Tuhia he tohutoro mo tenei irava - I muri i tana whakahoutanga, i tukuna a "Sweetbrier" ki Cordova, Alaska. I te Hui-tanguru 1976, i a ia e haere ana ki tana mahi hou, i mate tetahi o ana kaipuke i te tauranga Navy Fuel Facility i San Diego i te wa i hinga ai ia i waenga i te kaipuke me te tauranga. I tae mai te "Sweetbrier" ki tana tauranga hou i te Poutu-te-rangi 1976. I reira ka haere tonu ia ki tana tiaki i nga awhina ki te whakatere, me te awhina i te kaipuke ika o te rohe, engari he whakaaro hou tana. E noho ana a Cordova i te pito rawhiti o te huarahi supertanker mai i te mutunga o te punaha Pipeline Trans-Alaskan i Valdez ki te Moana-a-Kiwa. I te 17 o Hanuere 1980 i ngaro te mana o te kaipuke hinu "Prince William Sound" e mau ana i te 831,000 peere o te hinu paraoa, a ka timata ki te rere ki te takutai. I whakautu a Sweetbrier, engari me nga pupuhi e eke ana ki te 70 knots kaore i taea te tiki i tetahi aho taraiwa ki te kaipuke hauā. I muri i te 16 haora e rere ana, ka taea e te "Prince William Sound" te whakaara ano i ona miihini me te haere humarie, engari i taua wa e ono maero noa iho i te takutai toka. I te Poutu-te-rangi 24, 1989, he kino ake te mutunga o tētahi atu kaipuke tino nui i runga i taua ara. Ko te "Exxon Valdez"
i rere ki runga i te Bligh Reef i Prince William Sound ka marara 10,800,000 US gallons (41,000 m3) o te hinu raw. Ko te "Sweetbrier" tētahi wāhanga o te urupare nui a te Kaitiaki Moana ki te rerenga. I whakahaerehia e ia te whakahaere waka rererangi, te tiaki i te whakatipu ika ika ika, me te whakatinana i te rohe ahuru huri noa i te kaipuke kaipuke.
