Küreselleşmeyle birlikte dünyada ve Türkiye'de
girişimciliğe verilen önem gün geçtikçe artmaktadır. Ekonomik kalkınmalarında en
önemli unsurlarından olan girişimciliğin arttırılması ülkelerin önem verdiği
bir konudur. Yüksek teknoloji üreten gelişmiş ülkeler kalkınmalarının önemli
bir kısmını girişimciliğe borçludur. Bireylerin doğuştan gelen girişimcilik
yeteneklerinin, önce aile desteği sonrasında ise devlet teşvikiyle ortaya
çıkarılması günümüz ekonomisinin elzem ihtiyaçlarından birisi haline gelmiştir.
Birçok gelişmekte olan ülke bireylerdeki girişimcilik potansiyelini ortaya
çıkarmak için çeşitli uygulamalar yürütmüştür. Bu uygulamaların en
önemlilerinden birisi de eğitimdir. Eğitim müfredatlarında girişimciliğe yer
verilmesiyle bireylerin girişimcilik yeteneklerinin ortaya çıkarılması ve girişimcilik
eğilimlerinin doğru yönlendirilmesi amaçlanmaktadır. Türkiye’de son yıllarda
nerdeyse tüm üniversitelerin tüm bölümlerinde girişimcilik dersi
üniversitelerin eğitim müfredatına eklenmiştir. Bu üniversitelerden biri olan
Kastamonu Üniversitesi Turizm Fakültesi öğrencileri aldıkları girişimcilik
dersleri ile potansiyel girişimci olarak düşünülmüş ve çalışmanın uygulaması
onlarla yapılmıştır. Bu çalışmada, öğrencilerin girişimcilik eğilimlerinin demografik
özelliklerine göre farklılıklarının saptanması amaçlanmıştır. Bu çalışmada Yılmaz ve Sünbül’ün geliştirmiş
oldukları ölçek kullanılmıştır. Çalışma
kapsamında 25 Aralık 2017-10 Ocak 2018
tarihleri arasında kolayda örnekleme yöntemi ile 585 öğrenci içinden belirlenen 461 öğrenci üzerinde yüz yüze
anket uygulanmış ve toplanan veriler SPSS programı kullanılarak analiz
edilmiştir. Yapılan analizler sonucunda Kastamonu Üniversitesi Turizm Fakültesi
öğrencilerinin, kararlılık, dışa açıklık, kendine güven, yenilikçilik ve
fırsatçılık faktörlerinde cinsiyetlerine göre anlamlı farklılık belirlenmiş ve
erkek öğrencilerin kız öğrencilere göre daha kararlı, dışa açık, kendine
güvenen, yenilikçi ve fırsatçı bir yapıya sahip olduğu sonucu ortaya çıkmıştır.
Ayrıca öğrencilerin sınıf seviyelerine göre risk alma, kendine güven, dışa
açıklık ve yenilikçilik faktörlerinde anlamlı bir farklılık bulunmuşken
kararlılık ve fırsatçılık faktörlerinde anlamlı bir farklılık olmadığı sonucuna
varılmıştır. Araştırmanın sonucuna göre erkek öğrencilerin girişimcilik
eğilimlerinin daha yüksek olduğu ve öğrencilerin yaşları ile eğitim düzeyleri
arttıkça girişimcilik eğilimlerinin de arttığı gözlenmiştir. Böylelikle girişimciliğin
öğretilebilir bir olgu olduğu, bireylerin olgunluklarının ve eğitim
seviyelerinin artmasıyla girişimcilik eğilimlerinin de artacağı sonucuna
ulaşılmıştır.

STRATEGIC PLANNING: SHAPING OR EMERGING FROM ORGANISATIONS
Authors: Sugiono Sugiono 
Published: April 2019

This paper focuses on the literature exploration of perspectives of strategic planning in terms of whether it shapes or emerges from organisations. The paper argues that to make judgment on an organisational performance as a result of planned strategies or emergent ones is not easy. Essentially, strategic planning aims to direct the performance of an organisation in order to attain its desired and planned goals. However, the organisation environment often changes rapidly, and hence it cannot be predicted and controlled. Such a circumstance potentially provides a particular impact on the organisation performance. In this situation, the strategic planning is inevitably shaped by the emergent strategy, which means that the realised strategy is the logical consequence of interactions between planned strategies and emergent ones. It has been suggested that a good strategic planning is to be flexible and open to a process of strategic learning, by which creativity and personnel’s commitment could be enhanced.

BackgroundStrong evidence on the long-term safety and efficacy of different types of anticoagulants would help clinicians to prevent thromboembolic events among patients with atrial fibrillation (AF) while minimising the risk of haemorrhages.AimTo estimate the risk of thromboembolic and haemorrhagic events for patients with AF on antiplatelets or anticoagulants.Design and settingThis was a cohort study using routinely collected UK primary and secondary care clinical data from patients with AF, aged ≥18 years, and with an indication to receive anticoagulation before April 2012.MethodThe risk of ischaemic stroke or transient ischaemic attack (TIA), coronary heart disease (CHD), peripheral artery disease (PAD), or gastrointestinal (GI) haemorrhage, between 1 April 2012 and 1 April 2017, was estimated using multivariate Cox regression models for patients on antiplatelets only, a combination of antiplatelets and vitamin K antagonists (VKAs), or novel oral anticoagulants (NOACs), and compared with those on VKAs only.ResultsCompared with VKAs, antiplatelets were associated with a higher risk of stroke or TIA, hazard ratio (HR) 1.51, 95% confidence interval (CI) = 1.09 to 2.09, and GI haemorrhage, HR 1.79, 95% CI = 1.01 to 3.18. The risk of thromboembolic and haemorrhagic events was similar for those on a combination of antiplatelets and VKAs, or those on VKAs only. The risk was also similar for those on NOACs or VKAs, except for CHD, where it was higher for patients on NOACs, HR 2.07, 95% CI = 1.35 to 3.19.ConclusionAnticoagulants are associated with lower risk of thromboembolic and haemorrhagic events among patients with AF than antiplatelets. More research is required on the risk associated with VKAs or NOACs.

STREAM JIP – Insights into Steel Catenary Riser Response Using Measured Data

Published: April 2019

Abstract
The objective of the STREAM (Steel Riser Enhanced Analytics using Measurements) JIP is to provide a measurement based foundation for SCR and lazy wave riser modelling to ensure that the fatigue response is assessed with adequate but not overly conservative parameters. To achieve this objective, the JIP utilizes field measurements from 4 in-service SCRs and 1 SLWR in water depths from 3,000 ft to 5,000 ft. The field measurements correspond to a range of environments including hurricanes and loop currents, riser functions, sizes, VIV suppression coverages and host vessels.
The processing commences with data QA, error assessment and data filtration. Riser response is categorized into wave dominated events, VIV events and others such as MIV events. As-built finite element riser models are developed and simulations are conducted using measured motions. The resulting analytical responses are compared with the measured motion and strain data to determine the level of conservatism or otherwise in typical riser wave fatigue analysis. SHEAR7 models driven by measured current profiles are used to compare predicted VIV response to observed VIV amplitudes and frequencies.
Analysis results indicate that industry standard fatigue assessment is indeed conservative. Sensitivities are conducted and presented on key design parameters that are known to be conservatively used in design such as hydrodynamic coefficients and SHEAR7 inputs. A set of parameters is derived that not only reduces fatigue damage bias but also improves the reliability in predictions. Recommendations are made with regards to further refinement of analysis parameters and understanding of atypical riser responses. Measured riser response that does not conform to typical wave and VIV spectra are presented and discussed.
The combined assessment of full scale field data from multiple catenary risers is an industry first. The results from this JIP offer valuable insight into riser response characterization with potential applications for SCR/SLWR life extension and more efficient new designs.
Note that in this paper, the term SCR is often used a generic term to describe both the regular SCR as well as the lazy wave implementation of it, the SLWR.
Fracture Mechanics Based Fatigue Assessment of an HPHT Valve Body
Authors: Sahoo Joshua , Campbell Mike , Cerkovnik Mark 
Published: April 2019

Abstract
The development of HPHT oilfield equipment has typically resulted in the construction of heavy-walled designs, where the increase in rated working pressure is accommodated by an increase in sectional thickness. This manner of design, however, is limited by practical difficulties which arise in the areas of manufacturing, handling/lifting, and uniformity of through-thickness material properties. Designs of more efficient size and weight may be developed by relaxing assumed design factors and hydrotest pressures, but this requires more rigorous analysis, validation, and QA measures.
In particular, designers must address the fatigue susceptibility of HPHT equipment which, even in purely static conditions, may fail under cycles of shut-in pressure alone. These failures typically originate from stress risers such as cross-bores, seat pockets, or transitions in bore diameter, which exhibit complex stress states under the action of internal pressure. A fracture mechanics (FM) based analysis of such features has presented a longstanding challenge to designers and analysts as general solutions for their KI and σref are not presently available.
It is therefore the objective of this paper to provide a useful methodology for conducting FM-based analysis of arbitrary geometry using the KI and σref solutions provided in API 579-1/ASME FFS-1. The method is presented in the form of a case study which describes the FM-based fatigue analysis of a seat pocket radius within a valve body. Here, the mode I behavior of a hypothetical surface-breaking, semi-elliptical flaw located at the seat pocket radius is evaluated by means of 3D finite element analysis.
This method generally comprises two parts. The first involves the development of a 3D finite element model similar to what would be used in a conventional durability analysis. From this model, stresses are extracted along an anticipated fracture plane and used in conjunction with a weight function method to derive KI and σref from solutions provided in API 579-1/ASME FFS-1. These solutions are then used to compute the number of cycles to unstable fracture.
The second part involves the direct incorporation of cracks into the finite element model. The approach benefits from a submodeling technique which reduces computational expense and allows the method to be used on complex structures. The numerical model is used in conjunction with conventional linear-elastic fracture mechanics assumptions to derive KI solutions for the geometry of interest. These KI results are used to confirm the conservatism of the code-based solutions and, thereby, the conservatism of the previous FM analysis.
The method described in this paper allows designers to rapidly develop and execute FM-based fatigue analyses of arbitrary geometric features in timeframes similar to those associated with traditional S-N analysis.
Ultra-Long Subsea Gas Condensate Tie Back – Pseudo Dry Gas – Liquid Handling System
Authors: Thomas Lee , Wood Terry , Pak Afshin , Liebana Laura , McLaurin David , Stokes Stephen 
Published: April 2019

AbstractThe Pseudo Dry Gas (PDG) technology / concept has been demonstrated for transporting wet gas in a long subsea tieback pipeline (200 km) in deep water depths (1.8 km) under wet gas conditions (water saturated gas) [Ref.1] along with a state of the art technology review of existing solutions. When a multiple of these in-line / piggable liquid removal units are used, they help to reduce the well back pressure by reducing the liquid content to an extent where ‘dry gas’ pressure losses are seen. Therefore, this mitigation of the gravitational pressure drop allows the use of larger pipelines to minimise the frictional pressure drop. This in turn increases recovery of reserves and allows tie back distances to be enhanced.The objective of this paper is to investigate a Pseudo Dry Gas System (PDGS) for an ultra-long deep-water gas condensate development, building upon the research and development already conducted with Strathclyde University. This work was undertaken using non-standard flow assurance methodologies and simulations recycling data and results with the advanced Computational Fluid Dynamics simulations of the liquid removal units behaviour, over various operational boundary conditions. Engagement with subsea equipment suppliers based on the flow assurance results has been undertaken. This paper describes how gas condensates within a subsea tieback system behave very differently to condensed water from a wet gas system and therefore a pseudo dry gas system needs to be configured differently for gas condensate developments. These differences include how and where the liquid drops out of the gas phase, where and if the free liquid is reabsorbed back into the gas stream and how the bubble point of condensate is equal to or very close to liquid removal units operating pressure; this greatly impacts the liquid handling system compared to a wet gas (water) design. Therefore, to ensure controlled liquid only transportation, careful examination of the liquid removal units performance, the liquid pump selection criteria and optimisation of the system needs to be undertaken. This results in a trade-off between maximum reserve recovery and system complexity.The paper demonstrates that the liquid condensate system will remain as a single liquid phase pipeline, where the number of pumps can be reduced and the pump power requirements are very low and within the existing technically qualified subsea pumps.
Heavy Wall Linepipe and Welding Solutions for HP/HT Pipelines
Authors: Jones Richard , Yamada Kenta 
Published: April 2019

Abstract
With the increasing drive towards high temperature/high pressure wells, particularly in deep water, riser designs are utilising increasingly heavier wall thickness pipe in conventional strength material, up to 50mm wall thickness in 8" and 10" OD X65 linepipe. In deep water, there is a cost preference to utilise steel catenary risers over other riser designs. Such riser designs are challenging existing seamless linepipe manufacturing and girth welding capabilities. Consequently, in order to establish confidence in the practical realisation of such riser designs there is a need to demonstrate: Adequate linepipe material weldability including the achievement of satisfactory HAZ, elevated temperature and sour service properties.Availability of cost effective girth welding solutions for pipeline fabrication.
Subsea 7 and Nippon Steel & Sumitomo Metal Corporation (NSSMC) collaborated on a development programme to qualify both linepipe material and welding solutions for the fabrication of pipelines of dimensions 273mm OD in both 35 and 45mm WT SMLS X65 linepipe.
The paper will demonstrate the technical feasibility of using heavy wall pipe for demanding riser applications installed subsea by the reel-lay method. The manufacture of seamless pipe in heavy wall thicknesses will be described together with the alloying and thermal treatment concepts involved. Details of the welding solution for pipeline fabrication will be reported together with the details of the scope and results of the qualification programme performed in support of reel-lay pipeline installation.

Abstract
Evaluation of corroded chain link for continued use or life extension is a challenging task for the industry. ABS, together with fifteen (15) participating organizations, initiated the Fatigue of Corroded Chains (FoCCs) Joint Industry Project (JIP) in 2016. The objective of the FoCCs JIP is to investigate methodologies for assessing remaining fatigue life of the corroded mooring chain used for floating production systems. The JIP scope includes fatigue testing in labs and finite element analysis (FEA) of corroded chain samples retrieved from six floating production facilities in West Africa and the North Sea. The participating organizations include oil majors, chain manufactures, consulting firms, and classification societies, which represent a pool of broad range of mooring knowledge and experience. Knowledge gained from the JIP will be summarized and used toward the development of guidance notes for assessing fatigue life of corroded mooring chain for the industry.
Six sets of mooring chain samples with different corrosion conditions have been collected, cleaned and digitally scanned for fatigue testing and FEA. Procedures for testing and analysis have been developed with the objective of establishing commonly accepted methods. Different FEA procedures have been studied for making a better prediction of stress ranges of the corroded chain links. The findings from the fatigue testing and FEA will be utilized as basis for further development of the methods for fatigue assessment of corroded mooring chain. This paper summarizes the tests and FE analysis work for the selected chain samples. The JIP research work has found that corrosion, either general corrosion or local/pitting corrosion, can significantly reduce the chain fatigue capacity. The location and the geometry of corrosion pits have more impact on fatigue lives than the pit size. The JIP study has shown that FE analysis is an effective tool to capture the hot spot of corroded chain links and can provide insight in their fatigue performance. Different methods on the assessment of the stress range of a hot spot are compared and discussed.
