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” These tables can be downloaded by clicking on the picture of the cover

These tables are designed by the Norwegian Diving and Decompression Tables (NDDT).

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 related to diving & ROV operations are accessible on their website or by clicking on this text or the picture of the cover on the side.

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. Clicking on this text or the picture of the cover aside allows access to the list of documents, which includes details of superseded and withdrawn publications.

This document describes a methodology for the use of established Occupational Exposure Limits (OELs) to the hyperbaric setting, taking into account the changes in absolute pressure and exposure duration, such that the resultant Hyperbaric Occupational Exposure Limits (HOELs) represent adequate control for the hyperbaric environment. This document should be associated with the UK HSE document EH40 “workplace exposure limits” (see below). Note that this procedure is purely theoretical.

This document contains a list of hazardous substances and the exposure limits to these contaminants at the surface. The procedures indicated in the document EH75/2 above should be applied for hyperbaric exposures. It is the reason it is displayed here. Note that this procedure is purely theoretical, which is why it is available here instead of on the page “Diving & ROV Procedures”.

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. Because of the wide variability in contaminants, potential exposure levels and other variables, only general guidance and recommended practices are provided.

Between June 2019 and July 2021, five diving fatalities occurred at power-generation facilities in the USA due to differential pressure (Delta-P). For this reason, and at the request of the OSHA's Office of Maritime Enforcement, the Association of Diving Contractors International (ADCI) has organized a team of experts and published this document.

The Irish Health and Safety Authority (the ‘Authority’), with the consent of Pat Breen TD, Minister of State, at the Department of Business, Enterprise, and Innovation, has published this code of practice entitled “Code of Practice for Offshore Diving” in accordance with Section 60 of the Safety, Health, and Welfare at Work Act 2005 (the ‘2005 Act’). This code of practice provides practical guidance as to the observance of the provisions of the Safety, Health and Welfare at Work (Diving) Regulations 2018 (S.I. No. 254 of 2018). This code of practice came into operation on May 1st 2019.

The US Bureau of Reclamation conducts various underwater inspection and maintenance programs that include divers use. This Diving Safe Practices Manual (DSPM) has been developed to ensure employee safety and regulatory compliance. This manual is intended to be the baseline for diving policy and is designed to address the most common Reclamation diving activities.

Authors: Chenyu Zhao a, Philipp R. Thies a , Lars Johanning. This paper couples an inspection class ROV with an autonomous surface vehicle (ASV) via a launch and recovery system (LARS) in a nonlinear numerical model. Operational inspection missions with static and moving targets are modeled for this ASV/ROV system. The paper reports the following distinctive mission profiles: i) pipeline inspection, ii) floating offshore wind turbine (FOWT) mooring line inspection, and iii) circumferential weld surface scan at the FOWT spar.
