Reliability of water-sealed conditions is crucial to the safety of water-sealed oil-storage. With a case study of underground water-sealed oil storage cavern in Huizhou, a reliability evaluation index system of water-sealed conditions is estabilished based on the main factors influencing water-sealed conditions. Also, a zonal evaluation of water-sealed conditions of the cave rock mass ranging from 0m to -70m is made by Fuzzy Analytical Hierarchy Process. Moreover, a three-dimensional numerical seepage model is established to study the seepage laws of the groundwater before and after the cavern excavation, and the water inflow during excavation and operation can be forecasted too. The results prove that the cavern site is suitable for the construction of large-scale underground oil storage caverns for its good water-sealed conditions and high reliability.

ABSTRACT Numerous above-ground and underground oil storage tanks and underground piping present a significant groundwater pollution threat when breached or deteriorated. The principal aid in cleaning up a spill on land or at sea is being able to observe it, and this opportunity is lacking in the case of the groundwater incident. A groundwater incident can be equally as damaging to the environment as a surface spill and can directly impact the public health by contaminating drinking water or creating hazardous atmospheres in cellars, storm drains, and sewers. In March 1991, when oil was found leaching from the bank of a river trench leading to the Cape Fear River, the Coast Guard Marine Safety Office (MSO) in Wilmington was able to control the oil in the trench through traditional use of booms and sorbents. The MSO was confronted with the threat of oil contaminating ground water and the challenge of locating the source. This report outlines the decisions, actions, and events surrounding the response to the groundwater contamination problem at the City Gas and Transmission facilty.

This is a case study of Aegean Marine Petroleum Network, Inc. (Aegean). Aegean’s founder and former CEO was the mastermind of several fraud schemes which pilfered $300 million from the company. During 2006-2018, Aegean’s Big 4 auditors, Deloitte and Price Waterhouse, failed to detect the fraud and issued clean, unqualified opinions year after year. After the fraud was discovered by Aegean’s audit committee in 2018, a group of Aegean’s stockholders filed a securities fraud lawsuit in New York City against the former CEO and the two auditors, and it will come to trial in the near future. U.S. Public Company Accounting Oversight Board (PCAOB) standards require an auditor to be professionally skeptical during an audit. He must maintain a questioning mind and make a critical objective assessment of audit evidence. In the Aegean case, the court held if the auditors had been more professionally skeptical, they may have been able to discover the massive fraud. PCAOB standards also require an auditor to search for related party transactions and to disclose them. In the Aegean case, the court noted it is inexcusable that the auditors were not aware that the former CEO owned Oil Tank, Inc., a firm which siphoned off millions of dollars from Aegean during the oil storage facility construction project. If they had been aware of this relationship, they might have been able to uncover the massive fraud. PCAOB standards also require an auditor to search for fraud. In the Aegean case, the former CEO engaged in several fraud schemes, yet the auditors were ignorant of them and issued unqualified audit opinions. This led the court to conclude that the auditors exhibited “willful blindness.”
