7 Comparson of Exstng to ALCS Conventona Systems Some are ony avaabe to the partcpants n the regon (Operators) VERY heavy hard to transport and rg up offshore Best case for nterventon s 21 days key case s 40 days Very expensve Avaabty s frst-come-frst serve bass Controed by others ABEL LMRP Cappng System Avaabe to the rg qucky Onboard durng operatons (2x 20 foot contaners) Can be depoyed n tme t takes to pu rser pus 10 hours to nsta onto LMRP No need for 747 or AN-124 fts Cost s a fracton of the other systems Saves tme reduces exposure ABEL LMRP Cappng System 7

11 Abe LMRP Cappng System (ALCS) BASIC OPERATION Powered from pre-charged accumuators ROV operated Emergency dsconnect by ROV or acoustc sgna by hydra. ector DP dsconnect by on-off too Accumuators can be re-charged wth ROV Chemca njecton for hydrate breaker (f needed) Vsua read out of temp and pressure at crtca ponts Acoustc readout of pressure and temp ABEL LMRP Cappng System 11

13 Potenta Rsks of Another Incdent Damage to the vesse can be covered by Insurance Human tragedy can be covered n worker comp poces Envronmenta mpact max mt f avaabe s about 500m USD and s extremey expensve. (Loyds reuctant to ssue arge pocy mts post Macondo) Damage to the reservor not nsurabe absorbed by operator CONCLUSION o Sef nsured or at owner / operator s rsk o Macondo case: BP seekng $53b from Transocean n Haburton (receved $5b n settements). Governmenta fnes n bons. EXPOSURE IS HUGE and CANNOT BE MITIGATED WITH INSURANCE ALONE. ABEL LMRP Cappng System 13

14 Mtgaton of Rsks Means to mtgate pouton rsk: o Preventon - Don t et t happen n the frst pace - tranng of personne - adopt best practces o Contngency Pans and Equpment - tranng personne for cappng operatons - mnmze nterventon tme ne by havng contngency equpment avaabe at rgste.

15 Bowout Scenaro Most key next case We contro operatons occur Successfu dsconnect eaks (for whatever reason) MODU, LMRP are unharmed eaks cannot be stopped wth conventona technques DO NOT EXPECT Macondo to repeat wth same crcumstances ABEL LMRP Cappng System 15
