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”

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 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).

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?

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.

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.

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.

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.

This document describes an Underwater Hyperspectral
Imager (UHI) deployed on an instrument-carrying
platform consisting of two interconnected mini-ROVs
(Remotely Operated Vehicle) for the
mapping and monitoring of Arctic macroalgal habitats in
Kongsfjorden (Svalbard) during the Polar Night. The mini-
ROV-UHI system is easy to transport, assemble and deploy
from shore, even under the dark, icy and cold conditions
of the Arctic Polar Night. Two persons can operate the
system, keeping operational costs low.

Mini Remotely Operated Vehicle (mini-ROV)
technology has been utilized to perform the
underwater inspection with optimized Risk-based
Underwater Inspection (RBUI) scope for offshore
platforms, which conventionally utilize divers and ROV
supported by Dynamic Positioning Diving Support
Vessel (DPDSV). This technology was introduced by
launching the mini-ROV from the platform deck to
perform General Visual Inspection
(GVI), Cathodic Potential (CP) Survey, Flooded
Member Detection (FMD) & Ultrasonic Thickness (UT)
measurement with customized mini-ROV integration with
another tooling.

The Dutch legislation on working conditions, particularly
concerning hyperbaric labour, has evolved to ensure
safety and compliance in specialized fields like diving and
caisson work. Over time, the Netherlands Labour
Authority has refined its oversight to adapt to changing
workplace risks and practices, resulting in stronger
regulations for these activities and the requirement for
them to be reported to authorities.
