MV Plancius, formerly HNLMS Tydeman (A906), is a renovated oceanographic research vessel of the Royal Netherlands Navy now employed as a polar expedition cruise vessel by owner and operator Oceanwide Expeditions. She was commissioned into the Royal Netherlands Navy on 10 November 1976, and served until 2004, before being renovated for commercial use. The vessel was used for both military and civilian research and had a fracture zone named after it.
Designed for oceanographic and hydrographic research, Tydeman measures 90.2 metres (295 ft 11 in) long with a beam of 14.4 m (47 ft 3 in) and a draught of 4.8 m (15 ft 9 in). In naval service the vessel had a fully loaded displacement of 2,977 tonnes (2,930 long tons ). [1] [lower-alpha 1] The ship is powered by a diesel-electric system composed of three Stork-Werkspoor 8-FCHD-240 diesel engines and one motor turning one shaft creating 2,040 kilowatts (2,730 hp ). [1] Any two of the three diesel engines power the propulsion while the third engine powers the ship. [2] The vessel also mounts a Paxman diesel engine creating 362 kW (485 hp), an active rudder creating 220 kW (300 hp) and two bow thrusters creating 360 kW (480 hp). [1] This gives the vessel a maximum speed of 15 knots (28 km/h; 17 mph) and a range of 15,700 nautical miles (29,100 km; 18,100 mi) at 10.3 knots (19.1 km/h; 11.9 mph) or 10,300 nmi (19,100 km; 11,900 mi) at 13.5 knots (25.0 km/h; 15.5 mph). [2]
Tydeman was designed for military and civilian research and had a maximum complement of 62 including 8 officers with an additional 15 civilians. [1] [2] The vessel had six laboratories [1] and mounted a flight deck and hangar large enough to operate small helicopters. [2] [lower-alpha 2] In naval service, the ship had a forward working deck with a wet hall and midships and aft working decks, along with diving facilities and two container spaces for 6.1 m (20 ft) standard shipping containers. The ship has passive stabilisation and can operate oceanographic cables to depths of 7,000 m (23,000 ft). The vessel was equipped with Atlas DESO-10 echo sounders, EDO-Western type 515 deep sea echo sounder, ELAC-Mittellodar wreckage sonar, Geometrics G-801 magnetometer, bottom diggers, radiosondes, barometers and Kelvin Hughes, hull-mounted side-scan sonar. The vessel mounted one 10-ton crane and one 4-ton crane with frames. [1]
Ordered in October 1974, the vessel was constructed for the Royal Netherlands Navy by BV de Merwede at their yard in Hardinxveld-Giessendam, Netherlands, and the keel was laid down on 29 April 1975 with the yard number 612. [1] [3] The vessel was launched on 18 December 1975 and commissioned on 10 November 1976. [1] The vessel was named after Vice Admiral Gustaaf Frederik Tydeman, a hydrographer of the Siboga Expedition (1899–1900) in the Dutch East Indies. [4] Used for civilian and military research, the vessel became the namesake of the Tydeman fracture zone (36°N 23°W), between Madeira and the Azores which was part of the project investigating the area in 1977. [5]
From March 1991 to March 1992, Tydeman trialled a derivative version of the Thomson-Sintra DUBM 41 towed sonar system. This was followed by a major refit from April to November 1992 at the aan der Giessen-Noord shipyard. From 1996 to 1997, the research ship trialled the TSM 2670 2-ton active low-frequency sonar body and passive towed sonar array. [1] The ship was taken out of service in June 2004. [6] [7]
After retiring from naval service, the vessel was acquired by Oceanwide Expeditions and in 2009, the ship was converted to a passenger/cruise ship. The vessel returned to service in 2009, with a 3,434 gross tonnage (GT) and 700 tons deadweight (DWT). [3] The vessel was ice-strengthened, rated at 1D and accommodates 108 passengers. The vessel 40 cabins measuring 12.5 m2 (135 sq ft) and 10 cabins measuring 21 m2 (230 sq ft). The vessel carries 10 zodiacs and a crew of 37. Tydeman was renamed Plancius and sails under the Dutch flag, used for cruises to the Arctic and Antarctica. [7]

: CS1 maint: url-status (link)The Delfinen-class submarines were the first class of submarines constructed for the Royal Danish Navy following World War II. They were designed and built within Denmark, with first three boats of the class financed by Denmark. The fourth was financed by the United States under the Cost Share program. Constructed between 1956 and 1963, the class comprising four submarines entered service in 1961 and the last taken out of service in 1990. Replaced by the Norwegian Kobben class, three of them were scrapped while a fourth was converted into a museum ship and remains on display at the Aalborg Maritime Museum.
The Ouragan class was a series of French landing platform docks operated by the Marine Nationale. They were designated Transport de chalands de débarquement (TCD) in French service. The Ouragan class was the first series of landing platform docks designed and constructed by France. The two ships entered service in the late 1960s and both ships saw service in the Pacific Ocean as part of the French nuclear programme. They were initially intended to be replaced by the Foudre-class landing platform docks in the 1990s. However, due to delays, they were kept in service until they were replaced by the Mistral-class amphibious assault ships in the 2000s. A possible sale to Argentina fell through after concerns of asbestos arose. Both ships were taken out of service in 2007 and were scrapped in Belgium in 2016 and 2017 respectively.
The Durance class is a series of multi-product replenishment oilers, originally designed and built for service in the French Navy. Besides the five ships built for the French Navy, a sixth was built for the Royal Australian Navy, while the lead ship of the class currently serves with the Argentine Navy. Two ships of a similar but smaller design are in service with the Royal Saudi Navy as the Boraida-class replenishment oilers.
The Almirante Padilla-class frigates is a series of frigates operated by the Colombian Navy. The designation of this class is Type FS 1500 and there are four ships in service. The ships were built by Howaldtswerke-Deutsche Werft (HDW) at Kiel, West Germany in the 1980s, with the first vessel commissioning in 1983 and the last in 1984. The frigates have undergone significant modification over their careers with the 2012 Orion Program Upgrade significantly modernising the vessels. Two similar ships operate as the Kasturi-class corvettes in the Royal Malaysian Navy.
The Type 704 Rhön-class tankers are a series of replenishment oilers used by the German Navy to provide underway replenishment for its ships at sea. The two vessels in the class, Rhön and Spessart, were originally constructed for Libya by Kröger Shipyard in Rendsburg, West Germany as bulk acid carriers. They were acquired by the West German Navy in 1976 for conversion and entered service in 1977. The two ships are crewed by civilians. In 2019 it was announced by the German Navy that the ships are planned to be replaced in 2024.
USS Newport (LST-1179) was the third ship of the United States Navy (USN) to bear the name of the Rhode Island city. The first of her class of landing ship tanks (LST), she was capable of a sustained speed of 20 knots. Her ability to adjust her draft, accompanied by her unique bow-ramp design, helped bring a new degree of responsiveness to the amphibious fleet. The ship was launched in 1968 and entered service with the USN in 1969. Assigned to the United States Atlantic Fleet for the entirety of her career, Newport made deployments to the Mediterranean and Caribbean Seas. The vessel was taken out of service in 1992 and laid up until 2001.
The Vidar-class minelayers consists of the two ships, HNoMS Vidar and HNoMS Vale built by Mjellem & Karlsen in Bergen for the Royal Norwegian Navy in 1977 and 1978. Used as multi-role ships, the Vidar class were tasked with minelaying, personnel/cargo transport, fisheries protection, torpedo-recovery ships and as anti-submarine warfare escorts in Norwegian service. In 2003, Vale was transferred to the Latvian Navy via donation and renamed Virsaitis and used as a flagship and tender to patrol craft. In 2006, Vidar was transferred to the Lithuanian Navy and renamed Jotvingis and served as flagship and tender to mine countermeasures craft. Both vessels had their ASW equipment removed upon transfer.
The Kortenaer class was a class of anti-submarine frigates of the Royal Netherlands Navy. Like other frigate types of the 1970s and 1980s, they featured a COGOG propulsion system with separate cruise and sprint gas turbines. Ten were built by de Schelde in Vlissingen and two by Wilton-Fijenoord in Schiedam between 1978 and 1982. Only ten served with the Royal Netherlands Navy: two were sold to Greece while still under construction and replaced by two Jacob van Heemskerck-class frigates which were an anti-air warfare variant of the Kortenaer class. The Greek frigates were renamed the Elli class. After service with the Dutch ended, eight of the frigates were sold to Greece in 1992 and the remaining two to the United Arab Emirates. Three of the ships have since been retired from active military service with one converted into the superyacht Yas.
The Tripartite class is a class of minehunters developed from an agreement between the navies of Belgium, France and the Netherlands. A total of 35 ships were constructed for the three navies. The class was constructed in the 1980s–1990s in all three countries, using a mix of minehunting, electrical and propulsion systems from the three member nations. In France, where they are known as the Éridan class they are primarily used as minehunters, but have been used for minesweeping and ammunition transport in Belgium and the Netherlands, where the Tripartites are known as the Alkmaar class.
The João Belo class, also known as Comandante João Belo class, is a class of four frigates of French design, based on the Commandant Rivière class but fitted for tropical service. Ordered by the Portuguese Navy in 1964, the four ships of this class were constructed at the shipyard in Nantes, France between 1965 and 1967. The first ship entered Portuguese service in 1967. The frigates were used for ocean patrol of Portuguese colonies and later, joined NATO's STANAVFORLANT unit. The first unit was discarded in 2003, followed by a second in 2004. The final two ships were taken out of service in 2008 sold to the Uruguayan Navy. The third ship was discarded in 2021, with one ship remaining in service.
USS Fresno (LST-1182) was the fourth tank landing ship (LST) of the Newport class. Fresno was named for a county in California. The vessel was constructed by the National Steel and Shipbuilding Company in San Diego, California and launched in 1968. The ship entered service in 1969 and was assigned to the United States Pacific Fleet, taking part in training along the west coast and operational cruises to the western Pacific, taking part in the Vietnam War. Fresno was decommissioned in 1993 and laid up. The LST was nearly sold to Peru but remained in the U.S. inventory until 2014, when Fresno was sunk as a target ship in the Pacific Ocean during a training exercise off Guam.
The Poti class was the NATO reporting name for a group of anti-submarine warfare (ASW) corvettes built for the Soviet Navy. The Soviet designation was Project 204 small anti-submarine ships. These ships were the first Soviet warships powered by gas turbine engines; two propellers were mounted in tunnels to give a very shallow draught. A twin 57 mm (2 in) gun mounting provided self-defence. Three ships of the class were exported to Romania and six to Bulgaria during the Cold War. By 2008, all ships of the class were no longer extant.
The French tanker Somme is a Durance-class command and replenishment tanker of the French Navy. In addition to its primary duty as a fleet tanker, Somme is configured as a flagship and has served as such in the Indian Ocean. The vessel was constructed at La Seyne, France beginning in 1985 and entered service in 1990. In October 2009, the ship was mistakenly attacked by pirates off the coast of Somalia. The attacked was repelled and the pirates captured.
BAP Abtao (SS-42) is an Abtao-class submarine of the Peruvian Navy. The vessel which was originally named BAP Tiburón ("Shark"), was constructed by the American Electric Boat company in the United States and launched in 1953. The Abtao class were the last submarines constructed by the United States for the export market. The submarine entered service in 1954 and by presidential decree, was renamed Abtao for the battle during the Chincha Islands War.
The Abtao class were four submarines of the Peruvian Navy that entered service between 1954 and 1957. They are also known as the Lobo class and the Dos de Mayo class and were constructed in the United States to a design based upon the United States Navy's Mackerel class. They were the last submarines to be constructed by the United States for the export market. All four submarines were powered by a diesel-electric system and armed with six 21-inch (533 mm) torpedo tubes. Two of the submarines also mounted a 5 in (127 mm)/25 caliber gun. The four submarines, initially named for animals, were all renamed in 1957 for famous Peruvian battles. Beginning in 1991, the submarines were taken out of service, with the last decommissioned in 1999. One, BAP Abtao, is a museum ship located in Lima, Peru.
The Akar class is a series of two replenishment oilers and fleet support ships, designed and built for service in the Turkish Navy. The lead ship of the class, TCG Akar, was constructed in 1982–1983 and entered service in 1987. The second ship, TCG Yarbay Kudret Güngör, was constructed in 1993–1994 and entered service in 1995. Both ships were constructed in Turkey, though Yarbay Kudret Güngör was the first ship built for the Turkish Navy by a private shipyard. Both vessels remain in service.
The French submarine Romazotti (Q114) was a Lagrange-class submarine built for the French Navy built between 1914 and 1918, during World War I. It was laid down in the Arsenal de Toulon shipyards and launched on March 31, 1918. Romazotti was completed in 1918 and served in the French Marine Nationale until 1937.
The French submarine Antigone was an Armide-class diesel-electric attack submarine originally ordered by Greece. It was built in the Schneider-Creusot shipyards between 1912 and 1917, but was requisitioned on 30 May 1917 by the French Government before it was delivered. Antigone operated in the Mediterranean during the course of World War I and was stricken from the Navy list in August 1935.
KRI Oswald Siahaan (354) is an Ahmad Yani-class frigate operated by the Indonesian Navy. Prior to her service in the Indonesian Navy, she served in the Royal Netherlands Navy as Van Speijk-class frigateHNLMS Van Nes (F805).
ARA Bahía Paraíso was an Argentine navy auxiliary ship and later sunk in 1989 2 miles (3.2 km) from Palmer Station at Arthur Harbor, Antarctica, resulting in a 170,000 US gal oil spill.
