Installation and equipment for liquefied natural gas - Design of onshore installations

This European Standard gives guidelines for the design, construction and operation of all onshore liquefied natural gas (LNG) installations including those for the liquefaction, storage, vaporisation, transfer and handling of LNG.
This European Standard is valid for the following plant types:
   LNG export installations (plant), between the designated gas inlet boundary limit, and the ship manifold;
   LNG receiving installations (plant), between the ship manifold and the designated gas outlet boundary limit;
   peak-shaving plants, between designated gas inlet and outlet boundary limits.
A short description of each of these installations is given in Annex G.
Satellite plants are excluded from this European Standard. Satellite plants with storage capacity of less than 200 t are covered by EN 13645.

NOTE Natural gas condensates consist primarily of pentanes and heavier components, although quantities of propane and butane may be dissolved within the mixture 3.6 container - primary container container in continuous contact with LNG i.e.:  the cryogenic container of the single containment tank;  the cryogenic container of the spherical tank;  the inner cryogenic container of the double containment tank, full containment tank or cryogenic concrete tank;  the cryogenic membrane of the membrane tanks 3.7 container - secondary container container in contact with LNG only in the event of a failure of the primary container i.e.:  the bund walls for single and double containment tanks and spherical tanks;  the outer container of full containment tanks or cryogenic concrete tanks;  the concrete envelope of membrane tanks 3.8 conventional onshore LNG terminal LNG export or receiving terminal that is located on-shore and has a marine transfer facility for the loading or unloading of LNG carriers
NOTE The transfer facility is located in a harbour or other sheltered coastal location and consists of a fixed structure, or wharf, capable of withstanding the berthing loads of a fully laden LNG carrier of a given specification and mooring the vessel safely alongside. The structure is connected to the shore by a trestle, tunnel or other means, facilitating the LNG transfer and ancillary services and providing safe access and egress for personnel performing maintenance or operational duties 3.9 earthquake - OBE (Operating Basis Earthquake) maximum earthquake for which no damage is sustained and restart and safe operation can continue
NOTE This higher probability event would result in no commercial loss to the installation and public safety is assured 3.10 earthquake - SSE (Safe Shutdown Earthquake) maximum earthquake event for which the essential fail-safe functions and mechanisms are designed to be preserved.

1) Refer to European Directive [Council Directive 96/82/EC of 9 December 1996 on the control of major-accident hazards involving dangerous substances].

NOTE During the period of the year when gas demand is low, natural gas is liquefied and stored. LNG may be vaporised for short periods, when gas demand is high 3.22 LNG receiving terminal site where LNG carriers (ships) are unloaded, and where LNG is stored in tanks, vaporised and sent to the gas networks or gas consumers.
NOTE It has marine facilities for the transfer of LNG and can have loading stations for road, rail, barge or small LNG carriers 3.23 LNG satellite plant LNG satellite plants are connected to a gas network or gas consumers. LNG is supplied by road tankers, rail, barge or small LNG carriers. LNG is stored in insulated pressure vessels, vaporised and sent to the network 3.24 NGL (Natural Gas Liquid) liquid composed of light hydrocarbons (typically ethane through hexane plus) condensed from the natural gas prior to its liquefaction 3.25 normal operation operation including intermittent operation such as ship loading or unloading, start-up, maintenance, planned shutdown and commissioning 3.26 operator/occupier company responsible for the operation of the installation 3.27 owner company responsible for the safe design and construction of the installation 3.28 PASQUILL atmospheric stability factors PASQUILL atmospheric stability factors are determined as a function of the wind speed and solar radiation (see [1]). The six factors are:  A: extremely unstable;  B: moderately unstable;  C: lightly unstable;  D: neutral;  E: lightly stable;  F: moderately stable

NOTE The different types of tank are described in Annex H 3.36 transfer area area containing a piping system where flammable liquids or gases are introduced into or removed from the plant or where piping connections are connected or disconnected routinely 3.37 validated model mathematical model, the scientific basis of which is accepted to be sound and is proven to provide mathematical outputs to the relevant mathematical problem, and is shown to cover the full range of usage of the model and which has been calibrated or checked using realistic test data or results 4 Safety and environment 4.1 General The design, procurement, construction and operation phases should all be implemented in accordance with the requirements of the Quality, Health, Safety and Environment management systems as described in EN ISO 9000 and EN ISO 14000 series. Furthermore each phase shall be controlled by an acceptable Safety Management System.
2) Refer to European Directive [Council Directive 96/82/EC of 9 December 1996 on the control of major-accident hazards involving dangerous substances].

In-ground b c Scenarios to be considered: a In case of collapse of the tank primary container, fire pool size corresponds to the impounding area. b In case of collapse of the tank roof, the fire pool size corresponds to the secondary container. c Roof collapse is not considered for these tank types except if it is specified in risk analysis. d For definition see EN 14620 and Annex H.
b) Hazards which are not specific to LNG The following causes of hazards that are not specific to LNG shall be considered:  LPG and heavier hydrocarbon storage;  simultaneous loadings on multi-product jetty;  poor communication between ship and shore;  traffic within the plant both during construction and operation;  leakage of other hazardous substances, in particular flammable refrigerant;  missiles originating from explosion;  pressurised and steam raising equipment;  fired heaters and boilers;  rotating machinery;  utilities, catalysts and chemicals (fuel oil, lubricating oils, methanol etc.);  pollutants found in the feed gas of liquefaction plants;  electrical installations;
