Manouvering and ship-handling simulation
The number of orders (for engine, bow thrusters and rudder) decreases with the use of the predictor. In this case, v,r,X,Y,N denote velocities and forces measured at amidships, andxG– the distance from amidships to the center of gravity. New capabilities of the NTPRO 4000 full mission ship handling simulator in the assessment and evaluation processes at.
Competency assessment can be obtained during the course of the exercise, but also afterwards. The evolution of simulation and its contribution to competence. The Journal of Continuing Education in Nursing. No mathematically rigorous formulas or procedures exist to achieve the design of input fuzzy sets; the correct determination of design parameters is strictly dependent on the experience of system behavior, and therefore the expert data derived from ship maneuvering tests are necessary.
In addition, the research uses a model of discretely arranged linear fenders as described in (Artyszuk, 2003) - the reaction of the fender increases proportionally with its compression, while it practically disappears during decompression. In the bow mooring, the latter lies approximately at one quarter of 86. The last four maneuvers (G0÷G3) comprise some examples of stern mooring at 5◦ relative to the mooring.
Table 3 shows that the largest contribution to the remaining total kinetic energy after the first impact, which actually comes from the rotation of the ship, is obtained by the fender near the middle part - the parameter %E1(ωz) represents the ratio of the energy associated with the twist and the total residual energyE1. Movement and energy absorption - simulation. of other symbols in both tables is the same as in Table 3. The second influence, although very important in certain circumstances, has so far received much less interest in the literature. The latter is always weaker than the first impact - this seems to be due to the hydrodynamic damping of the hull motions during the period until the ship finally reaches the side position.
At least in the case of B3 simulation (positive angular motion, i.e. the bow faces out of the berth) the stern shock is almost 2.5 times stronger in terms of energy than the bow stroke. For the aforementioned run B3 (Fig. 4), the very high reactions in the stern fenders are of the order of magnitude very similar to those of the first (bow) impact - both take about 90% of the breaking force, however the stern impact involves quite a large number of fenders that make possible to essentially 'resist' the second shock. Ship assessment – Evaluation of the vessel's main characteristics (current condition) and available equipment on board.
All policy statements of government agencies and oil companies involved in oil exploration and production off the coast of Finnmark say that “the contingency for shipping and maritime operations in the Barents Sea should be the best in the world”.

Global navigation satellite system
Operational and legal status of the Polish DGPS network is also mentioned in this context. It has been recognized that certain integrity monitor threshold settings are essential for the proper performance of the 104. The velocity information GPS uses the epoch single difference technique and the first order central difference approximation of the carrier phase rate.
The first part (800 sec) of the approach resembled an STS maneuver with STBL at anchor. In practice, the use of the GLONASS system in addition to the GPS system gives very poor results. The GPS system gives DOP coefficients of a value below three for the definite majority of the time.
Today, it is difficult to talk about positioning solely on the basis of GLONASS satellites. The compensatory effect of the two systems (although it is difficult to say unequivocally if this is not temporary) can be considered a promising premise for the future, when the number of GLONASS satellites approaches an operational level. The accuracy of the integrity monitoring system is characterized by SISMA (Signal In Space Monitoring Accuracy), which is broadcast to users through the integrity message along with satellite integrity flags (OK, Not Monitored, Don Not Use).
A review of the potential level of performance based on the preliminary results available from the development phase will also be provided. Integrity can be defined as a measure of the confidence that can be created in the correctness of the information that the system provides. In this context, SISMA can be considered a quality measure for the integrity control within IPF.
Before we delve deeper into the explanation of the Galileo user integrity concept and its potential applications for the maritime community, the Galileo cross-border concept needs to be clarified. This definition of the Galileo transboundary concept is very similar to the CDF (Cumulative Density Function) transboundary definition as stated by (DeCleene, 2000), although there are some differences as explained in (Hernández, 2008). The purpose of the IPF is to validate the navigation message from the satellites.
SISMA 2 );
The performance allocation to the various components of the system has been a very complicated process (Oehler 2008). Another performance driver is the quality of the raw data provided by the Galileo Sensor Stations (GSS). The situation is the same as for ICAO and the use of the Galileo SoL (Safety of Life) service within the framework of the civil aviation community.
Some preliminary results on the application of the concept of “transparency” in Galileo can be found in (Catalán, 2008). The result is sixteen possible forms of the cross-correlation function between the received signal and the generated replica. SUMMARY: The first EGNOS SIS (Signal in Space) tests in Poland were carried out on October 5, 2007 at the SPAN (The Synchronized Position Attitude Navigation) flight review at Mielec Airport.
Setting the GPS receiver to receive only the given sentence only simplifies troubleshooting. The user must set the serial link (RS232) to the baud rate of the GPS receiver. Conversion of ASCII symbols to the displayable data set of the GPRMC sentence in the NMEA protocol.
For Garmin GPS OEM receivers, a free program is available that allows you to set individual parameters of the GPS receiver. Data prepared in this way can be sent to the GPS receiver using the SEND CONFIGURATION TO GPS preamble as the final step of the configuration process. All newly defined parameters become valid after resetting (switching off and on) the GPS receiver.
The 2nd separator is followed by data that expresses the validity of data for that sentence. The GPS antennas were mounted on the antenna platform at the Maritime University of Szczecin. An effect of urban development on the accuracy of the GPS/EGNOS system, Gdynia: Akademia Morska.
Marine traffic control and automatic identification systems
A step-by-step approach to a common framework for charging transport infrastructure in the EU COM, where the "user pays" and "polluter pays" principles have been established. Severe weather in European short sea shipping: its impact on selected routes. The Journal of Navigation. In the first step of the study, the traffic system of transit vessels in Istanbul Strait was investigated and a simulation model was developed.
A scenario analysis is performed to evaluate the characteristics of the accident risk while the vessel moves along the Strait. First, to study and better understand the system, a functional simulation model of the transit vessel traffic in the Strait of Istanbul is built. Therefore, in the regions where the geography of the Straits tolerates it, it appears to be a safe practice (as also suggested by expert opinion).
The main contribution to the risk appears to be the combination of transit traffic and local traffic. The nature of the global economy and international politics dictate that maritime transit traffic in the Istanbul Strait cannot be greatly reduced or eliminated. This article discusses a comprehensive analysis of the security risks of maritime transit traffic in the Istanbul Strait.

Traffic control system is a set of pieces of equipment that change their states between the state of availability (i.e. the state of fitness to perform a task or function in the system) and states of non-availability at distinct moments in time, i.e. the course of availability in the case of application of the principle of inspection optimization.
