Our database has been enriched with the inclusion of 48 scientific studies, with publication dates ranging from 1976 to the present year. To access the list, please click on this text or on the button below.
The document, "Calculating Cumulative Pulmonary Oxygen Toxicity. Use of the Unit Pulmonary Toxicity Dose (UPTD)", by H. Bardin & C. J. Lambertsen, was the 1st article to discuss this concept we had long sought. While this system is gradually being replaced by the new Surface Oxygen Time (ESOT), it is still used in some publications and was an essential part of the studies on oxygen toxicity conducted to date.
"Physiological monitoring to prevent diving disorders" is a study by Paul Beatty, William Evans, Sara Gravelyn, and Marshall Tumperi, emphasizing the importance of studying human physiology for ensuring diver safety during underwater operations. It details various hazardous physiological phenomena that divers can experience before, during, and after dives, and discusses specific physiological biomarkers that can be used to evaluate a diver's physical condition.
We are actively expanding our database with new scientific documents. While most of these papers address diving-related phenomena, many also examine health issues associated with ROV operations and various deck activities. These documents form the essential evidence base for developing guidelines and standards, and authors of such procedures should consistently reference this foundational research.
This section contains papers dealing with technologies applicable to remotely operated and autonomous underwater vehicles. They can be considered scientific studies dedicated to the above- mentioned equipment. 29 documents have been added to our database, which contains documents from the fifties to the present days.

This article presents the development of an underwater salvage robot designed to locate and retrieve foreign objects in nuclear reactor pools. The robot features an ROV platform combined with a three- degree-of-freedom Delta robotic arm and utilizes advanced positioning and object detection technologies. Experimental tests demonstrated its high effectiveness in identifying and retrieving various foreign objects.
As indicated in previous editions, we continue expanding our database with diverse documents, many of which discuss bio- inspired underwater vehicles and advances in artificial intelligence. Among the new, high-quality papers featured in this edition, we are pleased to highlight the study, "An Underwater Salvage Robot for Retrieving Foreign Objects in Nuclear Reactor Pools," by Ming Zhong, Zihan Gao, Zhengxiong Mao, Ruifei Lyu, and Yaxin Liu.
In addition to the documents mentioned above, environmental concerns continue to grow. Therefore, 26 new papers on these topics have been added to the database, whose list can be viewed by clicking the button below.
As in previous editions, we continue to highlight the increasing reliance on Remotely Operated Vehicles (ROVs) and Autonomous Underwater Vehicles (AUVs) for non-destructive testing (NDT) inspections, mapping, and numerous construction tasks. In addition, we focus on underwater construction engineering, with emphasis on the strength and life prediction of offshore and inland structures, including, but not limited to, their foundations and protections.
“Deep Learning Approaches for Fault Detection in Subsea Oil and Gas Pipelines: A Focus on Leak Detection Using Visual Data” is a study by Viviane F. da Silva, Theodoro A. Netto, and Bessie A. Ribeiro that focused on enhancing leak detection methods in subsea oil and gas pipelines by exploiting data from experiments that simulated underwater leak conditions.
The study “Hydrodynamic Characteristic Around the Riprap Protection of Monopile Wind Power Foundation with Scour Pit During Scour”, by Tongshun Yu, Li Wang, Congbao Mei, and Xiaofeng Dong, investigates how riprap protection affects hydrodynamics around offshore wind power foundations during scour events, highlighting phenomena that may impact the foundation's stability.
Our database contains diverse environmental documents, including descriptions of fauna and flora and marine pollution studies from multiple sources. While the oil and gas industry remains a focus despite its environmental improvements, attention is also turning to other sectors, particularly inland and underwater mining.
“The impact of H2S on Hg accumulation on non-corroded pipelines and the implications for assessing risks of offshore decommissioning” is a study by Liam Paton, Sandra Kiesel, & Jorg Feldmann, highlights the need to address contaminant concentrations, such as mercury (Hg) and hydrogen sulfide (H2S), during decommissioning operations.
The study "Multi-AUV sediment plume estimation using Bayesian optimization" by von See, Greinert, and Meurer addresses the environmental impact of sediment plumes from dredging and mining operations. The authors propose a Bayesian Optimization- based approach for coordinating autonomous underwater vehicles (AUVs) as a sensor network to monitor plume development.
This section covers underwater archaeology documents, museums, and activities that promote the history of diving and navigation. Our database includes reports and studies by professional archaeologists, UNESCO guidelines, and various national regulations related to these activities, all of which should comply with the United Nations Convention on the Law of the Sea (available in the "Documents" section). There is also a list of museums and contact information for those interested in starting diving but not yet committed to becoming commercial divers. While archaeologists have long relied on recreational divers, exploring deep wreck sites inaccessible to them may require professional diving teams and ROVs, following procedures used in the offshore industry.

Courtesy of Fabrice Pipault Offshore Medical Emergencies: Why "It won’t happen to us" is no longer an option
This article, authored by Dr. Jean Yves Massimelli of Nice University Hospital (France), highlights the widespread lack of medical preparedness, a critical issue in offshore industries. Drawing from a recent personal experience, closely linked to a friend's cardiovascular emergency shortly after returning from work, Dr. Massimelli underscores the urgent need for comprehensive medical emergency response plans (MERPs). The piece emphasizes that appropriate training, adequate resources, and swift response mechanisms are vital to safeguarding offshore workers' health and lives. Furthermore, it argues that neglect in this area, often driven by cost-cutting measures, constitutes a significant safety risk. By spotlighting the ethical and legal responsibilities of employers, the article advocates for a paradigm shift in industry practices, prioritizing medical readiness, strict adherence to safety standards, and accountability, to better protect personnel and prevent preventable tragedies during emergencies.
