In­tel­li­gent cy­clone risk man­age­ment

The Australian Mining Review - - PILBARA PORTS -

SYS­TEMS En­gi­neer­ing Aus­tralia (SEA) re­cently launched its Engi­neers Aus­tralia award-win­ning, in­no­va­tive SEAtide storm tide and wind risk mod­el­ling soft­ware across Aus­tralia.

SEA prin­ci­pal Dr Bruce Harper, who worked as chief ocean en­gi­neer at Wood­side in the late 1980s, estab­lished SEA in 1996 to pro­vide quan­ti­ta­tive nat­u­ral haz­ards risk as­sess­ment ser­vices to the in­sur­ance in­dus­try.

From there, Dr Harper be­came a lead­ing in­ter­na­tional fig­ure in tropical cy­clone im­pacts, re­search and cli­mate change adap­ta­tion plan­ning.

SEAtide is a pre­dic­tion and anal­y­sis sys­tem that en­ables op­er­a­tions and emer­gency man­agers to rapidly eval­u­ate the pos­si­ble im­pact of storm tide threats to coastal fa­cil­i­ties and com­mu­ni­ties.

The sys­tem has been in op­er­a­tional use by the Bureau of Me­te­o­rol­ogy in the North­ern Ter­ri­tory since 2005, in QLD since 2014, and is now avail­able Aus­tralia-wide for in­dus­try and lo­cal Gov­ern­ment ap­pli­ca­tions.

With SEAtide, de­ci­sion mak­ers can rapidly ex­plore po­ten­tial im­pacts dur­ing emerg­ing cy­clone events, adopt spe­cific strate­gies around tol­er­a­ble risk avoid­ance, ex­am­ine his­tor­i­cally-pos­si­ble im­pacts at their leisure, pro­vide crit­i­cal staff train­ing and in­form strate­gic emer­gency plan­ning.

The sys­tem is es­pe­cially ef­fec­tive in re­gions with a high tidal range, such as the WA Pil­bara.

In ad­di­tion, SEA of­fers a wide range of spe­cialised nat­u­ral haz­ards risk ser­vices.
