About Us

Mentor Marine Consultants

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, correspondency 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. In 2023 our presence in Turkey was strengthened through the addition of our Izmir office.
Based in Greece & Turkey, we serve both the local and international market covering the most vital elements of marine activities with services tailor-made to meet our Clients expectations. Having listened to our Clients needs, claims, consultancy and risk assessment are included alongside all our survey work.
Our Clients cover the spectrum of those involved in the marine and insurance market and include H&M Underwriters, P&I Clubs (fixed and mutual), Charterers, Cargo Insurers and Financing Institutions. We also accept instructions from solicitors to provide expert testimony as technical consultants.
As well as covering the whole of Greece and Turkey through our network of tried and tested collaborators, we are regularly called to attend abroad in countries throughout the Balkans, Eastern Mediterranean, Middle East, Africa, South America, Europe and the countries of the former Soviet Union.
In our capacity as correspondents of various P&I Clubs and Insurance Underwriters, we are fully compliant with the latest GDPR (EE 2016/679) regulations and are holders of Professional Indemnity Insurance through ITIC. We are also ISO 9001-2015 Certified.
