John is specializing in the reviews of the vessel Specifications as well as the Plan Approvals for New Construction, usually carried out on behalf of the Owners. More specifically Plan Approval covering Machinery, Piping, Shafting, Propellers, Boilers, Pressure Vessels, Inert gas systems, COW, Electrical Drawings, etc. These reviews and Plan Approvals historically have covered Bulk Carriers, Container Vessels and Tankers. There is an accumulative experience of about thirty-five years in carrying out this type of work and some of the companies that he has worked with include FCN Management Inc., Diamlemos Shipping Corp., Equinox Maritime, Vrontados S.A., Chandris Hellas, Carras Hellas, amongst others.

The experience for carrying out the reviews of Specifications and Plan Approval was acquired through the 36 years he had been working with ABS from July 1973 to January 2007 and after his retirement, with Diamlemos Shipping Corp. company where he is still working to date.

Nineteen years of John’s ABS career was spent dealing with Surveys, repairs, modifications, statutory requirements, installation of new systems and other surveys on existing vessels, as a “Principal Surveyor”. In addition he was also involved in attending the New Construction of Bulk Carriers (15 vessels), Passenger (2 vessels), Tugs (3 vessels), Tankers (10 vessels), Refrigerated (2 vessels), High Speed Aluminum (2 vessels) and Aluminum Pleasure Yachts (4 vessels), in Greece (Perama, Eleusis & Hellenic Shipyards), Galatz Romania, Mokpo Korea and Shanghai China. This gave him the ability to familiarize himself to a great extent with a broad spectrum of vessel types and different systems.

Half-way through John’s career with ABS he was offered the opportunity to change discipline and he was transferred from the Surveyor Division, to the Engineering Division. After spending a year at the ABS London Machinery Technical Office for training he spent the remaining seventeen years in the Piraeus Machinery Technical Office as the Head of the Department and held the position of the “Principal Engineer”. During the time there, within the Technical Department, he familiarized himself with the ABS machinery Rules, and this gave him the ability to review the Specifications and carry out Plan Approvals in detail and to verify that the Classifications Rules are implemented, also proposing modifications to the different arrangements, thus upgrading the quality and efficiency of the systems of the vessel.

Presently and after John retired from ABS, he has been working for Diamlemos Shipping Corp. for fourteen years in the Technical department, being involved with Classification matters and technical aspects of the managed vessels.

John holds a B.Sc. Honours Degree from Newcastle Upon Tyne University in Mechanical Engineering and has received a Degree from the National Technical University of Athens in Mechanical and Electrical Engineering.

John was a Member of the Technical Chamber of Greece and was a Fellow of the Institute of Marine Engineers as well as a Chartered Engineer.
