Active RFID - The Case For Acceptance Of The IEEE Standard
Authors: Nabrotzky Ed 
Published: April 2016

Abstract

Objectives/Scope
Supply chain optimization is now an imperative for corporations, unfortunately existing track and trace functionality has not been previously available to cover the end to end supply chain. This is especially true in the Oil & Gas industry which is hampered by poor visibility of assets and equipment affected by onshore and offshore locations, large lay down yards and harsh environments. Historically, one of the greatest impediments to a complete solution has been the varied proprietary active tagging systems that do not allow for interoperability.

Methods, Procedures, Process
Unlike Passive RFID, which has been based on a universally accepted standard protocol, Active RFID has been based primarily on proprietary protocols. As a result, Active RFID systems have been highly expensive and inflexible. This has driven industry leading companies to express their support for an interoperability standard, similar to the EPC standard for passive RFID. The IEEE 802.15.4 standard, has risen to the top of that list. Specifically developed for active RFID, and based on Wi-Fi, this standard promotes interoperability for asset tracking using active RFID based tags and systems.
Driving the movement forward are new products such as the first (and only) intrinsically safe, dual technology tag – IEEE based active and passive RFID. This dual technology results in quickly locating the area of the asset as well as locating the specific item among a stack of like items.

Results, Observations, Conclusions
The acceptance of the IEEE 802.15.4 open standard for active RFID will encourage innovation and product interoperability that customers have been demanding and will ultimately benefit them by offering a choice of providers and thus eliminating licensing fees and legacy encumbrances, and unreliable technical performance. While end users will realize lower overall costs associated with implementing an active solution, manufacturers will benefit from the lower entry to market which will lead to the greater acceptance of active RFID across the marketplace.

Published: April 2016

The standardization process was initiated nearly a decade ago under a thriving scene of the oil industry. At that time, Petrobras had already had a long experience designing, contracting and participating in offshore production units. This vast experience showed that eventual optimization obtained with tailor made solutions tended to lose attractivity, regarding schedules and costs, when compared with identical projects. This perception motivated a movement towards standardization and a radical change in design philosophy. This initiative has proven to be applicable to a wide range of crudes and several units have been contracted since. The first standardized projects developed by Petrobras, were the P-58 and P-62 FPSOs, two similar units to operate at Baleia Azul and Roncador fields, respectively. These units are operating with very good results. Since then, eight "Replicants" were contracted to Brazilian shipyards and the first unit should be producing next year.
Despite the success of standardization, in current scenario of cost reduction, incrementing the capacity of new FPSO units is a major option to be evaluated. In this context, this paper will present Petrobras strategy towards EPC of its FPSOs and how cost reduction is planned. Future trends will also be discussed.
Analysing Scour Interaction Between Submarine Pipelines, Valve Stations And Mechanical Protection Structures

Published: April 2016

Subsea pipeline networks with components such as Wye-pieces and Pipeline End Manifolds (PLEMs) require protection from mechanical impacts. Pipeline scour is well understood and scour at solid caissons/gravity base foundations and piled foundations has been studied (Whitehouse, 1998; Whitehouse, et al., 2011; Sumer and Fredsøe, 2002). The scouring at small subsea gravity protection structures has received less attention than those with piles (Ottesen Hansen, 1997; Fog and Krogh, 2001) and hence there is uncertainty about predicting scour at such structures (Whitehouse, et al., 2010).
The design of subsea structures requires a composite assessment of scour and stability for the protected asset and the protection structure itself. A closed structure may lead to the formation of a scour footprint that is quite similar to a solid caisson or gravity base. For an open structure, the contribution to scour interaction from the different components is more difficult to assess.
Large-scale mobile bed laboratory experiments evaluated scour for a surface laid pipeline, with a spur and valves, and a generic subsea protection structure with mudmats and a perimeter skirt. Bathymetry mapping was achieved with a high precision underwater laser scanner. The experiments evaluated the contributions to scour arising from the different subsea components.
Sediment mobility was a key factor, with the perimeter skirt able to resist scour over part of its length when the mobility was low/moderate, whereas in a high mobility environment the skirt was completely undermined. The foundation beams were underscoured quite quickly and the eroded sediment was flushed out through the perforated mudmats, highlighting the importance of mudmat design. The scour pattern and rate was similar with or without the pipeline in place. The underscouring of the beams caused settlement and tilting of the structure, highlighting the importance of assessing scour and scour countermeasures for these types of structure. The scour assessment needs to be integrated into the structural, geotechnical and functional performance study for any structure and the new results illustrate the importance of understanding effects related to sediment mobility, the prevailing direction of currents, the design of mudmats and skirts, and the need for additional scour countermeasures.

Published: April 2016

Abstract
As Computational Fluid Dynamics (CFD) and High Performance Computing (HPC) technologies matured in many other industries, the offshore industry has begun to recognize CFD-based Numerical Wave Basin (NWB) as a design tool to evaluate offshore floater design more efficiently and with less uncertainty than the conventional ways relying on empirical methods. The recent NWB technology development has focused on the customization of CFD software for offshore design practices and validation of the developed analysis tools/procedures against physical model tests. Development has now extended to simulation of fully coupled hull-mooring-riser systems.
Technology readiness of the NWB for field application is demonstrated for two benchmark problems: Vortex-induced motion of a multi-column floaterGlobal performance of a multi-column floater in extreme wave environment
The results indicates that the CFD-based numerical wave basin, although still computationally expensive, is technically ready to be a complementary tool to physical wave basin for offshore platform global performance design.
Case Studies and Cost Savings Associated With Fit-For-Purpose Abandonment Systems
Authors: Olstad Delaney Michael 
Published: April 2016

Abstract
The development of innovative technologies and the effective application of late-stage intervention and abandonment systems in the oil and gas industry have resulted in cost savings and an increased standard of safety. This paper examines the successes of fit-for-purpose systems specifically designed for operations on load bearing offshore platform projects in an efficient manner.
To effectively address the market, a new system for completing interventions and abandonment operations was needed. Subsequently, a system was designed which incorporates capabilities associated with Jack Up rigs along with the quick mobilization and set up of a crane assisted rigless unit. This solution has been utilized in offshore campaigns that include all phases of abandonment operations including well diagnostics, reservoir isolation, tubular retrieval, fishing and section milling.
This paper will review the capabilities of the system along with case studies which highlight the versatility and adaptability of the system which provides an integrated solution package to the client. The system which includes a Pulling and Jacking unit also incorporates all ancillary equipment necessary to proficiently intervene and permanently abandon offshore wells. These case studies will discuss the planned parameters, examine the operations, and review the lessons learned from the projects.
Design and Installation of the Malampaya Depletion Compression Platform
Authors: Lorenti Leon , Grime Andrew , Raine Brian 
Published: April 2016

The Malampaya Depletion Compression Platform (DCP) was conceived by Shell Philippines Exploration B.V. (SPEX) to provide additional gas compression to account for the future expected decline in well pressure from the Malampaya field. The Malampaya project is very important to the ongoing prosperity of the Philippines, with the exported gas feeding three power stations which provide up to 45% of the power needs of Luzon, the largest and most populous island in the Philippines.
The DCP consists of a sealed barge structure which is rigidly connected to four cylindrical legs, each of which is supported on individual strut-linked hexagonal pad footings. The DCP arrangement uses cylindrical rather than truss legs and the base comprised a series of linked pad footings rather than a skirted baseplate. The leg configuration was selected in an attempt to simplify the leg fabrication; whilst the use of pad footings was a result of the site geotechnical conditions.
One of the key structural innovations on the project was to design a barge to leg connection which could accommodate both the required vertical movement of the circular leg during installation, as well as form a rigid moment connection at the final design level of the barge without excessive offshore works.
One of the key geotechnical innovations was to eliminate the need for a dedicated scour protection layer around the footings, yielding savings in procurement and offshore placement. This was achieved by selecting a foundation fill material capable of resisting self-scour in the 100-year return period cyclonic storm. The use of this larger sized material was agreed in advance with potential offshore Contractors to ensure that the required surface tolerances could be readily achieved.
Offshore work prior to the arrival of the DCP consisted of seabed excavation to remove the in-situ carbonate sand and reef limestone, and replacement with the engineered rock fill to form a sufficiently level surface for placement of each of the four pad footings.
Installation of the DCP at the Malampaya site commenced after a 3 day wet-tow from the fabrication yard in Subic Bay. Base lowering commenced on the morning of 12 February 2015, with touchdown occurring on the seabed some 26 hours later. Barge raising commenced immediately thereafter with the barge clearing the water around midday on 13 February 2015. Barge raising to the final elevation was completed in the early hours of 14 February 2015, less than 2 days after initial touchdown.
As well as providing a general overview, this paper will describe some of the geotechnical and structural innnovations which ensured a successful outcome of the project.

Published: April 2016

The oil industry has been negatively impacted by the fluctuating and declining commodity pricing trend. Many industry participants are preparing for a lower-for-longer price environment, with multiple delays and cancellations of Greenfield project developments. Longer-term, how will the industry energize deepwater developments to close the gap between cost and current commodity prices?
This manuscript is intended to provide basic background and to set the stage for a panel discussion scheduled for 2.00pm-4.30pm, Wednesday, May 4, 2016 at the conference. Panelists will discuss how breakeven deepwater oil costs have evolved to date and how they are managing development costs going forward. Some of the areas panelists will address are as follows:
Reducing supply chain costs
Using standardized or proven project designs
Improving upside potential by using third-party hosts for floating production systems
Forming alliances among service providers to enhance supply chain savings
Re-configuring fiscal terms and local content requirements with host governments
Is Johannes 1:1 ’n ‘raaisel’? Grammatikale getuienis
Authors: Van der Watt Jan 
Published: April 2016

Is Johannes 1:1 a ‘riddle’? Grammatical evidence. John 1:1 is one of the most famous opening lines in the Bible. No wonder that it received its proportionate attention in scholarship which is characterised by the differences of opinion regarding several issues addressed in these verses. It is suggested that these difficulties in interpreting this verse might be an implication that it is a riddle or at least has riddle-like qualities. The question to be dealt with further is whether the grammar, which is also subject of intense discussion, supports the idea that this verse might be a riddle.Keywords: John 1:1, Riddles in John, ‘God’ or ‘god’ in John, Johannine grammar

Published: April 2016

AbstractWe classify and analyze the orbits of the Kepler problemon surfaces of constant curvature (both positive and negative, 𝕊2and ℍ2, respectively) as functions of the angular momentum and the energy. Hill's regions are characterized, and the problem of time-collision is studied. We also regularize the problem in Cartesian and intrinsic coordinates, depending on the constant angular momentum, and we describe the orbits of the regularized vector field. The phase portraits both for 𝕊2and ℍ2are pointed out.
Mentale toestanden in de psychologie

Abstract

Mental states in psychology

Many of our thoughts, emotions and motivations have intentional content: they are ‘about’ something. In this paper I present my VENI research project, which starts from the observation that the everyday practice of empirical psychological research is built on the idea that mental states have content. However, empirical psychology lacks a clear view on how mental content should be understood and how mental states could be causally efficacious in virtue of their content. I focus on mental states that play a role in psychiatric symptomatology, and develop an interpretivist answer to these questions. I also offer some suggestions showing how an interpretivist notion of mental content could be used in empirical research on psychiatric symptoms.
Anachronistische waarden

Abstract

Anachronistic values

A value becomes anachronistic when it no longer fits current historical conditions (institutions, technology, culture, etc.). From an ‘idealist’ perspective, this fact does not tell against the old value (accepted as true), but rather against the new conditions. However, from a ‘naturalist’ perspective which takes values to be the product of human interests and (therefore) as interconnected with a given historical context, such a conflict seems to make a value obsolete. But this is neither an empirical law nor a normative rule. A defence of anachronistic values might still be perfectly reasonable. It is argued that such reasonableness depends mainly on three criteria: (un)certainty, scope and weight.
Wat maakt blind? Liefde? Of Wetenschap?

Abstract

Blindness in therapy? Love? Or science?

In this paper we dispute what seems an obvious truism these days: that increasing the influence of scientific research on psychotherapy is a good thing. We begin with an exploration of two distinct capacities that contribute in significant ways to human flourishing: knowledge and love. We then argue that modern society rather onesidedly capitalizes on the growth of scientific knowledge. This has an important drawback because the dominant model of growth presupposed in scientific research is built on the idea of reducing the potentially disturbing influence of the subjective engagement of the scientist with the object of knowledge. This is ordinarily quite a fruitful idea that has, however, paradoxically bad effects in evidence-based therapy. This is the case, we argue, because in a scientifically informed therapy the therapist should, in some sense, try to be blind to the effects of his expertise on his clients’ expectations of his expertise. A scientific, disengaged perspective therefore frustrates the therapist’s need to invest in the formation of a charitable relationship with his clients. Next we argue that the popular prejudice against love – that it is blind – is not as plausible as it is considered to be. To be sure, love invites cognition to accept a subservient role, but, we argue, this has some advantages too. It encourages the lover to discern particularly positive and promising features of the object of his love, and this, we argue, is crucial to a successful therapy in two ways. On the one hand, the therapist needs to engage with these positive and promising features to succeed in building the needed charitable relationship with his clients. And on the other hand clients often go into therapy because they lack access to their own positive and promising features and are therefore unable to entertain a charitable relationship with themselves. We conclude that with respect to psychotherapy there might be good reason for contemporary society to capitalize on the growth of love, rather than the growth of knowledge.
Liefde en persoonlijke identiteit

Abstract

Love and personal identity. Everyday loves, ambiguous selves

What we love matters for who we are. The idea may be self-evident, but how should it be understood exactly? One way is to conceptualize the formative influence of love on our identities in terms of ‘identification’: loving shapes who we are as we (volitionally) identify with the interests of the beloved and accept them as our own. Harry Frankfurt has fleshed out an influential identification-view along these lines. However, the identification-account is insufficiently able to accommodate the ambiguous nature of everyday loving and the way in which these ambiguities affect our identity. A second way in which the formative influence of love on our identity can be conceptualized is as ‘relation’: we are indeed shaped by what we love but the (affective-volitional) character of the relation in which we stand to our loved ones determines our identity. The latter view is capable to account for ambiguous loves and corresponding ambiguities in the self. Also, it gives prominence to the practical problem of loving, that is, to the question of how to relate to the people we love. It offers a more realistic perspective on that problem, as it takes the enduring differences between us and our beloveds into account, as well as the intersubjective character of loving. In sum: how we love what we love shapes who we are.
Schijnbare syntactische feniksen

Abstract

Apparent syntactic phoenixes

This article investigates ‘syntactic phoenixes’: obsolete or obsolescent constructions that unexpectedly regain currency in language use. Four case studies are investigated to gain insight in the reasons for the revival of these old constructions: (i) transparent free relatives, (ii) the complex preposition-like combination wat betreft, (iii) accusativus and nominativus cum infinitivo (ACI/NCI) and (iv) bare infinitive with the young modal hoeven. In all cases, the (temporary) reversal of the diachronic trends in the internal syntax of these constructions is argued to be driven by an analogical pull by cognate constructions. As such, the phoenixes are in fact illusions: the revival only affects a particular corner of the whole construction, namely where it borders on the neighbouring construction. The diachronic developments underscore the need to take into account the impact of the broad grammatical environment in which syntactic changes take place in grammaticalisation.
Downscaling future precipitation extremes to urban hydrology scales using a spatio-temporal Neyman–Scott weather generator

Published: April 2016

Abstract. Spatio-temporal precipitation is modelled for urban application at 1 h temporal resolution on a 2 km grid using a spatio-temporal Neyman–Scott rectangular pulses weather generator (WG). Precipitation time series used as input to the WG are obtained from a network of 60 tipping-bucket rain gauges irregularly placed in a 40 km  ×  60 km model domain. The WG simulates precipitation time series that are comparable to the observations with respect to extreme precipitation statistics. The WG is used for downscaling climate change signals from regional climate models (RCMs) with spatial resolutions of 25 and 8 km, respectively. Six different RCM simulation pairs are used to perturb the WG with climate change signals resulting in six very different perturbation schemes. All perturbed WGs result in more extreme precipitation at the sub-daily to multi-daily level and these extremes exhibit a much more realistic spatial pattern than what is observed in RCM precipitation output. The WG seems to correlate increased extreme intensities with an increased spatial extent of the extremes meaning that the climate-change-perturbed extremes have a larger spatial extent than those of the present climate. Overall, the WG produces robust results and is seen as a reliable procedure for downscaling RCM precipitation output for use in urban hydrology.
