5 Graphic Design
5.1 General
5.1.1 The layout of the LNG port and jetty shall fully consider the influence of the natural
factors such as wind, wave, flow, sediment back-siltation on the navigation,
berthing/unberthing, loading/unloading operations of the ships.
5.1.2 Multiple LNG berths, LNG berth and LPG berth may be placed adjacent to each
other. The LNG carrier and LPG carrier may share the berth. When using the offshore
pier arrangement, the LNG berth and LPG berth may be separately arranged on both
sides of the platform; but the berthing and unberthing operation time shall be staggered.
5.1.3 The layout of the LNG port and jetty should consider the possibility of expansion;
and may consider the possibility of LNG carrier shipment, if required.
5.2 Waters on port and jetty
5.2.1 The stopping area of the sea harbor LNG carrier should be arranged in a straight
line according to the direction of entering the harbor. When the arrangement is difficult,
it may be arranged on a curve; however, the radius of curvature must not be less than
5 times of the design length of the ship. The stopping distance of the LNG carrier may
take 4~5 times of the design length of the ship.
5.2.2 The turning basin of the sea harbor LNG carrier shall be located at a place
convenient for the ship to enter and leave the harbor and berth/unberth the port and
jetty. The diameter of the turning circle of the turning basin should be less than 2.5
times of the design length of the ship. When the arrangement is difficult and the flow
rate is small, the diameter of the turning circle shall be less than 2 times of the design
length of the ship. For the harbor greatly affected by the water flow, the turning basin
may be arranged in an elliptical shape; the length along the direction of the water flow
may be increased to no less than 3 times of the design length of the ship.
5.2.3 The mooring basin in the front of the river harbor LNG port and jetty shall not
occupy the main channel. The width of the mooring basin in the front of the port and
jetty of the river reach with gentle water flow may take 2 times of the design width of
the ship; while it may take 2.5 times of the design width of the ship for the river reach
with rapid water flow. When the port and jetty is closer to the main channel, the width
of mooring basin in the front of the port and jetty shall be appropriately increased.
5.2.4 The turning basin of the river harbor LNG port and jetty should be located in a
place convenient for the ship to enter and leave the harbor, and berth/unberth the port
and jetty. The length of the turning basin in the direction of the water flow should be no
less than 2.5 times of the design length of the ship. When the flow rate is more than
1.5m/s, the length of the turning basin may be increased appropriately. The width
5.4 Port and Jetty
5.4.1 The scale of the port and jetty shall be determined according to the design scale
of the LNG carrier and calculation of natural conditions. The design ship type may be
determined through analysis and argumentation, but also may select the equivalent
levels of ships according to the current industry standard Design Code of General
Layout for Sea Ports (JTS 165).
5.4.2 The front-end top elevation of the LNG port and jetty shall be determined
according to the current industry standard Design Code of General Layout for Sea
Ports (JTS 165) or Code for Master Design of River Port Engineering (JTJ 212).
5.4.3 The design water depth of the front-end of sea harbor LNG port and jetty
shall be determined according to the safe stopping calculation of the full-load
designed ship at the local theoretically lowest tide level. The design water
depth of the front-end of the river harbor LNG port and jetty shall be determined
through ensuring the safe stopping calculation of the full-load designed ship at
the design low water level of the port and jetty.
5.4.4 Each rich depth in the calculation of the design water depth of the front-end of
the port and jetty shall be selected according to the current industry standard Design
Code of General Layout for Sea Ports (JTS 165) or Code for Master Design of River
Port Engineering (JTJ 212).
5.4.5 The length of the port and jetty shall meet the requirements of the ship for safe
berthing, unberthing and mooring operations; it is determined through simulation test,
but should be no less than double design length of the ship. In the feasibility study
phase, the 1.0~1.2 times of design length of the ship may be estimated.
5.4.6 Two dolphins should be provided for the pier LNG port and jetty; the center
distance between the two dolphins may take 25%~45% design length of the ship.
When the types of the stopping ships differ significantly, the auxiliary dolphin may be
provided, or the working platform also be used as the dolphin.
5.4.7 The mooring facilities of the LNG port and jetty should be arranged symmetrically.
5.4.8 The operating platform should be set up on the working platform of the large and
medium-sized LNG port and jetty. The layout and height of the operating platform shall
be determined according to the manifold location of the designed ship type; and shall
meet the safety operation requirements for the LNG carrier at the local maximum tidal
range and wave variation range.
5.4.9 The large and small LNG port and jetty should be equipped with boarding ladders.
5.4.10 The LNG port and jetty should be arranged workboat berths, or use the existing
workboat berths.
estimated as per the Formulas (5.5.2.-1) and (5.5.2-2), respectively.
5.5.5 When the water depth in front of the breakwater is large, and the waves are large;
the inside of the vertical breakwater should not be suitable for serving as LNG berth
also.
5.6 Access channel
5.6.1 When the LNG carrier navigates on the sea harbor access channel, the mobile
safety zone shall be set; the specific scale of the zone shall be determined through the
special argumentation. When the large-scale LNG carrier navigates on the sea harbor
access channel, it shall be traffic-controlled and equipped with escort ships. When the
medium and small-scale LNG carrier navigates on the sea harbor access channel,
whether the traffic-control is required shall be determined through special
argumentation.
5.6.2 The cargo tank of small inland river LNG carrier shall adopt Type-C independent
cargo tank; the ship’s side shall be designed with good anti-collision and shall conform
to the relevant provisions of related current shipbuilding regulation of China
Classification Society. When the small inland river LNG carrier navigates on the inland
river access channel, under the normal navigation state, the sound and light warning
shall be started. Under the fault state, the LNG carrier shall start the sound and light
warning; and guarantee there are no other irrelated ships get close within the range of
300mm of front-and-rear, and 100m of left-and-right. Under the condition that the cargo
tank is damaged and leaked, measures shall be taken within 1100m of around the LNG
carrier to prevent the irrelated ships and personnel to enter.
5.6.3 The navigation width of the sea harbor LNG carrier access channel shall include
track belt width, inter-ship richness width, and richness width between ship and the
bottom line of the channel. The navigation width of the LNG carrier single-lane channel
may be calculated as per the Formula (5.6.3-1). The navigation width of the channel
where the LNG carrier meets other ships may be calculated as per the Formula (5.6.3-
2). When the navigation channel is relatively long, the natural condition is relatively
complicated, and the ship locating is more difficult, it may be widened properly; when
the natural condition and navigation condition are favorable, it may be narrowed
properly through argumentation.
Where:
W – channel navigation width (m);
A – track belt width (m);
adjacent to the main channel, the special access channel may not be provided. The
access channel shall be provided for the main channel between dig-in basin and river
or lake zone. When arranging the port and jetty in the fork channel of the river, the
upstream and downstream fork channel of the port and jetty shall be designed
according to the access channel.
5.6.6 The scale design of the access channel of river harbor LNG port and jetty shall
conform to the relevant provisions of current national standard Navigation Standard of
Inland Waterway (GB 50139). The reference surface for the calculation of the design
water depth of the access channel shall take the designed lowest navigation level.
5.6.7 When the factors affecting the channel scale are complicated, the channel
navigation width shall be verified by the ship operation simulation test; if necessary,
the channel navigation width may be determined by combining the real ship
observation.
5.7 Anchor station
