    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…

    Ocean Currents Causes

    • 4 Pages

    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…

    The Rise Of Sea Level

    • 1739 Words
    • 7 Pages

    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…

    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.

    Hectory Gyre Case Study

    • 916 Words
    • 4 Pages

    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…

    What can humans do to help reduce global warming? It might sound like a dumb statement but there is actually a lot of action that humans can take on to help out with global warming, but some of us either don’t know it or are unaware of this major ongoing problem that affects all of us. For example, we can choose to go green in our homes or bigger complexes such as apartments by the doing the most minimum changes to your house by doing things such as switching from the normal light bulbs to the…
