Whakaotihia te rerenga e whai ake nei: I te Hōngongoi 2, 1987, i patua e te kaipuke hinu "Glacier Bay" tētahi mea i raro i te wai i Montague Strait, ā, i maringi atu i te 125,000 taranata hinu. I haere te kaipuke ki tētahi wheketere i Cook Inlet mai i Valdez, Alaska, i te wā i puta ai te raruraru. I tonoa a "Sedge" hei pokapū whakahau rere mō ngā kaipuke e 21 e ngana ana ki te whakahoki mai i te hinu. I te 24 o Poutu-te-rangi 1989, i kino ake te mutunga o tētahi atu kaipuke hinu i Valdez.
Ko te "Exxon Valdez" i rere ki runga i te Bligh Reef i Prince William Sound i te waipuke o te hinu raw. Ko te "Sedge" te kaipuke tiaki takutai tuatahi ki te whakautu ki te waahi. I whakauruhia he punaha Whakauru Wai Tuwhera me te Whakaora me te "Sedge" i neke atu i te 8,900 peera hinu mai i te moana. I nga waahi rereke i te wa o te urupare mo te rerenga, i whakahaerehia e ia nga rangahau takutai me nga mahi whakahaere waka rererangi. I te tau 1990 i hangaia e te kapa o te "Sedge" te rama rama e tohu ana i te Bligh Reef inaianei.
