Number: 33/2011

IJmuiden, August 10th 2011

Subject: Policy rules for transiting the North lock IJmuiden and North Sea Canal with marginal vessels

The director of the public body Central Nautical Management has, on the behalf of the hoofdingenieur-directeur of the dienst Noord-Holland of the Directoraat-Generaal Rijkswaterstaat, by the decree of August 10th 2011 (nr. 2011/129/CNB) altered policy rules for issuing dispensation for transiting the North lock IJmuiden and North Sea Canal with marginal vessels. These rules will come into force commencing September 1st 2011. 1. Legal framework: In accordance with article 9.02, 1st section, of the Inland Shipping Police Regulations and appendix 13 of these regulations listing the waterways on which this article must be applied, all vessels or compositions of vessels must conform to the stated mandatory maximum length, breadth and draft. The competent authority can, in accordance with article 9.02 2nd section of the Inland Shipping Police Regulations, grant dispensation to vessels exceeding the specified dimensions mentioned in appendix 13 of these regulations. 1.1 Maximum dimensions (without dispensation): To transit the North Lock at IJmuiden and the North Sea canal without dispensation, a vessel must not exceed the following maximum dimensions: Maximum breadth ≤42,0m; Maximum draft ≤13,10m (draft in saltwater, eastbound); Maximum draft ≤ 13,40m (draft in freshwater, westbound); Length overall ≤ 325,0m. While transiting the North Lock at IJmuiden all vessels without dispensation, must maintain a keel clearance of at least 1,0m. 1.2 Maximum dimensions (with dispensation): Marginal vessels transiting the North Lock and the North Sea canal are differentiated into several categories. These categories are: moulded breadth >42,0m and ≤45,0m; maximum draft >13,10m and ≤13,75m (draft in seawater, eastbound); maximum draft >13,40m and ≤14,05m (draft in fresh water, westbound); maximum length >325m and ≤350m.

1.3 Application for dispensation: The referred to dispensation must be applied two days (48 hours) before the intended transit of the marginal vessel through the North lock and North Sea Canal at the following adress: Port of Amsterdam Nautical Sector, Traffic management department attn.

Reason for adjusting the policy rules: 2.1 Redifinition vessel dimensions in the North Lock and North Sea Canal With the Ministry of Transport is agreed to promote uniformity, the vessel breadth as mentioned in the International Tonnage Certificate 1969 will be applied. 2.2 As a result of increased shipping dimensions, the maximum vessel length in the North lock becomes in reach. Therefore the category marginal vessels has been extended with a length category.

Date of coming into force of the policy rules: The policy rules come into force on September 1st 2011. The current rules as stated in Basijn 21/2006 will be cancelled on publication of this Basijn.

4 Maximum dimensions (with dispensation): Marginal vessels transiting the North lock and North Sea Canal are differentiated into five categories: These five categories are: I. moulded breadth ≤42,0m and draft >13,10m eastbound (§ 5); II. moulded breadth ≤42,0m and draft >13,40m westbound (§ 6); III. IV.

moulded breadth >42,0m eastbound (§ 7); moulded breadth >42,0m westbound (§ 8);

V.

maximum length >325m and ≤350,0m (§ 9). Although a number of similar conditions are set for some categories, it has been decided, for the sake of clarity, to publish the dispensation conditions for each category in full.
