Synthesis Lectures on Ocean Systems Engineering - Böcker

The use of environmental data to support science, technology, and marine operations has evolved dramatically owing to long-term ocean observatories, unmanned platforms, satellite and coastal remote sensing, data assimilative numerical models, and high-speed communications. Actionable environmental information is regularly produced and communicated from quality-controlled measurements and skillful forecasts. The characterization of complex oceanographic processes is more difficult compared to inland features because of the difficulty in obtaining observations from often remote and hazardous locations. Regardless, coastal and ocean engineering projects and operations require the collection and analysis of meteorological and oceanographic data to fill information gaps and the running of numerical models to characterize regions of interest. Data analytics are also essential to integrate disparate marine data from national archives, in situ sensors, imagery, and numerical models to meet project requirements. Holistic marine environmental characterization is essential for data-driven decision making across the science and engineering lifecycle (e.g., research, production, operations, end-of-life).Many marine science and technology projects require the employment of an array of instruments and models to characterize spatially and temporally variable processes that may impact operations. Since certain environmental conditions will contribute to structural damage or operational disturbances, they are described using statistical parameters that have been standardized for engineering purposes. The statistical description should describe extreme conditions as well as long- and short-term variability. These data may also be used to verify and validate models and simulations. Environmental characterization covers the region where engineering projects or maritime operations take place. For vessels that operate across a variety of seaways, marine databases and models are essential to describe environmental conditions. Data, which are used for design and operations, must cover a sufficiently long time period to describe seasonal to sub-seasonal variations, multi-year, decadal, multi-decadal, and even climatological factors such as sea level rise, coastal winds, waves, and global ocean temperatures. Combined data types are essential for the computation of environmental loads for the region of interest. Typical factors include winds, waves, currents, and tides. Some regions may require consideration of biofouling, earthquakes, ice, salinity, soil conditions, temperature, tsunami, and visibility. Observations are also used for numerical forecasts, but errors may exist due to inexact physical assumptions and/or inaccurate initial data, which can cause errors to grow to unacceptable levels with increased forecasting times. Overall, marine environmental characterization tools, from observational data to numerical modeling, are critical to today's science, engineering, and marine operational disciplines.

As pointed out by other researchers, hybrid structures in ocean engineering are based on flat concrete foundations. Due to wave action these foundations are exposed to different pressure distributions on the top and bottom sides. As a result, the bottom side is exposed to a saddle type pressure distribution leading to huge forces on the foundation. Indeed, such huge forces have been observed at a number of offshore platforms installed in the North Sea.In an attempt to turn a problem into an advantage, the concept in this work aims to develop an integrated system to harness and harvest ocean wave energy right at the seabed. The long-term interest is to develop integrated devices that can be used as actuators or sensors, which, due to low manufacturing cost, can be employed in large quantities for control of ocean engineering systems, e.g., maritime renewable power-plants, or monitoring of marine processes, e.g., oceanographic sensing.A key element to the proposed system is the nonlinear coupled electromechanical oscillator unit, the dynamics of which are investigated with a novel approach in this work. The fundamental nature of the oscillator at hand makes it an excellent choice for applications involving oceanic transducers consisting of a dry driving electrical stator physically separated from a wet-driven payload mechanism. Without such units available at a low cost and a large number, harvesting the energy of a vibrating plate at seabed may prove impractical.

In a government-aided research project carried out at Cochin University, the inventor of the Water-Train demonstrated that his invention requires only 24 BTU/ton-km of energy whereas barges use 328 BTU in the same Inland water transportation situation.

The dynamic behavior of pipelines describes the time-varying continuous response of these structures under extreme effects, that are generated by the surrounding environment (waves and sea currents) and motions imposed by the host floating facility.

The inadvertent transfer of harmful aquatic organisms and pathogens in the ballast water of ships has been determined to have caused a significant adverse impact to many of the world's coastal regions. The international maritime community, under the auspices of the IMO has developed several documents, including the “International Conventions for the Control and Management of Ship's Ballast Water and Sediments, 2004”, (Ballast Water Management Convention), which are aimed at preventing the introduction of unwanted aquatic organisms and pathogens through the discharge of ballast water and sediments. The Ballast Water Management Convention applies to vessels registered in a country which is party to the Convention and to those vessels registered in other countries when operating in the waters of a country which is party to the Convention. As a means to prevent, minimize and ultimately eliminate the risk to the environment, human health, property and resources arising from the transferof harmful aquatic organisms and pathogens through the control and management of vessel's ballast water and sediment, as well as to avoid unwanted side-effects from that control, the Convention requires vessels to conduct a ballast water exchange or be fitted with an approved ballast water management system. It is noted that several studies have shown that the effectiveness of ballast water exchange varies and is dependent on the vessel type (design), exchange method (sequential, flow-through and dilution methods), ballasting system configuration, exchange location, weather conditions and vessel's trading pattern. For these reasons (and others), it has been determined that ballast water exchange does not provide adequate protective measures to prevent damage from organisms and pathogens carried in a vessel's ballast, even though exchange was considered to be acceptable as an interim solution.This book includes updates for the clarification of Survey requirements and adds the definition of biological commissioning, testing as well as requirements for Class approved Service Providers to conduct biological commissioning testing. Moreover, this book includes updates due to the adoption of the requirements from IACS UR M74, Rev. 2 and UR F45 and is applicable for existing ships, where an application for approval for the plans of BWMS is made on or after 1 July 2022; or for new ships contracted for construction on or after 1 July 2022.

Technical rules like the IGF code are developed by large groups of experts over long periods of time. As a result, the reasoning behind the rules is often lost over time, or at least hidden from the end user of the rules. The purpose of this publication is to explain the safety principles behind the rules for unconventional marine fuels.

Technical rules like the IGF code are developed by large groups of experts over long periods of time. Explaining the background for the requirements of such rules is not part of the development process. As a result, the reasoning behind the rules is often lost over time, or at least hidden from the end user of the rules. The purpose of this publication is to explain the safety principles behind the rules for unconventional marine fuels. It is the author's hope that an understanding of the safety principles will contribute to the technology-based interpretation of the rules and their further development.

The concerns related to levels and characteristics of noise and vibration are covered in this and the other titles in the series related to ship vibration and noise control.

Working and living onboard vessels imposes a series of generally low-frequency mechanical vibrations as well as single-impulse shock loads on the human body. Also, exposure to noise is characteristic aboard vessels. Low-frequency vibrations are created by vessel motions, which are produced by the various sea states in conjunction with vessel speed and point of sail. These motions can result in motion sickness, body instability, interruptions of task performance, sleep interruption and fatigue, increased health risk aggravated by shock loads due to slam and reduced human efficiency. Higher-frequency vibration influences comfort and is often associated with rotating machinery. The imposition of higher frequency vibrations (about 1 to 80 Hz) induces corresponding motions and forces within the human body creating discomfort and reduced human efficiency. With regard to noise, the above can similarly affect exposed humans, notably with sleep interruption and resulting fatigue, discomfort, and reduced efficiency. Also of concern are transient and permanent hearing loss, masking of audible signals, and interruption of speech communication. The concerns related to levels and characteristics of noise and vibration are covered in this and the other titles in the series related to ship vibration and noise control. be granted any of the associated habitability notations, specific noise and vibration criteria must be met. Ship designers in pursuit of these notations often request guidance on how to control levels of noise and vibration in inhabited spaces. As a result, this book has been written. The information presented in this book is intended for guidance only to support vessel designers and operators in controlling vessel noise and vibration in the general case, and more specifically in meeting the requirements of classification society habitability rules.
