POV: WHAT IS STATIC UKC AND DYNAMIC UKC!

POV: WHAT IS STATIC UKC AND DYNAMIC UKC For safe navigation (especially in confined waters), mariners focus more on dynamic UKC because it reflects the real-time safety margin. In ship handling, UKC (Under Keel Clearance) is the distance between the ship’s keel and the seabed. There are two types: ⸻ ⚓ 1️⃣ Static UKC 🔹 Definition: Static UKC is the clearance when the vessel is not moving (at rest). 🔹 It considers: • Charted depth • Height of tide • Ship’s draft 🔹 Formula: \textbf{Static UKC = (Charted Depth + Height of Tide) − Ship’s Draft} 🔹 Characteristics: • Calculated before entering shallow water or port • Does NOT include ship motion effects • Used for passage planning ⸻ 🌊 2️⃣ Dynamic UKC 🔹 Definition: Dynamic UKC is the actual clearance when the vessel is moving. 🔹 It considers: • Static UKC • Squat effect • Heave, pitch, and roll • Wave response • Water density changes • Speed of the vessel 🔹 Formula (Simplified): \textbf{Dynamic UKC = Static UKC − Dynamic Factors} 🔹 Characteristics: • Changes continuously • Important in shallow water at speed • More critical than static UKC during navigation Thank you! #ConcernedProfessor #fyp #SEAMAN #fblifestyle #youtubeshorts #youtuber
