Hakkımda

Naval architect with a Ph.D. in hydrodynamics (from 1999).
Highly specialized in structural analysis.
Principal Engineer for DNV Energy Aberdeen, intended for class approval or third part verification of offshore structures.
Former Structural Design Approval Engineer (HO External Approval Unit) for Germanischer Lloyd Romania - member of Germanischer Lloyd Group – in charge with examination and approval of the hull structural drawings from the local shipyards.
Significant experience in the design and approval of the specific structures of container vessels, oil / chemical tankers, bulk-carriers and not only.
Significant experience for the handling of various technical situations (including a large range of design restrictions – technical, economical or human) in order to achieve the safety requirements.
Close cooperation with all the parts involved in shipbuilding – starting from the designers, through the quality and production departments and the owner representative - up to the final customer.
Trained as field surveyor too.
Basic training (entries levels) in ND Testing (US), ISM, QA ISO 9000 rev. 2000 and project management.
I am highly interested to join or to cooperate with a dynamic team involved in naval architecture / ship structure design or research – all over the word.
I enjoy challenging new situations and I am a team-orientated person.

Specific experience and achievements:

- Scantling of the ship structure (according to the classifications rules)Experience with a various types of vessels: dry cargo vessels / container vessels / oil tankers / chemical tankers / bulk carriers / ro-ro vessels / patrol boat.Scantling of special structures as rudder and nozzle and areas as aft area (rudder/nozzle area) or thruster areas (aft and fore).

- Structural analysis using FEM method (direct computation and checking)As alternative to scantling or for special analysis (complex or optimum structures) or modifications of the initial design (as result of special requests or design / conversions / construction errors)Special calculations for:Ro-Ro / Container vessels / Oil tankers / Dry cargo vessels / Desalination barge / Bulk carrier – self un-loader

- Solid knowledge of Rules and RegulationsIn detail knowledge of the classification rules and an inside understanding of the classification societies way of thinking. Good knowledge of statutory rules and regulations (SOLAS / MARPOL / LLC)Professional grew in safety and client satisfaction philosophy.

- Newbuilding structural surveyThe survey of the block section units starting to plates / elements assembly stage to units joint - trough all steelworks stages.The survey of the mounting of the rudder and shaft line.The survey of the hull outfitting, piping systems (bilge / cargo / oil / fuel), lifting appliances, life saving systems and equipments (anchor and mooring) – including survey at manufacturing plant.Types of vessels surveyedContainer vessels / Oil tankers / Barges / Inland LPG

- Welding and materials surveyThe survey of the welding procedures and qualification tests. The survey of the special welding processes (tick high tensile steel / special steel) and of the non-destructive tests (gamma ray / US / Magnetic Particle / Penetrating Liquids). Survey and certification of the materials.

- Specific works in ship stabilityLoading Manuals, Damage Stability Calculation, Inclining Tests according to the actual Rules and Regulations. Documents approved and tests surveyed by Germanischer Lloyd, Lloyd Register of Shipping and former Romanian Register of Shipping.

- IT abilitiesSoftware development. Programming in Pascal language for specific purpose.Computer literate: daily user of Windows applications and MS Office programs package. Solid knowledge of spreadsheet computations (Excel), basic data base building and interrogation (Access) and slide presentations (PowerPoint).Internet user for communication and documentation.
