skroget<br />
I motsetning til et skipsformet<br />
skrog der statiske vekter, tank<br />
fylling og bølgelaster gir<br />
betydelige globale spenninger på<br />
grunn av skrog bøyning vil det for<br />
en sylindrisk enhet praktisk talt<br />
ikke være globalspenninger og<br />
dimensjonene styres i stor grad av<br />
lokalkrav i form av flyt og buling.<br />
Beregninger gjort viser at det kun<br />
er side-struktur og forankrings<br />
festene som er dimensjonert av<br />
utmatting.<br />

Vinterisering<br />
Beskyttelse av personer og utstyr t mot vind,<br />
lave temperaturer, rein, sludd, snø og ising<br />
Områder som ikke inneholder hydrokarboner<br />
vil bli helt innelukket<br />
Prosessområdet vil ha tett tak og delvis åpne<br />
sidevegger for å sikre naturlig ventilasjon<br />
Dette gir store gevinster for arbeidsmiljø,<br />
reduserer behov for værbeskyttelse,<br />
gir mulighet for oppvarmede arbeidsområder<br />
og det gir en sikrere materialhandtering<br />

Bølgebryter på hoved dekk og<br />
værbeskyttelse rundt prosessen<br />
Bølgebryteren mellom hoved og<br />
prosessdekket er utviklet for å gi<br />
tilfredstillende arbeidsmiljø og<br />
lufting men og kunne ta ut kraften<br />
av impuls laster fra grønn sjø opp<br />
mot 10 bars trykk.<br />
For prosessområdet er ikke grønn<br />
sjø en aktuell problemstilling men<br />
her er det arbeidsmiljø, miljøutslipp<br />
og eksplosjonssikkerhet som har<br />
satt krav til designet.<br />
Prosess område som er dekket<br />
med et tett tak og har perforerte<br />
vegger. Veggene er relativt tette i<br />
nedre del og blir gradvis mer åpne<br />
oppover mot taket.<br />

Benefits of Being Cylindrical in Ice<br />
• Equal performance in all direction<br />
– No need for weather vaning<br />
– No ice crushing along vertical sides<br />
• Ice drift is unpredictable<br />
– Driven by wind and current<br />
– Typically following the tide<br />
(turning 180° 4 times a day)<br />
• Limited need for ice management<br />
– “Zero” turning circle<br />

Conclusions – Ice Tests<br />
ULS test conditions in ice ridges :<br />
- loads not exceeding the capacity of the mooring system<br />
- pitching < 5°<br />
- accelerations in surge and pitch – very minor<br />
- no ice travelling under the hull<br />
ULS level ice (1.9 m thickness) :<br />
- very moderate mooring system loads<br />
- pitching < 1°<br />
- accelerations in surge and pitch – very minor<br />
- no ice under hull for<br />
