Hi, thank you for your queries, this is a very good question which hopefully can clear everybody concept of the situation involving the two vessels, PDV (Power Driven Vessel) and CBD (Constrained by her Draft): 1. Initial Situation: When the PDV and CBD are in sight of each other and there’s no risk of collision (ROC), the PDV must avoid blocking (NOT TO IMPEDE) the CBD's passage. The CBD (Exhibiting Signal in Rule 28 - three all-round red lights in a vertical line or a cylinder). 2. Rules to Follow: o Rule 18(d)(i): In this no-ROC situation, the PDV should ensure it doesn’t impede the CBD. o Rule 8(f)(i): The CBD must take early action to provide enough room for safe passage. However.., when ROC exist, situation changed, then at this point, the rule No. 18.d.(i) is no longer can be implemented, however, the PDV required by Rule 8.f.(ii) is not relieve of her obligation her compliance to ROR 18.d(i) when she failed to give sufficient sea room and resulting ROC 3. If ROC Exists: If a risk of collision exists: o The PDV still needs to follow Rule 18(d)(i) and provide enough sea room. o Both vessels must comply with Rule 15, which governs how vessels should act to avoid collisions when both are power-driven. 4. Roles of the Vessels: o The CBD, classified as a PDV (Rule No. 3(h), shall KEEP OUT OF THE WAY (give way) to the vessel on its starboard side (PDV) and avoid crossing ahead of it. o The PDV, as the stand-on vessel, as required by Rule 17(c)(ii) when taking action to avoid collision in crossing situation with CBD, shall NOT ALTER change course to port when the CBD is on its port side. Instead, it can turn around to starboard to pass safely behind the CBD. This should help clarify the responsibilities of each vessel under different circumstances (with or without ROC). Feel free to ask and comment if you have more questions! Cheers!

Thanks for your question. Essentially, you're asking about how adding inert gas (IG) reduces the oxygen levels in the tank atmosphere to the left of line AB. To delve deeper into this, it's important to note that purified argon and nitrogen gases are commonly used as inert gases due to their abundance and low cost. When you inert a compartment like a tank, you're replacing the oxygen-rich air inside with an inert gas such as nitrogen or argon. This is done to create a safe environment by reducing or eliminating the presence of oxygen or other reactive gases. This is crucial in situations where the risk of fire, explosion, or unwanted chemical reactions is high. When you introduce the inert gas (IG) into the compartment, it displaces the oxygen present in the air. This occurs because the inert gas is denser than air, causing it to sink to the bottom of the compartment and push the oxygen-rich air upwards and out of the compartment. Moreover, if the inert gas is introduced at a sufficient flow rate or pressure, it can quickly displace the air, leaving minimal oxygen behind. This decrease in oxygen concentration makes it challenging for combustion to occur, which is vital in scenarios where fire prevention is paramount, such as in storage tanks for flammable liquids or gases. In essence, adding inert gas to a compartment reduces the oxygen concentration by displacing the air, thereby creating a safer environment where combustion is less likely to occur.

@prathamingle: Thank you for your inquiries. I'm delighted to discuss the Rules of the Road (ROR) concerning maritime navigation. In the context of Rule 18, it states: "Except where Rules 9, 10, and 13 otherwise require." Let's examine Rule 18 in detail: a. Power-driven vessels (PDV) underway shall keep out of the way: Not under command (NUC); Restricted in ability to maneuver (RAM); Fishing vessels (FV); Sailing vessels (SV). b. Sailing vessels (SV) underway shall keep out of the way: Not under command (NUC); Restricted in ability to maneuver (RAM); Fishing vessels (FV). c. Fishing vessels (FV) underway shall stand clear and avoid impeding: Not under command (NUC); Restricted in ability to maneuver (RAM). d. Any vessels other than Not under command (NUC) and restricted in ability to maneuver (RAM) shall avoid impeding crossing vessels. e. A Seaplane on the water (SPOW) must keep well clear and avoid impeding all vessels. f. Wing-in-ground (WIG) craft must keep well clear of all vessels and avoid impeding. ======================== Rules 9, 10, and 13 outline obligations for vessels navigating with others: Rule 9.b - Vessels less than 20 meters (V<20M) or sailing vessels (SV) shall not impede the passage of a vessels which can safely navigate only within a narrow channels or fairways. Rule 9.c - Fishing vessels (FV) shall not impede the passage of any other vessel navigating in narrow channels or fairways. Rule 9.d - A vessel shall not cross a narrow channel or fairway if it impedes the passage of another vessel that can only navigate within such channel or fairway. Rule 9.e(ii) - This rule does not exempt the overtaking vessel from its obligations under rule 13 (Overtaking). Rule 10.i - Fishing vessels (FV) shall not impede the passage of any vessel following traffic lanes. Rule 10.j - Vessel less than 20 meters (V<20M) or sailing vessels (SV) shall not impede the safe passage of a power-driven vessels (PDV) following a traffic lanes. Rule 13.a - Regardless of other rules (Contained in the Rules of Part B, Section I and II), any vessel overtaking another must keep clear of the vessel being overtaken. In the scenario provided, before the Risk Of Collision (ROC) exists, Rule 18.d applies, stating that any vessel other than Not under command (NUC) and Restricted in ability to maneuver (RAM) should avoid impeding crossing vessels. In this scenario, if the vessel in question is a fishing vessel (FV), or a vessel less than 20 meters (V<20M), or a sailing vessel (SV) (while in a traffic separation scheme), Rule 10(i) or 10(j) would be invoked, depending on the type of vessel involved. Keep in mind, the rules that giving an obligation for vessel navigating in conjunction with others: - Assess the vessels involved in any case. - In areas designated as Narrow Channels (NC), consider Rule 9(b), 9(c), 9(d). - In Traffic Separation Schemes (TSS), consider Rule 10(i), 10(j). - However, whenever any vessel overtakes another, Rule 13 - Overtaking must be adhered to.

@@l-marineservices6749 thank you sir for clearing the doubt. I also have 1 more doubt 1. A PDV is navigating in NC & CBD is crossing from stbd to port. It would be helpful if you explain the action (Who is STAND ON & who is GIVE WAY)

​@@PrathamIngle thank you for the insightful inquiry regarding these rules. Let me begin by thoroughly examining the situation to gain a deeper understanding: Two questions require clarification for better comprehension: 1. Firstly, in the current scenario, the Power Driven Vessel (PDV) is navigating within a Narrow Channel (NC), while the Constrained by Draft (CBD) vessel is crossing the NC from starboard to port. At this stage, no Risk Of Collision (ROC) has arisen. What proactive measures should the PDV take to avoid a collision? 2. Secondly, in this specific case, which vessel should act as the STAND ON vessel, and which vessel should act as the GIVE WAY vessel? Allow me to address the First Question initially: Let's define the situation: As mentioned earlier, it's crucial to consider the rules that impose obligations on vessels navigating alongside others. In this case scenario, particularly in areas designated as Narrow Channels (NC), Rule 9(d) should be taken into account. This rule states that "A vessel shall not cross a narrow channel or fairway if it impedes the passage of another vessel that can only navigate within such channel or fairway." Additionally, there's another relevant rule, Rule 18(d)(i), which states: "Any vessel other than a vessel not under command or a vessel restricted in her ability to maneuver shall, if the circumstances of the case admit, avoid impeding the safe passage of a vessel constrained by her draught, exhibiting the signals in Rule 28." Considering Rule 9(d) and Rule 18(d)(i), which rule should be applied in this case? It's important to recall the introductory statement of Rule 18 (Responsibility between vessels), which stipulates: "Except where Rules 9, 10, and 13 otherwise require." This implies that Rule 9(d) takes precedence in this scenario. CASE RULE: Rule 9(d) states that "A vessel shall not cross a narrow channel or fairway if it impedes the passage of another vessel that can only navigate within such channel or fairway." - As per Rule No 9(d) - You are in PDV which can only navigate in a Narrow Channel (NC), and you are expected that the Constrained by Draft (CBD) vessel intending to cross the NC shall not impede your safe passage. Firstly, before taking an action, ensure compliance with the following rules: - Verify if the approaching CBD is displaying the appropriate signal for a CBD as per Rule 28. - Given the absence of Risk Of Collision (ROC), there is neither a Stand On (Rule 17) nor a Give Way vessel (Rule 16), and it's not a Crossing Situation at this time. - As the CBD approaches on your starboard bow and intends to cross the Narrow Channel (NC), in accordance with Rule 9(d), it has an obligation not to obstruct your passage in the NC. - Per rule 8(f)(i), assess whether the CBD vessel, when required by the circumstances of the case, has taken early action to allow sufficient sea room for the safe passage of your vessel (PDV) in the NC. Your Course of Action: FIRST ACTION AND RULES TO COMPLY (WHEN ROC DOES NOT EXIST) (NO STAND ON, NO GIVE WAY VESSEL): 1. Maintain Safe Speed (Rule No. 6) and uphold proper lookout (Rule No. 5). 2. Monitor whether the CBD has taken early action to ensure adequate sea room for your (PDV)vessel's safe passage in the NC. 3. Assess the presence of ROC (Rule No. 7) by taking a compass bearing and observing whether the approaching vessel's bearing changes or remains consistent. 4. If the CBD has taken early action and provided sufficient sea room (likely indicated by a potential adjustment in speed (increasing or reducing speed) due to its restricted maneuverability): OPTION A: If the CBD accelerates (increasing speed) and can safely clear your bow while crossing the NC, you may pass astern of the CBD, maintaining a course as close to the starboard side outer limit of the NC as safe and practicable. Ensure compliance with the following rules: - Rule 8.(a): Execute actions with positivity, allowing ample time and observing good seamanship. - Rule 8.(b): Ensure actions are sufficiently large to be readily apparent by the CBD. - Rule 8.(d): Guarantee actions result in passing at a safe distance, and monitor their effectiveness until the CBD has passed and cleared. OPTION B: If the CBD reduces speed and allows you to pass before crossing the NC, you may increase your speed and continue to navigate within the Narrow Channel (NC). Ensure compliance with the following rules: - Rule 8.(a): Ensure actions are positive, allowing ample time and observing good seamanship. - Rule 8.(d): Guarantee actions result in passing at a safe distance, and monitor their effectiveness until the CBD has passed and cleared. Once the CBD is clear, you can adjust your speed back to a safe maneuvering speed (complying with Rule 6 - Safe Speed). FOLLOW-UP RULES TO APPLY WHEN ROC EXISTS: However, if you observe that the CBD, as mandated by Rule 9(d) and Rule 8(f)(i), fails to take early action and continues crossing the NC, resulting in the emergence of Risk of Collision (ROC), then you must take action and adhere to the following rules: 1. In accordance with Rule 8.(f).(iii), you (PDV) are still fully obligated to comply with Part B Rules when ROC exists during the approach with the CBD while she crosses the NC. 2. Remember Rule No. 3.(h), where the term CBD refers to a Power Driven Vessel (PDV). 3. As per Rules Part B, considering the types of vessels involved in this scenario (two PDVs and ROC existing), Rule 15 must be complied with. 4. Under Rule 15 (Crossing Situation), as you have a CBD, which is also a PDV, on your starboard bow, you must keep out of her way and avoid crossing ahead of her. Thus, you, as the PDV, become the Give-way vessel (to comply with Rule 16). Take early and substantial action to keep well clear, while the other CBD=PDV (on your starboard bow) becomes the Stand-on Vessel (to comply with Rule 17). She must not alter the course to port for you (PDV) on her own port side and may continue crossing the NC. YOUR ACTION TO AVOID COLLISION: Considerations: Since the other vessel crossing the NC (Narrow Channel) from starboard to port is a CBD=PDV with a special condition severely restricting her from deviating from her course, the most probable action for this CBD=PDV is to continue crossing the NC by increasing her speed. On the other hand, as per Rule 15 (Crossing situation), you as the PDV must keep out of the way of this CBD=PDV and avoid crossing ahead of her. You should pass the astern of the CBD=PDV by altering your course to starboard and maintaining a course as close to the starboard side outer limit of the NC as safe and practicable. Additionally, you may reduce speed to avoid collision or allow more time to assess the situation. When taking action to avoid collision, ensure compliance with the following rules: - Rule 8.(a): Execute actions positively, allowing ample time and observing good seamanship. - Rule 8.(e): Slacken your speed or take all the way off by stopping or reversing your means of propulsion. - Rule 8.(d): Ensure actions result in passing at a safe distance, and carefully monitor their effectiveness until the CBD=PDV has passed and cleared. Once the PDV has passed and cleared, you can increase your speed back to comply with Rule 6 - Safe Speed and continue navigating as close to the outer limit of the channel as safe and practicable. =================================================== Let me now address the second question outlined previously: Who assumes the role of the STAND ON vessel and who assumes the role of the GIVE WAY vessel in this particular scenario? Initially, In this scenario phase, when there is no Risk Of Collision (ROC) present, there are NO vessels designated as STAND ON or GIVE WAY. Rule 9(d) applies, placing the obligation on the CBD vessel not to cross the narrow channel (NC) in a manner that obstructs the passage of another vessel restricted to navigating within that channel or fairway. However, when ROC arises, as directed by Rule 8(f)(iii) to adhere to Part B rules, and as defined in Rule 3.(h), where CBD refers to a Power Driven Vessel (PDV), then based on the types of vessels involved, two PDVs are crossing so as to involve risk of collision, then the Rule 15 has to be complied with. Under Rule 15 (Crossing Situation), you have a CBD, which is also a PDV, on your starboard bow, you (as the PDV) shall keep out of the way of the CBD=PDV and avoid crossing ahead of her. Thus, in the event of ROC, you (PDV) become the GIVE-WAY vessel (to comply with Rule 16), to take early and substantial action to keep well clear. The other CBD=PDV (on your starboard bow) becomes the STAND-ON Vessel (to comply with Rule 17), Not to alter course to port for your (PDV) vessel on her own port side, allowing her to continue crossing the NC. I trust the above explanation clarifies your inquiries.

@@l-marineservices6749 thank you so much sir. 😇

@@PrathamIngle I'm delighted to address your inquiries. I eagerly anticipate receiving more questions and queries from you and your colleagues. Feel free to share with others as well.

Thank you for your comment. If you have any other queries on ROR, please ask.

Hi @fuufoo8833 - Yes I am, Especially Part A and B, you must memorize them. For the other part, understanding the concept would be sufficient. Part B - Steering and sailing rules have given sufficient guidelines for you to understand the obligation in each case, how to determine ROC, and how to take action to prevent Collision.
