End Date


Please be advised that the following navigation information is available: 
Wind gusts and thunderstorms are expected on 09/07/2024

Wind gusts are forecasted for this evening, offshore approximately 20 m/s and inshore approximately 25 m/s

Additional information regarding this warning:
• Please consult
• When gale force winds are expected (Beaufort 8), weather forecasts are being transmitted at 00.50, 01.50, 02.50, etc. on VHF channel 19 by the Harbour Coordination Center

Additional information for all vessels, all weather conditions, all berths: 
• Breast lines should be positioned as abeam as possible
• Spring lines should be positioned as parallel as possible
• All lines should have a minimum vertical angle
• All lines in the same service (e.g. all breast lines) should have same elasticity and same tension

Additional information for all vessels, adverse weather conditions, all berths: 
• Additional lines on winches to be deployed
• All winches to be in brake mode
• All thrusters to be in standby mode
• All anchors to be ready to let go
• Main Engine on short notice

Additional information for vessels with a large lateral service (e.g. container vessels), adverse weather conditions, at berths of Maasvlakte 1 and 2 (e.g. APM, ECT, RWG Euromax):
• Mooring equipment on board of vessels with a large lateral surface, according the standard building rules, do not keep vessels safely alongside under all conditions
• Maximum conditions under which the ship might pose to be a danger or cause hindrance to other ships or infrastructure:
 250 – 300 meter LOA: 22,2 meter / second (Beaufort 9)
 300 – 350 meter LOA: 18.2 meter / second (Beaufort 8)
 350 – 400 meter LOA: 15,3 meter / second (Beaufort 7)
• All wind speeds measured on board the vessel
• All wind directions perpendicular to the vessel’s side offshore or 45 degrees forward or aft
• According a report of a leading research institute: Royal Haskoning DHV
• Under such conditions the use of a minimum of two tugboats or two shore moorings as breast lines as additional measures is necessary to keep the vessel safely alongside
• These additional measures must be in place two hours before these conditions are expected
• If the vessel is not willing to use shore moorings or tugs the (State) Harbour Master can give an instruction (article 14.1 Rotterdam Port bye-laws) to the ship to leave her berth before the conditions are reached that will stop the ship from doing so safely, or will not be granted permission to come alongside
• If the weather conditions mentioned above have been reached before the vessel has departed her berth, and additional measures have not been ordered, then this is a violation of the Rotterdam Port bye-laws, and such measures will be arranged through the (State) Harbour Master on expense of the Master of the ship

Additional information about shore moorings:
Shore moorings in the port of Rotterdam (Shore Tension) exist of a mooring line, paid out to the vessel, with a Minimum Breaking Load of 200 Tons. This mooring line is tensioned ashore with a hydraulic device. Tension can be set up to 60 Tons, depending on the Safe Working Load of the bollards on deck of the vessel. The cylinder is certified by Lloyds Heaving Lifting Equipment up to 150 Tons. The Master of the vessel will always be in a position to monitor the forces on his or her vessel, and even gets an alarm if the forces are still getting too big – so there is sufficient notice to order additional tugs or shore moorings through the shipping lines’ agent.
Shore moorings are preferred, since the extended use of tug boats or thrusters may result in damages to the seabed and or quay wall structure. Above that, the availability of tug boats under before mentioned wind conditions may be insufficient.
