Florida real estate developer St. Joe Co. is suing Halliburton Co. over its role in the rig explosion that led to the massive oil spill in the Gulf of Mexico.

St. Joe said late Wednesday that Halliburton, which was responsible for encasing BP PLC’s subsea well in cement, ignored safety procedures and didn’t properly manage the cementing process. In deepwater drilling, cementing is a critical element in preventing oil and gas from escaping from the well.
