Physical oceanography

Introduction A vessel floating in water reacts to its environment with motion. It has six degrees of freedom, three translational and three rotational. When the floating vessel is attached to appendages, which in this case is mooring lines and risers, these attached slender structures also have effect on how the vessel reacts to the environmental loads. This study is to understand how these effects are analysed. In this chapter, the solution of the uncoupled and coupled analysis is going to be discussed. Cases for Analysis Two systems are developed for two cases of analysis. Case I: 500 m water depth Case II: 1000 m water depth Case I and II varies in water depth to represent the shallow water and deepwater. Comparing the two cases will show how the results differ in deeper water. The FPSO hull is the same for all cases. Two mooring system designs are defined for each water depth. Uncoupled and coupled analysis results will be compared in each case. The differences between the two methods will be compared for the two water depths as the water depth will have an impact on the coupled effects of the system. Hull model The storage capacity is a determining factor in the size of the FPSO. The relationship of the size and capacity of the FPSO can be seen in the scatter diagrams below. (Fig. 3.1 and Fig. 3.2) Figure 3.1 plots the length against storage capacity of the FPSOs. Each dot represents an FPSO. Both the length and the breadth of the vessel vary linearly with the storage…

Currents are the movements of the ocean produced by various causes. It may be divided into general and particular. The former depending on fixed and general causes which is always preserve the same direction and limits while the latter resulting from local and temporary ones vary both. The grand movement of the ocean from east to west or the equatorial current has a more complicated origin and the trade wind, so far from being the cause as has been supposed by some are probably in part the…

Sea level continues to rise in recent years, but also that the rate gradually accelerated, according to some data of observations. Sea level is rising primarily because as global temperatures increase, oceans are warming, which causes sea water to expand; and land ice is melting, which transfers water to the ocean. The rise of sea level will increase the risk of the coastal inundation. “Climate change will not introduce any new types of coastal hazard” (Manatu Mo Te Taiao, 2004), but the climate…

they are getting all their research well and of good quality. Work environment(s) Work on/with surface ships, satellites, aircrafts, underwater crafts and many other types of scientific equipment. Oceanographers may spend up to three months/year away from home. They can conduct field or work in an office where models and research is made. Office -- research, writing reports, analysing data, creating models and communicating with team members and anyone associated with the oceanographer…

The ocean is massive. Takes up 75% of the world and we have only explored 5% of the ocean. We also use the ocean for many resources like food and transportation. We also use the ocean to mine and get oil from. The ocean is our main source of recourses helping us human population thrive. Challenger expedition Challenger expedition of 1872 to 76 made multiple discoveries. Discoveries that laid out the foundation of oceanography. This expedition was made specifically to gather data on a wide…

The Beaufort Gyre, a major anticyclonic circulation feature in the Arctic Ocean, hosts a substantial fraction of the overall Arctic freshening citep{haine2015arctic}. The large-scale gyre circulation has been directly linked to its freshwater content (FWC) via the process of Ekman pumping that converges relatively fresh surface waters and deepens the halocline citep[e.g.][]{proshutinsky2002role}. The Ekman pumping arises due to transient anticyclonic winds that cause significant gyre…

Mariners, surfers, fishers, recreational boaters and US Navy personnel; virtually anyone subject to physical oceanography is additionally dependent on the monitoring and predictions of ocean waves and tides. Such predictions allow for one to decide when to sail into or out of harbors, where to tie or anchor their vessel, and whether it is safe or not to enter certain areas of the ocean. For recreational purposes, one can refer to wave and tide predictions when visiting tide pools along the coast…

closer study of marie life. Charles darwin (1809-1882) who, although he is best known for the Theory of evolution he contributed significantly to the early study of marine biology. His expeditions as the resident naturalist aboard the beagle from 1831 to 1836 were spent collecting and studying specimens from a number of marine organims that were sent to the British Museum for cataloguing. His interest in geology gave rise to his study of coral reefs and their formation. ) To become a marine…

biology is also very important to society because it is a job where they take care of the animals, keep them safe, and interact with them all at the same time. I chose to write about this career because it interests me a lot and I would love to be in touch with all different types of animals in my everyday life. The history of marine biology may not be as old as some other professions, but it is still very popular. This career didn't become an actual study until the nineteenth century by Sir…
