The minimum UKC as per this policy is 1.1m, so the vessel requires a minimum depth (Chart Datum + tide) of 11.8 + 1.1 = 12.9m. Calculating UKC.
What is dynamic Ukc?
Dynamic Under Keel Clearance UKC is the depth of water available underneath the vessel whilst it is underway, after allowing for the motions of the ship. DUKC® ensures every vessel has sufficient UKC for a safe transit, considering the environmental conditions during the voyage.
What is the formula of Ukc?
UKC is equal to the minimum total water depth at the location of the ship minus the maximum dynamic draft of the ship. The dynamic draft is the distance from the water’s surface to the lowest point on the ship’s keel while the ship is in motion.
What is static UKC?
Static UKC is the minimum clearance available between the deepest point on a vessel at rest in still water and the bottom. Static UKC = (Charted Depth of Water + Height of Tide) – (Static Deep Draft)
What is ship squat?
Squat is the reduction of a vessels Keel-Clearance, caused by the relative movement of the ship’s hull through the surrounding body of water. Compared with the neutral position (1) the hull sinks deeper into the water and at the same time will trim slightly.
What is difference between static and dynamic draft?
Static Draft is the Draft which is taken by the Transducer when the Ship is in Stationary. Dynamic Draft is the one which is taken when the Ship is Underway! As all of you said, static draft is when the ship is stationary and dynamic is when the ship is in motion.
What is the turning circle of a ship?
The circle is the path of the ship’s pivot point as it executes a 360° turn. In shallow water, the rate of turn is likely to be decreased, so the vessel will have a larger turning circle.
What is smelling the ground?
When a ship Nearing an extremely shallow depth of water, such as a shoal, she is likely to take a sudden sheer, first towards it and then violently away. This is called smelling the ground, and the movements of a sluggish ship may suddenly become astonishingly lively.
