Research on artificial intelligence safety prediction and intervention model based on ship driving habits

Based on the analysis of the causes of ship accidents, the development prospect and development direction of ship intelligent safe driving, the artificial intelligence safety prediction and intervention model is put forward. This model solves the problem of ship intelligent safety prediction by using intelligent analysis technology and network technology, and promotes the development of ship intelligence and ship safety navigation technology. Additionally, it expands the channels of obtaining information, connects the ship's mechanical and electrical equipment, collects, stores and analyzes the data reasonably, and constructs the intelligent analysis and processing platform of ship small-world data processing to implement intelligent intervention. What is impressive is that it makes ship navigation safer, more economical, more reasonable and optimized, and accelerates the development of ship artificial intelligence safe navigation.

TOWARDS A NEW SOLAS CONVENTION: A TRANSFORMA TION OF THE SHIP SAFETY REGULATORY FRAMEWORK

I congratulate the author of the article with his successful publication. The necessity to change the SOLAS is timely. Suggestions concerning simplifications in the application of the Convention, the use of more simple methods and delegation of greater freedom of choice for ship owners and designers have the right. In my opinion, the increasing use of probabilistic methods in the rules of the Convention is not always justified. For example, the Graph - analytical method that has been used previously to assess the unsinkable ship, gives the designer more opportunity than the current Probabilistic standard.

PROBABILISTIC SAFETY OF ESTUARY VESSELS BASED ON NONLINEAR ROLLING IN WIND AND WAVES

The author was previously involved in the development of the risk-based stability analysis which is now further extended, and used for the safety assessment of estuary container vessels subjected to stochastic action of beam wind and irregular waves. The study was motivated by the new set of safety regulations for estuary vessels issued by Belgian authorities in cooperation with Lloyd’s Register. These regulations introduce very innovative probabilistic ideas to ship stability regulations, and therefore present a significant step forward compared to the classical approach. Still, they do not account properly some important influences, such as wind gusts and motion nonlinearities, so considerably simplify the problem. The present investigation models the vessel motion much more realistically, analyzes the influence of beam wind and beam waves on the probability of a stability failure, and argues whether simplifications proposed by the regulations were justified. It is believed that presented method is not limited to the safety of estuary vessels only, but also gives important guidelines for a more general investigation of ship safety in wind and waves.

TOWARDS A NEW SOLAS CONVENTION: A TRANSFORMATION OF THE SHIP SAFETY REGULATORY FRAMEWORK

This document considers the necessary elements for fundamentally transforming SOLAS to adapt safety to innovation, technology sophistication and operational efficiency of shipping by means of a long-term comprehensive review of the existing regulatory framework. This should be undertaken with a view to ensuring that the Convention fulfils its mission and meets the future challenges, taking into account the ever-increasing pace of change and technological advancements made since 1974. This paper considers that a Goal-Based-Safety Level approach will provide the key to success and discusses the possibility to take a holistic approach to build a far reaching Convention that will help the stakeholders who deal with these regulations to be more effective.

ON THE APPLICATION OF THE EXTREME VALUE THEORY IN SHIP’S STRENGTH CALCULATIONS

The problem undertaken by the Author is fundamen- tal for ship safety and was discussed many times in the past (e.g. Boistov, 2000). However, the discus- sions did not dispel the Author’s or my doubts for the same reason: “If the calculations with the Ex- treme Value Theory of the probability of exceeding of the design hull girder bending moment are cor- rect, ships would suffer more severe casualties than previously observed.”

PROBABILISTIC SAFETY OF ESTUARY VESSELS BASED ON NONLINEAR ROLLING IN WIND AND WAVES

In the first place the discusser would like to congratulate Dr. Bačkalov with his paper, in which he assesses the new Belgian safety regulations for estuary vessels by means of a non-linear approach taking account the effect of a combination of beam waves and unsteady beam wind. The results presented are based on a solid, scientific background, and the author’s approach as published in former papers can be considered as the base of a promising methodology for evaluating the stability and safety of a vessel in waves and wind. As the discusser has supported the Belgian federal authorities in defining the methodology and formulating the present regulations, it is a pleasure to learn that the implementation of the latter is considered as a significant step in the general improvement of ship safety regulations.

DANGERS ARISING FROM APPLICATION OF THE PROBABILISTIC METHOD (AS INCLUDED IN SOLAS 2009 Ch.II-1) TO MEASURING LEVEL OF SAFETY OF CARGO SHIPS

From application of a probability based methods to evaluating safety of ships arise certain dangers of hazardous conditions omissions and results misinterpretations. In this paper a few areas in which these dangers occur are identified and described. The purpose of this work was to highlight these areas and suggest a way forward for developing methods for evaluation of safety of ships that would address these identified dangers. In this work the Author focuses on mathematical analysis of selected equations provided in the currently used method as included in SOLAS 2009 Convention. The following factors were selected for evaluation: pi – probability of a selected damage occurring, si – probability of surviving a selected damage, A – Attained Subdivision Index and R – Required Subdivision Index. From the performed analysis the conclusions are drawn that there are numerous areas where application of the investigated method may lead to dangers to maintaining controllable level of ship safety.

Analysis and Treatment of Electrical Fault of Ship Windlass

This paper aims at the electrical failure of the ship anchor machine, the potential causes of the failure are summarized and summarized by analyzing the electrical principle of the anchor machine. After the on-site failure investigation, the cause of the failure is accurately located, so as to put forward a feasible plan for the use and daily maintenance of the ship anchor machine. Because of its simple structure, stable operation and easy maintenance, the anchor machine is used for anchoring and maintenance of ships. Port docking is very important for ship safety and is widely used on ships.
