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 papers featured in this edition, we are pleased to highlight the study, "ORCA: AI-powered Autonomous Underwater Vehicle for Subaquatic Exploration”, by Oskar Natan, Wiwit Suryanto, Andi Dharmawan, Rifda Hakimasari, & Zaidan Hakim.
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.
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. Please note that 10 new documents have been added to our database. Click the button below to view the list.
Videos and animations are available in the "Documents" section; they are presentations on equipment, systems, and working practices provided by manufacturers, workers, and various organizations, which can be used to illustrate training courses, toolbox talks, and conferences, or simply for individual learning.

The paper, "Review of excursion procedures used in commercial heliox saturation diving" by Jean-Pierre Imbert, Lyubisa Matity, Jean- Yves Massimelli, Christian Cadieux, Jan Risberg, and Philip Bryson, traces the history and the reasons behind the successive changes that led to the current saturation diving excursion procedures. It also reviews current practices, identifies problem areas, and outlines future perspectives.
"Revised guideline for central nervous system oxygen toxicity exposure limits when using an inspired PO2 of 1.3 atmospheres" by Joseph Hoyt, F Gregory Murphy, Neal W Pollock, Dawn Kernagis, Nicholas Bird, Michael Menduno, John Bright, and Simon J Mitchell is another Key paper that concludes that four-hour exposure to an inspired PO2 of 1.3 atm during a dive poses a low risk of CNS oxygen toxicity, and that the risk of CNS oxygen toxicity can also be reduced by lowering the CO2 retention
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.
avoidance, object detection, and payload manipulation.
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.
The study “The Principle and Application of Underwater Sonar Systems”, by Siyi Wang, Yiduo Wang, and Lang Yin, outlines different sonar types, detailing lower-cost but less precise single-beam systems and more expensive, more accurate multi- beam systems that are better suited to complex seabeds. It also summarizes the future development of sonar systems.
The study “A novel strategy for fast liquefaction detection around marine pipelines: a finite element-machine learning approach”, by Xing Du, Yongfu Sun, Yupeng Song, Wanqing Chi, Zongxiang Xiu, Xiaolong Zhao, and Dong Wang, addresses the challenge of maintaining submarine pipeline stability under dynamic conditions like waves and seismic events.
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 paper “Using surface drifters to characterize near-surface ocean dynamics in the southern North Sea: a data-driven approach” by Jimena Medina- Rubio, Madlene Nussbaum, Ton S. van den Bremer, and Erik van Sebille describes a study where twelve ultra-thin drifters were deployed in the North Sea for 68 days, and closely monitored.
The study "Advancements and Challenges in Floating Photovoltaic Installations Focusing on Technologies, Opportunities, and Future Directions" by Ryan Bugeja, Luciano Mule Stagno, Cyprien Godin, Wenping Luo, and Xiantao Zhang analyzes Floating Photovoltaic (FPV) installations across inland, nearshore, and offshore applications, and their integration with hybrid energy systems.
Laser-derived systems are currently utilized across various industries, including medical, communications, construction, and more. Many studies predict that their use will continue to grow in the coming years as new applications are frequently discovered. This ongoing progress has led to the development of tools based on these principles, such as LiDAR and laser scanners, which are now used for bathymetry, underwater mapping, and underwater imaging. These advancements, particularly in the creation of 3D images, result in impressive visual representations that provide divers and remotely operated vehicle (ROV) pilots with detailed views of their work sites. This not only enhances safety but also improves efficiency, allowing managers and clients to gain a comprehensive understanding of their projects and make informed decisions. The purpose of this brief post is to provide an overview of the physical principles underlying these tools, their classifications, and potential applications. Additionally, it includes a selection of manufacturers and training organizations, along with a comprehensive bibliography and videos, to support a thorough understanding of these tools.
LASER scanners and LiDARs for underwater operations: A resource guide
The gas management chapter in Book #2 of our saturation diving manual has been revised to enhance clarity and understanding. It now includes definitions of gases and their behavior, explanations of the units used for their classification, and calculation formulas. It also describes gas fabrication and mixing processes, along with clarifications on the fabrication and monitoring of gas filtration media. - Click on the cover picture to open it.
United Nations Decade of Ocean Science for Sustainable Development  (UNESCO Ocean Decade 2021–2030)
Since its creation, this website has been guided by three core missions: the free sharing of knowledge with all those passionate about underwater activities, regardless of their financial means; the publication of procedures and studies we consider most relevant to conducting diving and ROV operations safely and efficiently; and a deep commitment to the respect and protection of the sea, during and beyond these activities, in the conviction that life on Earth was born in the oceans, and that failing to protect them responsibly could have lasting consequences for our planet. It was, therefore, a natural step to respond to an invitation from UNESCO staff members, whom I had previously contacted regarding another matter, by submitting our application to the United Nations Decade of Ocean Science initiative. Following a positive outcome, the Diving and ROV Specialists website is now an official contributor to this international program. With that recognition comes the responsibility to raise awareness of the initiative and to encourage its adoption across our industry.
