Profile bio

About Stuart Duffield Afni, Avi

I am an experienced Master Mariner (Captain) and Marine Assurance Professional, with extensive command experience and an in-depth knowledge of marine operations including SMS and PMS, compliance, BRM and DP operations, which I use to provide superior marine assurance services including inspections, surveys and audits of marine assets, accident / incident investigations and legal services. I have provided consultancy services for numerous marine clients including Oil Majors such as Shell, Chevron and BP. I was recently engaged to lead investigations into a major and costly LTI in which a suspended load lowered into the sea during equipment testing. I oversaw a robust investigation and established the cascade failure that caused the incident, then embedded preventative procedures to eradicate future risk of failure. An engaging and collaborative Captain, I use my exceptional interpersonal skills and lead by example to motivate and inspire personnel to work to the best of their abilities, and to maintain that dedication and professionalism throughout the duration of a project. I am politically savvy with meticulous attention to detail, able to appraise, interpret and adhere to regulatory requirements and adapt to changing situations and unexpected issues swiftly.
