Mentor Marine Consultants was founded in 1992 by John C. Cratiras and Nicholas E. Mariakis in response to the increasing demand by the marine sector for quality technical services. Over the years we have grown into a highly specialised and experienced technical firm that provides a wide range of consultancy and survey services to the marine sector whilst maintaining a strict adherence to our core values of honesty, clarity and discretion. In 2018, Mentor Marine Consultants - Istanbul was established, based in Istanbul, Turkey.
