Why this website? Allow me to introduce myself: I was born into a military family in Dakar on February 1st, 1957. I have been diving since 1985, initially as a recreational diver and then as an instructor. After several years of high-level carpentry work, where I created and restored frames for several historical monuments in Brittany, my country of origin, I started my commercial diving career in 1995, became a saturation diver in 1998, and a diving supervisor in 2005. I qualified and held the positions of ROV pilot-technician, diving supervisor, superintendent, offshore construction manager, and client representative roles in Southeast Asia, where my family and I are currently based.  I founded CCO Ltd. in 2014. I began writing diving manuals and referenced technical documents about manned and unmanned underwater interventions. My original manuals and thematic studies are obtainable from www.diving-rov-specialists.com, free of charge. They have earned recognition from scientists, engineers, supervisors, and divers. My aim consists in providing the Diving Community with highly reliable information they can utilise for designing and writing their own diving manuals, procedures, training & familiarisation programs, drills scenarios, working instructions, and terms of reference for audits and inspections. I want you, as the reader, to easily identify the scientific and technical references my documents are based upon. All these references are also available from the website. I do not provide peremptory statements. Instead, I want to enable you to access the background that supports a hypothesis, a recommendation, a rule or an industry practice; I want to help you use your critical thinking, hence enabling you to rely on peer-reviewed information which I strive to make immediately accessible here. I believe in deference to expertise, apprenticeship, dedication to the transmission of knowledge, training, mentoring, and, ultimately, “real safety”. I launched www.diving-rov-specialists.com in 2021 and I have been maintaining it through all these years with the support received from experts of various domains such as my friends Jean Yves Massimelli, Jean Pierre Imbert, and many others who support this project according to their means and free time. I welcome your comments, rants, and suggestions. I am eager to publish your viewpoint, your chronicles, and your valuable experiences. Although I created it “www.diving-rov-specialists.com” is your website.  In addition to the above, please consider the following, which may address some questions you may have: • "Diving and ROV Specialists" occupies a unique position in the commercial diving industry: - Professional organizations distribute their guidelines but maintain no broader repository. They do not curate scientific literature from external researchers, compile technical documents from diverse sources, or provide directories of equipment manufacturers and service providers. This limitation is logical, as their primary mission centers on member advocacy rather than comprehensive knowledge dissemination. - Academic document-sharing platforms take the opposite approach: they archive research papers but offer little else. Users must already possess the expertise to identify relevant studies, evaluate their applicability, and synthesize findings independently. These platforms provide no contextual guidance no curated collections addressing specific operational challenges, and no integration with practical resources like equipment suppliers or training providers. The "Diving and ROV Specialists" concept bridges this gap by combining curated scientific literature, technical handbooks, practical articles, and industry resources in a single accessible platform. This integrated approach serves both experienced professionals seeking a deeper understanding and newcomers navigating an environment unfamiliar to them. • "Diving and ROV Specialists" was not created to compete with existing professional diving and ROV organizations. Rather, it is an essential complement to them, offering references and links that, as mentioned above, they do not provide to the public. In addition, we are open to exchanges with them when required, and, like any individual, they can access our database, contact lists, handbooks, diving management studies, and thought-provoking articles, all available for consultation and reuse as needed, provided that the authors of the papers, including us, are credited. • “Diving and ROV Specialists” also does not compete with existing editors of technical and scientific papers. Instead, we do our best to support them by promoting their latest publications, and indicating the links where their free and paid documents can be downloaded (see in Section “News”). In addition, although these editors offer databases of millions of documents for some of them, it should be noted that these databases contain numerous categories of publications, of which studies related to diving and ROV activities are far from representing the majority. We can also consider that this is the same for document-sharing websites, we also support and where I publish some of my documents. On our side, we focus solely on papers related to underwater activities and strive to group them into one place. Therefore, we can conclude that “Diving and ROV Specialists” is a sharing hub that, in addition to grouping documents. provides links to editors, as our database is designed to assist people rather than compete with editors. This approach has been recognized as relevant by leading diving medical organizations such as the previously mentioned SPUMS and EUBS, which is why they allowed us to redistribute their documents, an exceptional concession, as they usually forbid it. A similar process is underway with other organizations. • To answer the question of why we store documents in our database instead of providing links to their initial storage places, this process offers the advantage that the links to documents are more direct and under control, considering that links to external databases are sometimes broken or the organization managing the external database can stop its activities, as it has been the case with "The Rubicon Foundation", a trusted source of documentation that suddenly dieapeared with all the papers stored in it. Please keep in mind that, for these reasons, most document sharing websites operate in this manner. It is also worth noting that, until now, the documents in our database have been under Creative Commons (CC) licenses or similar schemes, and have mainly been provided by their authors. It is therefore evident that the authorizations granted by EUBS and SPUMS alter how we will manage our database sources. • "Diving and ROV Specialists" provides handbooks specifically designed for diving and ROV personnel, of which I am the primary author. This work draws on my 15 years of experience as a document writer, along with my background as a diver, diving supervisor, offshore construction manager, and client representative, as well as on our database, to which these documents refer. While we plan to expand this "vulgarization" beyond manuals, we do not intend to edit purely scientific or engineering papers. As noted above, we support editors of scientific and technical articles, and producing such documents requires specific competencies and organizational structures. We therefore consider it more appropriate to focus on what these organizations do not provide, and that will be useful to the entire underwater workforce community. • As suggested previously, “Diving and ROV Specialists” operates ethically and independently from other organizations involved in commercial diving and ROV activities, even though we try to have good relationships with them. As a result, we focus solely on the technical, scientific, and safety aspects of the documents. While we congratulate the authors of some documents that we consider key papers by highlighting them on our home page, or presenting them in the section “Food for Thought”, we also do not hesitate to criticize publications we deem inappropriate. The reason is that we operate as specialists, and therefore, we cannot promote inadequate practices. We do it scientifically and impartially. However, even justified criticism often generates anger from the promoters of the targeted documents. Therefore, despite what is explained above, this website may interfere with the interests of individuals and pressure groups, potentially resulting in unjustified criticisms coming from them. When I speak of unjustified criticisms, I emphasize that none of the publishers of documents we have challenged have been able to oppose the constructive arguments we have used. Yours, sincerely.  Christian Cadieux.
