Arbeids- og kompetanseområde
Jeg har doktorgrad på marine strukturer (NTNU, Norge). Doktorgradsoppgaven handler om påvirkning av skip og isfjell, der jeg utviklet analytiske og numeriske metoder for å beregne islastene. Min master og bachelor er på marinearkitektur og havteknikk (begge i SJTU, Kina). Jeg har også mer enn 10 års erfaring fra olje- og gassindustrien med fokus på design og integritetskontroll av ulike offshore -strukturer.
Mine ekspertise er på følgende områder:
1. Finite element analysis (FEM) av Abaqus Implicit/Explict eller ANSYS/Ls-Dyna
2. Sjøarkitektur og havteknikk, inkludert SURF -konstruksjon, konstruksjonsdesign, marin drift, tretthetsvurdering, feltutvikling og integritetsstyring etc.
3. Slagmekanikk. Skipskollisjon, tapte gjenstander og eksplosjon etc.
4. Arktisk ingeniørfag inkludert ismekanikk og struktur-is-interaksjoner etc.
5. Programmering i Python/Fortran/Matlab. Før- og etter- dataprosess, overvåket maskinlæring.
ING2049 Undervannsteknologi og hydrauliske systemer
