Iran's Gas Sector in Conflict: Infrastructure Vulnerability & Market Implications

Middle East Policy, Volume 33, Issue 3, Autumn (Fall) 2026.
Abstract This article examines the structural vulnerability of Iran's natural gas sector under conditions of conflict, focusing on the March 2026 strikes on the South Pars/Asaluyeh complex. Despite holding the world's second‐largest reserves and ranking among the top producers, Iran's gas system is characterized by high infrastructure concentration ...

Probabilistic Prediction of Spudcan Bearing Capacity in Stiff-over-Soft Clay Based on Bayes’ Theorem

Journal of Marine Science and Engineering
During offshore operations of jack-up platforms, the spudcan may experience sudden punch-through failure when penetrating from an overlying stiff clay layer into the underlying soft clay, posing significant risks to platform safety.

Experimental Study on the Effect of the Rack Structure on the Hydrodynamic Characteristics of Truss-type Leg

Shiyou jixie, 2019
The rack and pinion system is the most commonly used lifting system for jack-up offshore platforms. There are relatively few studies on the influence of rack structure on the hydrodynamic characteristics of truss-type legs.

Synthetic Seismic Data Generation for Deep Learning Segmentation of Clinoforms: Integrating Process‐Based Forward Stratigraphic Modelling and Ray‐Based Seismic Modelling

Basin Research, Volume 38, Issue 4, July–August 2026.
This study aims to develop a deep learning model for automated clinoform segmentation. The trained model achieved high segmentation performance on a synthetic testing dataset and successfully generalised to real seismic profiles. The proposed approach demonstrates the effectiveness of using forward stratigraphic modelling and point spread function for ...

Forecasting long term jack up vessel demand for offshore wind

, 2014
Offshore wind deployment has greatly increased in the last decade. The number and size of installations have historically determined the requirement for jack up vessels, as installation was the only driver for heavy lift vessel requirement.

Experimental study on piling and penetration behavior of jack-up offshore platforms on layered seabed foundations

Brodogradnja
This study aims to design a novel experimental system for replicating the bearing capacity behavior of layered seabed foundations during the process of leg piling and penetration. A test apparatus for a jack-up offshore platform was developed, with a telescopic pile foundation hydraulic cylinder mounted at the base of platform leg to achieve ...

Fifty Years of Shore Platform Erosion Monitoring at Kaikōura Peninsula, South Island, Aotearoa‐New Zealand

Earth Surface Processes and Landforms, Volume 51, Issue 7, July 2026.
Fifty years of micro‐erosion metre monitoring at Kaikōura show that the 2016 earthquake more than doubled shore platform erosion rates, transforming intertidal shore platforms into rapidly degrading supratidal marine terraces and reorganising the process and lithological controls that govern rock coast evolution.

Effect of Foundation Modeling on Extreme Response of Offshore Jack-up Unit

, 2010
The demand for operation of mobile jack-up drilling rigs in offshore industry is increasing. Extreme response of jack-up platforms in sea environment requires improving the understanding of their nonlinear behavior.

Full Dollarisation and Economic Performance Revisited

International Journal of Finance &Economics, Volume 31, Issue 3, Page 3869-3886, July 2026.
ABSTRACT This paper examines the economic performance of fully dollarised economies compared to those with alternative monetary regimes. Using an extensive dataset covering 192 countries from 1980 to 2021, we employ a variety of econometric techniques, including joint maximum likelihood and propensity score matching, to address endogeneity and ...

Offshore foundation systems for resource recovery: Assessing the three-dimensional response of jack-up platforms

KSCE Journal of Civil Engineering, 2011
Self-installing mobile jack-ups platforms retain a dominate role in the exploration of offshore oil and gas in water depths up to around 120 m. However, significant challenges in assessing their stability and dynamic performance under large storm loading remain.
