Pages 5
The tanker family is known for carrying a wide range of cargo from gas and crude oil to alcohol and acids. The Tanker family include some of the world’s largest ocean going vessels.. At just under half a kilometre long, the world’s largest tanker is more than 4 times longer than the average football pitch.
An oil tanker, also known as a petroleum tanker, is a commercial vessel designed for the transport of bulk oil. There are three basic types of oil tankers:
• Crude tanker and
• Product tanker
• Spcailised tankers
The Crude Tankers is the largest of the tanker group, carry big volumes of oil from the oil producing countries, such as in the Middle East and Gulf area, to the refineries located in across the globe.
Product Tankers, generally …show more content…
Fuel oil itself is very difficult to ignite, but its hydrocarbon vapours are explosive when mixed with air in certain concentrations. The purpose of the system is to create an atmosphere inside tanks in which the hydrocarbon oil vapours cannot burn.
Inert gas systems deliver air with an oxygen concentration of less than 5% by volume. As a tank is pumped out, it is filled with inert gas and kept in this safe state until the next cargo is loaded. The exception is in cases when the tank must be entered. Safely gas-freeing a tank is accomplished by purging hydrocarbon vapours with inert gas until the hydrocarbon concentration inside the tank is under about 1%. Thus, as air replaces the inert gas, the concentration cannot rise to the lower flammable limit and is safe.
As inert gas is introduced into a mixture of hydrocarbon vapours and air, it increases the lower flammable limit or lowest concentration at which the vapours can be ignited. At the same time it decreases the upper flammable limit or highest concentration at which the vapours can be ignited. When the total concentration of oxygen in the tank reaches about 11%, the upper and lower flammable limits converge and the flammable range

Al Qaeda Maritime Threat

...Akiva Lorenz in his essay “Al Qaeda's Maritime Threat” touches on some of the vulnerabilities of various transportation systems to Al Qaeda's asymmetric warfare, and then he moves to his main topic- Maritime Security. To date there have been three major successful terrorist attacks on maritime targets. The first was the 2000 attack on USS Cole while it was making a refueling stop in Aden, Yemen. The second was the 2002 attack on the French oil tanker USS Limburg while it was anchored off Yemen. Al Qaeda on the USS Cole and USS Limburg used small explosive loaded boats to attack their target. Usage of merchant vessels to facilitate terrorist attack is one of the four ways vessels can serve/ be used as weapon. The third major attack, and probably the one least familiar to Westerners, was the 2004 attack in the Philippines on Super Ferry 14. Mr. Lorenz uses these as stepping off points for his article and states that Maritime Terrorism is not well defined by International Law (terrorism is not well defined either) and given this lack of definition points out acts that might fall under "Maritime Terrorism": …the grey areas are cases of kidnap-for-ransom incidents, such as the May 2001 abduction of three American citizens and 17 Filipinos at the Dos Palmas resort on Palawan by Abu Sayyaf Group (ASG), an Al Qaeda affiliate. Motivated by the need to finance their political aims, ASG repeatedly perpetrated such acts of piracy. Their actions are an example of the blurring of the distinction...

American Petroleum

...According to the American Petroleum Institute, the industry is divided into sectors to cover all the procedures involved in finding, producing, processing, transporting and marketing oil and gas. These sectors include: 1. Upstream: involved in exploration and production of oil and gas using advanced geology to high-tech offshore drilling platforms 2. Downstream: involved in refining and marketing. It also includes the transportation of products using tankers from local terminals to service stations and ownership and operations in retail outlets. 3. Pipeline: involved in the movement of oil from ocean platforms and wells on land to refineries and finally to terminals where they are released to retail outlets 4. Marine: comprises all aspects of petroleum and its products movement by water, including port operations, maritime fighting and oil spill response. 5. Service and supply: includes companies that provide supplies, services, design and engineering support for exploration, drilling, refining and other operations. As with all other industries, there exist features that are peculiar to the petroleum. Common amongst these as identified in the 2007 UNCTAD report are: t finite supply of the product as it is non-renewable t differences in cost between production sites as a result constraints in technology, environment, etc that may exist in one site and not in the other t the industry is capital intensive and as such the risk level is high t in terms of demand and supply...

Exxon Valdez

...On March 24 1989 the tanker Exxon Valdez ran aground on Bligh Reef, Alaska, spilling just over 11 million gallons of crude oil, the largest oil spill until 2010. It is argued that the response was slow and inadequate and that safety was not properly followed by the staff at Exxon. In this essay we will look at the responsibility of this accident, and how implementing the main components of an ethical corporate culture, and a code of ethics could have helped to prevent such a tragedy from occurring. Many have speculated who was at fault for this horrendous accident. The National Transportation Safety Board even determined five possible causes for the grounding: 1) The third mate failed to properly move the vessel, potentially due to fatigue and excessive workload 2) The master failed to provide proper navigation, possibly due to intoxication 3) Exxon failed to supervise the master and provide sufficient crew for EV 4) The coast guard failed to provide effective traffic system 5) Effective pilot and escort services were lacking. However it is more likely a combination of all of those factors and the fact that an ethical corporate culture and a sound code of ethics were lacking that enabled all of the above to occur and a few more, which is really to blame for this tragic accident. Only eight months prior a meeting was held where it was determined that should a large oil spill, such as this, occur that they were not properly resourced, or experienced...

We’ve passed laws to fix this by preventing big business from ruining our environment, but we have yet to face the real problem. Our consumerism mentality has put the consumer’s desires before the health of the environment therefore our environment is suffering for the happiness of the consumer.

Jhonson and Jhonson: Tylenol and Exxon Valdez Case Study

...I. Background Information JHONSON AND JHONSON: TYLENOL The image and reputation of a company is so important in order to gain the trust of the consumers. Crisis need not strike a company purely as a result of its own negligence or misadventure. Often, a situation is created which cannot be blamed on the company - but the company finds out pretty quickly that it takes a huge amount of blame if it fumbles the ball in its response. On September 30, 1892, Jhonson and Jhonson announced that three persons had died as a result of taking Tylenol capsules that had been laced with cyanide. Within the next two days, four additional deaths from the same cause were reported. All seven deaths occurred in the Chicago Area, but J & J recalled thirty-one million bottles of Tylenol from store shelves throughout the nation. The publicity surrounding this was unprecedented in American business history; in the print media alone, more than 125,000 stories appeared. Many business analysts said that no product could survive this, and they pronounced Tylenol dead as a product line. From the outset of crisis, J & J recognized the immediate and long-term stakes involved. Its strategy was based on maintaining high visibility and avoiding any appearance that the corporation was trying to duck responsibility. The incident involved four specific “publics” – the management at Johnson & Johnson, its employees, the consumers and the stores which were selling Tylenol. By communicating with...

Faculty of Economics and Business Administration: MSc Program Business Administration. Prof. dr. Eduard Kimman course assistant: Karin Tjeerdsma (k.t.tjeerdsma@vu.nl) Background This course, in the setting of various Master Programmes at the Faculty of Economic and Business Sciences, is about the morality of professional people acting in the context of a business organization. Business organizations or organizations as such do have a formal structure in which responsibility ultimately lies with a director or the board of directors. A business organization forms a context for a great variety of decisions. In a juridical perspective the organization is the bearer of numerous transactions. Inside organizations one may find remarkable opportunities for just or unjust behaviour, for moral or immoral behaviour, for situations of equality or inequality which deserve to be evaluated ethically. As FEWEB is a school for the study of economics and business administration in an economic perspective we focus on so-called “economic decisions” which are decisions being taken with some form of economic calculus. In this course we will spend time on questioning whether the economic or financial outcomes of these decisions are morally neutral or deserve some further moral investigation...

Native American Environmental Issues

...Essay on Native American Environmental Issues by David R. Lewis This essay is taken from Native America in the Twentieth Century: An Encyclopedia, edited by Mary B. Davis and published in 1994 by Garland Publishers of New York. The encyclopedia includes additional essays on mining, natural resource management, hunting and fishing rights, and economic development. It's a highly recommended resource. Reprinted without permission for educational purposes. Traditionally Native Americans have had an immediate and reciprocal relationship with their natural environments. At contact, they lived in relatively small groups close to the earth. They defined themselves by the land and sacred places, and recognized a unity in their physical and spiritual universe. Their cosmologies connected them with all animate and inanimate beings. Indians moved in a sentient world, managing its bounty and diversity carefully lest they upset the spirit "bosses," who balanced and endowed that world. They acknowledged the power of Mother Earth and the mutual obligation between hunter and hunted as coequals. Indians celebrated the earth's annual rebirth and offered thanks for her first fruits. They ritually addressed and prepared the animals they killed, the agricultural fields they tended, and the vegetal and mineral materials they processed. They used song and ritual speech to modify their world, while physically transforming that landscape with fire and water, brawn and brain. They did not passively...
