The identification of navigational risks of accidents in fairways is a basic principle for the construction or modernization of waterways in restricted waters and when the conditions of safe operation change. The estimation of navigational risk requires the evaluation of the consequences of accidents occurring in fairways: grounding, impact against a vertical shore, port/offshore structure or moored ship. When determining the consequences of these accidents, it is necessary to know the emergency maneuvering area and the speed of the ship at the time of the accident. The method of ship movement simulation in real time was used to determine the parameters of emergency maneuvering areas and the speed of vessels during the maneuvers. The results of the simulation experiment include full form vessels (bulk carriers, tankers) with a capacity ranging from 5,000 DWT to 100,000 DWT. The presented results of simulation tests enabled the evaluation of probability and consequences of ships’ accidents in fairways resulting from technical failures of ships’ steering equipment, allowing to assess the navigational risk for ships sailing through different types of fairways (approach channels, port entrances and inner port fairways).

NAVOICA – to systemowe rozwiązanie oferujące kursy MOOC (z ang. Massive Open Online Course) w Polsce. NAVOICA została uruchomiona w październiku 2018 r. i od tego momentu oferuje możliwość bezpłatnego dostępu zarówno dla twórców, jak i uczestników kursów MOOC. Na przestrzeni pierwszych 18 miesięcy na platformie NAVOICA zarejestrowanych zostało około 6500 użytkowników, co oznacza, że platforma pięciokrotnie zwiększyła liczbę uczestników kursów MOOC w ciągu ostatniego roku. Autorzy artykułu przedstawiają platformę NAVOICA po półtora roku realizacji kursów MOOC, omawiają zarządzanie platformą, system zapewnienia jakości, zgromadzone doświadczenie oraz modyfikacje i nowe funkcjonalności. Materiał zawiera zgromadzone doświadczenie w liczbach oraz wskazuje, w jakim kierunku będzie szedł rozwój oferty o kursy, których publikacja odbędzie się już wkrótce. NAVOICA jest efektem projektu tworzącego sieć współpracy uczelni i innych uznanych podmiotów kształcących na odległość. Jest to projekt realizowany na zlecenie Ministerstwa Nauki i Szkolnictwa Wyższego.

NAVOICA is a system for offering MOOCs (Massive Open Online Course) in Poland. NAVOICA was launched in October 2018 and, from that moment on, has been offering free access to both MOOC creators and participants. Approximately 6500 users registered with the NAVOICA platform during the first 18 months, which means the platform has quintupled the number of MOOC participants over the last year. The article’s authors present the NAVOICA platform after one and a half years of implementing MOOCs, as well as discuss platform management, the quality assurance system, the experience gained, as well as modifications and new functions. The material contains the experience accumulated in numerical form and indicates the direction in which the offer is to be expanded with soon to be published courses. NAVOICA is the result of a project creating a network for collaboration of higher education institutions and other well-established bodies providing distance learning. The project has been commissioned by the Ministry of Science and Higher Education.

The article presents a simulation method for determining the minimum safe pull of tugs assisting in port manoeuvres. The method can be used to determine the relationship between the minimum safe pull, understood as the tension on the line, of the assisting tugs and the overall length, cargo capacity or net capacity of ships manoeuvring in a given port under allowable hydrometeorological conditions. The method was verified through simulated tests of gas tankers’ entry, turning and berthing at the LNG terminal of Świnoujście.
