Several papers are currently being written, requiring the review of numerous documents and consultations with scientists involved in the discussed topics, who have their own schedules, thus extending the writing process beyond the initially anticipated timeframe. Additionally, these papers are partially based on some scientific articles that have not yet been published. Consequently, their publication is not expected before the beginning of the new year. In the meantime, many new documents have been added to the website's database, necessitating updates to the previously written manuals and studies. As a result, the following documents have been modified before a more thorough revision of these manuals that is planned for next year:
The chapter on decompression accidents in Book #1, "Description and Prevention of Diving Accidents," from the surface-supplied diving handbooks DCIEM and MT 92, has been revised to incorporate conclusions from scientific studies available in the database on yoyo diving, repetitive diving, inverse profiles, as well as bubble detection and interpretation. These modifications in Book #1 have, naturally, affected articles in Book #3, "Air
documents as references. We can attribute this to the fact that they are based on a variety of information sources, which have been carefully selected and compiled to provide the most relevant and balanced guidelines possible. The "Basic Rigging and Lifting Procedures Handbook," designed to organize lifts that do not require specific engineering, can be considered an example of this approach.
and Nitrox Procedures Using In-Water and Surface Decompression," which have been adjusted accordingly. We are also considering whether splitting these manuals into a series of shorter documents is desirable. Advice on this point is welcome. Please note that reputable scientists are increasingly using our
This document provides relevant guidelines for underwater and at- sea lifting operations. It emphasizes the importance of understanding and utilizing official standards and appropriately integrating them to ensure the safety of these complex operations.
The study titled "Problems in Selecting a Decompression Table for Saturation Diving for Commercial Purposes in Poland - Part I," authored by Doctors Stanisław Skrzynski and Piotr Siermontowski discusses guidelines and methods for analyzing and comparing saturation diving procedures. It focuses on their application within the Polish Baltic Shelf to identify suitable technologies for the region by reviewing existing procedures, discussing

This article discusses the importance and challenges of implementing Closed Circuit Television (CCTV) systems on vessels or sites where diving and Remotely Operated Vehicle (ROV) operations are conducted. It highlights the role of CCTV in enhancing safety and operational efficiency, the difficulties faced when integrating these systems on vessels not initially designed for such operations, and the potential solutions, including the use of Wi-Fi systems to overcome technical and spatial constraints. It aims to inform and possibly persuade those in charge of such operations about the necessity and benefits of robust CCTV systems in these environments and provides a list of manufacturers of quality equipment designed to work in the most severe conditions, including explosive atmospheres.

Author: Doctor Jean Yves Massimelli University Hospital Center - Nice, France This article advocates a proactive safety culture prioritizing worker well-being and adherence to industry standards and regulations. It identifies and addresses significant safety concerns and risks associated with commercial diving operations in the oil and gas industry, emphasizing the need for rigorous safety standards, proper risk management, and adherence to best practices to protect divers and other personnel involved in these operations. It also calls for accountability from oil and gas companies and diving contractors, urging them to prioritize safety over cost-cutting measures and outdated practices. About the author: Doctor Jean Yves Massimelli studied in Marseille and Nice. After acquiring experience in emergency medicine, including during his National Service, he entered the commercial diving world through Comex, where he first medically supervised innovative inland diving projects for the nuclear industry. Mentored by the Comex' pioneers and experts, he was appointed to coordinate the medical team in charge of the 701msw hydrogen-helium-oxygen saturation dive, in 1992, in the Comex Marseille's hyperbaric centre. He has been practising occupational medicine and diving medicine, leading numerous teams and projects, mainly in France and in Asia. His dedication to Divers's health and safety and his enthusiasm for innovation have been driving his career. Since January 2022, Dr Jean-Yves Massimelli has been in charge of the coordination of the occupational medicine department at the University Hospital in Nice, France, Click on the button below to open this post.
