Drafts of vessels to and from Drogheda Port
To: Owners, Operators, Managers, Masters, Pilots, Agents and Stevedores
Attention is drawn to vessels Masters in loading their vessels of the need to allow for sufficient under keel clearance. Masters should take account of the effects of squat, increase of draft due to heeling, rolling or pitching and interaction when navigating in shallow water.
When planning the vessels voyage and in particular the arrival/departure drafts, consideration should be given to the tidal predictions and anticipated weather for Drogheda Port.
Masters are reminded that tidal predictions for any given tide may be affected by weather conditions, particularly high barometric pressure or a combination of wind and barometric pressure i.e., southerly winds and low barometric pressure may increased the tidal level above prediction, while northerly winds and high barometric pressure may reduce the tidal level below prediction. Storm events may also affect predicted depths.
In planning the voyage and in advance of arrival at Drogheda Port, Masters are also reminded to consult the appropriate nautical publications for tidal, berthing, e.t.a., and pilotage information (ref: Admiralty Publication NP 40, ALRS Volume 6(1), ALL Volume 'A', ATT Volume 1 (or similar). Additionally, Masters are reminded of the SafeSeasIreland (SSI) pre-arrival reporting requirements in respect of ISPS, polluting cargoes, hazardous cargoes and the landing of ship and cargo generated waste.
