Abstract
In the fiercely competitive realm of brownfield oil and gas projects, our well construction team embarked on a transformative journey marked by unparalleled achievements, as outlined in this paper. This abstract sheds light on the strategic fusion of cutting-edge technologies, innovative processes, and the skill and expertise of the well construction team, which drove the remarkable recovery of over one billion barrels of oil in the illustrious Bonga Field. Navigating the intricate challenges inherent in brownfield environments, our team pursued a dual path of technological innovation and operational process optimization. The tangible outcome was a comprehensive suite of groundbreaking drilling and completion advancements that accelerated project timelines, brought wells online sooner, and substantially reduced well capital and operational expenditure. The achievements are multifaceted, encompassing the adoption of pioneering drilling technologies for extended horizontal reach wells and real-time wellbore visualization using lookahead tools, particularly in geo-steering within thin-bedded sands. Advanced wellbore placement, trajectory control, and drill string optimization significantly elevated flow rates and rates of penetration (ROP), accompanied by improved cuttings cleanup.
A strategic paradigm shift involved using offset well data for risk assessment and well planning, eliminating the need for redundant activities in every well based on available offset well data. Operations were streamlined by integrating various tasks into single runs, showcasing unprecedented efficiency gains. Crucially, our focus transcended hardware enhancements to embrace strategic procedural improvements, with proficient drilling supervisors wielding optimized Bottom Hole Assembly (BHA) configurations to push operational boundaries and enhance ROP, ensuring wellbore integrity. The culmination of these achievements propelled the Bonga project well beyond its production target, recovering over one billion barrels of oil. This abstract immerses the reader in the strategic orchestration of technologies, procedural enhancements, and the exceptional prowess of our team, offering profound insights into the dynamic interplay between human expertise and cutting-edge solutions in the realm of well construction. It is a testament to the extraordinary accomplishments defining our journey to surpassing one billion barrels in the Bonga Field.
Novel Techniques to Improve Sea-States During 1st End PLET Initiation
Authors: Ravirala N. , Alshafei F. 
Published: April 2024

Abstract
1st End PLET initiation is a common method considered for offshore pipeline installation. The 1st End PLET helps in supporting a direct permanent hold back system without any other operations by secondary, vessels. However, there are some associated factors that limit the use of 1st End PLETs. These limiting factors include the complicated design and fabrication of a hinged system, the relatively large anchor forging loads and seabed features that limit the length of chain/wire length for initiation. These factors have a direct impact on the limiting sea-states for offshore installation which may result in long weather downtime.
Subsea7 has considered novel ideas to improve the sea-state for a scenario where the wire length has been restricted for a 1st end initiation PLET with a permanent hold back system. Subsea7 has investigated the use of a stretcher wire that has the capability of straining up to 25% at very high loads without compromising the structural integrity of the initiation wire system. The stretcher wire was connected between two chain/wire segments for a hinged 1st end PLET installation. It has also been considered for a Stab and Hinge PLET initiation method. In both scenarios, there is an improvement in the limiting sea-state compared to the case using an initiation wire/chain without the ability to stretch.
This innovative method using a stretcher wire provides a damping effect in the initiation wire system which is highly beneficial. This damping effect reduces the peak stresses and strains that typically occur at the anchor forging section of a 1st end PLET/pipe interface during initiation. Furthermore, the stretcher wire does not have any limitation to use under any external hydrodynamic pressure. Hence, this selection could be beneficial for subsea operations at any water depth.
This paper will discuss and analyze the installation methods used and the screening for a suitable stretcher wire for given 1st end PLET initiation. The limitations and drawbacks that should be accounted before considering the use of stretcher wire for initiation will also be discussed.
Subsea7 has successfully installed a number of 1st end PLETs with such a stretcher wire. Some of these projects will be listed here. Finally, this paper will also introduce potential future developments that are being considered to further improve the PLET initiation sea-state by further dampening the 1st end PLET system.
Wandoo A – Reliability Methodology for Determination of Probability of Failure of a Braced Caisson Structure
Authors: Roberts R. , O’Brien C. , Sheppard R. , Moslehy Y. , Kitson M. 
Published: April 2024

The Wandoo A (WNA) fixed platform was installed in 1993 with an intended service life of 15 years. It has subsequently undergone two 5-year life extension (recertification) studies – one in 2008 and another in 2013. The original design and both recertification studies followed API RP 2A WSD guidance (American Petroleum Institute, 2002).
The platform (see Fig. 1) is a braced caisson structure in 52m water depth. The structure supports five conductors: 1 through the main column, 2 external that penetrate through the skirt piles, 1 supported by an external riser caisson and 1 external. The foundation consists of five piles: 1 through the main column, 2 skirt piles, and 2 outrigger piles.
The system also features a tuned liquid damper (TLD) incorporated into the main column near El. (+)17m. This damper is intended to increase the structural damping and reduce system accelerations in response to environmental loading. The TLD is a set of three tanks filled to specific levels with water. The motion of the entrapped fluid provides the damping which has been tuned to the primary structural period.

Authors: Hammond G. , Ferrari S. 
Published: April 2024

Abstract
A new digital solution to manage access, hosting, distribution, and analytics of subsea data. UTEC, a Geo-services brand in Acteon's Data and Robotics division, has launched "iSite Subsea", a game-changing, cloud-based platform giving users an intuitive interactive delivery portal for survey and inspection data, designed specifically to meet the needs of the offshore renewable energy market, and oil and gas subsea infrastructure owners.
For infrastructure owners looking to consolidate key geo-referenced survey and inspection information, iSite Subsea interfaces seamlessly with existing databases, resulting in long-term cost savings.
iSite Subsea helps to reduce costs, lower risk, enhance health and safety, and deliver better informed decisions. The new platform facilitates the digital delivery, throughout the lifecycle of an installation, of geophysical, geotechnical, structural integrity monitoring, inspection, and maintenance surveys, providing owners, developers, and contractors access to the data they need to plan, evaluate and solve safety, environmental and risk scenarios.
Challenges that iSite Subsea solves include: lack of access to data sources because they are held in different systemsthe struggle to ingest and make sense of the large volumes of complex datadecision-making based on experience and gut instinct rather than reliable metricsthe requirement for disparate, tailored databases and analysis tools.
These challenges are addressed through an interactive graphical visualisation, enhanced with "critical" data, as a powerful tool to drive informed decisions. The intuitive interface layers information and enables comparisons between data sets; a vital capability, particularly for repeat events such as inspections and maintenance.
Floating Substations Joint Industry Project

Published: April 2024

Abstract
DNV and 38 project partners have been working together in a Joint Industry Project (JIP) to identify, understand and tackle the challenges involved in taking the step from bottom-fixed to floating substations. A floating substation will be critical for many projects, to bring clean energy from floating offshore wind farms to the market and consumers. A floating substation is also a meeting point between different disciplines and stakeholders. The JIP involves a broad selection of the value chain representing this meeting point. The group includes both HV component and dynamic cable vendors, engineering companies, designers and yards and not the least companies that will operate and own; Developers and Transmission System Operators.
The objectives of the Floating Substations Joint Industry Project are to: (i) Identify technology gaps and the development and qualification efforts required close these gaps (ii) Identify gaps in standards and (iii) Establish joint understanding and alignment of best industry practice and technical requirements for design, construction, and operation of offshore floating substations. To meet these objectives, the project has defined a design basis, performed gap analyses, technology assessments and failure mode analyses for the key parts of floating substations. Both HVAC and HVDC systems have been addressed. Floater motion analyses and dynamic cable feasibility analyses have been performed and compared for suitability for carrying the HV equipment. Key questions to be answered include (i) what is the right safety level for design of a substation (or: what failure probability per year is acceptable) (ii) what are the motion characteristics of a substation and how does this compare to what the topside HV equipment can tolerate (iii) how can we qualify feasible export system designs. The project has undertaken defined activities to find answers to these questions.
The ultimate goal of the project has been to develop sufficient knowledge and cross-industry understanding to make floating substations a reality with an acceptable level of commercial, technical and HSE risk. The knowledge developed through the JIP will form basis for design standards for floating substations and dynamic cables. In this presentation, DNV will give an overview of the project results, the plans ahead for standard integration and required next steps.
A State-Of-Art Study on Solution to Liquid Hold-Up and Back-Pressure Management in Long Tieback Deepwater Gas Pipeline Network in Indian Offshore

Published: April 2024

Abstract
Deepwater long tie back subsea gas pipelines poses a critical operational challenge with declining pressure and production over the field life, the problem will further aggravate if early water breakthrough encountered. The pipeline networks exposed to such a low producing early water cut fields for long period of time will lead to accumulation of high liquid resulting in creation of additional backpressure which affect the well deliverability. The increase in water production in gas wells were started to cause unstable flow in one of the complex Deepwater (1300m) dual 14"x58 km subsea (with U loop) to shore network from Eastern offshore of India due to liquid loading, making flow assurance a challenge to daily operations.
An innovative liquid management strategy has been developed through extensive analysis and devised the methodology by Flow Assurance team in association with an integrated Operations team, in order to address the liquid loading issues by effectively utilizing the limited available resources and surface handling facilities. Continuous monitoring and dynamic simulation tools have helped to understand flow stability in the subsea network for minimizing liquid holdup which have significantly reduced the back pressure and resulted in enhanced production. An integrated dynamic multiphase flow model used to optimize operating philosophy after validation with field parameters and accounted for the uncertainty of the associated controlling parameters, and accordingly devised the sequence of steps for dynamic pigging to minimize liquid holdup. The sequential methodology comprises of reduction of operating pressure at process end for partial liquid knockout; optimized diversion of selective wells to maintain the hydrodynamic slugging within handling limit; flowing all wells via U loop to knock out rest of the liquid to the possible extent.
Successfully mitigated the issue by effective implementation of innovative strategy which proved to be highly efficient in maintaining production in a sustainable mannerly minimizing the liquid holdup and significant back pressure reduction.
This paper presents the details of the innovative methodology, devised and successfully implemented using state-of-the-art dynamic simulation tools. These steps were proved to be effective in field without need of any additional operational/capital cost in safe operating conditions. The framework presented here can be applied to any similar deepwater field with subsea long tie-back. This model is a handy tool not only for engineering simulation but for operator training and real-time surveillance as well.

Mediações e Enfrentamentos: desafios do processo de criação em arte
Authors: . Editores 
Published: April 2024

A Revista Farol é uma publicação semestral vinculada ao Programa de Pós-Graduação em Artes da Universidade Federal do Espírito Santo. Como periódico da área de Artes, propõe-se como um espaço complementar de disseminação da produção teórica sobre arte moderna e contemporânea. Neste seu décimo segundo número, ela se dedica a reflexões sobre as mediações e enfrentamentos do processo de criação nas artes. Através das ideias de mediação e enfrentamento, este número apresenta aproximações, dúvidas, atritos e ruídos observados em variadas pesquisas e realizações da arte e de suas teorizações mais recentes. A velocidade com que surgem aparatos mediadores en-tre o sujeito e a realidade parece não desacelerar. Ao observar situações em que tanto o humano quanto seus ambientes culturais se estendem e se ampliam, o debate sobre o que há entre o criador e o mundo em que surge a criação torna-se premente.
Colaboração e Autoria: reflexões sobre o projeto de arte colaborativa na praça
Authors: Rampin Priscila 
Published: April 2024

O artigo visa discutir a noção de autoria em práticas artísticas que se moldam nos preceitos da participação e colaboração com base na análise do projeto Plante na Praça, proposto pela artista Andressa Boel e em andamento na Praça Said Chacur em Uberlândia (MG). Defendo a ideia de que a autoria nos projetos de arte colaborativa não os descaracteriza como tal; antes, a colaboração autêntica depende mais das circunstâncias do desenvolvimento desses projetos do que de uma geração espontânea. Assim, procuro elencar as características das quais o Plante na Praça — a meu ver — rapidamente se tornou uma ação dos moradores do entorno, dissipando a autoria centralizada na figura da artista.
Cadernos de Notas (des) folhamentos de tempo
Authors: França Cláudia 
Published: April 2024

Discutimos o caderno como suporte físico de registros textuais e gráficos. Partindo da ideia de que o caderno pode ser feito antes e depois do registro, questionamos se essas diferenças não seriam índices do modo de trabalho de um artista. A depender disso, o artista pode privilegiar o uso sistemático do caderno ou ainda trabalhar com folhas esparsas, em tempos e lugares distintos. Isso nos parece análogo à dialética ternura/injúria proposta por Paulo Silveira (2008), como modo de lidar com livros: mantendo sua integridade física e simbólica (ternura) ou transgredindo sua narratividade, materialidade e função (injúria).

Como "Hansel y Gretel" Urbanos: creando un trazado invisiblem y esperanzado
Authors: González Liana 
Published: April 2024

Considerando que la ciudad/lo urbano/la urbanidad son algunos de los gestores de las configuraciones sociales/estéticas de la contemporaneidad, y considerando que uno de los más genuinos productos de esta contemporaneidad es la basura, se está construyendo herramientas para dibujar, tejer, el mapa cotidiano del hombre que hace el acto de coger basura significar dignidad. Es una construcción que empieza con la mirada al hombre invisible en la organización social y que vive al lado de sólidas instituciones que poco o casi nada hacen para cambiar su condición de desplazado. Camina por las mismas calles que nosotros pero la calle para él no es camino, es tesitura. En la calle está su posibilidad del día de mañana. Así como “Hansel y Gretel” se pierden en el bosque porque los pájaros comen las migas de pan que dejan a marcar el camino, este hombre que migra para las metrópolis latinoamericanas se pierde dentro de la ciudad y no encuentra el camino de vuelta. Muchos de ellos no quieren encontrar ese camino y se transforman, se adaptan, encuentran un invisible camino dentro de las posibilidades de la basura: un camino esperanzado.
Estar Dentro da Imagem: Tactsignos
Authors: Franca-Huchet Patrícia 
Published: April 2024

Resumo: Este texto apresenta uma reflexão sobre a imagem através da percepção de suas formas de produção em um movimento artístico. Observa o processo de construção de imagem na instalação “Mitologic Motiv” (2006) — que tem a figura da árvore e da mão como motivo — e rememora formas de trabalho anteriores; o que nos faz acreditar que em cada processo artístico é necessário reiterar para que algo realmente permaneça como conhecimento.
"Intemperie". Una Poética en el Cruce Entre el Campo y la Memoria
Authors: Ribas Diana 
Published: April 2024

En la obra “Intemperie”, el colectivo “La habitación infinita” anudó hilos artísticos, sociales, espaciales e históricos en una compleja trama poética, mediante estrategias de desplazamiento, de exhibición y de gestión colectiva. Esta propuesta presentada por Toia Bonino, Cristian Delgado y Nicolás Testoni en la Bienal Regional de Arte (2014) organizada por el Museo de Arte Contemporáneo de la ciudad de Bahía Blanca (Argentina), consistió en una doble intervención. Por un lado, en una de las salas del Museo se proyectó un vídeo sobre una de las ventanas, acompañado de documentación de consulta y postales. Por otro, fue organizado un evento artístico-social en la estación ferroviaria Tres Cuervos, ubicada a 170 km de Bahía Blanca y a unos 7 km de la pequeña localidad de Darregueira. Las imágenes de ambos lugares remitían a la memoria colectiva de la región: la estructura ferro -portuaria construida por el modelo agro-exportador desde el último cuarto del siglo XIX y el cierre de las líneas ferroviarias producido en los años noventa como consecuencia de las políticas neoliberales. Al mismo tiempo, la audición de sonidos tensionaba la experiencia al indicar contrastes, sugerir migraciones y una cadena productiva a la que se le había abortado el comienzo. Inserta en la recuperación de lazos sociales y políticos planteada durante la década kirchnerista, “Intemperie” problematizó el campo artístico al expandirlo, construir un lugar específico y posibilitar el acceso de pobladores rurales a experiencias audiovisuales.

Experiência Poética, Contemporaneidades e Resgate da Poesia em Língua d'Oc
Authors: Pouliquen Jean-Luc , Paz Gaspar 
Published: April 2024

Entrevista conceidida a Gaspar Paz.“Viver antes de escrever. Mergulhar profundamente na poesia, com o desejo de deixar estilhaços sobre a página” (Pouliquen, p. 122). Eis a verve poética revelada pelo poeta francês Jean-Luc Pouliquen, que desde cedo se pôs a viajar no movimento das palavras, imagens, ações, sonoridades e sentidos. É nessa construção vivida que o escritor encontra a mistura dos materiais e culturas que tecem seus poemas. Marcado pela estética surrealista e pela geração Beat, Pouliquen se deixa invadir pelas linguagens artísticas contemporâneas e escreve “em travelling, com zoom, no contra-plano” (Idem, p.76) apreendendo também as memórias indeléveis da tradição dos poetas de língua d’Oc, da escola de Rochefort e da filosofia de Gaston Bachelard, cujas obras ele resgata em excelentes edições. Com formação em ciências políticas, atuante na crítica literária, nosso autor transita também pelo terreno musical. É com essa bagagem e astúcia crítica que ele expõe suas opiniões sobre poesia, filosofia, música, cultura, educação, variedades e política, numa entrevista envolvente.
