Abstract

Many of the oil and gas installations in the Indonesian Sea are reaching the end of their economic production life. Typically, oil and gas fields have an economic life of 20 to 40 years and a decommissioning program will be required and predicted to peak during the period 2010-2020. Some of them are located in shallow water such as those around Pulau Seribu, Java Sea, and South China Sea; some others are in deeper water such those at Makasar Straits and Moluccas Sea. Many different opinions exist on the benefits and problems of a partial platform removal or a complete removal. For some reasons platforms would be a good fishing spot. On the other hands, an unseen hazard could be left behind by the platforms. Even a complete removal of the platforms is conducted but without proper clearing of the ocean floor, the unused platforms still can cause hazards. For the management of the seas outside the territorial waters, worldwide nations have historically entered into international agreements and conventions. These agreements and conventions that have been entered into under the umbrella of the United Nations are Geneva Convention, the United Nations Convention on the Law of the Sea (UNCLOS) and the International Maritime Organization (IMO) Guidelines. Nationally, there is little information concerning with the decommissioning project. This paper is intended to highlight options for decommissioning of offshore platforms, its environmental impacts, and regulations that could be referred to following the decommissioning proposal. The technological aspects of the structural decommissioning of platforms are beyond the scope of this paper.

Abstract

The ratio of produced water to produced hydrocarbons increases over the lifetime of an oil well. It is common that oil well production fl uids in the old reservoirs are eventually composed of 90% or more of water and only 10% or less of hydrocarbons. After the initial separation of the bulk produced fl uids, the produced water still contains fi nely dispersed solids and hydrocarbons. It must either be re-injected underground or discharged to surface waters, such as oceans. Strict overboard discharge limits are set by the government regulation. The oil content of overboard water is limited by the Ministry of Environment to be less than 50 mg/L. Various chemicals have been developed as proprietary chemical separation aids to effect and accelerate the separation of oil, water, and solids from each other. These chemicals are commonly referred to as de-emulsifi ers and water clarifi ers. Other chemicals, for example corrosion inhibitors, have properties that are contradictory to de-emulsifi er and clarifi er. These non-separation aid chemicals will absolutely affect the fl uid (oil and water) separation. In the last couple of years, there were problems with the tar balls and chocolate mousse found in the coastal regions of Indonesia, such as at Pulau Seribu and Eastern Coast of Kalimantan. Although these tar balls do not frequently happen, these problems have given nuisance to the surrounding communities especially the fi shermen. This paper is intended to give an analysis of environmental view of the possible factors that might contribute to the formation of tar balls and chocolate mousse from the overboard water discharges from the old oil fi elds.

Abstract

ISO’s standards have been applied not only by the manufacturing industries but also universities as well as research institutions. Three ISO standards are commonly applied: ISO 9001, ISO 17025, and ISO 14001. Although these three standards have differences in the purpose, criteria, and emphasis, these standards can be applied side-by-side by an organization. Eventhough, many questions arise when the organization undertake more than one ISO. These questions, for examples, are: Is it not enough possessing just one ISO, for example ISO 9000 series only? What is the relation between one ISO to another? What is the relation between ISO and the existing regulations? Following the ISO system there is an internal affair in the institution that maintains and manages the quality system according to ISO, for example ISO 14000, environmental management standards. On the other hand, there is a research group in the institution that performs technical services for environmental laboratory testing and environmental research and studies. What are actually the difference functions between these two activities? This paper tries to conduct study in order to give answers for those particular questions. This paper is neither intended for describing ISO in details nor for tutorial purposes. Either comprehensive training or implementing ISO is conducted by a special authorized agency.

Abstract

The energy sector, including petroleum refining, is likely to feature in any legislation aimed at reducing CO2 emissions. It seems that petroleum refinery contributes relatively small amount of CO2 emission compared to other sectors such as transportations. Recently, through presidential speech in Copenhagen, government of Indonesia has committed to reduce CO2 emission to 26 percent in the year of 2020. Many technologies can be used for reducing CO2 emission in refinery. These technologies include fuel replacement, gasification of heavy residue which leads to single point CO2 capture, and CO2 equestration. This paper tries to discuss how far CO2 emissions contributed by refinery and possible actions that can be managed on the refinery to significantly reduce CO2 emissions
Isoprenoid Hydrocarbons As Fingerprints For Identification Of Spill Oils In Indonesian Marine Environment R Desrina

Abstract

Along with the increasing transport of crude oils to the refinery sites, many accidents of oil spills have been occurred in Indonesian waters. Such spills might be purely an accident but some others are suspected to be deliberately spilled. Nevertheless, both cases need an identification system to trace back the spill source and eventually the spill data can be brought to the court as an evident. Previously, the identification system was conducted through a pattern recognition of n-paraffin hydrocarbons of crude oil samples which are very distinguished from their gas chromatographic (GC) pattern of n-C17, Pristane, n-C18, Phytane, and other nparaffin’s down to n-C30. Unfortunately, some crude oils have similar pattern that matching of two chromatograms could give an ambiguity result. Pattern recognition of isoprenoid hydrocarbons have been developed to characterized crude oils that potentially pollute the Indonesian waters. Differing from the n-paraffin that each hydrocarbon peak can be determined definitely, the developed method does not need to identify each of the isoprenoid hydrocarbons, instead pattern of their chromatographic separation are sufficiently distinguished. GC isoprenoid pattern recognition is made from the isoprenoid peaks that emerge between n-C17 and n- 18. It two crude oils having similar pattern of n-paraffin’s show very distinct pattern of iso-paraffin’s. The method thus can be used as complimentary step in matching the GC pattern of crude oil samples . Although in some cases GC isoprenoid peaks are not completely separated, this would not be disadvantages since their retention time and area can be measured and integrated definitely, respectively. Nevertheless, the separation of iso-paraffin peaks can be easily conducted using a recent GC method namely a comprehensive two dimensional gas chromatography (GCxGC), a method which is recommended to be implemented further in this research.
