PGS 33 represents a document from a long series of publications in the Netherlands related to production, transport, storage or use of hazardous substances. PGS 33 provides guidance for i) companies involved in these type of operations with LNG and ii) for the local and central authorities involved in granting licences, drawing up general rules and monitoring companies. Based on best available techniques, PGS 33 describes regulations, requirements, (design) criteria and other conditions that are to be used by companies that apply for an environmental permit in the Netherlands. In particular, safety regulations for labourers, external risk assessment, environmental safety, transport safety and emergency response features are described in an integrated though generic level.
PGS 33 has been produced and approved during 2013 using a team of experts from the industry, relevant authorities and emergency response organizations based on existing knowledge available at that time. Sometimes very conservative assumptions has been used to ensure safety under all conditions. The National LNG Safety Program has addressed in detail some of these (conservative) assumptions. The revision of PGS 33 is initiated early 2016 and the results of the LNG Safety Program will be reviewed and taken into account in the new version of the PGS 33 documents.
Note: PGS 33-1 specifically describes the situation at any land based LNG refuelling station, the PGS 33-2 document refers to bunker locations for ships along the waterways. It is intended to merge both parts to one document in the revision process.
