Basic Naval Engineering

Wide variety of disciplines:

  • Conceptual design.
  • Feasibility.
  • Naval architecture calculations.
  • Accommodation basic engineering.
  • Structure basic engineering.
  • Services basic engineering. Schemas.
  • Technical specifications for equipment and materials.
  • Contractual specifications.
  • Purchase specifications.
  • Stability calculations:
    • Intact stability.
    • Damage stability (Deterministic and probabilistic methods). 

We also develop basic engineering for specific modification projects, repairs and retroffiting of new equipment on ships in service, being specialiced in the Alfa Laval equipment installation, of which Aries is the Agent in Spain.

With more than 45 years of experience in the Naval sector, Aries provides high quality and excellent results in the execution of their projects, and can thus successfully confront all the works requested by our customers.



Aries carried out the conceptual design of an oceanic research vessel to replace Cornide de Saavedra owned by Instituto Español de Oceanografia (IEO), capable of research operations in any sea in the world. A technology excellence ship, ready for a wide variety of scientific works with the best accommodation facilities for all the people onboard.
