Sea Based Logistics The second oldest of all transportation is sea based. Sea based transportation allowed for open trade worldwide. The military uses ships to transport massive cargo as well as troops to foreign countries. The most widely used ships in the world are cargo/ container ships for civilian usage. These ships carry thousands of tonnes of cargo as well as supplies to and from many different countries. As technology progresses, container ships are only going to get larger. One of the most notable sea disasters involved the transportation of one of the most precious cargo ever; crude oil. The following is an excerpt of the events leading up to the spill. 'The Exxon Valdez departed from the Trans-Alaska Pipeline terminal at 9:12 pm, March 23, 1989. William Murphy, an expert ship's pilot hired to maneuver the 986-foot vessel through the Valdez Narrows, was in control of the wheelhouse. At his side was the captain of the vessel, Joe Hazelwood. Helmsman Harry Claar was steering. After passing through Valdez Narrows, pilot Murphy left the vessel and Captain Hazelwood took over the wheelhouse. The Exxon Valdez encountered icebergs in the shipping lanes and Captain Hazelwood ordered Claar to take the Exxon Valdez out of the shipping lanes to go around the ice. He then handed over control of the wheelhouse to Third Mate Gregory Cousins with precise instructions to turn back into the shipping lanes when the tanker reached a certain point. At that time, Claar was replaced by Helmsman Robert Kagan. For reasons that remain unclear, Cousins and Kagan failed to make the turn back into the shipping lanes and the ship ran aground on Bligh Reef at 12:04 a.m., March 24, 1989. Captain Hazelwood was in his quarters at the time. The National Transportation Safety Board investigated the accident and determined five probable causes of the grounding: (1) The third mate failed to properly maneuver the vessel, possibly due to fatigue and excessive workload; (2) the master failed to provide a proper navigation watch, possibly due to impairment from alcohol; (3) Exxon Shipping Company failed to supervise the master and provide a rested and sufficient crew for the Exxon Valdez; (4) the U.S. Coast Guard failed to provide an effective vessel traffic system; and (5) effective pilot and escort services were lacking' (Cleveland, 2010). Although there are environmental and human factors threats to the shipping industry a more recent attack has poised the shipping industry on its edge. The threat is that of sea born piracy. Piracy has been a major problem for many years but since the late 1900s piracy has not been a problem until fairly recently since Somalia has a large coast line and many of the cargo vessels are easy targets. The shipping industry has truly revolutionized the logistics era; now with modern technology the weather can be predicted. Not just weather but under extreme conditions ships can safely navigate to and from harbors. With advanced technology on the ships as well it means less down time to fight corrosion. Air Based Logistics Air based logistics is the newest form of transportation. It does take a lot of coordination and planning. Many of the armed forces around the world utilize air transportation to get supplies to their ground forces as well as get their bases up and running. Today there is more than just airborne logistics in play, there are also sattelites that are used to scout drop zones. In stead of dropping in scouting teams it is more efficient to use a satellite or an unmanned aircraft. One of the best examples of air borne logistics is the use of satellites to aid in the relief effort of the 2005 tsuanamis. 'Satellite images are helping to target relief efforts in regions devastated by the Asian tsunamis of 26 December. The images may also yield clues about the shape and strength of the deadly tidal waves. The massive earthquake off the Indonesian island of Sumatra spawned massive ocean swells, which have killed an estimated 155,000 people and left millions more without clean water, food, or shelter. Relief agencies are using satellite images to find the hardest-hit areas. High-resolution satellites, such as the commercial satellite QuickBird, focus in on relatively small regions to show details as small as 0.6 metres across. These dramatic images can be used to discern damage to individual buildings. But satellites with lower resolution can provide a wider overview. USGS's Landsat 7 satellite, for example, images the entire globe in 180-kilometre swathes every 16 days, at a resolution of 30 metres. It passed over Sumatra's battered northern tip on 29 December, and on Tuesday scientists produced a map showing the areas most affected by the flooding'(McKee,2005). How All Of These Tie Into Logistics Logistics is a two part system of management and dispatch. The usage of these types of transportation has revolutionized the way logistics is dealt with. A product from across the world can be in the home in a matter of days or even a matter of hours if the buyer desires. To conclude if it was not for the different types of technological advancements and the field of transportation human kind would not have developed the means of advanced logistical design and implementation. 51Due作为专业的留学教育辅导机构,专业辅导essay代写-伯明翰assignment代写-paper代写-曼彻斯特论文代写,自2004年至今,坚持以学生为中心,全天候服务,为海外留学生完成了数万篇以上的论文,以优质的英国代写服务赢得留学生的信赖,有代写需求或者剑桥essay辅导、爱丁堡essay辅导需求的,可以咨询51Due哦。
