Direct Perception Interface for Ship-Ship Collision Avoidance
2006 IEEE International Conference on Systems, Man and Cybernetics, 2006Ship-ship collisions have the potential to cause catastrophic marine accidents with human and economic losses as well as environmental pollution. Safe navigation is a major operative task for the officer(s) on the watch (OOW) as the ultimate responsibility for safe navigation resides with the human navigator. Though the universal use of automatic radar

Codification of Ship Collision
IABSE Congress Reports<p>Design of structures, in general, can be performed on several levels of sophistication. A main dis- tinction is often presented in the form of (i) risk informed analysis, (ii) reliability-based analysis and</p><p>(iii) design value or partial factor design. Of course, also in the most frequently used lowest design level the notions

Interaction of ice force in ship-ship collision
Volume 3: Structures, Safety and Reliability, 2015The maritime transportation system in the Northern Baltic Sea (NBS) is complex and operates under varying environmental conditions. The most challenging conditions relate to the presence of ice-cover, which for the NBS e.g. for the Gulf of Finland or Bay of Bothnia, can remain up to several months. The number of maritime accidents in these two areas is

Probabilistic Selection of Ship-Ship Collision Scenarios
Volume 2A: Structures, Safety and Reliability, 2013Within the framework of quantitative risk assessment and management in the design stage, it is essential to select relevant sets of accidental scenarios, while a huge number of possible scenarios are obvious. The current industry practices are likely based on prescriptive approaches for the most unfavorable accidental scenarios.

Quantitative research on ship domain based on ship collision avoidance
The 2nd International Conference on Computing and Data Science, 2021Based on the analysis of the concept of ship domain, starting from the reality of collision avoidance, according to the international rules for preventing collision at sea and the practices of seafarers in collision avoidance, the scope of ship field is quantitatively studied, so that the ships sailing on the sea always keep a safe area in different ...

Ocean Engineering, 1982
Abstract This paper described a procedure for simulation of the outer dynamics in ship collisions. The simulation procedure is derived using the transient equations for the horizontal motion of a ship. The hydrodynamic forces acting on the ships' hull during the collision are calculated by a strip method, where the forces acting on each section are ...

Journal of Navigation, 1978
FOR traffic proceeding in random directions on a plane surface the frequency of collisions, if no avoiding action is taken, is approximately proportional to the square of the traffic density and directly proportional to the size and speed of the craft. Avoiding action is normally taken and the rate of collisions is therefore also governed by additional

On the collision protection of ships
Nuclear Engineering and Design, 1976A brief survey of the literature extant on the collision protection of ships is presented herein. An examination of the characteristics of different energy-absorbing methods suggests that honeycomb structures provide a feasible alternative to deck structures which are currently used to achieve the collision protection of ships.

A COLREG-Compliant Ship Collision Avoidance Algorithm
2019 18th European Control Conference (ECC), 2019The compliance with the navigation rules plays a primary role in the development of routing algorithms to be applied in autonomous navigation. For such a reason this paper presents the mathematical formulations necessary to implement the Collision Regulations (COLREGs) within a previously developed ship path planning algorithm. The proposed approach is

NEW APPROACH TO THE COLLISION AVOIDANCE PROBLEM FOR A SHIP
International Game Theory Review, 2004A new algorithm is developed to solve the collision avoidance problem for a host ship subject to kinematic, dynamic, and moment equations and steered via rudder under the assumptions that the rudder angle and rudder angle time rate are subject to upper and lower bounds.
