[OPENING MUSIC] NARRATOR: On March 18, 1967, the tanker, Torrey Canyon, ran aground on Seven Stones reef while bound for a Welsh oil terminal. She spilled her entire cargo of 120,000 tons of crude oil into the water, making it the largest oil pollution incident, as well as the largest shipwreck, at the time. This incident led to the creation of MARPOL, the International Convention for the Prevention of Pollution from Ships. Long before the adoption of MARPOL, it was recognized that even though accidental pollution made for bigger headlines, operational pollution was the greater threat. Millions of gallons of oil ended up in our oceans every year, most due to non-accidental sources such as routine maintenance, bilge and tank cleaning, illegal discharges and the transfer of oil between tanks. In this program, we will learn more about oily bilge water. What is an oily water separator and how does it work? International requirements regarding documentation and the oil record book, and how to use an oil record book. The lowest area on a ship is the bilge. A mixture of fuel, lubricant, chemicals and water drains into the engine room bilges in small quantities. This mixture is known as bilge water. Bilge water is an unavoidable product of shipboard operations. Where does bilge water go after it is collected? According to Annex One of MARPOL, oily bilge water cannot be discharged directly overboard. It either has to be stored for the duration of the voyage or pass through a device having these three components-- a bilge separator, an oil content monitor, and an automatic stopping device. Different ships require different arrangements. Vessels of 400 but less than 10,000 gross tons are only required to be fitted with oil filtering equipment. Vessels of 10,000 gross tons or more must be fitted with oil filtering equipment, an oil content monitoring system, an automatic stopping device, and an alarm system. When can you discharge builds water overboard? According to regulations, before you can legally pump bilge water over the side, all of the following conditions must be met. The ship must be en route. The oily mixture must be processed through approved oil filtering equipment. The oil content of the water must be less than 15 parts per million. And the oily mixture cannot originate from cargo pump room bilges or be mixed with oil cargo residues on tankers. An oily water separator is a device that does just that-- separates oil from water. It must also have the ability to separate contaminants, as well. Some of these contaminants include cleaning products, soot from combustion, rust, sewage and other things that may be harmful to the ocean. The goal of the oily water separator is to produce clean water for discharge. A typical oily water separator consists of three basic components-- the separator unit, the filter unit, and the oil content monitor and control unit. While every oily water separator may differ mechanically, based on its manufacturer, the science behind it is simple. Oil is less dense than water, and can be separated and removed by relying on the differences in specific gravity. The oily bilge water passes through multiple stages. First to remove solids, then a coalescer where oil and water are broken apart to allow it to be skimmed off. And then a final stage to remove any residual oil and sludges not eliminated in previous steps. All oily water separators must be fitted with an oil content monitor. This samples water going overboard to insure oil content is a less than 15 parts per million. If it passes this check, the monitor allows the water to be discharged. If the oil content is higher than 15 parts per million, the oil content monitor activates an alarm and the flow is stopped by an automatic shutoff valve. It is illegal to sail without a fully functioning oily water separator, or adequate spare parts on board. Because of this requirement, it is important to properly maintain your oily water separator. SHARISH PALSOLE: It's very important that people should know the equipment very well. So you should have an adequate, clear set of operating instructions on how to use the equipment, and also for that of the maintenance manuals. NARRATOR: The chief engineer is responsible for the oily water separator. However, crew members should become familiar with the operation and testing methods of this equipment. The maritime industry is committed to preventing the discharge of oil into the sea. On seagoing vessels, oil-related operations and discharges are required by law to be recorded in an oil record book. DAVID BIRD: So when mariners are making entries in ink in this document, it has a very official-- and it is a very official piece of record keeping. So I think that, in itself, can be a little bit intimidating. NARRATOR: The oil record book has two parts. Part One addresses machinery space operations, and is required for all vessels. Oil tankers of 150 gross tons and above, and every other ship of 400 gross tons and above must maintain Part One of the oil record book. Entries are completed on a tank-by-tank by basis each time any of the following operations can take place. Ballasting or cleaning of fuel oil tanks, discharge of dirty ballast or cleaning water from fuel oil tanks, collection and disposal of oil residues, overboard discharge for disposal of bilge water, condition of the oil filtering equipment, accidental or other exceptional discharges of oil, bunkering. Part Two of the oil record book addresses cargo and ballast operation, and is only required for oil tankers. Every oil tanker of 150 gross tons and above must have and maintain Part Two of the oil record book. The oil record book is self-explanatory. However, shipboard personnel have been known to make recording errors because they did not take the time to fully comprehend the instructions. Each book has an introductory section at the beginning which explains what needs to be documented, how entries must be made, who is required to sign, and when and where they need to sign. It is important to know what must be logged so entries can be completed with accuracy. There should be no empty lines between each recorded entry, and all entries must be recorded in ink. DAVID BIRD: If you don't know what's required upfront, you may not have the information that's needed in the book to record later. NARRATOR: Each entry must be made and signed by the officer or officers in charge of the operations. Each entry must be recorded as soon as possible after the operation is complete. Operations are coded with a letter to indicate what kind of operation is occurring. This is further specified with item numbers for individual operations. In this case, oil sludge is being collected. So the entry is coded with a C. It's item number is 11.1. The tank where the residue is stored is noted, and volume is always measured in cubic meters. Entries must be recorded in chronological order and entered in a specific day, month, and year format. Each completed page must be signed by the master of the ship. The oil record book must be readily available for inspections, and kept on board for a period of at least three years after the last entry is made. Maintaining an accurate record book is critical. Even the most minor violations can result in large fines. The United States alone has imposed fines totaling $52 million to date. Both the company and the officer responsible can be subject to civil and criminal prosecution and imprisonment for deliberate falsification of documents. SHARISH PALSOLE: There's nothing to be gained by hiding or falsifying records because you can get into a lot of trouble. Not only you as a person, as an individual, but you could cause the company a lot of trouble by withholding information, so to speak. NARRATOR: The International Maritime Organization understands the human component involved in keeping accurate data. There are no penalties for mistakes. DAVID BIRD: Certainly, you can go back and correct mistakes. That's not an issue. The Coast Guard isn't out to punish people for making honest mistakes in record book entries. NARRATOR: The IMO and other agencies have published specific guidelines for correcting mistakes. If an incorrect entry is made in the record book, simply strike through the incorrect entry with a single line in such a way that the wrong entry is still legible. Sign and date the wrong entry. And enter the correct information. In this program, we learned about oily bilge water. What is an Oily Water Separator and how does it work? International requirements regarding documentation and the oil record book, and how to use an oil record book. the documentation of oily water discharges, Each crew member should be doing their part at all times to ensure their ship is in compliance with port, state, and international regulations regarding oil pollution and illegal discharges. Maintaining clean and safe seas depends on it.
