"Dynamic Positioning Expert | Ensuring Safe DP Operations with ASOG & CAMO Systems 🚢⚙️"



ASOG (Airgap and Ship Operational Limitations) and CAMO (Continuous Airgap Monitoring) are two different systems used in Dynamic Positioning (DP) to monitor and manage the vertical position of a vessel, particularly in relation to its proximity to the seabed or other underwater structures. Both systems play essential roles in ensuring the safety and efficiency of DP operations, but they differ in their specific functionalities and applications.


ASOG (Airgap and Ship Operational Limitations): ASOG is a set of safety systems that are designed to provide real-time information about the vertical clearance between the vessel's hull and the seabed or other underwater structures. It monitors the airgap, which is the distance from the waterline to the lowest point of the vessel's hull, to ensure there is sufficient clearance to avoid collisions or grounding.

ASOG takes into account various operational limitations, such as the maximum allowed draft and the ship's geometry, to calculate the safe operational envelope for the vessel. If the vessel approaches the operational limits or if the airgap reduces to an unsafe level, ASOG triggers alarms and warnings to alert the DP operators. The system helps prevent potential accidents and provides vital information for the crew to make decisions during DP operations.

CAMO (Continuous Airgap Monitoring): CAMO, on the other hand, is a more advanced system that continuously monitors the airgap between the vessel's hull and the seabed in real-time. It uses various sensors, such as acoustic transducers or lasers, to measure the distance from the ship's hull to the seabed or underwater structures continuously.

CAMO not only provides real-time data about the vessel's airgap but also actively adjusts the DP system's position and heading to maintain a safe vertical clearance. It is capable of dynamically adjusting the vessel's position to avoid any obstructions or shallow areas, thereby enhancing the safety and efficiency of DP operations, especially in areas with varying seabed profiles.


In summary, ASOG is a set of safety systems that provides real-time information about the vertical clearance of the vessel, while CAMO is a more advanced system that continuously monitors the airgap and actively adjusts the DP system to maintain a safe clearance. Both systems are vital for safe and effective DP operations, especially in areas with potential underwater obstructions or varying seabed profiles.
