The redundant Icon DP 2 system is based on a triple controller solution with a redundant fibre-optic network. Interface to sensors and position reference systems, power system and thruster system are split into logical groups, based on class requirements and system segregation. The triple redundant controller solution features a two-out-of-three voting principle. In case of controller failure and voting rejection, the operator does not have to intervene.

The remaining two controllers are unaffected and continue the operation. The redundant network solution handles network failures locally on network level. The connected nodes do not need special functionality to handle network redundancy. With the DP system integrity preserved, the DP network is separated from networks of other applications. The DP cabinets, operator stations, sensors and position reference systems are dual powered from the redundant UPS system.

This useful brochure addresses the rolling bearings and will serve as a good workshop manual. It was specifically compiled and released by FAG Bearings Corporation specialists willing to share their experience and knowledge. The intention of the authors of this booklet was to provide a thorough survey of typical rolling bearing damage, find out the cause and propose required remedial measures. The procedures to follow to recognize the rolling bearing damage at earliest stages have also been presented at the start. The rolling bearings which were not classified as "damaged" are also inspected within the scope of preventive maintenance...

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.

The main declared objectives of the present computer based training course were to introduce the aims of the Risk Assessment, in order to describe the key stages in conducting effective Risk Assessment, i.e. identifying hazards, evaluating severity, estimating likelihood, assessing the risk level of hazards, and managing risk, to outline the benefits of doing Risk Assessment, and to provide a number of working examples of the key steps of Risk Assessment and comprehensive practice exercises.

There are two major components of Risk Analysis, namely Risk Assessment and Risk Management. This course has been partitioned into three main components, that are followed by a practice exercise and finally a short test. The first part contains the introduction to risk assessment. The second part covers the hazard investigation, evaluating risks, and existing preventative measures. The third part of the course contains description of the further preventative measures, review and monitoring of the action plan, and record keeping.

Then there are practice exercises followed by the final test. All employers have a so-called "duty of care" aimed to ensure the health and safety of their employees and other persons on board by means of proper evaluation of the risk levels and taking appropriate actions to reduce such risks...

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 rigging of the vessel models is considered one of the most complicated tasks taken by every model maker. The vessels of the eighteenth century could boast miles of rigging, more than thousand blocks and literally acres of canvas the sails were made of. It is very difficult to retain the accurate representation when trying to reduce these all in scale.

The present classic work by Lennarth Petersson is intended to untangle this complex web using more than four hundred ship drawings; the author of the volume has clearly demonstrated how each of the rigging items was fitted to the ship's masts, sails and yards. Each drawing addresses a single particular rigging item to let the readers see it isolated. The visual immediacy together with the remarkable clarity of this publication has made it very popular among the ship modelers and naval history enthusiasts, resulting in a truly unique volume.

The ship modelers from all parts of the world have already found the book very practically useful and interesting, treating it as a real must-have reference source to be used by all people engaged in the rigging/repair of historic vessels. The book is very handy and helpful since the content is full of informative images guiding the reader. t will ask all your questions and solve all problems you may face...
