Company

Founded in Piraeus by G. N. Pratikakis, on a family tradition of forty years in ship design and shipbuilding.

Naval architects, marine and structural engineers, draftsmen.

Our team has held key positions at shipyards, engineering companies and classification societies. We bring that experience to owners and operators in shipping, shipbuilding and environmental protection.

In the East Mediterranean we are known for large scale conversions, structural engineering and new building concept design: the work that keeps a passenger fleet modern, safe and economic.

Island Greece runs on ferries, but...

  • A ferry rounding a headland on its way into port

    ...the fleet is ageing.

    Many ships on domestic routes are decades old. Conversions, re-engining and structural renewal keep them in class and in service.

  • Aerial view of a rocky Aegean coast with a small harbour

    ...ports are small and seasonal.

    Narrow entrances, short quays, winter swell and a summer peak five times the winter load. The hull has to fit the route, not the other way round.

  • A red hull on blocks in dry dock

    ...fuel rules are changing.

    Emissions pricing and fuel standards now reach passenger shipping. LNG, hybrid propulsion and shore power are design questions, not afterthoughts.

  • Mountains seen from the open deck of a ferry

    ...passengers expect more.

    Open decks, garages that load fast, cabins and lounges that make a six hour crossing part of the holiday.

Our answer is design that fits the islands.

01

Right-size hulls

Length, draft and manoeuvring sized to the ports a ship will actually call at, with the speed the timetable needs and no more.

02

Conversions that add decades

Lengthening, sponsons, new garages and accommodation, re-engining: structural engineering that gives a proven ship a second life.

03

LNG, hybrid and shore power ready

Fuel systems, tank arrangements and electrical balance designed to current rules, from the first sketch to class approval.

04

Support through the ship's life

Fleet management, surveys, dry dockings and casualty investigation. Available around the clock to our customers.

New building concept

A 145 metre LNG ferry for the Aegean, with approval in principle from Lloyd's Register.

Designed with Helengi Engineering and HydroComp for Blue Star Ferries inside the EU co-funded Poseidon MED II programme, and presented at the Royal Institution of Naval Architects in Rotterdam. Built to Safe Return to Port, the IGF Code and SOLAS.
