Emergency tow vessel An emergency tow vessel , also called emergency towing vessel , ( ETV ) is a multi purpose boat used by state authorities to tow disabled vessels on high seas in order to prevent dangers to man and environment . The disabled vessel is either towed to a safe haven or kept in place against wind and current until commercial assistance by tug boats has arrived on site or until it has been repaired to the extent of being able to manoeuvre on its own . The need for ETVs as a preventive measure has arisen since the number of available commercial salvage tug s was reduced while potential dangers from individual vessels have increased . E . g . Spain has fourteen , Turkey has eleven , Germany operates eight , Norway has seven , France has five , Sweden three and the Netherlands , Poland , South Africa , Iceland and Finland each have one official emergency tug boat . Australia also operates emergency response vessels . The United Kingdom ' s four strong ETV fleet was to be disbanded in September 2011 due to budget cuts but the two vessels operating in Scottish waters received an extension of contract until the end of 2011 . External requirements . Distressed vessels that request the service of towing vessels have means to make towing as safe as possible . Oil tankers have emergency towing equipment fixed at the forward and aft part of the vessel that will allow to connect the towing line . The connection of these apparatuses to the vessel ' s hull is reinforced according with class requirements . Bulk carrier s and general cargo vessels are not required to have a specialized emergency towing arrangement . Depending on the vessel ' s type and keel laid date , in accordance with the MSC256 ( 84 ) standard they must have on board an emergency towing procedure manual . This ship - specific manual describes procedures that will allow the vessel to be towed using its own equipment . The procedure should make use of the standard mooring equipment like mooring ropes , bits , rollers and Panama chock . National ETV fleets . Algeria . In 2010 Algeria has ordered three tug boats of the " Bourbon " class which is already in use in the French harbours of Brest and Cherbourg . The ships have been built by STX OSV in Norway and STX Tulcea in Romania . A first vessel " El Moundjid " was ready for delivery in December 2011 , the two others are scheduled for delivery in June and September 2012 . With a bollard pull of 200 tons and a speed of , the Algerian ETVs are an improved version of the French " Bourbon " class . They will be based in Oran and Skikda . By acquiring these three ships , Algeria has become the leading Mediterranean nation in terms of marine salvage . Finland . The Ministry of the Environment operates the " Louhi " . The vessel can be used for emergency towing , fire - fighting , icebreaking , mine - laying and for combat oil / chemical spills , and other rescue operations . The vessel has a bollard pull of 60 t . YAG " Louhi " is based at the Port of Upinniemi approximately 40 km west of Helsinki in the Archipelago Sea . France . For assistance and salvage , 5 ocean - going tugs and their crews are ready to respond around - the - clock The tugs are chartered by the French government and manned by a crew of merchant marine seamen . France also shares funding of the Dover based British ETV . Germany . The German concept of emergency towing prescribes a maximum response time of two hours for any incident in German coastal waters . This requires three ETVs in the North Sea and five in the Baltic Sea despite a considerably smaller area to cover there . Equipment and performance of the vessels have been adapted to the size of the vessels in the respective areas of operation and include the ability to operate in shallow waters . Moreover it is mandatory to have one vessel with 200 t of bollard pull and 100 t each in the North Sea and Baltic respectively . Both ship types are also required to be able to operate under hazardous conditions such as explosive areas and gas leaks . Four out of the eight German ETVs are multi purpose vessels owned by the Federal Water and Shipping Administration while another four have been chartered from tug companies . Since 2001 a cooperation agreement with the Netherlands comprises the Dutch ETV and the German " Nordic " ( successor to ETV " Oceanic " ) . Current fleet : Iceland . Iceland has the ICGV " Þór " . With a bollard pull of about 110 tonnes it has been specified so , that in case of emergency the new Icelandic Coast Guard vessel will be able to tow stricken tankers of up to about 200 , 000 dwt . Netherlands . The Netherlands Coastguard operates one ETV on charter . As of June 2010 , the anchor handling tug " Ievoli Black " , bollard pull of 120 t , has been contracted . She is based in Den Helder and manned by a crew of Svitzer Wijsmuller . The former ETV " Waker " was damaged by a fire and scrapped . Norway . The Norwegian Coast Guard owns three Barentshav class OPV multi - purpose vessels and operates another multi - purpose vessel named NoCGV " Harstad " on charter . Their main purpose is the prevention of pollution by oil tankers along the Norwegian coastline . Therefore the ships can also used be used in the ETV role with a bollard pull exceeding 100 tonnes . Norway also charters the following tugs : Poland . The Polish Ministry of Transport has organised a marine pollution - combatting service in Poland . It operates one ETV on charter , the tug " Kapitan Poinc " , bollard pull of 74 t . South Africa . The tug " Smit Amandla " ( bollard pull of 181 t ) has been contracted for emergency towing . She is based in the port of Cape Town . Spain . The Sociedad de Salvamento y Seguridad Marítima has a total of 14 multi - purpose vessels for search and rescue and pollution prevention duties . Sweden . The Swedish Coast Guard operates three EVT ' s of the same type . Built by Damen , these multifunctional patrol and emergency response vessels have a bollard pull of 100 tons . They were taken into operation during 2009 and 2010 and are operated by the Swedish Coast Guard . Turkey . The Turkish Directorate General of Coastal Safety operates 11 ETVs along with numerous SAR , oil spill response and fire fighting vessels at Bosphorus and Dardanelles , where the organization has a " de jure " monopoly for marine salvage along with the Sea of Marmara . Some of these ETVs also serve as escort tugs for vessels passing through Bosphorus and Dardanelles , which make up the Turkish Straits System , one of the busiest and dangerous seaways all around the world . The organisation also deals with navigational aids all around Turkey , SAR , pilotage at both straits and some other Turkish ports and most importantly Turkish Straits Vessel Traffic Systems . United Kingdom . The UK ' s ETV vessels were chartered by the Maritime and Coastguard Agency ( MCA ) for use in pollution control or towing vessels that were in difficulty . The vessels are a combination of tugboat , anchor handler , fireboat and buoy tender . As of 2010 , four ETVs , " Anglian Prince " , " Anglian Princess " , " Anglian Sovereign " and " Anglian Monarch " , were based in strategic locations around the UK , with two covering the south coast of England , at Falmouth in Cornwall and Dover in Kent , and two in Scottish waters , at Stornoway the Western Isles ( the Outer Hebrides ) , and Lerwick in the Northern Isles ( Shetland and Orkney ) . The four strong ETV fleet was intended to be operational 24 hours a day 365 days a year and maintained at 30 minutes readiness to sail , with one tug is allocated to each of the four operating areas on a rotational basis , worked around maintenance schedules . The Dover station was funded jointly with French maritime authorities . A fifth tug , the " Anglian Earl " , was an anchorhandling and salvage tug regularly used on commercial work , but also fitted the ETV criteria , and acted as cover for any of the four ETV stations as and when required . In 2010 , the Government announced as part of the Department for Transport ' s share of cuts in the Comprehensive Spending Review , that the ETV fleet would be no longer be funded by the MCA from September 2011 , saving £32 . 5m over the Spending Review period . The Department stated that " state provision of ETVs does not represent a correct use of taxpayers money and that ship salvage should be a commercial matter between a ship ' s operator and the salvor " . On 30 September 2011 it was however announced that the two ETVs operating in the Minch and the Shetland Islands received a moratorium of three months with an interim funding by the United Kingdom ' s government .
