Seabed features along a subsea pipeline route are highly stochastic. Free spans may be created in the pipelines due to seabed irregularities, subsequent scouring, and horizontal movements of pipeline during operation. It is quite common to encounter free spanning sections along the pipeline route from the very start till the end. Spanning of subsea pipelines is a primary area of concern not only in the detailed design and installation stage but also during the operation stage. For ensuring the pipeline safety during operation, underwater surveys must be conducted at suitable intervals. The frequency of such pipeline free spanning surveys depends on the operators' interest and the statutory requirements. The static and dynamic characteristic of the pipeline spans should be investigated to ensure that the pipeline can be operated within acceptable safety levels. The unsupported spans that incur static as well as dynamic loads on the pipeline, may lead to vortex-induced vibrations and ultimately fatigue, and thus affecting the pipeline serviceability and design life. Vortex induced vibrations are not allowed to occur in the operation life as far as the conventional design is considered but DNV - RP - F105 allows the onset of vortex induced vibrations provided that the fatigue damage due to vortex induced vibrations doesn't exceed the allowable values. Pipe soil interaction has a huge impact on the pipeline design as well as the pipeline service life. Analysis of the existing conditions and stress levels based on the site-specific surveys and environmental data needs to be carefully carried out for determining the acceptability of spans and the effective intervention works if required. Hydrological studies and numerical modeling may also need to be carried out for sediment transportation analysis and for proper assessment & quantification of sea bed erosion, trenching and backfilling requirements. In the present work, the acceptable criteria in terms of static and dynamic stresses and fatigue damage limits due to vortex induced vibrations as per DNV - RP - F105 have been discussed. Further comprehensive analysis philosophy and the criticalities in the design analysis for free spanning of subsea pipeline are presented. A case study based on an offshore project in western India has been presented involving the major project issues. The main areas of concerns & challenges faced are examined in detail. Further study has been conducted for the other available strategic solutions in the VIV mitigation and rectification of free spanning sections. Copyright © 2017 ASME.

This paper presents a case study of an underground crude oil storage project. This storage site is researched with detailed field and laboratory investigations. The layout, cross section, and elevation of the caverns are analyzed and designed based on geologicaland geotechnical information obtained during these investigations. In this study, two-dimensional (2D) elastoplastic analysis is performed using the finiteelement code Phase 2D to study the rock mass behavior caused by staged excavation of the cavern (20 mwide × 30m high). The excavation of the cavern is simulated with different stages, i.e., excavation ofa pilot tunnel and subsequent side slashing followed by excavation for a pilot bench and subsequent side slashing with a total of three benches. Displacement values obtained analytically are compared with the observed displacement as the excavation progresses. Because the2DFEMcode is based on the plain strain concept, it could not take into account the effect of excavation in other directions that is very obvious at the intersection with tunnels and shafts. Therefore, these intersections were analyzed using a linear three-dimensional (3D) boundary element code, Examine3D. The stability analysis of rock wedges formedfrom various joint patterns is also studied using the UNWEDGE software based on block theory for each section of the cavern. © 2012 AmericanSociety of Civil Engineers.

The present study reports the removal of oil from oil-in-water (o/w) emulsion using a commercial resin which is a co-polymer of styrene and di-vinyl benzene. The stability of the 0.05% (w/w) o/w emulsion was investigated for different surfactant concentrations (0.25-4%), mixing time (5-60min) and stirring rate (500-2500rpm). The emulsion stability was estimated by measuring the relative volume of emulsion after 24h of the preparation of emulsion and the zeta potential. 1% of surfactant, 18min of mixing time and 2000rpm stirring were found to be the optimum conditions for the most stable emulsions. A series of experiments were performed to investigate the effect of such parameters as influent oil concentration (30-500mg/dm3), bed height (30-100mm) and flow rate (10-20dm3/h) on the oil removal efficiency of the resin. More than 89% of emulsified oil was removed under optimal operating conditions: 10dm3/h flow velocity, 75mm bed height, and 500mg/dm3 influent concentration of oil in the o/w emulsion. SEM and FTIR results indicate that the hydrogen bonding and hydrophilic interaction were the principal driving forces for the adhesion of oil onto the polymeric resin surfaces. The results indicated that the resin is very effective in removing oil from o/w emulsion. © 2011 Elsevier B.V.

This study investigates the drained stress-strain-volume change behavior of Delhi silt under triaxial compression and extension loading conditions using two different existing constitutive models, the hardening soil (HS) model and a hierarchical single surface (HISS) model. The HISS model is shown to be able to capture the stress-strain-volumetric response in both compression and extension loadings with higher accuracy as compared with the HS model. © 2012 American Society of Civil Engineers.

A major fire incident took place in the Reactor Effluent Air Cooler (REAC) of the Hydrocracker Unit (HCU). The air cooler was severely affected. Cracks were observed on the welding joints between the top plate and the tube sheet, between the bottom plate and the tube sheet of the floating header. The material of construction of the air cooler is Duplex Stainless Steel (DSS). Visual inspection was carried out on the failed portion and its surrounding area. A systematic metallurgical investigation including mechanical testing, macrostructural and microstructural analysis, Scanning Electron Microscopy (SEM), and Energy Dispersive x-ray Spectroscopy (EDS) was conducted on the failed air cooler. The failure at the weld root and at the fusion line is attributed to crevice and pitting corrosion in the presence of the process fluid containing Chlorides, Hydrogen Chloride (HCl) and Ammonium Chloride (NH4Cl). The remaining portion of the weld exhibited characteristics of brittle failure. The failure is attributed to a combination of ductile fracture at the weld root and brittle fracture in the remaining portion of the weld caused by the very high pressure process fluid containing Chlorides, HCl and NH4Cl. © 2014 by NACE International.

Buffer storage of crude oil in large underground unlined rock caverns is one of the economical alternatives to ensure energy security of import dependent countries. Principle of storage essentially employs ground water pressure for containing the product within an unlined rock cavern. Initial site investigation campaign carried out involving geological, geophysical, geo-technical and hydro-geological investigations, establishes competency of rock formations in conjunction with ground water conditions for construction of unlined rock caverns. In such projects, engineering geology forms an important aspect not only during the initial feasibility stage of the project, but also in subsequent execution phase, wherein unlined rock caverns are built by conventional drill and blast technique. Design of underground structures exhibit lot of uncertainties in their basic approach and require an active and dynamic design intervention during construction progress. In this context predictive geological model is developed based on initial investigation results, which is continuously updated as the excavation progresses through stages of heading and benches. As part of this modeling exercise, critical segments of the caverns are identified as geological hotspot which undergoes additional stability analysis before excavation in order to take necessary counteractive steps. This approach based on pro-active construction methodology, helps to ensure preparedness to address the rock mechanical aspects of the identified segments, thus results in a reduced risk exposure. The study outlines, the process of identification and approach adopted to treat geological hotspots encountered during excavation for large underground rock caverns. © 2013, EJGE.

Most of the past theoretical works with the rotating ring disk electrode (RRDE) system have been restricted to situations where supporting electrolyte concentration is large enough so that the effects of migration of ionic species in the solution becomes negligible. In this work, effects of ionic migration have been investigated for a RRDE system by solving the differential equations describing mass transfer in presence of ionic migration using numerical technique. Two cases were considered for simulation, presence and absence of migration of ionic species. Results indicate that in presence of migration, collection efficiency of a RRDE system increases for all electrode geometries and concentration boundary layer thickness reduces. Results also indicate that collection efficiency is dependent on electrode geometries. The system chosen for simulation is copper sulfate solution of 0.1 (M) concentration with little supporting electrolyte. It is also noticed that migration effect remains important for supporting electrolyte concentration as high as 0.1 (M). Limiting current condition was assumed. © 2012 American Institute of Chemical Engineers (AIChE).
