BLOCOS URBANISM: Capitalism and Modularity in the Making of Contemporary Luanda

open access: yesInternational Journal of Urban and Regional Research, Volume 47, Issue 5, Page 809-832, September 2023., 2023
Abstract In this article we portray and unpack the fabric of urban expansion in contemporary Luanda. In doing so, we examine interdependencies and complementarities between the organization of oil extraction off the coast of Angola, the emergence of particular modalities of modernist city planning for the expansion of its capital city, and the ...

[Retracted] Assessing the Feasibility of Cogeneration Retrofit for Heating and Electricity Demands in Marine Diesel Engines

open access: yesInternational Transactions on Electrical Energy Systems, Volume 2023, Issue 1, 2023., 2023
In the marine engineering industry, turbocharged diesel engines are often used to generate electricity, and hot oil can be extracted after generating electricity. However, marine diesel engine heat recovery can be distinguished from gas heat recovery for turbocharged and nonturbocharged diesel engine systems.

Effect of cyclic softening and mean stress relaxation on fatigue crack initiation in a hemispherical notch

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 45, Issue 12, Page 3592-3608, December 2022., 2022
Abstract Corroded surfaces of offshore mooring chains typically show a very irregular shape with different pit geometries. Fatigue tests were performed in three‐point bending on specimens with hemispherical notches, representing an idealized geometry of a corrosion pit.

Evaluating technical and financial factors for commercialising floating offshore wind: A stakeholder analysis

open access: yesWind Energy, Volume 25, Issue 11, Page 1959-1972, November 2022., 2022
Abstract Recently, floating wind has enjoyed much public and governmental attention and is commonly identified as a crucial next step on the route to net zero targets for many countries. However, there is currently a large gap between the scale and readiness‐level of devices in the water and the end‐of‐ the‐decade aspirational targets of many ...

Influence of offshore oil and gas structures on seascape ecological connectivity

open access: yesGlobal Change Biology, Volume 28, Issue 11, Page 3515-3536, June 2022., 2022
Offshore platforms and related fixed structures supporting the oil and gas (O&G) industry are prevalent in all oceans. We review current knowledge on the role of O&G infrastructure in maintaining, altering or enhancing ecological seascape connectivity. There is a paucity of studies assessing connectivity and O&G structures.

Mathematical Physics Modelling and Prediction of Oil Spill Trajectory for a Catenary Anchor Leg Mooring (CALM) System

open access: yesAdvances in Mathematical Physics, Volume 2022, Issue 1, 2022., 2022
The catenary anchor leg mooring (CALM) system usually moored a heavy oil tanker; due to its complex working mechanism and special working environment, oil spill accidents are easy to happen. Once the oil spill accident happens, it not only causes huge economic loss, but also kills the marine ecological environment.
