In this presentation, the author will briefly introduce an online database of potential and actual dropped object incidents – DORIS (Dropped Object Register of Incidents and Statistics) at first. Then the author
Seminar: Wind-tracing Floating Offshore Structures
Dr. Masoud Hayatdavoodi Associate Professor in Marine Hydrodynamics and Ocean Engineering School of Science and Engineering University of Dundee Dundee, Scotland, UK Offshore wind is a promising source of marine renewable energy, and one of the fastest-emerging energy alternatives. The UK and many other countries have invested heavily on wind energy, and it is expected that wind, along with solar, would be the two dominant forms of renewable energy soon. Main advantages of the offshore wind resources over near shore options include (i) access to more consistent and powerful wind, (ii) flexibility in site selections, (iii) elimination of visual
Seminar: Understanding the Fundamentals of Vortex-induced Vibrations: Research Past, Present and Future
Deniz Gedikli, PhD Assistant Professor Ocean and Resources Engineering Department, University of Hawaii at Manoa The canonical problem of fluid flow across an elastically mounted circular cylinder has been a widely studied problem in fluid mechanics due to the ubiquitous nature of the simple geometry in engineering applications and the resulting complexity of the fluid-structure interaction. In many engineering design and operation applications, it is advantageous to be able to predict fluid-structure interactions such as self-limiting vortex-induced vibrations, since these vibrations can strongly affect fatigue life or operational downtime in a variety of systems (e.g. motion of offshore structures, vibration
Experiments and Interpretation of Ice-Induced Vibrations of Offshore Structures
Dr. Torodd Nord Associate Professor Department of Ocean Operations and Civil Engineering Norwegian University of Science and Technology (NTNU) When drifting sea ice interacts with a structure, it may result in structural vibrations hence ice-induced vibration. With the potential to harm the structural integrity, secondary installations and operational safety, ice-induced vibration is an important problem that needs to be addressed in structural design. Since the first deployment of Arctic offshore platforms in Cook Inlet, Alaska in 1960s, extensive measurement campaigns have brought significant attention and knowledge to ice-induced vibrations. With today’s growing demand for renewable energy, the development of offshore
Seminar: Fluid-Structure Interactions in Offshore Engineering
Deniz Gedikli, PhD Assistant Professor Department of Ocean and Resources Engineering University of Hawai’i, Mānoa Technology, law and world’s appetite for more energy pushed oil-gas and renewable energy source exploration farther from the shores. Recent developments in this search have brought additional design challenges since these large offshore structures are more prone to the harsh environments around them. These factors require innovative approaches, in part because companies cannot operate in conventional ways in the Arctic region and in deep sea. This topic has critical importance to the offshore industry, particularly for the cost-effective development of new ocean structures such as
