Company manuals are part of the company's management system and are mandatory. However, writing and updating such documents requires significant time, financial resources, and expertise: - It is essential to involve individuals who are accustomed to conducting such work to ensure that the published documents are fully compliant with national and international standards and based on relevant scientific and technical publications. - The cost of creating manuals is not fully controllable because their design is based on knowledge and reference documents that are sometimes not easy to find, organize, and explain. For these reasons, extra time is often required to write these documents, which must be easy to read and comply with both national and international regulations. This research and compilation time is usually very difficult to evaluate. - A system of updating must be in place, as the competent bodies regularly review their policies. Multinational corporations can implement the creation of dedicated safety and technical documentation without a significant impact on their resources, as their turnover is high enough to make this expense a relatively small part of their operating budget. In contrast, small organizations may find that creating such documents incurs a significant cost relative to their income. Additionally, employees assigned to this work are typically not specialized in it and cannot be utilized for projects where they have more skills. Consequently, there is a risk that, due to a lack of expertise, time, and resources, the documents produced may not address all the risks to which these companies’ personnel are exposed and may not fully comply with the regulations of the countries in which the company operates. This can lead to loopholes being exploited by unscrupulous individuals in the event of an accident, or the documents being rejected by the competent bodies responsible for evaluating them and subsequently by the customers themselves. To help small companies solve this problem at a reduced cost, CCO Ltd. has compiled a series of diving manuals based on recognized appropriate national and international standards and guidelines, as well as relevant scientific and technical documents. As a result, these manuals comply with most national and international regulations and can be utilized in part or in whole to: - Create company manuals from scratch. - Reinforce existing documents. In addition to the reasons outlined above, the purpose of providing these documents is to offer accurate references to people engaged in diving operations, who may include, but are not limited to: - Company managers - Project managers - Offshore construction managers - Diving & ROV superintendents - Diving & ROV supervisors - Divers & ROV pilots - Client representatives - Every person interested in diving and ROV procedures Of course, the responsibility for their use by companies lies entirely with those who choose to adopt them. These documents are available free of charge from the Diving and ROV Specialists website and by clicking on the images of the descriptions below:

These documents have been written with the consideration that technical documents must be pleasant to read. Therefore, efforts have been made to write texts that are accessible to people not familiar with commercial underwater operations: - New terms are explained in the text, rather than in a glossary at the beginning of the document. - Acronyms are used sparingly and are explained in the context in which they appear. - The guidelines from competent bodies are explained but never modified. Additionally, many official guidelines are included in the manuals to avoid the need to search for them in another document. - Drawings, charts, and photos are provided to reinforce each topic discussed.
