(d) ships of 10,000 tons gross tonnage and upwards, carrying liquified
gases in bulk.
These ships shall avoid the sea area between the mandatory route and
the adjacent Frisian Islands' coast, except when joining or leaving the route at the
nearest point of the route to the port of departure or destination which permits a safe
passage to or from that port.
The classes of ships referred to above shall use the mandatory route or
part of it:
(i) when sailing from North Hinder to the Baltic or to North Sea ports
of Norway, Sweden, Denmark, Germany or the Netherlands north of latitude 53°North and
vice versa;
(ii) when sailing between North Sea ports of the Netherlands and/or
Germany, except in cases of adjacent port areas;
(iii) when sailing between United Kingdom or Continental North Sea
ports south of 53°North and Scandinavian or Baltic ports; and
(iv) when sailing between North Hinder, United Kingdom or Continental
North Sea ports south of 53°North and offshore and shore-based oil-loading facilities in
the North Sea area.
These ships shall use the appropriate traffic lanes of the traffic
separation schemes forming part of the route, should follow the recommended direction of
traffic flow in the precautionary area (indicated by dashed open-outlined arrows in the
charts) and shall, as far as practicable, keep to the starboard side of the deep-water
routes forming part of the mandatory route.
Ships which, because of their draught, cannot safely navigate the
mandatory route - in particular the southern part of it (the routeing measures a, b and c
above) - are exempted from the requirement to use the southern part of the mandatory route
and are strongly recommended to use the western route of the routeing system "Off
Friesland" or part of it, as appropriate, instead.
This alternative western route is formed by the following routeing
measures:
.1 Deep-water route from North Hinder to Indefatigable Bank via DR1
lightbuoy;
.2 TSS "Off Botney Ground"; and
.3 Deep-water route from TSS "Botney Ground" to the
Precautionary Area "Friesland Junction".
Shipmasters should enter this deviation in the ships' log.
Joining or leaving the route
The classes of ships referred to above, when joining or leaving the
route:
(a) shall do so at the nearest point of the route to the port of
departure or destination which permits a safe passage to or from that port; and
