SAFETY SETTING ECDIS TOKYO KEIKI EC-8600 - Ship Channel

SAFETY SETTINGS ON ECDIS ARE VERY IMPORTANT TO AVOID SHIPS RUNNING AGAINST. There are four important safety settings on ECDIS: ~ Shallow Contour, ~ Safety Contour, ~ Safety Depth ~ Deep Contour. The contour is a line connecting equal depths and serves as a divider between shallow water and deeper water. The contour values ​​on ECDIS vary, such as 5, 8, 10, 12, 15, and so on, depending on the available depth in the installed ENC cell and the vessel's location at the time of inputting the safety settings. The Shallow Contour is a line dividing the sea area between a depth of 0 and the shallow contour value set by the ECDIS operator (Navigating Officer). Therefore, it is an area unnavigable by the user's vessel, referred to as unsafe water depth. This is depicted in blue or dark blue and indicates the depth at which the vessel will run aground, and is therefore considered a No Go Area (NGA). The Shallow Contour value must be entered equal to or greater than the maximum draft, or Draft plus the allowable Squat (Company Policy Squat). The Safety Contour is a safe limit for a ship to pass through and enter a safe depth area called the Deep Contour. However, the ship is between safe and unsafe waters. This is a concern for officers to avoid exceeding the shallow contour and causing the ship to run aground. Safety Contour Elements: ~ Draft ~ Squat ~ Minimum UKC Company Policy ~ Tide ~ CATZOC, ~ Rolling, ~ Pitcing, etc. The Deep Contour is the dividing line between the safety contour and the greater and deeper depths as input by the user. The Navigation Officer who makes these settings must fully understand this to avoid running the ship aground. For more details, see NP231 & NP232. We hope this video is helpful for novice officers. Thank you for watching. Greetings, Rob'Wild Capt. Persobi Waldemar.M #ShipChannel
