D. THOMAS MARINE HELLAS S.A. through its consulting engineering services offers leading edge technological solutions in design work.
Our group’s mission is to provide quality services of high standard within the requirements set by our customers.
To serve this scope, we use skilled employees and state of the art marine software.

Our team consists of:

DESIGN WORK

Our team has been involved in numerous design projects over the years. Using our integrated software packages (Autoship, Simsmart, B.V. Steel) they are capably covering all aspects of ship design i.e. from Hull modelling, to structural design (both global and local), and detailed design of piping systems. Using our experience from our appraisal and plan approval work as well as the consulting work carried out on the implementation of various regulations, we produce novel design concepts. Our study group with high academic background are involved in many study tasks for our clients that complies with all Class societies.

MAJOR & MINOR CONVERSIONS

Our engineers have been involved in various conversion projects from design work to attendance during construction. There has been extensive involvement in compartment re-arrangement of general cargo vessels (re-arrangement of decks and cargo holds, fitting of CO2 compartments, re- arrangement of tanks, etc) as well as retrofitting of deck equipment (addition of cranes, removal of cranes, vapor control systems, etc). The studies related with conversion work are accomplished by using our state of the art software for FEA, stability, longitudinal strength, as well as CAD for the production of the necessary structural drawings.
Some work has been done in other kinds of conversions like increase of ship’s length and conversions of CBT Tankers to SBT for compliance with MARPOL requirements.
Our work also includes conversion of single Hull tankers to double hull according to IMO regulations.
