Clearance was granted and USCGC Citrus was ordered to proceed and assist in fighting the fire. The burning ship arrived in Dutch Harbor on Jan 24 and advised that the fire was raging between the decks. Fire fighting parties from Citrus began assisting the crew of the Japanese vessel. USCG aircraft evacuated three patients from Seifu Maru to Kodiak for hospitalization. The fire assistance rendered by Citrus in a 4-Day operation saved the Japanese vessel.
