The Diving Management Study #13, which addresses the regulations and instruments established to guide the work of scientists in designing dive tables, is still in progress. The subject necessitates the review of numerous documents and consultations with scientists engaged in developing decompression tables, extending the writing process beyond the initially anticipated timeframe. Consequently, its publication is not expected before the end of this year.

The document IMCA D 050, “Minimum Quantities of Gas Required

The Diving Management Study #4by CCO Ltd., titled "Strengthen the U.S. Navy Saturation Procedures," has been enhanced. Initially published in 2014, the study aims to demonstrate the feasibility of strengthening the U.S. Navy's saturation procedures by adopting elements from recognized competent bodies. This approach ensures safer practices and meets the approval standards of clients who require that their

Offshore", has recently been reviewed by its issuer. As the previous edition was the subject of the Diving Management Study CCO Ltd. #7, "History and Evaluation of IMCA D 050 Rev. 1", this latest update by IMCA needed to be evaluated again. This was an opportunity to improve the document. Note that IMCA did not make major changes to the previous edition, so the remarks made in the previous evaluation remain applicable.

contractors' decompression procedures be issued by or approved by recognized competent bodies. Additionally, the study now includes a summary of "A Review of Accelerated Decompression from Heliox Saturation in Commercial Diving Emergencies" by Jean-Pierre Imbert, Jean-Yves Massimelli, Ajit Kulkarni, Lyubisa Matity, and Philip Bryson.

To conclude, this guidance can be used despite being far from perfect.

The document “Hydration status during commercial saturation diving measured by bioimpedance and urine specific gravity” by Doctors Stian Lande Wekre, Halvor Dagssøn Landsverk, Jacky Lautridou, Astrid Hjelde, Jean Pierre Imbert, Costantino Balestra, and Ingrid Efteda, evalutes the hydration status of divers during a saturation diving campaign at 74 m. The reasons for this evaluation are that dehydration is associated with reductions n

The study "In-field use of I-VED electrical impedance sensor for assessing post-dive decompression stress in humans", by Doctors Sotiris P. Evgenidis, Konstantinos Zacharias, Virginie Papadopoulou, Sigrid Theunissen, Costantino Balestra, and Thodoris D. Karapantsios, evaluates whether post-dive bubbles can be assessed using I- VED, an application of bioimpedance focusing on the assessment of intravascular volumes.

The previous website edition recommended focusing on ultrasonic procedures. To continue with detection systems, we recommend two documents discussing the use of bioimpedance. This noninvasive and low-cost technique involves measuring the electrical properties of biological tissues to assess their condition and can be used for detecting stresses during and after diving.

The construction of underwater foundations is a source of noise that impacts the immediate environment and is gradually being taken into consideration. The document "Revolution Wind Underwater Acoustic

The "Revised Danish Guidelines for Underwater Noise from Installation of Impact or Vibratory Driven Piles" by René Schmidt Lützen, Søren Keller, and Jakob Tougaard, describes the environmental protection processes first implemented in 2016 by the Danish government to protect marine mammals. These processes were reviewed in 2022 and extended to other forms of underwater life

Analysis: Impact Pile Driving during Turbine Foundation Installation," by Samuel L. Denes, Michelle J. Weirathmueller, and Elizabeth T. Küsel, presents the results of acoustic modeling for pile driving activities. In addition to the emissions from piling activities, the noise from the dynamic positioning thrusters of the vessels used during piling, cable installation, and transit is also considered.

This article presents a cardiopulmonary resuscitation (CPR) device specifically designed to operate in closed bells and chambers that scientists have recently tested. The offshore industry, among others, has gradually adopted devices such as portable defibrillators, considering them an efficient alternative to manual CPR. As a result, they are now commonly provided at strategic points in various facilities and support vessels. Based on this policy, equipping bells with tools for cardio-resuscitation should efficiently assist divers in the event they need to perform CPR within the bell.

About the Compact Chest Compression Device by NUI

Will bio-inspired underwater vehicles with artificial intelligence replace divers?

Articles on bio-inspired underwater vehicles using "artificial intelligence" (AI) are constantly being added to our website. The oldest document explicitly mentioning AI currently in our database is a research paper entitled "A Survey of AI Techniques for Control of Underwater Vehicles" by Pepijn van de Ven, Colin Flanagan, and Daniel Toal, published in April 2003. However, despite the recent surge in "artificial intelligence" discussions, it is important to note that the concept is not new and dates back to the early days of the computer industry before the Second World War. Advances in electronics and computing have paved the way for the development of autonomous vehicles capable of performing various tasks automatically. In addition, the use of new materials has made it possible to replicate the characteristics of underwater creatures such as fish or octopuses, thereby increasing the machines' adaptability. As a result, these vehicles are often used to replace divers, leading to a logical discussion about whether they will eventually replace divers altogether.
