Directive of the European Parliament and of the Council of 12 December 2006 laying down technical requirements for inland waterway vessels and repealing Council Directive 82/714/EEC (2006/87/EC) (repealed)

Article 10.01 Anchor equipment

1. Vessels intended for the carriage of goods, apart from ship-borne lighters whose length L does not exceed 40m, shall be equipped with bow anchors whose total mass P is obtained using the following formula:

• P = k · B · T (kg)

where

k

is a coefficient that takes account of the relationship between length L and beam B, and of the type of vessel:

for lighters, however, k = c will be taken;

c

is an empirical coefficient given in the following table:

Dead-weight tonnage in t	Coefficient c
up to 400 inclusive	45
from 400 to 650 inclusive	55
from 650 to 1 000 inclusive	65
more than 1 000	70

On vessels whose dead-weight tonnage is not greater than 400 t and which, owing to their design and intended purpose, are used only on predetermined short-haul sections, the inspection body may accept that only two-thirds of total mass P is required for the bow anchors.

2. Passenger vessels and vessels not intended for the carriage of goods, apart from pushers, shall be fitted with bow anchors whose total mass P is obtained using the following formula:

• P = k · B · T (kg)

where:

k

is the coefficient corresponding to paragraph 1, but where in order to obtain the value of the empirical coefficient (c) the water displacement in m³ entered in the Community certificate shall be taken instead of the deadweight tonnage.

3. Vessels referred to in paragraph 1 whose maximum length does not exceed 86 m shall be equipped with stern anchors whose total mass is equal to 25 % of mass P.

Vessels whose maximum length exceeds 86 m shall be equipped with stern anchors whose total mass is equal to 50 % of mass P calculated in accordance with paragraph 1 or 2.

Stern anchors are not required for:

(a) vessels for which the stern anchor mass will be less than 150 kg; in the case of vessels referred to in paragraph 1, final subparagraph, the reduced mass of the bow anchors shall be taken into account;

(b) lighters.

4. Vessels intended to propel rigid convoys which do not exceed 86 m in length shall be equipped with stern anchors whose total mass is equal to 25 % of maximum mass P calculated in accordance with paragraph1 for the formations (considered to be a nautical unit) permitted and entered in the Community certificate.

Vessels intended to propel rigid convoys which exceed 86 m in length downstream shall be equipped with stern anchors whose total mass is equal to 50 % of the maximum mass P calculated in accordance with paragraph 1 for the formations (considered to be a nautical unit) permitted and entered in the Community certificate.

5. The anchor masses established in accordance withparagraphs 1 to 4 may be reduced for certain special anchors.

6. The total mass P specified for bow anchors may be distributed between one or two anchors. It may be reduced by 15 % where the vessel is equipped with only a single bow anchor and the hawse pipe is located amidships.

The total mass required for stern anchors for pushers and vessels whose maximum length exceeds 86 m may be distributed between one or two anchors.

The mass of the lightest anchor shall not be less than 45 % of that total mass.

7. Cast iron anchors shall not be permitted.

8. On anchors their mass shall be indicated in characters which stand out in relief in a durable manner.

9. Anchors having a mass in excess of 50 kg shall be equipped with windlasses.

10. Each bow anchor chain shall have a minimum length of:

(a) 40 m for vessels not exceeding 30 m in length;

(b) 10 m longer than the vessel where this is more than 30 m and up to 50 m in length;

(c) 60 m where vessels are more than 50 m in length.

Each of the stern anchor chains shall be at least 40 m long. However, where vessels need to stop facing downstream they shall have stern anchor chains that are each at least 60 m in length.

11. The minimum tensile strength R of the anchor chains shall be calculated using the following formulae:

(a)

anchors having a mass up to 500 kg:

R = 0,35 · P' (kN);

(b)

anchors having a mass of more than 500 kg and not exceeding 2 000 kg:

;

(c)

anchors having a mass of more than 2 000 kg:

R = 0,25 · P' (kN).

where

P'

is the theoretical mass of each anchor determined in accordance with paragraphs 1 to 4 and 6.

The tensile strength of anchor chains shall be stated according to a standard in force in a Member State.

Where the anchors have a mass greater than that required by paragraphs 1 to 6, the tensile strength of the anchor chain shall be determined as a function of the actual anchor mass.

12. In cases where heavier anchors with correspondingly stronger anchor chains are aboard, only the minimum masses and minimum tensile strengths required according to paragraphs 1 to 6 and 11 shall be entered in the Community certificate.

13. Connecting pieces (swivels) between anchor and chain shall withstand a tensile load 20 % higher than the tensile strength of the corresponding chain.

14. The use of cables instead of anchor chains is permitted. The cables shall have the same tensile strength as that required for chains, but shall be 20 % longer.
