This document summarizes information about diving operations for the Concordia wreck removal project. It discusses that diving operations are between 6 and 35 meters deep using surface supplied diving techniques. Over 15,000 dives have been performed since October 2012. Medical assistance is provided with 430 personnel and 11 hyperbaric chambers involved, treating an average of 130 health issues per month, which were mostly minor with diving accidents making up 10% of cases. Standards and regulations for commercial diving are also discussed.

Diving operations
The keel of the ship is 30 meters deep.
Diving operations are between 6 and
35 meters deep.
The technique used is the Surface
Supplied diving.
From October 2012 to present, 15199
dives were performed
For decompression the Titan uses tables USN rev 6 (2008),
with surface decompression on oxygen (11000 dives)
The Micoperi uses French tables “Travaux en Mileu
Hyperbare” (June 1992) with in water decompression
breathing Oxygen Enriched Air (4000 dives)

Medical assistance
• 430 personnel (180 divers) and 11 hyperbaric chambers
are involved.
• There was an average of 130 health interventions per
month.
– traumatic injuries to surface personnel or to divers (in the water);
medical cases such as anaphylaxis, myocardial infarction as well
as primary health care (colds, flu, stitches) were 90% of the
medical team’s activity.
– Diving accidents were the other 10% of medical activities
• the appropriate training of health personnel in
service on commercial diving sites is recommended

The standard (UNI 11366) defines criteria and methods
for commercial diving and hyperbaric professional
activities, gears and equipment features and
professional requirements of the people involved, to
assure safety and health of the workers during their
activities.
The UNI 11366 reflects the guidelines published by
IMCA
The UNI 11366 has been implemented (2012) as the
law of the State
UNI - Italian Organization for Standardization

11. Aims and approach
The good practices are aimed to divers who study
and monitor the quality of coastal marine
environments.
The good practices are intended to provide a safety
framework through the identification of
responsibilities, applying correct procedures and
adequate training, fulfilling the requirements of the
European Scientific Diving Panel.
