Todo list:

  1. Check that all systems are functionon (integration)
  2. Document current stability
    a) Weight individual components as much as possible and calculate mass/volume.
    20.04.2022:
    DONE
    b) Weight the platform as is and correlate to previous calculations in a)
    20.04.2022:
    All weights have been broken down, paired, and added to excel sheet.

  3. Calculate necessary changes to increase stability (in porpotion to the new payload)
    a) Recomended that the winch has a follower arm that locks the wire from translatorical movement around centre of mass for better response to wirepull
    20.04.2022:
    Payload weight is still unknown, but with prelimanary calculations it was obvious that 6 pillars were not enough for new design.
    right now the platform has a -2,4kg buoyancy without: ROV, battery compartment, Winch motor, or the added mass from expanding the frame. 

  4. Execute necessary changes
    a) Find the most unintrusive design addition for batteries and additional flotation
    b) Redo wiring in the electronics compartment
    c) prepare the top frame for new winch and controlbox.
  5. Test and document new stability
  6. Test in ocean (inkl. all systems in prt

Viktige arbeidsoppgaver:

  1. Sjekke at alle systemer fungerer (integrasjonen)
  2. Dokumentere nåværende stabilitet
    a) veie indiviuellekomponenter så langt det lar seg gjøre. samt balansere komponenter for å finne massesenter.
    b) fåreta en veiing av platform for å korrelere utregninger.
    c) Har familiemedlem i COSL drilling europe som kanskje kunne anskaffe stabilitets software.
  3. Beregne nødvendige endringer for økt stabilitet (med hensyn på ny nyttelast)
    a) fåreslår at vinsj får en nedsenkbar arm rundt vaier slik at horisontale bevegelser blir påført rundt massesenter og så derfor minimalt påvirkning av plattform
  4. Utføre nødvendige endringer
    a) dele opp nederste rør i 3. Midterste for plassering av 12V batteri
    b) Bruke hjørnene av de nederste pongtongene som ballast. IKKE stolpene.
    c) potensielt flytte thrustere til hjørnene for å få thrust nermere ballasten
    d) sette inn vannbarriærer hos ballasttank for å negere forflyttning samt øke stabilitet.
    e) bruke normale 12v bilbatterier for ballast og strøm.
  5. Teste og dokumentere ny stabilitet
  6. Teste ny plattform i sjø (inkl. alle systemer i pkt. 1).
