Emergency Towing
Opis:
The Norwegian Coastal Administration (NCA) is an agency of the Norwegian Ministry of Transport and Communications, and is responsible for services related to maritime safety, maritime infrastructure, transport planning and efficiency, and emergency response to acute pollution and drifting vessels. NCA has five regional Vessel Traffic Service centres. Of those, Vardø VTS has the special task of monitoring high-risk maritime traffic in Norwegian territorial waters, including the sea areas around Svalbard. Based on the history of ship incidents in Norwegian waters and lack of commercial tug resources in Northern Norway and the Svalbard area, the government decided in 2005 to establish a national emergency towing service. The establishment and coordination of this service was assigned to the Norwegian Coastal Administration. This paper briefly describes the development of the Norwegian Emergency Towing Service (NETS), how the service has changed over the years and plans for the coming years. Some cases involving emergency towing vessels are described. The paper also reviews the development of a national competence plan for senior officers on vessels employed by the Norwegian Emergency Towing Service.

Opis:
In this paper, a general framework for modelling stochastic service curves for communication networks is presented. It connects with each other two approaches to the traffic analysis and performance evaluation of communication systems, namely, the one which is called a deterministic network calculus with its stochastic counterpart. Thereby, it enables to treat any communication traffic in a consistent way. Further, as we show here, it enables also achieving new results. Derivation of the above model is presented in details in this paper. Finally, some hints are given how the method presented in this article could be applied in maritime telecommunications area.

Opis:
The aim of the paper is to analyse the length of time that ships spend in the Port of Gdansk. It is based on the examination of the time when ships come into and leave the port. Source of data used in the study is public web platform - Marine Traffic. Analysis which was conducted, enables to get information about duration of ships servicing in the port with a division into dimension, load capacity and type of the ship. Due to that information, it is possible to observe the duration of complete service for each vessel, including entering the harbour, reloading and the departure. Gained knowledge would allow to forecast, plan and model future development operations more properly. In addition, due to the method based on counting the number of hours that ships spend in the harbour, it is possible to estimate the amount of pollution emitted to the air.

Opis:
In the era of e‐Navigation, the future VTS is anticipated to play an important role on the enhancement of maritime safety and the efficiency of maritime transport as a key stakeholder of e‐Navigation. The VTS services need the advanced Traffic Organization Service(TOS). In this paper, the VTS functions for TOS is revisited from the reports of IMO e‐Navigation Correspondence Group and IALA VTS Committee. In Korea, the research activities to enhance the existing VTS functions have been conducted. In terms of TOS, some VTS functions have been developed. In conclusion, all the past traffic data and real‐time ship data are required to provide the advanced TOS. For this, the advanced functions to support TOS should be implemented on VTS console.

Opis:
The Norwegian Emergency Towing Services (NETS) is managed by the Norwegian Coastal Administration (NCA). In the early days of the NETS, the operational part was sheared between commercial tug companies and the Norwegian Coast Guard (NCG). A major change in the organization of the operation took place from January 1st 2020, when NCG was given the operational responsibility for NETS. This change is briefly described and the vessels in today's NETS are presented. Statistics for drifting vessels in Norwegian waters are presented before some selected recent maritime emergency incidents are highlighted. Actions by the NETS vessels and other NCG vessels will be highlighted. Handling of "FV Nortguider" after the grounding in Hinlopen (Svalbard) and the wreck removal work is one of the cases. The other two are drifting ship represented by the cruise vessel "Viking Sky" and the cargo vessel "Eemslift Hendrika". The final part of this paper discusses ways to ensure knowledge and operational experience sharing for personnel on vessels performing emergency towing tasks.

Term single window can mean the point of contact for communication in relation: ship – shore and shore – ship. In this sense, it is mentioned for example in the IMO Resolution A.950(23) “Maritime Assistance Service (MAS)” adopted on 5 December 2003. It can also mean a service or institution on land that collects all information related to safety of navigation before sending them on ships, as defined in the IMO documents on e-navigation. Directive 2010/65/EU of the European Parliament and of the Council of 20 October 2010 on reporting formalities for ships arriving in and/or departing from ports of the Member States and repealing Directive 2002/6/EC requires that vessels shall transmit reports mentioned in the IMO conventions and codes and European Union (EU) and national legislations only once through the national single window established in each EU member state not later than on 1 June 2015. The question is whether these different functions of above-mentioned contact points can be implemented by one shore based institution or service. The article contains an analysis of these issues and tries to answer the set question.

Opis:
The problem of vessel collisions or near-collision situations on sea, often caused by human error due to incomplete or overwhelming information, is becoming more and more important with rising maritime traffic. Approaches to supply navigators and Vessel Traffic Services with expert knowledge and suggest trajectories for all vessels to avoid collisions, are often aimed at situations where a single planner guides all vessels with perfect information. In contrast, we suggest a two-part procedure which plans trajectories using a specialised A* and negotiates trajectories until a solution is found, which is acceptable for all vessels. The solution obeys collision avoidance rules, includes a dynamic model of all vessels and negotiates trajectories to optimise globally without a global planner and extensive information disclosure. The procedure combines all components necessary to solve a multi-vessel encounter and is tested currently in simulation and on several test beds. The first results show a fast converging optimisation process which after a few negotiation rounds already produce feasible, collision free trajectories.

Opis:
Current development of the maritime transportation system, namely fleet and ports specialization, growth of vessel sizes, rationalization of routs, trade regionalization etc., has made many traditional approaches and calculation techniques practiced for many long years in port design procedures to be inadequate and insufficient. A generally acknowledged tool for this task today is the simulation technique. In the same time, modern object oriented simulation approach provides usually only ad hoc solution for a project. It lacks the generality that was the main and natural feature of its traditional analytical predecessors. Very high time and labor consumption of simulation comes to a conflict with a very narrow scope of the resulting model’s application domain. This paper describes a new approach used to create a simulation tool for the port designers and planners combining the universality and generality of the analytical (so called “static”) methods with the efficiency and accuracy of the object-oriented simulation. The concept represented in the paper was implemented in the software product, which enabled to conduct experiments that proved the validity and adequacy of the model. The simulation tool was used in several sea port design project and now is a common instrument of several leading port design and consulting company in Russian Federation.

Opis:
Vessel traffic flow is a key parameter for channel-through capacity and is of great significance to vessel traffic management, channel and port design and navigational risk evaluation. Based on the study of parameters of characteristics of vessel traffic flow related to channel-through capacity, this paper puts forward a brand-new mathematical model for one-way channel-through capacity in which parameters of channel length, vessel arrival rate and velocity difference in different vessels are involved and a theoretical calculating mechanism for the channel-through capacity is provided. In order to verify availability and reliability of the model, extensive simulation studies have been carried out and based on the historical AIS data, an analytical case study on the Xiazhimen Channel validating the proposed model is presented. Both simulation studies and the case study show that the proposed model is valid and all relative parameters can be readjusted and optimized to further improve the channel-through capacity. Thus, all studies demonstrate that the model is valuable for channel design and vessel management.
