O Intraduction
Each LNG port facm and terminai should have its
own specific safe@ systems determined by Hazard
compatible with these systems In general, for ail
vessels, particular care should be taken to ensure that
the basic requirements laid down in this standard are
understood and applied at each cargo transfer
In order to define the anangement which wiii ensure
the best possible conditions for ship to shore transfer,
in particular regarding safety, it is necessary to set up this standard which, as far as possible, wiii lead to the harmonbation of the differing requirements of the ship and the terminal
This standard governs the ship/shore interface taking
Intemationai Gas Tankers and Terminai Operatois
(OCIMF) and the Intemationai Maritime Organization
(MO) In particular, this applies in matters pertainkg
to safety
1 scope

h a z h
6.1 Description of LNG
The characteristics of LNG are described in EN 1160
The main hazards are defined in EN 1160 and those
most important in the transfer of LNG are:
- the cryogenic effects resuiting h m the very low temperatures These low temperatures can cause
injury to people (frost bite), and also cause damage
to noncryOgenc materials, which lose their mechanicai properties, become brittle and fr-acture;
- the potential hazards of ñre or explosion from
- the overpressure caused by rapid phase transition
o, due to the interaction between LNG and
-F
- overpressure due to thennai expansion of trapped
LNG

EN 1532 : 1997
The external hazards that should be considered in the transfer operations are:
1) natural environment:
- ahnospheric conditions (wind, lightning, etc.);
- sea conditiow,
- seismic conditions;
2) other hazards:
-jetty contact;
- collision with another ship or the jew,
- mooring lines breaking;
- fire at the terminal or its surroundings;
- LNG ship movement generated by the suction effects h m ships passing nearby
6 Hazardous areas
When the ship is moored at the jetty, the ship’s gas
dangerous space or zone is added to the jetty’s
(For deñnition of the ship’s gas dangerous space or zone, reference should be made to the IMO code:
Annex B: Reference 7.) The hazardous area on the terminai and jetty is
classzed in two types:
a) zone 1, for areas where the risk of an explosive atmosphere exists during n o d operation;
b) zone 2, for areas where an explosive atmosphere could occur in the event of deviation from nonnal operation
For definition of these hazardous areas, reference shail
be made to prEN 1127-1 and prEN 50145
Within the jetty area, the electrical equipment shaü be set out in accordance with EN 50014 to EN 50020,
EN 50028, EN 50039, EN 50054, EN 50056 to EN 50058
taking into account the zone where it is used and for non electrical equipment in accordance with
prEN 1127-1 The electrical equipment on the ship should be in accordance with the relevant Gas Code as
published by IMO
7 Safety precautions
Safety precautions may M e r from location to location
due to local conditions, therefore a hazard analysis
shall be carried out in each case to establish the
minimum safety precautions The hazard anaiysis shaìl
be performed according to prEN 1473 The basic
precautions as outüned in this European Standard are
considered to be the minimum safety precautions
hazard analysis for each terminai shali be considered
as exhri to the basic precaution The termiml and the ship shad always ensure that this minimum safety level
is maintained by the use of the ShipBhore Safety Check List (in this regard, reference should be made
to the SIGïTO guidelines Annex B Reference 6)
7.2 Basic precautions
7.2.1 Restricted harbour areas
In order to guard against unexpected collisions to the
LNG carrier when alongside, restricted areas around the berth for other maritime trat3.i~ shouid be defined
by the appropriate authorities and the terminai
7.2.2 Restricted area on the jettg
Areas in which the access of non authorized peisonnel
is limited should be regulated by the safety rules of the
terminai T h e e areas correspond, at least in part, to
the area affected by LNG transfer and should be clearly indicated
7.2.3 Restricted area on the ship
limited should be regdated by the safety rules of the
ship These areas correspond, at least in part, to the area affected by LNG transfer
7.2.4 Ship4shore sqfetu check list
The ShipBhore Safety Check List should be officially completed by ship and shore personnel before the start
of LNG transfer (In this regard, reference should be made to the SIGTIY) guideiines Annex B Reference 6.)
7.2.6 Moorim arrangements
The ship shall be safely moored in accordance with the regulations of the local appropriate authority and the tenninal (In this regard, reference shouid be made to
O BSI 1997
Copyright European Committee for Standardization
Provided by IHS under license with CEN
Trang 10```,-`-`,,`,,`,`,,` -Page 6
EN1632:1997
The mooring arrangements should suit the terminal
facility A s a minimum, the following points shall be
taken into account
- currenc
-wind
- surge due to passing shipq
-height of tides;
-waves and swell;
- change of freeboard
- variety of ships received
The winches or capstans on the jetty area shall be
suitable for operation according to the hazardous area
classification in which they are locaîd
The fenders shall be located so as to contact the hull
at the frame areas on the parallel body The fenders
should leave sufficient surface area to avoid damag@
the ship’s hull They shall not obscure the iniets and
outlets of the ship‘s circulation or ballast sea water
The ship should be moored safely and in a manner
which enables departure in the shortest possible time
The berth area shall be maintained at a suitable depth,
to ensure sufficient underkeel clearance at aii states of
the tide
7.2.6 Weather forecast
Weather foreass shall be available to the ship and
shore at intervals not exceeding 12 h
7.2.7 prurcipal sources czf ignition
Any risk of sparking in hazardous areas shall be
avoided
The choice of which protection measures to use in
electrical equipment is to be made according to the
existing local standards and according to the nature of
the hazardous area
There is a possible risk of sparking due to the
difference in e l d d potentiaì between the ship and
the jet& when the l w o a d i n g arms are b e i
connected or disconnected
Arrangements should be taken to avoid the risk of
sparking from this source through the inshhtion of an
indation fiange between ship and shore
7.2.8 Data tnuc8fer and communàcation
A means of transferring data shall be provided
between ship and shore When the ship is moored at
the jew, ESD information shall be txansmia by a
hard-wire data link
An orai communication system such as hand held
radios shall be providd It should have a separate
back up system which may be a land line telephone
7.2.9 Access
A minimum of two access ways between the ship and
the jetty should be provided
- one access, provided for personnel and crew, shall
be used for escape in the event of an emergency It
shall be located near to the ship’s accommodation
area;
- the second access, provided for operating personnel, should be located away from the immediate vicinity of the manifold area
7.2.10 Fire and leak detection
Leak and fire detection sensors should be insíalled in
ali hazardous areas as per recommendations in
prEN 1473 and shall be operational at all times The ESD resulting from fire and/or leak detection should
be transfeed to the ship as given in 7.2.8 The ESD
7.2.11 Fire protection
Measures shall be provided to protect personnel and essentiai equipment from a fire, both on shore and on
board ship, so that the risk of escaiation of an incident
isminimized
7.2.12 Firejightiw
There are four specific reasons for providing fire
@Ming equipment
a)toextlliguishasmallfiq
b) to safeguard people affected by a larger firq
c) to control a fire and to prevent it from spreading, pending the arrival of the Fïre Authonlx
d) to protect the means of access for the Fsre and Emergency Services
The extent of the fire fighting equipment supplied will
depend on a variety of factors and should be the subject of a hazard assessment by the temiinal The following items should be considered e) the causes and types of ñre that might be
e n c o u n t e e
f) the escape routes for ship and shore personnel;
g) the size, natwe and hquency of ships using the
te-
h) the size of the berths and of the ships and their
distance from other industrial hazards and
population centres;
i) the provision of ‘off site’ ñre fighting services
j) the time needed to mobilize the Fire Authonlx k) the emergency preparation and planning prOC€?dURS
including flre boats,
