Abstract

Offshore oil drilling creates impacts to marine ecosystem, not only to the lives in the water column but also tobenthic organisms. Coral reefs is one indicator that is prone to physical and chemical impacts of oil drilling. AJoint Operating Body, Pertamina-Medco E&P Tomori Sulawesi (JOB PTMS) has been operating since2005/2006 in the vicinity of Gusung Tiaka, Morowalu Utara, Central Sulawesi. JOB PTMS has a commitmentand responsibility to the sustainability coral reefs in the vicinity of drilling. Until recently, coral reefmanagement activities conducted were, coral reefs monitoring and restoring (using transplantation method) aswell as cleaning up from predator Acanthaster plancii. Coral reefs monitoring runs periodically in 2008-2014 in6 points of control. The coral reefs were in bad to good conditions, with mortality index 0.16-0.72 (scale 0-1).Coral reefs damaged was resulted from many factors namely, illegal fishing and predator Acanthaster planciiwith abundance of less than 30 individuals/hectare. Coral fish diversity index was 4,74-6.06. Coraltransplantation was moderate, not only the coral growth but also nekton (fish) recruitment with high number inthe vicinity of the transplantations. Coral reef management nearby drilling area has been running gradually, aswell as developing relevant programs with environment responsibility in the vicinity of Blok Tiaka, NorthMorowali
