Analasys of drilling platform Deepwater Horizon accident : master's thesis

Deepwater Horizon, bila je jedna od najmodernijih današnjih platformi, kao posljedica nekontrolirane erupcije iz bušotine Macondo 252 smještene u Meksičkom zaljevu zapalila se 20. travnja 2010. godine i dva dana nakon toga uslijed niza eksplozija teško oštećena i potonula. Osnovana istražna povjerenstva proglasila su kompanije odgovornim za akcident i definirala osam ključnih nalaza koji su neposredni uzrok dotoka u bušotinu, erupcije fluida na palubu platforme, zapaljenja plina i potonuća platforme. Ti nalazi odnose se na nedostatke u mehaničkim barijerama u bušotini, cijelom nizu loših odluka posade platforme i neispravnosti preventerskog sustava bušotine. Posljedica erupcije bušotine je potonuće platforme i jedanaest izgubljenih života, kao i više od trideset milijardi dolara što direktnih što indirektnih troškova za kompaniju British Petroleum. Bušenje u dubokom podmorju nakon havarije doživjelo je velike promjene. Postrožena je zakonska regalutiva i pojačane su inspekcije na platformama.Abstract: Deepwater Horizon, was one of the most modern platforms today, as a consequence of uncontrolled eruption from the Macondo 252 well located in Gulf of Mexico caught on fire on April 20th 2010 and after two days under series of explosions got heavily damaged and sank. Investigation teams that were formed have identified the company’s responsible for the accident and had defined eight key findings that were the cause of influx into the well, fluid eruption onto the platform's deck, gas ignition and platform sinkage. This key findings refer to defects on mechanical barriers in the well, a whole series of bad decision making from the platforms crew and malfunctioning blow out preventers. Consequences of the eruption and platform sinkage are eleven lost lives, over thirty billion dollars direct and indirect costs for British Petroleum. Deep sea drilling also went thru big changes. Legislation got stricter and platform inspections increased
