Cargo Vessel Size Classifications

Cargo shipping is a low-margin business model that requires vessels to be fully loaded in order to sustain profitable operations. When a ship is in the design phase its almost always structured in a specific classification of naval architecture and built to serve a specific route or purpose. Measuring Terminology Vessels built to pass through specific bottlenecks while carrying the maximum amount of cargo are termed â€Å"max.† (For example, freighters designed to pass through the Panama Canal are called Panamax.) This means the ship will fit into a minimum bounding box that matches the dimensions of the smallest locks in the canal. Bounding boxes are measured three-dimensionally. In addition to maximum length and width, the measurements include areas underwater and above the deck. In maritime-specific cases, the dimensions of a bounding box have some different but still familiar names: Draft is the measurement from the surface of the water to the bottom.The beam is the width of a vessel at its widest point.Length is measured as the overall length of a ship, however, in some cases, maximum dimensions might take into consideration the length at the waterline which can differ significantly from length overall (LOA) due to the deadrise of the hull.Air Draft is the measure of the maximum height above the waterline of any structure on the ship.Gross Tonnage (GT) and Dead Weight Tonnage (DWT), while thought by many to be measures of weight, are more accurately described as measures of the volume of a vessel’s hull. Weight only factors in when an equivalent weight of water displaced by the hull must also be expressed. Ship Size Classification Definitions Most of these definitions pertain to cargo vessels but they can be applied to any kind of ship, including military and cruise ships. Aframax—This classification almost always refers to oil tankers, although its occasionally applied to other bulk commodities. These vessels serve oil-producing areas with limited port resources or where man-made canals lead to terminals that load raw petroleum products. The size limitations in this class are few. The main restriction is the beam of the vessel, which in this case cannot exceed 32.3 Meters or 106 feet. The tonnage of an Aframax is approximately 120,000 DWT. Capesize—This is an example in which the naming scheme varies but the sizing concept is the same. Capesize vessels are large bulk carriers and tankers that get their name from the route they must take to bypass the Suez Canal. Depending on the ships final destination, this route takes them past the Cape of Good Hope in Africa or Cape Horn of South America. A Capesize ship is limited by the depth of the Suez Canal which is currently 62 feet or about 19 meters. The displacement of these vessels can range from 150,000 to as much as 400,000 DWT. The soft geology of the region has allowed the canal to be dredged to a greater depth since it was first built, and its possible the canal will be dredged again in the future. As a result, the maximum draft limit of classification may change as well. Chinamax—The Chinamax classification is determined by the size of port facilities rather than by physical obstructions or limitations associated with a specific waterway. As a result, the term is not only applied to ships, but also to port facilities themselves. Ports that can accommodate these very large vessels are referred to as Chinamax compatible, whether or not theyre anywhere near China. They must meet the draft requirements of dry bulk carriers in the 350,000 to 400,000 DWT range while not exceeding 24 meters or 79 feet of draft, 65 meters or 213 feet of beam, and 360 meters or 1,180 feet of overall length. Malaccamax—For naval architects designing this class of ship, the main restriction is the draft of the vessel. The Strait of Malacca has a depth of 25 meters or 82 feet so ships of this class must not exceed that depth at the lowest point of the tidal cycle. Vessels serving this route can gain capacity in the design phase by increasing beam and length at the waterline in order to carry a greater capacity in a limited draft situation. Panamax—Panamax was once the most commonly recognized ship classification due to its derivation from the world-famous Panama Canal. Panamax size limitations are 294 meters or 965 feet in length, 32 meters or 106 feet of beam, 12 meters or 39.5 feet of draft, and 58 meters or 190 feet of air draft so vessels can pass under the Bridge of the Americas. The Panama Canal opened in 1914. By 1930, there were already plans to enlarge the locks to allow the passage of larger vessels. In 2014, construction for a third larger set of locks that went into operations in 2016, ushered in a new class of vessels called New Panamax. New (Neo) Panamax—New Panamax has size limitations of 366 meters or 1,200 feet in overall length, 49 meters or about 160 feet of beam, and a draft of 15 meters or 50 feet. The air draft remains the same to accommodate passage under the Bridge of the Americas, which is now the main limiting factor for large vessels passing through the canal. Seawaymax—This class of vessels is designed to achieve the maximum size for passage through the Saint Lawrence Seaway inbound or outbound from the Great Lakes system. The locks of the Seaway are the limiting factor in this classification. The Saint Lawrence can accommodate ships no larger than 225.5 meters or 740 feet of overall length, about 24 meters or 78 feet of beam, about eight meters or 26 feet of draft, and an air draft of 35.5 meters or 116 feet above the water. Larger vessels that operate on the Great Lakes are unable to reach the sea due to a bottleneck at the locks. Suezmax—The dimensions of the Suez Canal are the limiting factor for the size of ships in this class. Since there are no locks along the one-hundred-plus miles of the canal, the only limitations are draft and air draft. The canal has a useful draft of 19 meters or 62 feet. Vessels are limited by the height of the Suez Canal Bridge that has a clearance of 68 meters or 223 feet. Supermax/Handymax—Once again this class of ships is not restricted by a specific set of locks or bridges, but instead, it refers to cargo capacity and the ability to use ports. Ports are often designated to be Supermax or Handymax compatible. As the name implies, Supermax is the largest of the vessel classifications, with a size of around 50,000 to 60,000 DWT and can be as long as 200 meters or 656 feet. Handymax vessels are slightly smaller and have a displacement of 40,000 to 50,000 DWT. Such ships are usually at least 150 meters or 492 feet. Source Maritime Connector Website

High Art And Low Art Essay - 1799 Words

The Merriam-Webster dictionary defines art as something that is created with imagination and skill and that is beautiful or that expresses important ideas or feelings: works created by artists: paintings, sculptures, etc., that are created to be beautiful or to express important ideas or feelings. The main thing I take from this the definition, which is that it is all subjective. While one person may think a painting or a stage play is beautiful someone may not see the same thing or come close to having the same opinion. With that being said I think that finding a concrete answer to give to a class every year till the end of time will never happen. However, I’ll show you my opinion within this essay as well. Now the difference between high art and low art is based on multiple things. Matt Plescher, who’s an artist and author of High and Low Art on the website The Rapidian, thinks high art is supposed to have some type of â€Å"aesthetic contemplation† while low art is just â€Å"functional† within itself. Another quality that high art is supposed to have is typically a â€Å"limited audience† and is â€Å"unique, complex, sing or limited in production.† Low art is meant to be â€Å"formulaic, simple, easily accessed, and/or massed produced.† Which fits what people typically think when it comes to having to define high art and low art, including what we have discussed in class about the subject matter.

Another tone of the persona is serious. The overall theme, being the demanding of freedom, gives off a serious tone because the subject of racism and segregation in itself is a serious topics and was a problem that had to be faced by the African Americans during the 1960s when the poem was written. This subject matter has been and currently is being taken seriously. The persona also portrays a secretive tone. This is seen in verses four through nine of the poem, Answering the usual questions that come to white mind hich seeks demurely to probe in polite way the why and wherewithal of darkness U. S. A. In this quote the reader observes that in a secretive manner, the white people are trying to sound polite and kind while questioning the black race and their success when in reality they are doing it out of arrogance and unacceptance. Darkness U. S. A symbolizes the corruptness of the white peoples thoughts and conversation.

My Personal Narrative †English Essay

My Personal Narrative – English Essay Free Online Research Papers My Personal Narrative English Essay I opened the door and walked out of the Deseret Towers W-Hall lobby, where I was immediately welcomed by a powerful rush of heat. I suppose I had been told enough times about the scorching temperatures that day, but I must have conveniently forgotten to stick that fact in my realm of conscious thought. Oh, well. My cousin Jon apparently didn’t share the same apathy. â€Å"Why the crap is it so hot out here?† I smiled, then chuckled inwardly. Stopping to check my bearings just four or five paces from the door, I gazed west, then east. I then pulled a folded, miniature yellow campus map out of my pocket and stared intently at it. Not looking up, I muttered to Jon, â€Å"What and where is the M-O-R-C?† â€Å"I don’t know. Is that where we’re supposed to be?† he asked. â€Å"Yeah,† I began, and then, discovering the black square on the map containing the abbreviation MORC, I announced, â€Å"Oh. It’s right over there. Ok- that’s cool. Let’s go.† After refolding my map I spun left on my heel and we began walking east to the Morris Center. During my eighth grade year, my mother signed me up for a program known as Summer Scholars Academy. Apparently, she was impressed with my excellent grades at the end of my middle school career and wished to nurture my academic skills by sending me off to a learning camp. Originally reluctant, I agreed to give this â€Å"Academy† a try when I discovered my favorite cousin and good friend Jon was also attending. The program was to be held at BYU, â€Å"and so,† my mother told me, â€Å"almost all of the kids attending are going to be members of the Church. It’ll be kind of new for you.† New for me? I lived in Boise, Idaho, for goodness sake. Still, I supposed, half the kids in my grade weren’t members. I guess â€Å"almost all† would be a nice improvement. We walked into the Morris Center and gave our blue temp cards to the hostesses at the food center entrance. After swiping mine, she smiled and gave it back. Initially straight-faced, I quickly managed a reflexive smile and continued into the cafeteria. I didn’t think of it much then, but that smile was my first glimpse of a new transcendental society with which I was yet to become acquainted. My mom and her sister sent in our registration papers for Summer Scholars Academy in March. Apparently, they wanted to get them in quickly so we would have top positions in the entrance order- I don’t know. The deadline was June 15th, so they may have just had some sort of personal philosophy against procrastination. The entrance papers required academic records, test scores, teacher recommendations- the whole works. Jon and I were both students of merit, and we received word of acceptance into the program in April. Essentially, we had four months to prepare for our first time sleeping without our family far away from home for longer than a couple nights. It was definitely more than a couple nights, too- nine, to be precise. Still, â€Å"Scholar’s Academy?† It wasn’t quite the top socially accepted camp title among juveniles. Jon and I both refrained from referring to the program as anything other than â€Å"the thing this summer,† or â€Å"that ca mp we’re going to,† to avoid vain repetition and constant reminder of the fact we were going to leave our homes to become more enlightened nerds. That and similar phrases popped into my mind as we stood in the cafeteria line listening to other â€Å"scholars’† conversations. I admit that I was skeptical about this camp- given its title, I conjured up a theory that everyone else there would lack either a personality or social skills or both. I didn’t consider myself to be a social butterfly or Don Juan or anything, but I did command a fair amount of social courage. Dwelling on that thought, I then determined to prove my theory and introduce myself to the Summer Scholar behind me in line. I turned, opened my mouth, and my theorem was shattered as that short brown-haired girl looked in my eye and said with confidence, â€Å"Hi. I’m Wendy. What’s your name?† I raised my eyes in surprise. â€Å"I†¦ I’m Howard. And, this is Jon,† I said, pointing to my cousin. â€Å"Hi, Jon,† she said, cheerfully. He returned the greeting. â€Å"Where’re you from?† she continued. â€Å"We’re both from Boise,† I answered. â€Å"Cool. I’m from Rock Springs, Wyoming.† And so, the camp began on that note. What I began witnessing over the next nine days was a society that produced a momentous transformation in my perspective on people. Before I came to Summer Scholar’s Academy, I was quite cynical of teenage society. How could one not be? I had just finished middle school- the embodiment of social competition. Middle school society is really the first worldly microcosm. Children come out of elementary school with an understanding of friendship, and quickly find that they now need to classify and quantify their friends so they may gain a position on a social scale. Such a society classes people and covets popularity, along with embracing an established dogma of â€Å"love not thy brother below thee.† It is testing to any child, and it takes a great amount of virtue to break out of such conformity, something that I never fully accomplished. I was a cheerful kid in elementary school, but I lost my smile after fifth grade. One can only image my surprise, then, when I walked out of the Morris Center that day, and passing through the first set of double doors, discovered that another male member of the camp was holding the second set open for Jon and I. â€Å"Thanks†¦dude,† I began. What could I say? This had never happened to me before; the only people that ever held the door open for me were my parents, and even that stopped when I was about six. Such random acts of kindness flourished throughout the next eight days. It soon became apparent that greeting people you didn’t know and holding the door open for anyone behind you were established doctrines. Additionally, the more specific principle of â€Å"open doors for all females,† a chivalrous tradition that I was sure had all but disappeared from this dispensation (except from the mind of my mother), was firmly implanted in my personal philosophy. One of the cardinal sins in middle school is associating with an underclassman. If you are in eighth grade, you do not talk to a sixth grader, unless you are telling them to get out of your way or something with a similar topic. Within three days of Summer Scholars Academy, Jon and I were hanging out with seniors, juniors, sophomores, and a few freshmen. It was incredible; they were not just being nice- they were genuine friends, people with whom it was possible to keep in contact with regardless of great lengths of distance and time. During the camp, we participated in a lot of academic activities, like a college bowl and various scholastic classes. We attended spiritual events- devotionals and a testimony meeting, along with several entertaining activities such as a water park, a barbecue, and three dances. In retrospect, I realize I learned a lot, built my testimony, and had a lot of fun. Yet, the personal results of the official schedule of the camp did not add anything. The activities were well planned, but they only sought to augment what I already possessed- for me, they did not add anything new. The aspect of the camp which changed my perspective forever was the people there- the transcendental society of Summer Scholars Academy. Almost all the people there, although all different in personality, lived by one guiding precept: â€Å"it’s cool to be nice.† This shaped and elevated the society; it made it higher than the one in which we now live. Admittedly, at Brigham Young University, the Latter-day Saint society is somewhat transcendental- even with its sparse dishonesty and other moral faulting it is elevated from the world population in terms of kindness, respect, and general charity. However, the society of Summer Scholars was greater than all of these. With its low, near one hundred-student population, it could be self-governed almost entirely by these moral principles alone. I do not claim to have taken these moral principles with me entirely and used them all in my life, but it gave me a perspective of society that increased my happiness tenfold. I lost my cynicism and I lost my vision of a competitive society forever. I learned to find joy in people. I regained my smile I had lost so long ago.

Investigate the root causes of major Engineering disasters that have Essay

Investigate the root causes of major Engineering disasters that have occurred since 1800 - Essay Example In engineering, most disasters that have occurred portray a possibility of overlooking one or more provisions of safety with some being caused by poor decision-making and ignorance. The Chernobyl Power plant disaster The Chernobyl Nuclear power plant disaster of April 26, 1986 although blamed on negligence on the part of operators had some engineering aspects that could have contributed in the disaster, in addition to the operation negligence. The Chernobyl plant used RBMK reactors that have been blamed for a number of negative features that may compromise the safety of the reactors and their operations. The RBMK reactors have neutron fields with high sensitivity levels towards movement of control rods, which results from having a high number of absorbers in the reactor core aimed at compensating for any extra reactivity (Malko, 1991). When some absorbers are withdrawn, especially affecting most of the absorbers in the peripheral zones, there results a local criticality. Moreover, RB MK reactors involve occurrence of huge positive reactivity that leads to a reduction of the period required to achieve stabilization of the power produced at the core to about 3 minutes (Medvedev, 1990). These factors make operations of a RBMK reactor problematic and uncertain in maintaining the safety of the reactor. Frankel (2010) observed that the Chernobyl reactor was designed to use graphite moderators that were typically unsafe, in addition to use of graphite rods. As a result, any possible loss of water in such a RBMK reactor posed great danger. Contrary to the operations of Pressurized Water Reactors (PWR), any water that circulates in the pipe network is only required to serve the purpose of cooling the reactor core only and not to moderate the core and cool it (Frankel, 2010). In PWR reactor cores, removal of the core cooling water would cause the entire chain reaction to abort. However in an RBMK-0100 reactor such as the one used in Chernobyl, in case water is lost due to closure of the supplying pumps as was the case, the graphite moderating rods continue to propagate and facilitate nuclear chain reactions (Frankel, 2010). Such mechanism, when considered alongside the loss of cooling water in the nuclear reactor core, would lead to overheating of the core in the shortest time possible. In such a case, the event of a core meltdown becomes the only possible event. In addition, in the Chernobyl RBMK reactors, the control rods were not designed as drastic safety features. Control rods are necessary for absorbing neutrons towards reducing or stopping chain reactions from taking place. However, in the Chernobyl RBMK reactors, control rods required about 20 seconds to reach the bottom of the core from their highest position (Medvedev, 1991). This was contrary to modern reactors that have well designed control rods, which  require one second or less, to reach the core of a nuclear reactor stopping any chain reaction. Therefore, in Chernobyl nuclear react or, the design and engineering of the entire core overlooked key safety mechanisms that could have prevented possible meltdown. The result of overlooking these safety considerations was the 1986 disaster. This was

Answer questions - Essay Example d. Coffee prices are expected to rise rapidly in the next few months. Indicate the immediate Effect. e. Workers in the coffee industry form a trade union and succeed with claims for higher Wages. Answers: a) When a severe frost destroys much of the Brazilian crop the supply curve of coffee will shift to the left. It is assumed that the demand will remain the same. Therefore the market equilibrium will shift to the left. b) If coffee is shown to cause cancer in laboratory experiments on mice it is expected that the demand for coffee will fall down sharply. The supply for coffee is assumed to remain the same. The demand curve will shift to the right and the new market equilibrium will also shift to the right. c) If the price of tea declines sharply the demand for coffee is expected to fall. The demand curve will shift to the left and the equilibrium point will shift to the left. d) If the price of coffee is expected to rise in the next month, the demand for coffee will rise immediately . Therefore the demand curve will shift rightwards and the market equilibrium point will shift to the right. The other conditions are assumed to remain unchanged. e) If the workers in the coffee industry form a trade union and succeed with claims for higher Wages, then the price of coffee will rise. ... In your explanation you must refer to aspects such as: Demand, wants, needs and desires Determinants of demand and supply Demand versus quantity demanded Movement along versus shifts of the curves Equilibrium Price and Quantity Surplus vs. Shortage. Answer: A market is a place where buyers meet sellers. The households purchase the products of their needs from the sellers in the market and the sellers charge their price. The determinants of demand and supply are the price of the good, the price of the substitutes, the income of the consumers, and the anticipated price level of the future and tastes of the consumers. An increase of demand can take place if the income of the consumers rise, the price of the product itself falls. The following diagram shows the demand supply analysis of the chosen product. In this case it is assumed that the market is competitive and so the demand curve is horizontal. In this case a parallel shift in the supply schedule leads to lower demand (Michigan St ate University, n.d. p. 1). The quantity demanded has fallen to Q1from Q0. The price is remaining the same in the market. A leftward shift of the supply schedule lead to fall in quantity demanded. The following diagram provides a clearer picture. In this case the supply curve shifted to the left while the demand curve remained unchanged. The initial equilibrium in the market has fallen as a result. The new equilibrium quantity is at a higher level than the initial one while the new equilibrium price is at a lower level than the initial one (University of Pittsburg, 2012, p. 2).
