Port Reception Facilities
Port reception facilities are a place that international shipping ports must provide to collect residues, oily mixtures, and garbage generated from an ocean-going vessel. contaminants generated by ships cannot be discharged directly to the ocean. According to MARPOL 73/78 they must be collected by the Port reception facilities all around the world. The Port reception facility must be able to receive dirty oil and other contaminants, and also provide quick and efficient services. In March 2006, MEPC 54 emphasized the value of reception facilities that would exceed expectations in the implementation of MARPOL 73/78, MARPOL, and introduced a policy of "zero tolerance of illegal discharges from ships" that could only be enforced when there were adequate reception facilities in ports. Therefore, the Committee urged all Parties to MARPOL 73/78, MARPOL, particularly port States, to fulfill their treaty obligations to provide reception facilities for wastes generated during the normal opera ...

Ports
Ports collections (or ports trees, or just ports) are the sets of makefiles and Patch (Unix), patches provided by the BSD-based operating systems, FreeBSD, NetBSD, and OpenBSD, as a simple method of installing software or creating binary packages. They are usually the base of a package management system, with ports handling package creation and additional tools managing package removal, upgrade, and other tasks. In addition to the BSDs, a few Linux distributions have implemented similar infrastructure, including Gentoo Linux, Gentoo's Portage (software), Portage, Arch Linux, Arch's Arch Build System, Arch Build System (ABS), CRUX's Ports and Void Linux's Templates. The main advantage of the ports system when compared with a binary distribution model is that the installation can be tuned and optimized according to available resources. For example, the system administrator can easily install a 32 bit version of a package if the 64 bit version is not available or is not optimized for t ...

Oil Record Book
All cargo vessels where MARPOL Convention is applicable must have an oil record book in which the officer responsible will record all oil or sludge transfers and discharges within the vessel. This is necessary for authorities to be able to monitor if a vessel's crew has properly disposed of their oil discharges at sea. Each oil tanker of 150 gross tons and above, ship of 400 gross tons and above other than an oil tanker, and crewed fixed or floating drilling rig or other platform shall maintain an Oil Record Book Part I (Machinery Space Operations). An oil tanker of 150 gross tons and above or a non-oil tanker that carries 200 cubic meters or more of oil in bulk, shall also maintain an Oil Record Book Part II (Cargo/Ballast Operation). Oil record book coding In every entry the chief engineer must record tank number, location, type of oil, description of operation, and quantity. For every operation a combined numerical and letter coding is applied. MEPC.187(59) describes the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Waste Collection
Waste collection is a part of the process of waste management. It is the transfer of solid waste from the point of use and disposal to the point of treatment or landfill. Waste collection also includes the curbside collection of recyclable materials that technically are not waste, as part of a municipal landfill diversion program. Household waste Household waste in economically developed countries will generally be left in waste containers or recycling bins prior to collection by a waste collector using a waste collection vehicle. Waste collection barges are used in some towns, for example in Venice, Italy. However, in many developing countries, such as Mexico and Egypt, waste left in bins or bags at the side of the road will not be removed unless residents interact with the waste collectors. Mexico City residents must haul their trash to a waste collection vehicle which makes frequent stops around each neighborhood. The waste collectors will indicate their readiness ...

Oil Discharge Monitoring Equipment
Oil discharge monitoring equipment (ODME) is based on a measurement of oil content in the ballast and slop water, to measure conformance with regulations. The apparatus is equipped with a GPS, data recording functionality, an oil content meter and a flow meter. By use of data interpretation, a computing unit will be able to allow the discharge to continue or it will stop it using a valve outside the deck. __TOC__ Operating principle A sample point on the discharge line allows for the analyzer to determine the oil content of the ballast now and slop water in PPM. The analyzer is self-maintaining by periodical cleansings with fresh water, and therefore requires a minimum of active maintenance from the crew. The results of the analyzer are sent to a computer, which determines whether the oil content values are to result in overboard discharge or not. The valves that direct the ballast water either over board or to slop tank are controlled by the integrated computer, and a GPS si ...

Magic Pipe
A magic pipe is a surreptitious change to a ship's oily water separator (OWS), or other waste-handing equipment, which allows waste liquids to be discharged in contravention of maritime pollution regulations. Such equipment alterations may allow hundreds of thousands of gallons of contaminated water to be discharged untreated, causing extensive pollution of marine waters. Manipulation techniques The pipe may be improvised, aboard ship, from available hoses and pumps, to discharge untreated waste water directly into the sea. As ships are required to keep records of waste and its treatment, magic pipe cases often involve falsification of these records. The pipe is ironically called "magic" because it bypasses the ship's oily water separator and goes directly overboard. Hence, it can make untreated bilge water "magically disappear". Often the pipe can be easily disconnected and stored away into a different location aboard the ship so state and regulatory officers can not detect it ...

Oily Water Separator (marine)
An oily water separator (OWS) (marine) is a piece of equipment specific to the shipping or marine industry. It is used to separate oil and water mixtures into their separate components. This page refers exclusively to oily water separators aboard marine vessels. They are found on board ships where they are used to separate oil from oily waste water such as bilge water before the waste water is discharged into the environment. These discharges of waste water must comply with the requirements laid out in MARPOL 73/78, Marpol 73/78. Bilge water is a nearly-unavoidable byproduct of shipboard operations. Oil leaks from running machinery such as diesel generators, air compressors, and the main propulsion engine. Modern OWSs have alarms and automatic closure devices which are activated when the oil storage content of the waste water exceeds a certain limit(15ppm : 15 cm3 of oil in 1m3 of water). Purpose The primary purpose of a shipboard oily water separator (OWS) is to separate oil an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oil Content Meter
An oil content meter (OCM) is an integral part of all oily water separator (OWS) systems. Oil content meters are also sometimes referred to as oil content monitors, bilge alarms, or bilge monitors. OCM technology The OCM continuously monitors how much oil is in the water that is pumped out the discharge line of the OWS system. The OCM will not allow the oil concentration of the exiting water to be above the Marpol standard of 15 ppm. This standard was first adopted in 1977 with Resolution A.393(X) which was published by IMO. These standards were updated various but the most current resolution is MEPC 108(49). The oil content meter will sound an alarm if the liquid leaving the system has an unsatisfactory amount of oil in the mixture. If it is still above that standard, then the bilge water will be reentered into the system until it meets the required criteria. The OCM uses light beams to determine how oily the water in the system is. The system will then gauge the oil conc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Contaminant
Contamination is the presence of a constituent, impurity, or some other undesirable element that renders something unsuitable, unfit or harmful for the physical body, natural environment, wiktionary:Workplace, workplace, etc. Types of contamination Within the sciences, the word "contamination" can take on a variety of subtle differences in meaning, whether the contaminant is a solid or a liquid, as well as the variance of environment the contaminant is found to be in. A contaminant may even be more abstract, as in the case of an unwanted energy source that may interfere with a process. The following represent examples of different types of contamination based on these and other variances. Chemical contamination In chemistry, the term "contamination" usually describes a single constituent, but in specialized fields the term can also mean chemical mixtures, even up to the level of cellular materials. All chemicals contain some level of impurity. Contamination may be recognized or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Municipal Solid Waste
Municipal solid waste (MSW), commonly known as trash or garbage in the American English, United States and rubbish in British English, Britain, is a List of waste types, waste type consisting of everyday items that are discarded by the public. "Garbage" can also refer specifically to food waste, as in a garbage disposal; the two are sometimes collected separately. In the European Union, the semantic definition is 'mixed municipal waste,' given waste code 20 03 01 in the European Waste Catalog. Although the waste may originate from a number of sources that has nothing to do with a municipality, the traditional role of municipalities in collecting and managing these kinds of waste have produced the particular etymology 'municipal.' Composition The composition of municipal solid waste varies greatly from municipality to municipality, and it changes significantly with time. In municipalities which have a well-developed waste recycling system, the waste stream mainly consists of int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sewage Sludge
Sewage sludge is the residual, semi-solid material that is produced as a by-product during sewage treatment of industrial or municipal wastewater. The term "septage" also refers to sludge from simple wastewater treatment but is connected to simple on-site sanitation systems, such as septic tanks. After treatment, and dependent upon the quality of sludge produced (for example with regards to heavy metal content), sewage sludge is most commonly either disposed of in landfills, dumped in the ocean or applied to land for its fertilizing properties, as pioneered by the product Milorganite. The term " Biosolids" is often used as an alternative to the term sewage sludge in the United States, particularly in conjunction with reuse of sewage sludge as fertilizer after sewage sludge treatment. Biosolids can be defined as organic wastewater solids that can be reused after stabilization processes such as anaerobic digestion and composting. Opponents of sewage sludge reuse reject this t ...
