Dilt- og navigasjonsbøyer
Vi har et bredt utvalg dilt-bøyer tilgjengelig for bruk i overgangen mellom streamer lead-in over til streamer kabel. Siden 1990-tallet har vi levert slike bøyer til seismikkselskaper over hele verden, i størrelser fra 270 liter og opp til 2500 liter.
Våre navigasjonsbøyer er utviklet for å bistå deg med overvåking av posisjon og bevegelser, i tillegg til den tradisjonelle dilt-bøyefunksjonen. Navigasjonsbøyene er vanligvis utstyrt med en undervannsgenerator, solcellepanel, batterilader og en batteripakke, samt kundespesifisert posisjoneringsutstyr.
