Diving & ROV Procedures 2019 - Now

These diving tables are the result of COMEX studies and were first published by the French ministry of labour in 1992 under the name MT-92. There is no change of the initial tables in the new version published in 2019, except that the medical table COMEX CX 18 has been added to the CX 12 and CX 30. The main changes of French regulations 2019 are with the divers’ certification system. These tables remain one of the best decompression model, and are among the most simple to implement. Note that this document is edited in French. However, an English version of the MT92 is available in the folder “Old Tables” Click on the image of the cover to open it.

International Association of Oil and gas producers (IOGP) is an organization that defends the interest of some multinational petroleum companies such as Shell, Exxon, BP, Total, and others. This organization acts as a group of pressure to impose the point of view of its members to the contractors working for them and try to influence national and international safety organizations to establish its members in a dominant position. Their publications on diving and ROV operations are of a low technical level. They can be accessed on their website or by clicking on this text or the image of the cover.

NORMAM-15/DPC procedures propose saturations and air diving procedures. The saturation procedures are a development of the COMEX procedures and are considered among the best ones for diving operations up to 350 m for which they have been specifically developed. These procedures are those selected in the “saturation diving handbook” Diving & ROV Specialists. They are also explained in the diving study #5 CCO Ltd, “Implement NORMAM-15/DPC saturation diving procedures”. Both documents are available in Documents/Documents Diving & ROV Specialists. Note that NORMAM-15 DPC is recommended by the Diving Medical Advisory Committee (DMAC) for deep saturation diving operations. This book is in Portuguese

The work of the Diving Medical Advisory Committee is reflected in its series of guidance notes concerning various aspects of diving and diving medical practice. All current guidances aer available for download free of charge.

Year of publication: 2019 Author: Francis Hermans Abstract: Whether on the surface or underwater, to burn and turn into iron oxide, a metal (iron) needs some supply of pure oxygen. In order to obtain maximum efficiency, most manufacturers of cutting material as well as some cutting manuals, advise to use an oxygen purity of at least 99, 5 % and predict that it is impossible to cut as soon as the purity of oxygen becomes equal to or less than 95%. Is it a myth or a reality?

Year of publication: 2019 Author: Francis Hermans Abstract: This document describes various tests carried out in freshwater to check the flammability and/or explosiveness of the residual gases produced during cutting with exothermic electrodes. The results show that, contrary to what is generally thought, the gases rising to the surface contained a relatively low percentage of hydrogen which was well below the lower limit of flammability. At first glance, and subject to further study, it seems that the origin of the rare underwater explosions related to exothermic cutting in freshwater is not due to an excess of hydrogen but rather to a combustible gas from another source.

Year of publication: 2021 Author: Francis Hermans Abstract: Statistics show that fatal accidents due to explosions linked to underwater cutting are relatively high. Various techniques (diamond wire, hydraulic shears, and hydro- abrasive jet) exist and are already used. Nevertheless, these tools cannot be used in all situations, and therefore thermal cutting is not yet ready to be stopped. This document, which has no scientific vocation, explains the causes, effects, and consequences of these accidents to prevent them from happening.

Year of publication: 2020 Authors: Joseph H. Tarnecki, William F. Patterson III Abstract: Instruments are often deployed at depth for weeks to years for a variety of marine applications. In many cases, divers can be deployed to retrieve instruments, but they are constrained by depth limitations and safety concerns. Acoustic release technology can also be employed but can add considerable expense, and acoustic releases will at times fail. To answer such problems, the authors explain a simple method that utilizes a commercially available mooring hook integrated with a mini remotely operated vehicle to attach lines to instruments deployed on the seafloor, which can then be winched to the surface.

This manual, that supersedes the rev. 1 published in 2008, provides the US Navy general guidance and basic procedures for diving in contaminated water.
