Analysis of Fatigue Monitoring of Deepwater Drilling Riser

Shiyou jixie, 2017
The riser is the key equipment for deepwater drilling, which is prone to fatigue damage in harsh deepwater environment, so it is very important to monitor the fatigue of deepwater riser.

Eocene Tectonic Change in the South Pacific Caused Exhumation of the Transantarctic Mountains in Northern Victoria Land, Antarctica

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Apatite fission‐track and (U‐Th)/He data indicate rapid exhumation of northern Victoria Land at 40–30 Ma, correlating with opening of Adare Trough at 43–28 Ma. Exhumation was greatest close to the Ross Sea, consistent with other regions of the Transantarctic Mountains.

Salt-Resistant Lubricant for Deep Water Drilling Fluids

Zuanjingye yu wanjingye
In deepwater drilling, drilling fluids are affected by seawater, highly mineralized brine, and polyvalent metal ions. Conventional lubricants such as mineral oils, vegetable oils, and fatty acids often exhibit poor dispersion and incompatibility in high ...

State of the Practice − Sub‐Aqueous In‐Situ Solidification for Contaminated Sediment Remediation

Remediation Journal, Volume 36, Issue 4, Autumn 2026.
ABSTRACT In‐situ solidification (ISS) has emerged as a cost‐effective and versatile technology for sediment remediation, particularly for addressing contamination at greater sediment depths. This paper evaluates ISS in the context of conventional sediment remediation approaches, highlighting its advantages, design and implementation considerations, and

Marine Snow Dynamics in the NE Gulf of Mexico: Particle Abundance, Characteristics, and Impacts on Deepwater Horizon Oil Sedimentation

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract The Deepwater Horizon (DWH) oil spill in the NE Gulf of Mexico in 2010 was the largest accidental spill globally. During and after the spill, oil was incorporated into marine snow (marine‐oil‐snow or MOS) and sedimented to the seafloor, accounting for ∼21% of the oil released.
