Fusion software helps combine different types of data to create accurate digital models of underwater environments and assets. In fields like geospatial engineering and inspection, it integrates tools like photogrammetry, laser scanning, and CAD applications into one unified model. This process leads to better representations of submerged structures, aiding collaboration and informed decision- making, and ensuring safety during underwater operations. This article should be considered a complement to the previous ones on SONAR, photogrammetry, and LASER-derived systems. Like those earlier pieces, it is written solely to raise awareness of these technologies. It is worth noting that, as demand for digital data grows, underwater operations become more complex. Therefore, the ability to seamlessly fuse these datasets will soon shift from a luxury to a necessity for the safe, efficient, and cost-effective marine operations clients demand. In addition to describing the purpose and advantages of this technology, this article lists applications suitable for various scenarios, providing the functions of each, as well as the minimum required hardware performance, ergonomics, prices, and technical support.
Fusion applications - A resource guide
"Diving and ROV Specialists" participates in the United Nations Ocean Decade initiative. However, because of the range of missions it encompasses, the United Nations has become a very complex organization, which the public finds hard to understand in terms of rationale and functions. This is likely linked to communication that has not clarified the organization's various missions to the public, partly because it uses legal specialists who communicate in legal vocabulary typically used in courts, which people unfamiliar with it find difficult to understand. It is also linked to the fact that the United Nations was deliberately built as a system rather than a single body, acting as a political core (the Charter organs) surrounded by a constellation of specialized agencies, each with its own founding treaty, its own governing assembly, and its own procedures for converting agreements into documents. While the founders considered this architecture the best way to fulfill its missions, the resulting complexity requires explanations to provide a relevant picture of the organization's impact on commercial underwater operations, which is the purpose of this article.
Discussion August 2026 United Nations instruments and  diving and ROV operations United Nations Decade of Ocean Science for Sustainable Development  (UNESCO Ocean Decade 2021–2030)
Our website is dedicated to the free dissemination of knowledge for those passionate about commercial underwater activities. This includes publishing procedures and studies that we consider most relevant for conducting diving and ROV operations safely and efficiently, and for respecting and protecting the marine environment, both during and beyond these operations. This approach led to our inclusion in the UN Decade of Ocean Science for Sustainable Development, an initiative managed by UNESCO. To support this program, we've added this section to summarize the initiative's purpose and share the latest news on its progress, with the goal of raising awareness and encouraging its adoption across our industry. Other Ocean Decade participants are invited to submit content for this section, based on the criteria outlined in the "Publish a text" subsection of our "About Us" page, which align with UNESCO's goals.
