Structural analysis and expertises

One of the outstanding competences of Neptun is the field of static and dynamic structural analyses. Within the design of ships and steel structures as well as for the mechanical engineering all the miscellaneous structural analyses are done by means of efficient computation programs as ANSYS, RFEM (Dlubal), GL-Frame (Poseidon) and other. Neptun's state of the art analyses are characterized by incorporation of newest rules and regulations.
