Though the Robotic Sailing conference held in 2011 was only the fourth in a series of robotic sailing conferences, the organizers of this important event have noticed a significant increase in the number of people working on and interested in the field of robotics sailing. This official publication contains the proceedings of the Fourth conference and was released with the intention to duly summarize the state of the art in this area.
The first introductory part of the volume provides all interested parties with a good review that illustrates the history as well as very latest developments in robotic sailing. It is very important to clearly understand that possessing a reliable and robust boat shall be considered a basic and key requirement - this is what the part two of the book is mainly focusing on. The proposed boat designs are ranging from smaller one-design boat for development of the algorithms to the ships able to sail across the Atlantic Ocean.
Part three of the book discusses some technical aspects of the system design and validation. The other papers that have been included in this part concentrate on algorithmic issues. The remaining parts of the book deal with the approaches applied to collision avoidance, localization and route planning.
Marine International CFD Conference hosted by RINA in 2011. Some of the topics that have been discussed during that conference - Prediction of the ship wakes using the CFD, ship wake prediction, using these calculation methods for the improvement of predictions of ship manoeuvres, stern challenge, analysis of the craft resistance of the small crafts, trim wedge optimization, cavitating flow analysis in a tunnel thruster, design of the propulsion nozzles using auto-optimization routines, stabilizing fins design, OpenFOAM application, viscous flow computations, and many more...
The first one deals with the simulation of the self-propelled vessels with different computational flow dynamics methods, presented by the expert of the University of Genova. Today, the RANS solvers are considered a standard for and analysis of the flow measure and numerical prediction. Such method takes into consideration the hydrodynamic forces that act on the hull of the vessel, as well as the free surface effect.
It can be effectively used for the design/analysis of the ship propellers; note that the fact of the ship being self-propelled requires a very accurate solution of both above mentioned aspects that interact strongly. Unfortunately, the time and signal scales are difference for the hull and for the propeller...
Another compilation of the technical papers - these were presented during the international CFD conference held in 2008. The publication starts with the paper dealing with the effect of the internal pump towers on fluid sloshing in rectangular containers. The other articles cover the following interesting and practically actual topics, namely Sloshing and LNG carriers; LNG tank layout; LNG carrier pump tower; Sloshing problem; Tank with pump tower; Computational model; Pump tower; Wall pressures; Pump tower force; Impact with air entrapment; Blend Factor: Pre-Impact... Enhancement of marine craft design through the CFMS program; Use of CFD for the design of hull and appendages on an OPV and wake focusing effect identification; Floating vessels resistance - prediction; Different methods and practical aspects of tight and loose coupling of CFD and CAD; Developing the numerical towing tank applying the European approach; Rudder cavitation prediction on the basis of the full-scale observations and CFD; Transient shaft forces determination in thrusters and water jets... and many more interesting articles and topics that were presented in the course of the conference in 2008...
This publication by The Royal Institute of Naval Architects contains all materials of the Marine CFD - The Fourth International Conference of Marine Hydrodynamics held in 2005. It includes very interesting articles and researches by the world famous professionals. Among the topics addressed by the participants of the event there were dynamic mesh simulations of unsteady hydrodynamics of the ship, numerical simulation of yaw effect and free surface wave induced separation, scale effect influence on the propeller's hydrodynamic characteristics, prediction of the torque and thrust performance, various considerations on deviation in prediction of the torque, practical boundary element code development for hydrodynamic analysis, free-surface elevation around a moored vessel etc.
We all know that hydrodynamic aspects play a critical role in the quality of a vessel. The powering performance and hull resistance are considered dominant criteria for the ship hull form design. Moreover, vibration and noise that may seriously affect the passenger and crew comfort, often have the hydrodynamic origins and may be caused by stemming resulting from the operation of the propeller.
The present compendium contains all technical articles that have been introduced by various reporters during the International Conference held by RINA in 2005. Among important topics covered there are important Regulatory Matters, i.e. National and International Regulations as well as various relevant Industry Guidelines and Voluntary Codes of Practice, The Implementation and Safety Issues relating to the Green Passport, and putting necessary procedures into Practice, The Standard Contract for Ship Recycling; Ship Recycling in different countries — economic and environmental aspects, Assessment of the Future Demolition of Ships Utilizing Artificial Intelligence; HSE matters in Shipbreaking, Facilities for Safer Ship Dismantling, and many more.
This publication starts with the first section addressing the applicable regulatory matters and guidelines. Apart from the general introduction, it addresses both mandatory and voluntary provisions together with their application and further enforcement, describes the reporting system being considered within IMO, touches the matters of buying and selling, provides the basic information on the Basel Convention including the issues relating to the applicability of this Convention to vessels.
This informative volume contains all materials of the international workshop that was held in 1999 by the NRC (National Research Council) - they were collected in order to summarize the data and discuss the significance of the role of marine bio-technology in the prevention of the marine environment degradation together with its restoration and remediation. Each of the participants of that scientific event touched the current situation and tried to highlight the real research needs.
Among the important topics discussed by the speakers there were restoration of coral reefs, negative impact of heavy metals, possible strategies for prevention or at least inhibition of bio-film development, oil spill remediation etc. They have also tried to check the most important gaps in the technical knowledge possessed by the marine science community. These proceedings have been very carefully reviewed by the respected industry experts chosen for their remarkably diverse perspectives as well as prominent technical expertise as per with the established procedures.
It is definitely suggested that this set or technical documents is checked by every person involved or interested in the marine environment protection, because of the quality and up-to-dateness of information contained.
Here is a brief contents of the publication - the articles selected for inclusion into this compilation cover such interesting and practical topics as the development of heavy RAS, the future of the replenishment at sea, new concepts for fleet tankers - explorations into pricing and available options, cost effective and pragmatic environmental management of support vessels, twenty-first century support ships, the modular support ships considered as one low-cost answer to numerous needs, research and tool development applied to the support oh high-speed sealift concepts, automatic cargo handling, stern landing vessels, naval design through the innovative concepts of the sea-basing logistic support, application of the system engineering to UNREP design, landing craft motions in a flooded well dock and associated effect of well dock design, dynamic positioning and tracking onboard the Bay class LSD. The first of the documents provides some general information on the strategic context of the UK Royal Navy, followed by the equipment programme, some words about the current maritime environment and major naval assets, new platforms and introduction of the MARS programme...
