Opis:: To meet the increased demands of new exhaust and CO₂ limits a research project of Volkswagen R&D, the Technical University of Poznan and the Ostfalia University of Applied Sciences has been initiated; its main target was the development and adaptation ICOS (Internal Combustion Optical Sensor) – an infrared sensor of LaVision for on-line measurements of EGR-rate in cylinder of an engine under operation. The objective of the project was to determine by different optical signals the CO₂ concentration, the EGR rate and residual gas which are cycle-resolved in the cylinder. In this paper the principle of measurement of optical indication has been described. The infrared sensor was validated by a one-cylinder diesel engine and compared to a synchronously running fast gas sampling system (CSV). Finally the practical application of various parameter variations is illustrated in the determination of the EGR and residual gas rate. Thus a new measurement technique for the development of future generations of engines introduced.
Aby umożliwić spełnienie wymagań nowych norm emisji spalin oraz spełnić limity emisji CO₂ podjęto projekt badawczy z udziałem: Volkswagen R&D, Politechniki Poznańskiej i Ostfalia University of Applied Sciences; jego głównym celem był rozwój i adaptacja ICOS (Internal Combustion Optical Sensor) – czujnika podczerwieni firmy LaVision dla bieżących pomiarów stopnia recyrkulacji spalin w cylindrze pracującego silnika. Celem projektu było określenie na podstawie różnych sygnałów optycznych wartość stężenia CO₂, stopnia recyrkulacji spalin (EGR – rate) oraz ilości spalin, które znajdują się w cylindrze przed rozpoczęciem procesu spalania. W artykule przedstawiono zasadę pomiaru zawartości spalin z wykorzystaniem czujnika optycznego. Możliwość zastosowania czujnika podczerwieni została potwierdzona przez badania na jednocylindrowym silniku wysokoprężnym, a otrzymane wyniki porównano z systemem do szybkiego pobierania próbek gazu (CSV). Przedstawiono również wyniki pozwalające na określenie recyrkulacji spalin oraz reszty spalin przy różnych parametrach pracy silnika. Nowa technika pomiarowa pozwala na dostosowanie nowoczesnych silników spalinowych do przyszłych norm ochrony środowiska i tworzy podstawę dla rozwoju przyszłych generacji silników spalinowych.

Opis:: Aquaculture is an industry that has developed rapidly over the past decades. Despite several hazards in the operations, emergency preparedness is not at the same level as in the rest of the maritime industry. This paper highlights some possibilities to increase the aquaculture industry’s coastal emergency preparedness. This paper is the result of the innovation project “Coastal Emergency Preparedness” funded by the Norwegian Research Council and industry partners. The aquaculture industry must establish its own emergency preparedness. In this paper, the innovation of a fleet of emergency preparedness vessels along the coastline, which could fill the gaps in emergency preparedness, is presented. The vessels would be of varied sizes, with different equipment and response times, and could assist the aquaculture industry during local incidents or large‐scale ones, such as algae blooms or winter storms, that affect many sites at the same time. Each production zone would need its own dedicated fleet due to biosecurity regulations. The emergency preparedness vessel fleet would be led by an on‐scene commander. The fleet would deal with oil spills and tasks such as emergency towing, firefighting, rescue of people, recapturing of fish, silage making, algae detection, and diving missions. With such a vessel fleet, small and large aquaculture companies could increase their emergency preparedness with a common strategy and shared resources.

Opis:: Automation and digitalization in logistic processes nowadays increase the complexity of logistic systems (supply networks, terminals and warehouses) and leads to highly linked systems. Their dimensioning as well as start-up and optimization of operational processes require technical assistance today. Simulation is used for understanding the behaviour of the seaport terminal and analysing the interaction of the complex processes at the terminal. This paper will show an investigation of the usage of specific port terminal simulator in the education of logisticians at university. It will show the effects of using simulation within the lessons in respect to the understanding of port operation and port simulation.

Opis:: Since January 2021, Havila Kystruten has been one of two companies sailing the coastal route between Bergen and Kirkenes. This paper contains information on the new shipping company Havila Kystruten and their 2019 bid for a 10-year operational license to sail the coastal route. The government's tender documents for the new license specified that the vessels operating the route had to be low-emission vessels. This requirement was in line with the government's white paper on the reduction of emissions for commercial and fishing vessels sailing in Norwegian waters. Thus, companies bidding for the new license had to offer new ships with low emission characteristics or rebuild existing vessels to obtain the low emission requirements. Based on the offers, the government decided to split the operational license between two companies. One part was given to the company previously operating the route (Hurtigruten) and the other to the new company Havila Kystruten. While Hurtigruten would rebuild the engine systems on some of their existing vessels, Havila Kystruten would operate the route using new vessels with low emission signature. The design requirements for these vessels were given by Havila Kystruten to the ship designer, Havyard Design and Solutions (now HAVDesign). Some of the requirements are listed in section 4 below. The latter part of this paper investigates the manoeuvring performance of the new Havila Kystruten vessels, containing a summary of a Research Council of Norway funded innovation project on harsh weather ship handling during port operations. The Port of Trondheim was selected as a case study.

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.

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.
