Advances in Marine and Offshore Hydrodynamic Design

Dear Colleagues,

It has now been more than a century that the subject of hydrodynamics and its expertise has dominated the field of performing various hydrodynamic analyses. The purpose is to predict the performance of ships in the dynamic marine environment of ship resistance, propulsion, seakeeping, maneuvering, and, above all, stability of ships. With the advancement of computer capabilities, many of these calculations have transformed into numerical solutions and simulations. With offshore oil and gas discovery, marine hydrodynamics has taken a new twist and enabled a rapid rise in more robust calculations of first-order wave excitation forces and motion predictions. With the introduction of large offshore floaters, further research has established the second-order wave excitation forces and motions. Although the 2-D strip theory has comfortably taken care of a slender body with a forward speed for decades, it took some more time for a 3-D potential approach to take account of the same. Subsequently, CFD has fueled further the complete solutions of both potential and viscous regimes for floating bodies with and without forward speed. Over all these years, the entire hydrodynamic domain has been a healthy tool, from a simple problem-solving skill to a more complex design problem. In this century, we all face the more significant challenge of climate change and its detrimental effects on our environment and the planet we live on. So, there is a new paradigm shift in applying hydrodynamics to marine and offshore design problems. Today, the hull form of a ship will be different compared to the past for achieving energy savings to reduce carbon footprint, e.g., EEDI, EEXI, and CII. Propulsors need improvement and energy-saving devices for enhanced fuel efficiency. Apart from offshore oil and gas, offshore renewables are now facing new challenges—harnessing wind, wave, and tidal power. Multi-body simulations for offshore activities, sloshing analysis determining dynamic pressures, green sea analysis assessing the extent of the environmental forces acting on the vessel due to waves and shipping of green water, Station keeping (mooring and dynamic positioning), floating solutions (rising sea level for living and aquaculture) and maneuvering simulations for the prediction of standard maneuvers are now ongoing research in hydrodynamics.

The need for safe and environmentally friendly sea transportation, reduced air and noise pollution, reduced operating expenses by minimizing fuel consumption, offshore renewables in deeper water, and improved safety has led to the ongoing development of the innovative design of marine and offshore structures. In this development, the advances in hydrodynamic design of ships and offshore structures have been seriously challenged. Many researchers have investigated new hydrodynamic solutions to satisfy these requirements. During the last two decades, the idea of designing a ship and offshore structure with satisfactory hydrodynamic performance in both steady and unsteady flow evolved into the implementation of many new ideas.

The Guest Editor, Assoc. Prof. Dr Arun Dev, invites researchers, academics, PG researchers, industry bodies and research bodies to share their new findings in a Special Issue entitled “Advances in Marine and Offshore Hydrodynamic Design”. The Special Issue aims to provide an overview of hydrodynamic problems related to the broad variety of marine (ships) and offshore structures involved in transportation, oil and gas exploration and production, marine operations, renewable energy, different infrastructures, and aquaculture. In addition, the authors are inspired to submit high-quality articles directly related to the critical topics mentioned below.
