Product/cargo not conforming to specifications – Refined products or other goods that do not meet normal quality requirements and therefore require special handling and restriction to ensure the separation of products/cargoes in accordance with specifications. 1 Crude oil in any form, including crude oil, heating oil, sludge, petroleum waste and refined products (with the exception of petrochemicals subject to the provisions of Annex II to this Convention) and, without limiting the generality of the foregoing, including substances listed in Annex I to this Annex. Clean Products: Refers to light and refined petroleum products such as kerosene, gasoline, diesel and naphtha. API Gravity: Any scale that expresses the gravity or density of liquid petroleum products. The measurement scale is calibrated to the API degree. The higher the severity of the API, the easier the connection. Light crude oils typically exceed 38 degrees API and heavy crude oils are commonly referred to as all crude oils with an API gravity of 22 degrees or less. Draft – The distance between the ship`s waterline and the ship`s top point, usually the top of a radar mast or tower. If a ship has to pass through areas where there may be obstacles (bridges, power lines, cranes, loading arms, etc.), it is important to know how high its draught (draught) will be at the time of transit. The draught of a ship depends on the draught of the ship and its fairing. Chemical tankers: As defined by Danish Ship Finance – a tanker with zinc, epoxy, Marineline coating or stainless steel (IMO I-II) tanks.
Cubic Limitation – Reach the capacity of the cargo tank before the ship sinks into its loading line. This is usually caused by loading light crude oil (crude oil with a high API) or clean products. Gross Standard Volume (GSV) – Total volume of all petroleum fluids, sediments and water, excluding open water, corrected by the appropriate volume correction factor (Ctl) for observed temperature and API gravity, relative density or density at a standard temperature such as 60°F or 15°C and also corrected by the applicable pressure correction factor (Cpl) and counter-factor. STOC MARCIA can transport dirty products such as tall oil and coal tar, but also petroleum and chemical products. The main engine Wärtsilä 6L32 has a power of 3000kW. Heating coils – coils located at the bottom of cargo tanks through which steam circulates to heat the cargo. The heat lowers the viscosity of the cargo and facilitates the pumping of the cargo at the port of exit. Containers in clean operation usually do not have or do not require heating coils, because the viscosity of clean products (with the exception of some lubricating oils) is high enough to allow easy pumping at atmospheric temperatures. Clean service – Transport by tanker truck of products lighter than residual fuels, e.B distillates, including heating distillate oil No. 2. The medium-sized tanker has a capacity of 35,000 to 100,000 DWT (about 280,000 to 800,000 BPD).
Typically, people under 60,000 DWT can carry “clean” loads, while those over 80,000 DWT can carry almost exclusively crude oil or other “dirty” cargoes. The military advantages of medium-sized tankers are that they are more readily available than practical tankers and are capable of delivering large quantities of pol. Their military disadvantage is that it is difficult and time-consuming (1-2 weeks) to clean the tanks and pipelines of tankers that have transported crude oil or other “dirty” cargoes, so that they can be used for the transport of refined POL products. Medium-sized tankers cover a wide range of vessel types. Ships of this size class are capable of carrying almost all types of petroleum products. The smallest group will usually carry gasoline, kerosene, chemicals and heating oils. The larger size of the group will carry heating oils and heavier crude oils. High-temperature oil tankers are carriers of products for the transport of molten sulphur, bitumen, dirty petroleum products, coal tar, pitch and coal tar. They maintain a charging temperature between 160 °C and 240 °C, which imposes very high requirements in terms of heating, insulation of tanks and pipes as well as associated valves and pumps. See also the high-temperature tanker BITFLOWER. Aframax Carrier – A medium-sized tanker with a deadweight of about 80,000 to 120,000 tons. Aframaxes can typically carry between 500,000 and 800,000 barrels of crude oil and are also used in cooking.
A coated Aframax that is active in the trade of refined petroleum products can be described as LR2. Petroleum Classification – the “A-C” classes of petroleum are considered flammable and have a flash point of 80°F or less. Examples of these classes range from very light nimphars (Class A) to most crude oils (Class C). Class D loads such as kerosene and heavy crudes are considered flammable and have a flash point above 80°F but below 150°F. Class E loads are the heaviest fuel oils and lubricating oils and have a flash point greater than 150°F. Classification Society – The professional associations that classify and certify the strength and airworthiness of shipbuilding. The class and certification issued to each ship may be required for insurance purposes. The American Bureau of Shipping (ABS) and Lloyds Register of Shipping are now two of the world`s best-known classification societies. – Gas conveyors are intended for the transport of various liquefied gases used for energy purposes (petroleum gas, natural gas), in the chemical industry (ethylene, vinyl chloride, propylene, etc.) or as raw materials for the production of agricultural fertilizers (ammonia). Product tanker: Petroleum tanker with coated tanks for the transport of refined petroleum products.
Lump sum – The alternative to global fixing for cash charter parties is to set an agreed lump sum for a particular trip. Flat-rate schemes are more common in commodity trading than in crude oil markets. We have expertise in the transportation of crude oil and petroleum products and have advised in many different areas, including: Slops – A mixture of oil and water usually produced during tank washes. Barrel: Volumetric unit measurement for crude oil and petroleum products equivalent to 42 U.S. .
