Schilling Power Station was an oil-fired power station in the proximity of the nuclear power station at Stade . It went into operation in 1960, was extended in 1962 and 1964, and was shut down in the 1980s. Since it principally served Hamburg north for the electricity supply of Hamburg and fed its current into the transformer station, the first overhead line crossing of the Elbe was built at that time at Stade, the Elbe Crossing 1 . The buildings still exist today and are occasionally used for disaster control exercises.

You can help Misplaced Pages by expanding it . Heavy fuel oil Heavy fuel oil (HFO) is a category of fuel oils of a tar -like consistency. Also known as bunker fuel , or residual fuel oil , HFO is the result or remnant from the distillation and cracking process of petroleum . For this reason, HFO

84-401: A given use. As a result of the wide compositional spectrum, HFO is defined by processing, physical and final use characteristics. Being the final remnant of the cracking process, HFO also contains mixtures of the following compounds to various degrees: "paraffins, cycloparaffins, aromatics, olefins, and asphaltenes as well as molecules containing sulfur, oxygen, nitrogen and/or organometals". HFO

112-800: A specialized arm of the United Nations , adopted into force on 1 January 2017 the International Code for Ships Operating in Polar Waters or Polar Code. The requirements of the Polar Code are mandatory under both the International Convention for the Prevention of Pollution from Ships (MARPOL) and the International Convention for the Safety of Life at Sea (SOLAS) . The two broad categories covered by

140-476: Is characterized by a maximum density of 1010 kg/m at 15°C, and a maximum viscosity of 700 mm /s (cSt) at 50°C according to ISO 8217. Given HFO's elevated sulfur contamination (maximum of 5% by mass), the combustion reaction results in the formation of sulfur dioxide SO 2 . Since the middle of the 20th century, HFO has been used primarily by the shipping industry due to its low cost compared with all other fuel oils, being up to 30% less expensive, as well as

168-461: Is contaminated with several different compounds including aromatics , sulfur , and nitrogen , making emissions upon combustion more polluting compared to other fuel oils. HFO is predominantly used as a fuel source for marine vessel propulsion using marine diesel engines due to its relatively low cost compared to cleaner fuel sources such as distillates . The use and carriage of HFO on-board vessels presents several environmental concerns, namely

196-421: The radiative forcing of black carbon, combinations of ground and satellite observations suggest a global solar absorption of 0.9W·m , making it the second most important climate forcer after CO 2. Black carbon affects the climate system by: decreasing the snow/ice albedo through dark soot deposits and increasing snowmelt timing, reducing the planetary albedo through absorption of solar radiation reflected by

224-592: The Arctic as the greatest threat to the local marine environment. Being the remnant of the distillation and cracking processes, HFO is characterized by an elevated overall toxicity compared to all other fuels. Its viscosity prevents breakdown into the environment, a property exacerbated by the cold temperatures in the Arctic resulting in the formation of tar-lumps, and an increase in volume through emulsification. Its density, tendency to persist and emulsify can result in HFO polluting both

252-596: The Polar Code include safety and pollution prevention related to navigation in both Arctic and Antarctic polar waters. The carriage and use of HFO in the Arctic is discouraged by the Polar Code while being banned completely from the Antarctic under MARPOL Annex I regulation 43. The ban of HFO use and carriage in the Antarctic precedes the adoption of the Polar Code. At its 60th session (26 March 2010), The Marine Environmental Protection Committee (MEPC) adopted Resolution 189(60) which went into effect in 2011 and prohibits fuels of

280-473: The area. The two main environmental concerns for HFO in the Arctic are the risk of spill or accidental discharge and the emission of black carbon as a result of HFO consumption. Due to its very high viscosity and elevated density, HFO released into the environment is a greater threat to flora and fauna compared to distillate or other residual fuels. In 2009, the Arctic Council identified the spill of oil in

308-572: The ban is anticipated for 2021, with widespread implementation by 2023. The Clean Arctic Alliance was the first IMO delegate nonprofit organization to campaign against the use of HFO in Arctic waters. However, the phase-out and ban of HFO in the Arctic was formally proposed to MEPC by eight countries in 2018: Finland, Germany, Iceland, the Netherlands, New Zealand, Norway, Sweden and the United States. Although these member states continue to support

In 2013, Det Norske Veritas (Norway) and Germanischer Lloyd (Germany), two prominent organizations in

364-435: The cloud systems, earth surface and atmosphere, as well as directly decreasing cloud albedo with black carbon contamination of water and ice found therein. The greatest increase in Arctic surface temperature per unit of black carbon emissions results from the decrease in snow/ice albedo which makes Arctic specific black carbon release more detrimental than emissions elsewhere. The International Maritime Organization (IMO),

392-415: The emission of black carbon is the ship load size, with emission factors of black carbon increasing up to six times given low engine loads. Black carbon is the product of incomplete combustion and a component of soot and fine particulate matter (<2.5 μg). It has a short atmospheric lifetime of a few days to a week and is typically removed upon precipitation events. Although there has been debate concerning

420-503: The following characteristics: IMO's Marine Environmental Protection Committee (MEPC) tasked the Pollution Prevention Response Sub-Committee (PPR) to enact a ban on the use and carriage of heavy fuel in Arctic waters at its 72nd and 73rd sessions. This task is also accompanied by a requirement to properly define HFO taking into account its current definition under MARPOL Annex I regulation 43. The adoption of

448-518: The historically lax regulatory requirements for emissions of nitrogen oxides (NO x ) and sulfur dioxide (SO 2 ) by the IMO. For these two reasons, HFO is the single most widely used engine fuel oil on-board ships. Data available until 2007 for global consumption of HFO at the international marine sector reports total fuel oil usages of 200 million tonnes, with HFO consumption accounting for 174 million tonnes. Data available until 2011 for fuel oil sales to

DNV provides services for 13,175 vessels and mobile offshore units (MOUs), amounting to 265.4 million gross tonnes , which represents a global market share of 21%. 65% of the world's offshore pipelines are designed and installed to DNV's technical standards . Prior to

504-461: The initiative, several countries have been vocal about their resistance to an HFO ban on such a short time scale. The Russian Federation has expressed concern for impacts to the maritime shipping industry and trade given the relatively low cost of HFO. Russia instead suggested the development and implementation of mitigation measures for the use and carriage of HFO in Arctic waters. Canada and Marshall Islands have presented similar arguments, highlighting

532-683: The international marine shipping sector reports 207.5 million tonnes total fuel oil sales with HFO accounting for 177.9 million tonnes. Marine vessels can use a variety of different fuels for the purpose of propulsion, which are divided into two broad categories: residual oils or distillates. In contrast to HFOs, distillates are the petroleum products created through refining crude oil and include diesel, kerosene, naphtha and gas. Residual oils are often combined to various degrees with distillates to achieve desired properties for operational and/or environmental performance. Table 1 lists commonly used categories of marine fuel oil and mixtures; all mixtures including

560-417: The low sulfur marine fuel oil are still considered HFO. The use and carriage of HFO in the Arctic is a commonplace marine industry practice. In 2015, over 200 ships entered Arctic waters carrying a total of 1.1 million tonnes of fuel with 57% of fuel consumed during Arctic voyages being HFO. In the same year, trends in carriage of HFO were reported to be 830,000 tonnes, representing a significant growth from

588-775: The merger contract between DNV and GL to be signed on 12 September 2013. The independent Det Norske Veritas Foundation owned 63.5% of DNV GL shares and 36.5% of Mayfair Vermögensverwaltung until December 2017, when Mayfair sold its shares to the Det Norske Veritas Foundation. DNV GL changed its name to DNV on 1 March 2021. In September 2023, it was announced that DNV had acquired the US-headquartered SaaS company, ANB Systems.

DNV's history dates from 1864, when Det Norske Veritas was established in Norway to head

644-720: The potential impacts on Arctic communities (namely remote indigenous populations) and economies. To appease concerns and resistance, at its 6th session in February 2019, the PPR sub-committee working group developed a "draft methodology for analyzing impacts" of HFO to be finalized at PPR's 7th session in 2020. The purpose of the methodology being to evaluate the ban according to its economic and social impacts on Arctic indigenous communities and other local communities, to measure anticipated benefits to local ecosystems, and potentially consider other factors that could be positively or negatively affected by

672-497: The remnants or residual of petroleum sources once the hydrocarbons of higher quality are extracted via processes such as thermal and catalytic cracking . Thus, HFO is also commonly referred to as residual fuel oil. The chemical composition of HFO is highly variable due to the fact that HFO is often mixed or blended with cleaner fuels; blending streams can include carbon numbers from C 20 to greater than C 50 . HFOs are blended to achieve certain viscosity and flow characteristics for

700-492: The reported 400,000 tonnes in 2012. A report in 2017 by Norwegian Type Approval body Det Norske Veritas (DNV GL) calculated the total fuel use of HFO by mass in the Arctic to be over 75% with larger vessels being the main consumers. In light of increased area traffic and given that the Arctic is considered to be a sensitive ecological area with a higher response intensity to climate change, the environmental risks posed by HFO present concern for environmentalists and governments in

728-494: The risk of oil spill and the emission of toxic compounds and particulates including black carbon . The use of HFOs is banned as a fuel source for ships travelling in the Antarctic as part of the International Maritime Organization 's (IMO) International Code for Ships Operating in Polar Waters (Polar Code). For similar reasons, an HFO ban in Arctic waters is currently being considered. HFO consists of
