1) Identification of the operator and address of the facility
Liquefied natural gas regasification terminal in Świnoujście, hereinafter the LNG Terminal, is operated by Gaz-System S.A - Mszczonowska 4, 02-337 Warszawa, Mazowieckie province. LNG Terminal address: Ku Morzu 1, 72-602 Świnoujście.
2) Identification of the person providing the information by stating the person’s position.
3) Statement that the establishment is subject to the provisions on High Risk Facilities (ZDR) and that the Provincial Headquarters of the State Fire Service (KW PSP) received the ZDR notification
The LNG terminal is a complex of interconnected process installations, equipment and structures used for:
- receiving liquefied natural gas (LNG) from LNG ships (methane carriers),
- LNG storage,
- regasification of stored LNG and supply of natural gas to the gas transmission network,
- loading LNG into tanker trucks.
The LNG Terminal, due to the amount of LNG and natural gas contained in the process storage tanks and process installations, is subject to the legal provisions applicable to high risk facilities (ZDR).
Notification of the LNG Terminal as ZDR to the Provincial Headquarters of the State Fire Service and Provincial Environmental Protection Inspectorate in Szczecin was submitted on 4.11.2013.
In accordance with the ZDR regulations, the following have been developed and implemented at the LNG Terminal:
- Failure Prevention Program,
- Safety Report, which proves that the LNG Terminal fulfils the applicable safety standards and the multi-layered technical safeguards systems in place as well as procedural and organisational safety management system measures ensure that they are capable of preventing and limiting the consequences of potential failures to an acceptable risk level.
- Internal Operational and Rescue Plan describing rescue procedures to ensure readiness of the LNG Terminal to undertake rescue operations in case of emergency or failure.
These documents were, in accordance with the law, adopted and/or approved by the West Pomeranian Provincial Inspector of Environmental Protection and the West Pomeranian Provincial Chief of State Fire Service.
4) Description of the measures applied and the procedures to be followed in the event of an industrial accident
