Table 11 HAZID LNG Transit Route Segments

 

While the HAZID reviewed the LNG’s carriers approach with respect to distinctive sections of channel, the MQRA risk analysis will use the segment approach presented in Table I-2 in order to provide the results of the analysis over a consistent length (in this case 7.3 km segment length minimum, as required by HK Government, a length consistent with prior risk studies at Ma Wan)..

Note: Although the Sandia Report suggests that grounding events do not pose public risk and there have been no existing loss of containment for grounding, this report includes grounding events in the analysis.  The most credible scenario in the analysis was determined to be a small hole in the cargo tank (250mm) as the result of grounding event.

Note: The height of the fire plume is listed as a “fundamental assumption” in the Study Brief, section 3.7.9.4. This data is not an input assumption or parameter in SAFETI but instead is a data point generated as a result of the consequence modeling. The height of the fire plume, and the resulting radiation from it, is then considered in SAFETI when estimating the consequence impact and hazard to life in terms of individual risk and the EIAO FN curve.

A variable factor ranging from 0 (for bow-on collisions) to 0.65 (for beam-on collisions) was included in the release frequencies presented in the above tables to account for the exposure of the cargo tanks in the event of a collision.

BMT also performed an analysis to evaluate the risk of a passing vessel colliding with the carrier, while the carrier is at berth at Black Point or South Soko terminals.  It was determined that the frequency of an event at the Black Point berth was 2x10-8 and 4x10-8 per year in 2011 and 2021 respectively.  The frequency of impact at the South Soko berth was evaluated to be 1x10-17 and 2x10-17 per year in 2011 and 2021, respectively.
