Onshore and offshore multiphase pipelines provide a safe and effective solution for the transport of fluids from wells to production plants in the oil and gas industry. For the control of the accumulated amount of liquid present in the pipeline (the so-called liquid holdup) and for the regular maintenance of the pipeline, pigs (Pipeline...

Industrial clusters are facing major challenges in transitioning away from their carbon-intensive activities in order to accelerate the energy transition away from fossil fuels. Therefore, the industrial clusters; the Port of Rotterdam, Chemelot, North-RhineWestphalia (NRW) and Transition System Operator (TSO) GasUnie are planning to develop a...

Humanity faces the challenge of dealing with resource exhaustion and environmental destruction. The root of these issues lies in the linear economic model established after the industrial revolution. This model relies on two fundamental principles, limitlessness and easily accessible resources and unlimited earth regenerative capacity. The...

Introduction: Radiation is an effective treatment to increase overall mean survival of patients with metastatic brain tumours, however, damage to healthy tissue is inevitable. Radiation can cause dysfunction of the cerebrovasculature which is hypothesised to induce cognitive decline in patients after radiotherapy (RT). A new method, the...

Residue amplification plays a key role in determining the energy efficiency, area and performance of high-speed pipelined ADCs. At its core, a residue amplifier simply consists of four transistors that transfer a differential input voltage to a capacitive load with the desired gain. However, in order to ensure gain accuracy over PVT, the core...

Pick and place systems that operate in a warehouse setting have been studied a lot recently due to the high economic value for e-commerce companies. In this thesis, the focus is on the perception pipeline that performs object recognition given a certain input data stream (typically RGB-D images). Impressive results regarding object recognition...

The Sines H2 Hub aims to take advantage of Portugal’s solar resources and push for a green hydrogen hub centred in Sines. To do so, a 1GW electrolyser is expected to be built by 2030. The gas produced, which will have the same production profile as the solar irradiance, can be injected in the gas grid, distributed by truck or shipped to the...

Offshore pipelines represent major items in the oil and gas industry nowadays. These submarine pipelines are usually covered with backfill for protection and a well-known method for this is sand backfilling with a trailing suction hopper dredger (TSHD). Although pipeline installation with a TSHD is a developed technique, there are still some...

With the advent of large-scale application of hydrogen, transportation becomes crucial. Reusing the existing natural gas transmission system could serve as catalyst for the future hydrogen economy. However, a risk analysis of hydrogen transmission in existing pipelines is essential for the deployment of the new energy carrier. This paper...

Urban gas pipelines usually have high structural vulnerability due to long service time. The locations across urban areas with high population density make the gas pipelines easily exposed to external activities. Recently, urban pipelines may also have been the target of terrorist attacks. Nevertheless, the intentional damage, i.e. terrorist...

Submarine slope instabilities are considered one of the major threats for offshore buried pipelines. This paper presents a novel method to evaluate the ultimate pressure acting on a buried pipeline during the liquefaction of an inclined seabed. Small-scale model tests with pipes buried at three different embedment ratios have been conducted...

This work discusses the design and demonstration of an in-situ test setup for testing pipeline steels in a high pressure gaseous hydrogen (H2) environment. A miniature hollow pipe-like tensile specimen was designed that acts as the gas containment volume during the test. Specific areas of the specimen can be forced to fracture by selective...

Circular economy (CE) and sustainability are high on the political agenda of governments nationally and internationally. Governments are developing instruments to stimulate the CE, but without monitoring in place, these measures can be subject to abuse, failing to achieve the desired effects. CE monitoring, however, is still a nascent topic in...

With fossil fuels being phased out and growing global interest in a hydrogen economy, there is demand for re-purposing existing pipelines for transportation of hydrogen gas. However, hydrogen embrittlement (HE) can limit pipeline steel’s performance. In this study, the effect of hydrogen on the mechanical properties of an X60 base metal ...

Core-annular flow is an efficient way of transporting viscous oil through a pipeline. A sharp increase in the pressure drop will occur when the oil waves at the water-oil interface touch the pipe wall. Depending on the oil and pipe material physical properties, the oil may adhere to the wall leading to fouling. Therefore, a necessary...

Circular economy and sustainability are high on the political agendas of governments. Governments, but also other actors like banks, insurance companies, and auditing firms play a key role in setting (regulatory) requirements, instruments and incentives, as well as monitoring mechanisms to stimulate and monitor CE activities. Governance of CE...

Objective. Large structural brain changes, such as chronic stroke lesions, alter the current pathways throughout the patients' head and therefore have to be taken into account when performing transcranial direct current stimulation simulations. Approach. We implement, test and distribute the first MATLAB pipeline that automatically generates...

Designing low-cost network layouts is an essential step in planning linked infrastructure. For the case of capacitated trees, such as oil or gas pipeline networks, the cost is usually a function of both pipeline diameter (i.e. ability to carry flow or transferred capacity) and pipeline length. Even for the case of incompressible, steady flow,...

Gas drainage system is a critical technique to prevent gas outbursts in the underground coal mine. The leakage of gas drainage pipelines can pose serious threats to the safety production of underground mining. In this paper, a multi-factors gas drainage pipeline leakage and diffusion (GDPLD) model is proposed based on the OpenFOAM platform,...

By their very nature, voltage/current excited Spin Waves (SWs) propagate through waveguides without consuming noticeable power. If SW excitation is performed by the continuous application of voltages/currents to the input, which is usually the case, the overall energy consumption is determined by the transducer power and the circuit critical...
