THINGSplus: New norms and metadata for the THINGS database of 1854 object concepts and 26,107 natural object images
Authors: Stoinski Laura M. , Perkuhn Jonas , Hebart Martin N. 
Published: April 2023

AbstractTo study visual and semantic object representations, the need for well-curated object concepts and images has grown significantly over the past years. To address this, we have previously developed THINGS, a large-scale database of 1854 systematically sampled object concepts with 26,107 high-quality naturalistic images of these concepts. With THINGSplus, we significantly extend THINGS by adding concept- and image-specific norms and metadata for all 1854 concepts and one copyright-free image example per concept. Concept-specific norms were collected for the properties of real-world size, manmadeness, preciousness, liveliness, heaviness, naturalness, ability to move or be moved, graspability, holdability, pleasantness, and arousal. Further, we provide 53 superordinate categories as well as typicality ratings for all their members. Image-specific metadata includes a nameability measure, based on human-generated labels of the objects depicted in the 26,107 images. Finally, we identified one new public domain image per concept. Property (M = 0.97, SD = 0.03) and typicality ratings (M = 0.97, SD = 0.01) demonstrate excellent consistency, with the subsequently collected arousal ratings as the only exception (r = 0.69). Our property (M = 0.85, SD = 0.11) and typicality (r = 0.72, 0.74, 0.88) data correlated strongly with external norms, again with the lowest validity for arousal (M = 0.41, SD = 0.08). To summarize, THINGSplus provides a large-scale, externally validated extension to existing object norms and an important extension to THINGS, allowing detailed selection of stimuli and control variables for a wide range of research interested in visual object processing, language, and semantic memory.

Abstract:
Objective: COVID-19 has caused a rapid transformation in the healthcare system, including in particular, the care of vulnerable cancer patients. The aim of this study was to present our clinical experience in gynecological cancer surgeries in a COVID-19-free cancer hospital during the pandemic.

Methods: A retrospective analysis was made of the data of patients with ovarian, endometrium, cervix and vulva cancers who were treated with surgery between March 2020 and March 2021, with particular focus on the complication rates on day 30, and at the end of one year.

Results: The study included a total of 74 patients with mean age of 59 years. The most common diagnosis was ovarian cancer (48.6%) followed by endometrial (43.2%), cervical (6.8%) and vulvar cancer (1.4%). Most of the patients were in advanced stage (FIGO 3 and 4) of ovarian (86%), endometrial (59.4%) and cervical local advanced (60%) cancer. The complication rate was 17.6 %. Surgery was delayed in one patient with a preoperative positive polymerase chain reaction (PCR) test for COVID-19 infection, and none of the patients had a positive test result in the early postoperative period.

Conclusion: COVID-19-free institutions for cancer surgery, is an effective treatment strategy in the context of the pandemic. The results of this study indicate that continuity of cancer treatment can be achieved safely, with strict adherence to COVID-19 precautions for both patients and healthcare workers.

Steel Stress Joint Design and Fabrication Challenges with 3.5-Inch Mid Joint Fatigue Sensitive Weld for the Vito Oil Export Steel Catenary Riser

Published: April 2023

Abstract
This paper describes the steps and the challenges encountered during the design and fabrication of the 100-foot long steel stress joint for the 14-inch Vito Oil Export Steel Catenary Riser (SCR) and how the project team was able to overcome them, leading to a successful completion and installation of the stress joint and the SCR by the S-lay method. The stress joint was made up of two sections with 3.5-inch upset (thickened) ends welded together, due to globally available forging size limitations. The stress joint had to be designed to accommodate the Vito semi-submersible platform motions and support the load of the riser. This steel stress joint may not be the longest, however, it could well be the largest and heaviest, having the thickest weld ever attempted on a fatigue critical area of an SCR. This stress joint, in particular the weld, had to satisfy the design fatigue requirements and meet a very stringent Engineering Critical Assessment (ECA) flaw acceptance criteria.
During the manufacturing of the steel sections, indications were found in the steel forgings and the design had to be adjusted to eliminate the sections with the indications and to save the forgings from being scrapped and preserve project schedule. The manufacturing and fabrication of the steel joint was challenging from a materials point of view as well as due to the size of the segments which necessitated the joining of two separate forgings, limited by both length and weight. In addition, the qualification and welding of the 3.5-inch upset (thickened) ends of the two stress joint pieces presented significant risk for the project as it has never been done before and this weld represented one of the most fatigue critical locations in the SCR. This weld also had to meet very stringent flaw acceptance criteria to meet the weld ECA requirements and had to be produced without the ability of being repaired. The unique challenges in developing the welding and the Non-Destructive Examination (NDE) procedure and the welding qualification process for the 3.5-inch thick weld are also discussed in this paper.
Introducing a Novel Shaped Steel Catenary Riser for Deepwater Applications
Authors: Sebastian Abhilash A , Lal Mayank , Rana Yash K 
Published: April 2023

Abstract
Use of steel catenary and lazy wave risers has increased as oil and gas developments are happening in deeper waters or in parts of the world with no pipeline infrastructure utilizing Floating Production Storage and Offloading (FPSO) vessels as a host platform. A suitable Catenary form is selected based on the hang-off angle of the riser. Lazy-Wave form of the catenary riser is achieved by targeted placement of a custom configured buoyancy section. This includes the length to start of the buoyancy section, length of the buoyancy section, hang-off angle, and the buoyancy factor. The strength and fatigue performance of steel catenary and lazy wave risers are governed by its configuration parameters. Achieving these key performance drivers for an SCR or SLWR takes several rigorous analyses iterations throughout the design process. However, on many occasions a modified and optimized Shaped Steel Catenary Riser (SSCR) is necessary to satisfy the project technical, operational, and economic requirements. In certain instances, there is simply no solution achievable using a monolithic steel catenary or lazy wave riser. These include instances where an SCR may be technically feasible, however the top tension is too high or an SLWR simply doesn't have adequate operational fatigue. A shaped Steel-Titanium Riser (STIM Riser) allows to decouple the vessel motions sufficiently and reduces the hang-off tensions. The concept also provides good long-term and short-term fatigue due to environmental factors including wave and currents and operational factors such as slugging.
In this paper a novel hybrid shaped riser is introduced. This riser system takes advantage of the modified catenary riser to achieve an optimized shaped SCR and combines it with the superior fatigue performance of Titanium. Titanium is abundant in the nature but currently difficult and expensive to extract at large scale. The industrial solution to produce Titanium at a greater scale is expected to improve in the near future. In that scenario, a riser system with Titanium applied to several critical areas will provide an attractive solution. This customized solution provides an attractive cost optimized configuration that meets all requirements.
Standardization of Subsea Distribution Units

Abstract
There has never been a more challenging time for the energy industry. In the subsea sector, the search for optimised costs, minimized carbon emissions, and maximized performance is set to intensify as oil prices continue their unpredictable trajectory.
At the same time, the risks to equipment, to people, to the local terrain and seascape will remain. What the industry needs in the face of all this is cost certainty and reduced CO2 output, derived not just from technical certainty but also execution certainty.
As part of the goal to achieve carbon net zero status, every single aspect of subsea operations is an opportunity to drive improvement. Through the work undertaken as described in this paper to drive standardization across the industry around the world, it can be shown that even equipment like Subsea Distribution Unit (SDU) – that come with some entrenched design and operational philosophies behind them – can deliver substantial improvements to the areas that matter most such as reduction of carbon footprint.
Data from past projects and from the market have been collected to map the main configurations delivered across the years for different Clients in order to assure that the SDU structured is a flexible product that can be configured easly to cover all possible requests: the brick has been introduced as main component of the SDU. The design of standard bricks improves production availability, reduce production time as result of reducing on-site welds. Not a secondary aspect is that the standardization of the design translates in a standardization of the manufacturing and execution phases, which means a reduction of lead time (up to 6 months) with an improved availability of the product. In addition to the above, a reduction in the weight of ~20% it has been obtained: this with the possibility to use smaller vessel contribute massively to the reducyion of the CO2 emission.
Numerical Analysis of a Wave Energy Converter

Published: April 2023

Abstract
Wave Energy Converters (WEC) are devices that convert the kinetic energy of the waves into useful electrical energy. There are multiple types of WEC devices that have been developed over the years. These devices act as a source of clean energy and can be used to generate electricity. This paper provides a numerical assessment of a WEC device comprising of a moored buoy with a Power Take-Off (PTO) system driven by line tension.
This WEC system was developed by Laminar Scientific. AMOG was contracted by Testing and Expertise for Marine Energy (TEAMER) to provide a numerical assessment of this WEC device under metocean conditions present at the PacWave site.
The WEC system was modeled using the hydrodynamic package OrcaFlex, over a range of regular and irregular sea-states of varying wave height and period. Four optimization steps were made to the model, altering parameters of the original model such as size and geometry.
The simulations indicated that the WEC device power output is highest for large surge and heave motions of the buoy. The simulations also predicted that increasing the surge and heave motions lead to a critical point beyond which the PTO system was no longer able to respond rapidly enough to maintain minimum tension in the mooring lines. Beyond this point snatch loads were predicted to occur potentially exceeding the Minimum Breaking Load (MBL) of the lines and accompanied by unstable rotational motions of the buoy. Increasing the size of the buoy was predicted to prevent these snatch loads and associated unstable rotational motions of the buoy from occurring in the range of sea states investigated. The parameters which were predicted to have the most impact on the system performance were the buoy size (mass, moments of inertia, and volume) and the rotational inertia of the PTO system. Increasing the buoy size and decreasing the PTO rotational inertia was predicted to improve the power generation capabilities of the device.
Hybrid Power Sources in ROVs - Turbocharging Electric ROVs with Technology from the Electric Vehicle Industry
Authors: Schubert Peter Bertan 
Published: April 2023

Abstract
As Remotely Operated Vehicle (ROV) technology matures, it will benefit by borrowing new components and techniques from related industries to improve performance and reduce costs. A particularly important area to draw from is the electric vehicle industry. ROVs are typically powered and controlled from a cable called a "tether" and the maximum power which can be provided to the vehicle is a function of the tether size and the required length. What if the ROV had a "turbo" mode, much like a hybrid gas/electric vehicle using a small amount of energy storage and an electric motor to provide short bursts of additional power? A prototype "hybrid" energy storage system is used to demonstrate how peak power available to the ROV can be increased or the size of the tether can be reduced. The prototype is based on a component commonly used in electric vehicles called a supercapacitor. Data from test dives shows the vehicle typically reaches peak power for only 5 seconds. Anytime the power demand of the vehicle is below the maximum available from a traditional power supply, energy could be stored in the supercapacitors for later use, allowing greater power output when required. The data is also used to estimate tether savings/performance gains using this technique. Thanks to great strides in electric vehicle technology, ROV capability and efficiency will improve significantly. In much the same way adding even a small electric motor and batteries or supercapacitors to a typical gasoline powered car results in a "hybrid" vehicle with either the same performance at greater fuel economy or increased performance at the same milage, ROV operators will benefit from a combination of reduced costs/carbon emissions or increased power.
On the Use of DAS, DTS and DTGS for the Detection and the Monitoring of Leaks in Wells
Authors: Cherubini Aurelien , Almoric Etienne 
Published: April 2023

Abstract
Distributed Acoustic Sensing (DAS) and Distributed Temperature Sensing (DTS) measurements are technologies which are adding some benefits in the aim to replace or complete traditional logging measurements like noise logging tools (NLT) or production logging tools (PLT). The aim of well integrity interventions using distributed fiber optic sensing (DFOS) is to significantly reduce the duration and the cost of these operations, and to provide additional information in comparison to traditional logging tool. The combination of DAS and DTS can offer both qualitative and quantitative information regarding fluid dynamics in the context of well integrity investigation, as the flow characteristics (intensity of turbulences).
In addition to acoustic (high frequency DAS) and temperature (DTS) monitoring for leak detection, we propose to use DTGS (Distributed Temperature Gradient Sensing) with low frequency DAS (&lt; 1 Hz) to monitor leaks on the completion tubing of a well. The main advantage of using DTGS with DAS is its sensitivity to small leaks, including the direction of propagation of the leak.
Electrical Protection From Design to Commissioning for Subsea Electrically Heat Traced Flowline Pipe in Pipe System, The Challenge of Inaccessible Subsea Electrical Assets.
Authors: Minier Yves , Silcock Donald Maclaren 
Published: April 2023

Abstract
This paper will describe the analysis, optimisation and subsequent implementation of an electrical protection system utilised on a subsea Electrically Heat-Traced Flowline system (EHTF) using conventional topsides power protection equipment deployed in a novel topology.
It will also discuss the project-imposed challenge of protecting an electrical subsea system of significant length from only a single feeder protection whilst keeping it simple, sensitive, rapid, and covering 100% of the long heating cable length.
The paper will describe the detailed electrical analysis methods deployed, the additional electrical verification carried out and the decision-making processes and drivers choice used during an electrical system design optimisation challenge that was conducted in a short timeframe and planned around operational assets.
The close collaboration between contractor, client, vendors and third-party expertise was fundamental to solve successfully the challenges and mitigate the overall risks.
Key engineering processes described: Subsea Umbilical Riser and Flowline (SURF)/Topside interface management / interface meetings, design review process, use of interim design reviews, the decision scoring matrix, the go/no go risk assessments, pre-commissioning, commissioning, performance test.
The benefits and drawbacks of the different electrical topologies investigated will be reported, specifically the retention of an isolated neutral system.
The paper will provide the final chosen protection topology and the results of the individual component testing.
A key observation to report being that when technology is new, the need to validate the implementation of it must be included in the initial design. There must be added monitoring even if it’s not thought to be essential at start of a project, even if it’s considered as "sugar coating" a design or adding complexity, there can be huge benefits on new technology deployment.
The paper will report on the observed benefits of site integration testing versus individual routine / factory acceptance testing when deploying TRL7 items in novel topologies.
The final commissioning results will be reported and an engineer’s view of a journey from concept to final commissioning will be presented.
Existing literature is limited on electrical topology on subsea infrastructures and thus this paper enhances the industry knowledge base. The paper describes a novel topside protection system for subsea ground isolated loads.
As the subsea industry turns towards electrification, it is essential that lessons are learned. This ensures novel solutions can be deployed provided a correct design verification process.
The paper could trigger discussions around a new best practice recommendation about the interface topsides/subsea electrical infrastructures.
API Technical Report – Guidance for the Integrity Management of Weathervaning Systems
Authors: Spong Robert , Deschamps Rodney , Bhattacharjee Subir , Byatt David , Gallagher Daniel 
Published: April 2023

Abstract
Presently, limited guidance is available to the industry on best practices for managing the integrity of weathervaning systems for floating assets. Weathervaning systems include internal and external turrets, tower yoke turrets and loading/offloading buoys. Components that make up these systems (i.e., bearings, lubrication systems, swivels, leak recovery systems, connection and release systems) are critical to the weathervaning capability of offshore Floating Production Storage and Offloading (FPSO) and Floating Storage and Offloading (FSO) Systems (hereon collectively referred to as Floating Production Systems or FPS) as well as loading/offloading buoy systems. They are also critical to maintaining production and disconnection/reconnection to avoid extreme events. To maintain these complex systems, a multi-discipline offshore integrity team (e.g., process, mechanical, electrical and structural) is required. As a result of these complexities, it is often challenging for offshore operators to understand all the subsystems and manage the long-term integrity.
Recognizing this limitation, the American Petroleum Institute (API) commissioned a project to develop guidance on managing the integrity of weathervaning systems. The resulting new API technical report addresses this limitation by providing information from OEMs, and operators on the various component functions, complexities, deterioration mechanisms along with guidance on typical activities required to maintain integrity. This paper describes the development, industry engagement and content of the new API guidance document for weathervaning systems integrity management (IM).
