An icebreaker is a special-purpose ship or boat designed to move and navigate through ice-covered waters, and provide safe waterways for other boats and ships. Although the term usually refers to ice-breaking ships, it may also refer to smaller vessels, such as the icebreaking boats that were once used on the canals of the United Kingdom.
MSV Fennica is a Finnish multipurpose icebreaker and offshore support vessel. Built in 1993 by Finnyards in Rauma, Finland and operated by Arctia Offshore, she was the first Finnish icebreaker designed to be used as an escort icebreaker in the Baltic Sea during the winter months and in offshore construction projects during the open water season. Fennica has an identical sister ship, Nordica, built in 1994.
MT Petali is an Aframax crude oil tanker. Formerly known as Mastera for almost two decades and briefly as Mikines in early 2022 and Alma until September 2023, 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.
La Noumbi is a floating production storage and offloading (FPSO) unit operated by Perenco. The vessel, converted from the former Finnish Aframax crude oil tanker Tempera by Keppel Corporation, will replace an older FPSO unit in the Yombo field off the Republic of Congo in 2018.
Ice class refers to a notation assigned by a classification society or a national authority to denote the additional level of strengthening as well as other arrangements that enable a ship to navigate through sea ice. Some ice classes also have requirements for the ice-going performance of the vessel.

MT Indiga was an ice-strengthened product tanker that sailed under the Finnish flag in 1976–2003 and under the Russian flag in 2003–2021. After her modernization in 1994 she became the second merchant ship, after her sister ship Varzuga, to be equipped with an electric azimuth thruster called Azipod.
A double acting ship is a type of icebreaking ship designed to travel forwards in open water and thin ice, but turn around and proceed astern (backwards) in heavy ice conditions. In this way, the ship can operate independently in severe ice conditions without icebreaker assistance but retain better open water performance than traditional icebreaking vessels.
CCGS Jean Goodwill is an icebreaking anchor handling tug supply vessel (AHTS) converted to a medium class icebreaker for the Canadian Coast Guard. She was originally built as Balder Viking for Trans Viking Icebreaking & Offshore AS in 2000. The vessel was sold to Canada in 2018 and was initially expected to enter service in late 2019 following a refit. However, due to delays the conversion of the vessel was not completed until November 2020.
