In January 2014, the program manager by NEN has invited Det Norske Veritas BV (DNV GL) to conduct a series of Hazard Identification (HAZID) sessions for LNG small scale facilities and activities. The HAZIDs played an integral role in identifying possible safety risks and failure scenarios that occur in the chain of small scale LNG supply.
Several scenarios for both trucks and ships have been reviewed for transport, fuel stations and bunkering. Even rail wagons and small scale liquefaction and bio-LNG were subjects in this study.
The final report gives 158 recommendations, some of them of very technical nature but some also more at organisational and societal level. It also tentatively suggests owners and responsible organizations for follow-up for the implementation process into e.g. existing/new guidelines, codes and regulations.
Part of the recommendations have immediately been used to set up the design of experiments for scheduled research work under the LNG Safety Program.
In line with one of the key recommendations of the HAZID sessions, NEN has set up in the Spring of 2015 a small taskforce with the aim to review to what extend the 158 recommendations made during the HAZID sessions in 2014, have been actually implemented.
The goals of the task force were to:
- check that originally proposed problem owners for all 158 HAZID recommendations are truly accepting their assignment together with the assigned priority both in terms of importance and in terms of urgency;
- provide an updated status of all 158 HAZID recommendations based on discussions with these problem owners (or new problem owners if original designee did not accept or was not capable otherwise);
- assess whether the recommendation is sufficiently addressed or need further follow up.
The task force concluded that:
- a total of 90 recommendations have been accepted by problem owners, either directly (70) or (partly) through other organizations (20);
- 60 recommendations were not accepted by the initially suggested problems owners, but alternatives were given for the majority of these (44);
- most recommendations (47) are assigned to the PGS 33 working group, which had its first kick-off meeting for the current revision process;
- 52 recommendations are considered to be sufficiently addressed;
- 96 recommendations still require further follow-up and 10 recommendations were identified as out of scope;
- follow-up has already started or is scheduled for many recommendations that require further follow-up.
Overall, it can be concluded that the HAZID recommendations (that were accepted by the problem owners) are given an appropriate level of importance and urgency.
