ABSTRACTDue to exposed to the overheating temperature of about 600-700oC, the hardness of the wall tube (at C) was reduced to 129 HB compared to the original hardness of 137 HB. Acceptance criteria for hardness of A204 Gr. B carbon steel for the vessel is 143-187HB. It is similar to tensile strength of 70-80 Ksi. Reduction in the hardness was followed by reduction in tensile strength. Due to the reduction in the hardness and strength, the wall became bulging under two possible stresses; the weight load from the top structure and gas pressure on the inner surface of the vessel of cold collector. The effect of bulging caused reduction in wall thickness to 15.3 mm. However, acceptance criteria for wall thickness of A204 carbon steel for this vessel is 12.9 mm. The microstructure at the maximum bulging spot consists of normal ferrite matrix with first stage of carbide spheroidization as the result of the exposure to the high temperature. The carbide spheroidization presented along the grain boundaries. However, no creep cavity and microcracking observed and fit for further operation.

ABSTRACTThe structure of Reinforced Thermoplastic Pipe (RTP) is briefly discussed. By referring to international standard and real industrial application cases, the long time service limit of RTP is discussed with regard to temperature, pressure and water depth for offshore applications. The advantages of RTP with alternative solutions are the key to RTP solutions. The presentation will also include discussions on the future potential of RTP for offshore applications, in light of local industrial needs.

ABSTRACTOperating aging pipelines that have exceeded design life with the addition of SRB infestation present a major challenge to PCSB SKO. Microbially influenced corrosion (MIC) presents the largest threat to wet crude oil pipelines followed by acidic and other forms of internal corrosion. MIC has the highest corrosion rate with severe cases where pipeline useful lives were drastically reduced. Corrosion morphology of MIC appears as bottom-of-line localized corrosion that appears in wet crude pipelines with high SRB counts and H2S levels. These concentrated localized corrosion were able to be confirmed with in-line inspection data. Cleaning pigs with brush followed by biociding were used as primary mitigation. A holistic integrity management coupled with effective MIC assessment and mitigation strategies is essential for accurate remaining life assessment and extension.

ABSTRACTBiomass oil palm kernel shells are combined with HZSM-5 zeolite catalyst and made into binary fuel pellets for the purpose of reducing tar in gasification. The pelletisation of palm kernel shell with a catalyst constituent into a binary pellet has varying effects on the properties of the final densified product. During densification, the compaction properties of the formulation are strongly influenced by the characteristics of the mixture, in particular the particle size fractions of the components. The aim of this work was to study the mechanical strength of binary pellet made from palm kernel shell powder and HZSM-5 zeolite catalyst in the absence of binders so that the optimum strength can be achieved. The binary pellets were gasified to study its effectiveness in tar reduction. It was found that the pellet strength decreased with higher mass fraction of HZSM-5 zeolite in the binary pellet. Binary palm kernel shell and HZSM-5 zeolite pellets were found to be effective in reducing tar during gasification.

ABSTRACTCorrosion under insulation (CUI) is a form of threat of localized external corrosion for piping and equipment that has been insulated. The corrosion occurs when water penetrates through, absorbed and/or collected inside the insulation. Water ingress normally caused by (not limited to) poorly designed cladding, mechanical damage of cladding, or cladding not properly replaced. When water penetrates, it normally will tend to accumulate at low lying sections of piping or equipment. Corrosion begins as metal are exposed to both water and oxygen. CUI is promoted further with existence of free chlorides in certain type of insulation materials. Susceptibility of carbon steel to CUI increases with operating temperature ranging from 30 to 120°C.Currently there are various methods and strategies to inspect corrosion under insulation. One of the best ways to verify CUI is to strip the insulation for visual inspection, however this method is costly and time consuming. Portable Video X-ray provides alternatives to visual inspection without the need to strip the insulation materials. This provides option of quick assessment of the conditions of insulated piping or equipment. Further rectification work will be concentrated only to the affected area.

ABSTRACTWear is the main problem in gas turbine combustor components. The combustor components of a gas turbine had suffered severe wear damages after 8,000 Operating Hours (OH) in operation. Wear damage analysis by using visual observations, studies by optical microscopy, scanning electron microscope (SEM), coating analysis and wear size measurement has been carried out to identify the wear damage on the components. The mechanisms of wear damage occurred on combustor components can be fretting wear, adhesive wear or abrasive wear.

ABSTRACT Mature oil and gas fields give more sand production and management challenges. Sometimes these can constitute to major impediments to hydrocarbon production, optimisation, separator efficiency and general facility operation. Solids carry-over through the process facility can also cause flow assurance issues that will have an adverse impact on the system integrity, export lines, sand cleaning and disposal. Sand accumulation degrades production separator performance and conventionally has required shutdown for manual sand removal. This not only impacts on the operating cost but also increases the shutdown period. Solids production can also be a problem on some new wells especially without downhole sand control.nStork uniquely responded to these issues by developing an Advanced Online Desanding (AOD) system with the capability to remove solids from online vessel/separators without the need to shut-in wells or shutdown production. The AOD offers production, safety and financial advantages over the traditional vessel entry clean-out methods. This paper highlights key technical features and client benefits of the AOD system. Using North Sea case studies, it demonstrates how the AOD assists with optimising separator performance. The online desanding system has been successfully deployed in the United Kingdom Continental Shelf (UKCS) since 2006 and Offshore Angola in 2007.

ABSTRACTRheological properties of fluid have vital impact on heat transfer performance. Existing theoretical model on viscosity such as Einstein, Batchelor and Brinkman cannot accurately predict the viscosity of drag reducing nanofluid. Addition of drag reducing polymer additives (polyacrylamide) into nanofluid may alter the viscosity of the base fluid so it is important to carry out rheological studies to obtain synergetic interaction of both drag reducing polymer and nanofluid characteristics. This study aids in determining whether the power law model can accurately predict the viscosity of this drag reducing nanofluid. Rheometer AR 1500 will be used to measure the viscosity of the drag reducing nanofluid. The effect of shear rate, concentration on viscosity will be studied as a function of temperature. The viscosity measurement will be started at 250 and temperature is gradually increased to 750 at an interval of 100. Different concentrations of polyacrylamide ranging from 50 to 2000 ppm will be added to nanofluid ranging from 0% to 2.5%.
