HMS Protector is a Royal Navy ice patrol ship built in Norway in 2001. As MV Polarbjørn (Norwegian: polar bear) she operated under charter as a polar research icebreaker and a subsea support vessel. In 2011, she was chartered as a temporary replacement for the ice patrol ship, HMS Endurance and was purchased outright by the British Ministry of Defence in September 2013.
Service history (Norway)
Polarbjørn was designed and built for long Antarctic expeditions and for supporting subsea work. Polarbjørn was equipped to DP2 class and had accommodation for 100. Large cargo holds and open deck areas provide storage capacity for ROVs and related equipment. A 50-ton knuckle-boom crane and the 25-ton stern A-frame allow equipment to be deployed over the side and over the stern.
Polarbjørn worked in the "spot" market, on short-term charter. During 2009, the vessel was chartered for electromagnetic survey work in the North Sea, Norwegian Sea and Barents Sea. She was exposed to a downturn in business during 2010, with only a 33% utilisation.
Prior to the Royal Navy charter, she underwent a ten day refit in Odense, Denmark. The helicopter deck, originally above her bridge, was repositioned over the stern and a multibeam echosounder for survey work was installed. Her engines and gearboxes were overhauled and she was modified to allow the carriage of the ancillary vessels and vehicles (survey boats, all-terrain vehicles) used in support of the British Antarctic Survey.
From April 2011, she was chartered to the Royal Navy for three years as a temporary replacement for the ice patrol ship, HMS Endurance, and was renamed HMS Protector. The annual cost of the charter was £8.7m. In September 2013 the British Ministry of Defence purchased the ship outright from GC Rieber Shipping, for £51 million. In October 2013 the Ministry of Defence announced that from 1 April 2014 the ship's homeport would change from HMNB Portsmouth to HMNB Devonport, the location of the Hydrography and Meteorology Centre of Specialisation and where the Royal Navy's other survey ships are based.
She was commissioned into the Navy on 23 June 2011 as HMS Protector. The commissioning ceremony was held on the 50th anniversary of the date that the Antarctic Treaty came into force. During September 2011, Protector embarked on operational sea training in preparation for her first deployment in November.
In February 2012, after receiving a distress call from Comandante Ferraz Antarctic Station on King George Island in the South Shetland Islands, Protector sailed to provide assistance to the Brazilian research station after a large fire had broken out there. 23 of her sailors were put ashore with fire-fighting equipment to tackle the large blaze. Two of the researchers died in the incident.
During March and April 2012, the ship operated in the vicinity of Rothera Research Station. During a major visit, she delivered around 170 cubic metres of aviation fuel. At 67° 34′ S, this was the most southerly visit of her career up to that date, nearly 800 miles (1,300 km) from Cape Horn, the southernmost tip of the South America. The crew competed in a 'winter Olympics' with scientists from the British Antarctic Survey.
On the way to her second Antarctic deployment, in October 2012 Protector surveyed the wreck of the Dale-class oiler RFA Darkdale in James Bay, Saint Helena, as part of an assessment of its possible threat to the island's environment. On arriving in Antarctica in December, her designated Antarctic Treaty Observers supported an international team carrying out inspections of research stations to ensure compliance with the Antarctic Treaty.
The ship left for her third Antarctic deployment in October 2013. She revisited Rothera and then sailed across Marguerite Bay, reaching a latitude of 68° 12′ S, 850 miles (1,370 km) from Cape Horn.
Protector operates several small boats, including the survey motor boat James Caird IV, the ramped work boat Terra Nova and two Pacific 22 RIBs Nimrod and Aurora. She also embarks three BV206 all-terrain vehicles and a number of quad-bikes and trailers for activities on Antarctica, such as moving stores and equipment.
James Caird IV is a 10.5m, ice-capable survey motor boat built by Mustang Marine in Pembroke Dockyard, based on a design of existing British Antarctic Survey boats. It has a crew of five, plus up to five passengers. The boat was named by Alexandra Shackleton, the granddaughter of Antarctic explorer Ernest Shackleton, during the commissioning ceremony for Protector on 23 June 2011.
