
