SDC Ship Design & Consult GmbH

Founded 1997 by Dr.-Ing. Harald Jensen, Hamburg Ship Model Basin (HSVA) and Germanischer Lloyd (GL), nowadays owned by Harald Jensen and HSVA, SDC Ship Design & Consult GmbH has grown to a full-scale design consultancy, offering the complete set of naval architectural and engineering services for ships and offshore structures to ship owners and shipyards.

By now, SDC’s staff provides expertise in all aspects of ship design, starting with stability, passing by strength analysis and engineering heading towards project management and site inspection.

Partnerships and closest co-operations not only with our co-founders but also with highly specialized experts perfect SDC’s offer to ships still an idea as well as to ships sailing the seven seas.

Ship design and corresponding support is one of the core business areas of SDC and includes for example:

  • Concept designs
    (resulting in technical contract documents as a basis for shipbuilding contracts)
  • Basic-/Class Designs
    (including key plans and main documents for approval of the classification societies and administrations, used as the basis for the detail design)
  • Design support
    e.g. stability calculations, weight estimation, speed-power predictions, escape way, freeboard, fuel oil tank protection calculations etc.
  • Major Conversions
    Concepts and basic design for e.g. lengthening, widening, ship type change, LNG retrofit
  • Minor Conversions
    e.g. bulbous bow optimizations, emission reductions and scrubber refits, ballast water management calculations, reefer boosts, ballast water treatment layout, draught/deadweight increase, IHM


From the beginning it was our goal at SDC to support shipping companies and shipyards in evaluating the technical implementation of their ideas incorporating latest rules, developments and research results. SDC’s designs are tailor-made solutions based on sound naval architectural principles, integrating all aspects from the operational and shipbuilding side already in the concept design phase.

The scope of vessels, SDC has handled is simple: nearly everything that floats, from inland waterway barges to cruise liner and mega yachts.

It will be a pleasure for us, working together in the GeMaX community to keep highest quality and knowledge for shipbuilding and shipping in Germany alive.
