Ships

Principia has been supporting the success of ship development projects worldwide since 1981. Our track record covers projects for all ships:

Navy ships (frigates, aircraft carrier, submarines),
Passengers ships as Cruise and ferries,
Merchant ships (tankers, LNG, container ships),
Specific ships (scientific, new concepts),
Oil and gas service ships.

We deliver expertise and engineering design services applied to these ships, from the early design stage to the detailed studies. We offer also expertise in case of emergency situation or administrative enquiries.

Principia has offices in France, Singapore and Houston and can provide expertise and engineering services worldwide.

Services

Our scope of services covers today :

Design studies : Preliminary Design of Yachts, Supply Boats, FPSO, barges, etc.,
Hydrodynamic studies : Sea-keeping, Roll damping, Stability, Hull and appendage definition, CFD analysis for hull resistance and viscous effects,
Fluid structure studies :Sloshing, Coupling effects,
- Structure studies : strength assessment, finite element analysis, calculation notes for Rules, Fatigue calculations,
Dynamical studies : vibrations, comfort onboard, impacts, slamming,
Security aspects : simulation of accidental events onboard (collision, explosion), evacuation, flooding, survivability, time to sink, grounding, pollution, stability after damage, …
Ship Engineering : conceptual design of barges, vessels (weight report, stability report, general arrangement, …),
Fuel consumption economy and security onboard system,
Embedded systems onboard : stability, strength assessment monitoring, line shaft bearing monitoring, etc.
Specific Monitoring systems development and installation onboard.

Principia also offers privileged access to some of the main French high technology model test basins.

For 25 years, our expertise in core scientific disciplines as structural design, fluid-structure interactions, hydrodynamics and fluid dynamics has built upon multi-sector research and development activities (naval, marine, renewable energy, nuclear, space, automotive,..) and partnership with National research centres, Universities and engineering schools.

Principia is also involved in thematic networks:
ISSC, ECMAR, MARSTRUCT
ATMA, GICAN, BV technical days,
Pôle de compétitivité MER PACA et BRETAGNE
