4 General requirements
4.1 Components
The floating establishment shall consist of floating body, connecting bridge and anchorage.
Additionally, a ramp may be necessary. Additional requirements for components of floating landing
stages for cargo shipping are specified in Annex B.
4.2 Strength
The strength of the components of floating establishments shall be fixed taking into account the actions
described in Annex A.
The strength shall be tested as specified in 7.2.
4.3 Buoyancy and stability
4.3.1 General
In combination with the following proof of buoyancy and stability, for floating establishments the
actions in accordance with Annex A shall have a partial safety coefficient of γ = 1,0.
F
4.3.2 Intact stability
At maximum draught level,
— a freeboard of at least 0,15 m,
— a safety distance of at least 0,30 m, and
— a heeling angle of no more than 10°
shall be maintained.
In addition, the metacentric height for floating establishments under option A (see 4.4) under impacts
as per A.5 to A.7 and A.11 shall be at least 0,15 m. For these structures, heeling motions caused by the
vessel’s movement or by the mooring equipment as well as open areas of liquid, which occur during the
operation of the floating establishment, shall also be taken into consideration.
Intact stability shall be tested as specified in 7.3.1.
4.3.3 Damaged stability
It shall be ensured that the floating establishment will neither sink nor capsize in the case, that one air
chamber is damaged. In this case, a residual freeboard and a residual safety distance each of not less
than 10 cm shall be maintained; if greater residual safety distances or residual freeboards are required
by the specifics of the waterway, these shall be taken into account.
Free surfaces of liquids that can occur during operation shall also be taken into account.
If all buoyancy bodies are completely filled with a material according to 4.5.4, proof of leak stability may
be omitted.
Damage stability shall be tested as specified in 7.3.2.
4.4 Anchorages for floating establishments
Floating establishments shall be anchored in their positions to prevent them from being torn loose or
being displaced by currents, wind, waves, fluctuations in water level or the draught or wash of passing
vessels or possible special loads. In the case of floating landing stages, the influence of berthing ships
shall also be taken into consideration. The functioning capability of the anchoring of the floating
establishment shall also be proven for the case that the floating body of the floating establishment
springs a leak.
Anchorage for the floating establishment shall comply with one of the following two options:
a) option A: the floating establishment shall be secured to the land by means of:
1) chains;
2) steel wire ropes;
3) fibre ropes as per EN ISO 1140 or EN ISO 1346;
4) a pier anchor of appropriate strength and length; or
5) the connecting bridge.
The fastenings shall be secured against deliberate undoing. This requirement is met if it is not
possible to undo the fastenings without the use of a tool.
End connections of steel wire ropes shall be designed as splicers according to EN 13411-2 or by
means of aluminium ferrules according to ISO 8793. Textile slings of fibre ropes shall be designed
according to EN 1492-4;
b) option B: the floating establishment shall be attached to guides or dolphins in accordance with 4.5.3.
4.5 Structural requirements
4.5.1 General
The floating establishment shall be designed so that it can follow all changes in water level during
operation.
4.5.2 Freeboard
Taking into account 4.3, for floating landing stages the height difference between the traffic areas of the
floating body and the deck of the vessel shall be as small as possible for the berthing vessels expected.
For floating bridges the height of the traffic areas of the floating body shall be selected taking 4.3 into
account, so that no waves enter the traffic areas under predictable wind and wave conditions.
4.5.3 Floating bodies
Floating bodies using option B (see 4.4) anchorages shall be fixed so that they cannot twist. The height
of the guides or dolphins shall be sufficient dimensioned so that the floating body is not flooded at the
maximum water level to be expected or the floating body shall be secured against floating away.
Floating bodies shall have one or more buoyancy bodies, which
— comprise a total of at least three watertight air chambers or
— are completely filled with a material according to 4.5.4.
It shall be possible to seal the openings in the air chambers so that they are waterproof.
4.5.4 Materials for filled buoyancy bodies
Materials used to fill the filled buoyancy body shall have closed pores.
The water absorption characteristics of the material shall be taken into consideration during proving.
For buoyancy elements made of expanded polystyrene according to EN 13163, water absorption
characteristics according to EN ISO 16535 of a maximum of 5 % by volume are recommended.
These materials shall be resistant against external influences or protected against such influences.
5 Equipment
5.1 Railings, barrier
5.1.1 The traffic areas on floating landing stages shall be fitted with fixed railings as specified in
EN 711 at points where it is possible to fall into the water or to lower-lying levels when a vessel is
moored. The railings shall be of types PF, PG or PZ.
In areas provided for the berthing of vessels, the distance between the railings and the outer edge of the
floating landing stage shall be at least 0,70 m.
5.1.2 There shall be a barrier at the shore-side access point to the connecting bridge of the floating
landing stage if the design of the landing stage does not prevent persons being subjected to any hazards
when the vessel is going alongside.
5.1.3 Where a fall into the water or onto lower levels is possible, the traffic areas of floating bridges
shall be fitted with Type PF, PG or PZ fixed railings according to EN 711.
5.2 Life-saving equipment
5.2.1 The floating establishments shall have at least one plate with instructions for rescue,
resuscitation and first aid for drowning persons in accordance with EN ISO 18422 and at least
every 100 m one lifebuoy as specified in EN 14144 with a 30 m long floating line and holder as specified
in EN 14145 or housing according to ISO 18421.
5.2.2 Floating establishments with a height of the traffic areas above the water of more than 0,30 m
under dead load shall be equipped at least every 30 m with a permanently installed climbing device
according to EN 13574. The location of the climbing device shall be either at both ends on the
downstream side and/or alongside considering the flow conditions.
5.3 Device for mooring vessels
There shall be at least two bollards on the landing stage side of the floating landing stages. Each bollard
shall withstand at least a vessel mooring line force as specified in A.9. The tops of the bollards shall be of
non skid design and be permanently marked with signal paint.
5.4 Lighting
Lights attached to floating establishment shall not mislead or hinder shipping through dazzling effects
or reflections, nor give rise to confusion with waterway signs or impair their effect.
5.5 Electrical equipment
On the exposed deck, the electrical equipment shall have at least IP55 ingress protection code, in moist
rooms at least IP44 and for installation fittings for currents of 125A and greater at least IP66 according
to EN 60529.
5.6 Storage spaces
If the storing of loads which can influence the stability is foreseen on the deck of the floating body, this
shall be taken into consid
