MT Wind is an Aframax crude oil tanker. Formerly known as Mastera for almost two decades and briefly as Mikines in early 2022, as Alma until September 2023 and as Petali until February 2025, she and her sister ship Tempera were the first ships to utilize the double acting tanker (DAT) concept in which the vessel is designed to travel ahead in open water and astern in severe ice conditions. The icebreaking tanker was built to transport crude oil year-round from the Russian oil terminal in Primorsk to Neste Oil refineries in Porvoo and Naantali.
