Marine Ship Safety And Precaution Questions For Exam

The statement is true because it is important to check the planned route on the charts before each voyage, during the voyage, and prior to arrival. This is necessary to ensure that the ship is following the correct path and to avoid any potential hazards such as shallow waters, reefs, or other navigational obstacles. Checking the charts regularly helps the crew to stay on track and make any necessary adjustments to the route if needed. It is a crucial part of navigation and ensures the safety and efficiency of the voyage.

The officer in charge of a navigational watch is responsible for the safe navigation of the ship. They act as the Master's representative and have the primary responsibility to ensure the ship is safely navigating at all times. Therefore, the statement "The officer in charge of a navigational watch is the Master's representative and is primarily responsible at all times for the safe navigation of the ship" is true.

The statement implies that it is the duty of the parties involved to make sure that the principles of safe watchkeeping are upheld consistently. This suggests that the responsibility lies with the parties themselves to ensure the safety and security of the watchkeeping process.

The statement suggests that the professional competence of the officers and crew plays a role in deciding the makeup of the watch. This means that the individuals who are deemed competent and skilled in their roles are selected to be part of the watch. Therefore, the statement is true as it implies that the composition of the watch is influenced by the professional capabilities of the officers and crew.

The correct answer is "when you are satisfied of the manner the turn over has taken place." This means that as an OOW (Officer of the Watch), you start your duty once you are confident that the transition of responsibilities from the previous officer on duty has been completed properly. This ensures a smooth handover and allows you to take charge of your duties effectively.

The magnetic compass is affected by changes in the Earth's magnetic field, as well as any alterations in the course of the vessel. Therefore, it is important to check for errors in the compass, especially after major changes in course. This ensures that the compass is providing accurate readings and helps maintain navigational safety.

During the turnover of watch in an open sea, the draft of the ship is not important. The draft refers to the depth of the ship's hull below the waterline. While the position, speed, and course of the ship are crucial for navigation and safety, the draft does not directly impact these factors. Therefore, it is not essential information during the turnover of watch.

A "look out" is a person who is responsible for watching and observing any potential hazards to navigation using their sight and hearing. They are tasked with keeping a lookout for any dangers such as obstacles, other vessels, or changes in weather conditions. This role is crucial for ensuring the safety of the vessel and its crew. The term "look out" is commonly used in maritime contexts to refer to this specific duty.

Keeping a record is the most effective way to document activities and movements in relation to the safe navigation of the ship. By maintaining a detailed record, the crew can provide accurate information to the master regarding their actions and observations. This documentation helps in assessing the ship's navigation, identifying any potential risks or issues, and ensuring compliance with safety protocols. Additionally, keeping a record allows for future reference and analysis, aiding in the improvement of navigation practices and the overall safety of the ship.

Rule 7 of the International Regulations for Preventing Collision at Sea states that every vessel shall use all available means to determine the risk of collision and to take avoiding action. This includes the use of radar, which is an important tool for watch keeping as it helps in detecting other vessels, determining their position, speed, and course, and assessing the risk of collision. Therefore, the necessity to comply with the use of radar in watch keeping is mandated by Rule 7.

The statement implies that the officer in charge of the navigational duties has the authority to take immediate action for the safety of the vessel without seeking permission from the master. This suggests that the officer has the necessary expertise and responsibility to make decisions in critical situations. Therefore, the statement is true.

During a voyage, it is important to verify the courses for the planned route. This means ensuring that the intended course is accurate and safe for navigation. By checking the courses, the crew can confirm that they are following the correct path, avoiding any potential hazards or obstacles along the way. This verification process helps to ensure the safety of the vessel and its occupants during the voyage. Therefore, the statement is true.

The minimum 10-hour rest period is required for the Officer of the Watch (OOW) and the ratings who are part of a watch. This regulation ensures that these individuals have sufficient time to rest and recover between their shifts, promoting safety and preventing fatigue-related incidents. By enforcing this rest period, the maritime industry aims to maintain the alertness and performance of OOW and watch ratings, ultimately ensuring the smooth operation of the vessel.

When you find out that your relieving officer is incapable of performing his duty due to drunkenness, the best course of action would be to inform the master and continue the watch. This ensures that the master is aware of the situation and can take appropriate action, such as finding a replacement for the officer. By continuing the watch, you ensure that the bridge is still manned and the safety of the vessel is maintained.

Rule 7 of the COLREG mandates the use of radar for vessels under certain circumstances, such as when visibility is restricted or when there is a risk of collision. Rule 19 also requires vessels to use radar to determine the risk of collision and to take appropriate action to avoid it. Therefore, the correct answer is Rule 7 & 19.

The correct answer is "when you are satisfied of the manner the turn over has taken place." This means that as an OOW (Officer of the Watch), you start your duty once you are confident and content with how the handover process has been conducted. This ensures that you have all the necessary information and data from the previous watch officer, and that the transition has been smooth and satisfactory. Starting your duty in this manner helps maintain a high level of safety and efficiency on the bridge.

Gyro error refers to the deviation or inaccuracy in the readings of a ship's gyrocompass. This error does not have any direct impact on the course and speed of the ship. The gyrocompass is primarily used for determining the ship's heading and not for controlling its course or speed. Therefore, any error in the gyrocompass readings would not affect the ship's course and speed directly.

If the presence of the master is on the bridge during your watch, the correct action would be to continue being responsible for your watch. This means that you should not hand over the watch to the master or update them on the ship's condition. Instead, you should carry out your duties and responsibilities as assigned and maintain control of the watch until your shift is over.

As a 3rd Officer in your first week of command, your immediate action should be to take immediate action and notify the master. This means that you should take immediate steps to avoid the collision, such as changing course or speed, and then inform the master of the situation. This is important because the master is the ultimate authority on the vessel and should be made aware of any potential risks or emergencies. By taking immediate action and notifying the master, you are demonstrating your ability to make quick decisions and prioritize the safety of the vessel and its crew.

A relieving officer cannot take over the watch even if they are sick, even with approval from the master.

The correct answer is "precaution." In order to prevent pollution to the environment, it is important for the master, officers, and ratings to take all possible precautions. This means being proactive and taking measures to avoid any harm or damage to the environment. By being cautious and taking necessary steps beforehand, they can ensure that pollution is minimized and the environment is protected.

The requirements listed are all necessary for planning a voyage, except for signal pennants. Signal pennants are used for communication between ships and are not directly related to the planning of a voyage. The other requirements, such as nautical publications, updated information about hazards to navigation, and adequate and appropriate charts, are essential for ensuring a safe and well-planned voyage.

The auto pilot is tested once every watch. This means that the auto pilot system is tested and checked for functionality and accuracy at regular intervals during a watch, which is a specific period of time during a ship's navigation. Testing the auto pilot ensures that it is working properly and can assist in steering the ship effectively and safely.

Rule 7 of the COLREG requires a compulsory use of radar, as it states that every vessel must use all available means to detect other vessels, including radar if available. Rule 19 also requires the use of radar, as it states that vessels must use radar to obtain early warning of the risk of collision and to obtain information about other vessels' actions. Therefore, the correct answer is Rule 7 and 19.

The statement is saying that if there is a reduction of at least 6 consecutive hours in the rest period, it should not last for more than 2 days. This means that if there is a reduction in rest period, it should not be prolonged for more than 2 days. Therefore, the answer "True" indicates that this statement is correct.

The helmsman is responsible for steering the ship and maintaining its course. While the ship is in manual steering, the helmsman needs to focus on operating the controls and ensuring the ship follows the desired direction. Therefore, they are not considered as a lookout, whose primary responsibility is to scan the surroundings for any potential hazards or obstacles.

The plotting or systematic analysis of the radar display should commence at ample time in order to be effective. This means that it should start early enough to allow for sufficient analysis and decision-making. Beginning the analysis at ample time ensures that any changes in the target's course or behavior can be detected and appropriate actions can be taken in a timely manner. Starting the analysis too late may result in missed opportunities or delayed responses, reducing the effectiveness of the radar display.

Determining the composition of the watch is important to ensure that there is a continuous lookout. This means that there will always be someone on duty who is competent and capable of maintaining a proper lookout. By determining the composition of the watch, the organization can ensure that there is always adequate personnel available to maintain the necessary level of vigilance and ensure the safety and security of the watch.

The correct answer is "a maximum of 70 hours in a 7 day period". This means that the maximum amount of time a person can work in a 7 day period is 70 hours. The other options mentioned in the question provide exceptions or alternatives to the minimum rest requirement, but this answer specifies the maximum limit on working hours.

After an officer has made a thorough observation of targets on the radar display, the appropriate procedure is to commence plotting and systematic analysis. This involves plotting the positions of the targets on a chart, analyzing their movements and patterns, and identifying any potential risks or collisions. This step is crucial in ensuring the safety and navigation of the vessel. Giving appropriate commands on the wheel and communicating with other vessels may also be necessary, but the first step is to commence plotting and systematic analysis.

Handling characteristics of the vessel refers to its response in terms of emergency stopping distance and turning circle. This means that it relates to how the vessel behaves and reacts when it needs to stop abruptly or make a turn. It is not directly related to the size and weight of the vessel, or the size of the rudder and propulsive power.

In this situation, the best course of action is to notify the master. By informing the master about your doubt and seeking guidance, you can ensure that you are following the correct protocol and taking the appropriate action. The master is the highest authority on the ship and is responsible for making important decisions, so reaching out to them will help you overcome your doubt and ensure that you are acting in accordance with the established procedures.

As the OOW (Officer of the Watch), you may be the only person responsible for keeping watch on the bridge, but this condition can only be met if doubts about the situation have been carefully assessed. This means that before being the sole lookout, you must ensure that any uncertainties or concerns about the current situation have been thoroughly evaluated and addressed.

Determining the composition of the watch is important to ensure that there is a continuous lookout. This means that there is always someone on duty who is competent and capable of maintaining a proper lookout. By determining the composition of the watch, it can be ensured that there is no gap in the lookout duty, which is crucial for the safety and security of the operation.

The OOW (Officer of the Watch) is not solely responsible for taking possible precautions to prevent marine pollution on board a vessel. While the OOW does play a role in ensuring the vessel follows pollution prevention measures, there are other crew members and departments involved in this responsibility as well. This includes the ship's captain, engineers, and other crew members who are responsible for the proper handling and disposal of waste materials. Therefore, the statement is false.

The correct answer is "give a minimum of 1 mile passing distance for collision avoidance." This is not a standing order because it is a rule or guideline for avoiding collisions, rather than a standard procedure or instruction that is followed consistently. Standing orders typically refer to specific protocols or tasks that must be carried out regularly or as a standard practice on a ship.

The correct answer is "unmanned machinery space." This term refers to a designated area on a ship or vessel where machinery and equipment are operated and controlled remotely or without human presence. It is important to have unmanned machinery spaces to ensure safety and efficiency in maritime operations.

The statement is true because an echo sounder can be used as a position fixing instrument when needed. An echo sounder is a device that uses sound waves to determine the depth of water. By measuring the time it takes for the sound waves to bounce back from the seabed, it can calculate the depth. In addition to determining depth, an echo sounder can also be used to determine the position of a vessel by measuring the distance between the vessel and the seabed. This can be useful in situations where other position fixing instruments may not be available or accurate enough.

The statement is false because it states that the Master shall consult the Chief Engineer for any changes in the composition of the navigational watch. However, in reality, the Master is responsible for deciding the composition of the navigational watch and does not need to consult the Chief Engineer for any changes.

The condition of the cargo is not a factor required to satisfy a relieving officer before taking over the watch. Factors such as the master's night order, factors affecting speed and course, and procedures in the use of the main engine are all important considerations for the relieving officer to ensure a smooth transition and safe operation. However, the condition of the cargo is typically the responsibility of the cargo officer and not directly related to the watchkeeping duties of the relieving officer.

The officer on watch alone in the bridge may break the continuity of watch while doing the manual steering in a non-emergency situation. This means that if the officer needs to manually steer the ship, they are allowed to temporarily leave their post and perform this task, even if it interrupts their continuous watchkeeping duties. Therefore, the statement is false.

The appropriate action for the 3rd Officer to take before using the engines and sound signaling apparatus for collision avoidance is to provide timely notice to the engine room of the intended change. This ensures that the engine room is aware of the upcoming change and can make the necessary adjustments or preparations. By notifying the engine room in advance, the 3rd Officer can ensure that the engines and sound signaling apparatus are ready to be used effectively for collision avoidance.

When action is being taken to avoid a hazard, the relief of the officer shall be deferred until such action has been completed. This means that the officer's replacement or substitution will be postponed or delayed until the necessary steps to prevent the hazard have been carried out.

The reason to call the master in all the given options is related to potential risks or uncertainties in navigation. However, being in doubt about the maneuvering characteristics of the vessel does not pose an immediate danger or require immediate intervention from the master. Therefore, it is not a valid reason to call the master.

The correct answer is "at a short period and safe to do so." As the Officer of the Watch (OOW), it is important to regularly visit the chart room to perform navigational duties. However, the frequency of these visits should be determined by the need and safety considerations. The OOW should prioritize their duties and ensure that they have a lookout while performing other navigational tasks. Therefore, they should visit the chart room at regular intervals that are short enough to maintain situational awareness and safety.

Proper lookout must be maintained at all times in compliance with Rule 5 of the STCW code to appraise the situation and risk of collision. This is necessary to ensure the safe conduct of passage. It is the prime duty of an efficient and competent officer to be aware of the surrounding environment, including other vessels, navigational hazards, and potential collision risks. By maintaining a proper lookout, the officer can assess the situation, anticipate any potential dangers, and take appropriate actions to avoid collisions and ensure the safety of the vessel and its crew.

Taking over while the maneuvering action is taking place is not a principle that should be followed in taking over the watch. This is because during maneuvering action, the ship's position, course, and speed may be changing rapidly, which requires the current watchkeeper to have full control and awareness of the situation. Taking over during this time can lead to confusion and potential safety risks. It is important to wait for the maneuvering action to be completed before taking over the watch.

The planned route is clearly displayed in the appropriate chart. This is the most logical answer as the chart room is where charts are typically kept and maintained. The appropriate chart would be the one that corresponds to the specific route being planned. Displaying the planned route in the bridge or in the most convenient place may not provide the necessary accuracy and clarity required for navigation.

When maintaining a proper lookout, the master should consider various factors to ensure the safety of the vessel. Visibility is crucial as it allows the master to see any potential hazards or obstacles in the surroundings. Dense traffic is another important factor to consider as it affects the vessel's maneuverability and requires extra caution. Sound signaling apparatus is also relevant as it helps in communication and alerting other vessels. However, steering control is not directly related to maintaining a lookout but rather to maneuvering the vessel. Therefore, it is not a relevant factor to consider in this context.

When an officer is alone on the bridge in collision avoidance, it can contribute to the vessel being highly dangerous on automatic steering. This is because the officer may not have enough time or attention to properly monitor the automatic steering system and make necessary adjustments to avoid collisions. Without another person to assist, the officer may be overwhelmed with the multiple tasks and responsibilities required for safe navigation.
