4. Manual Tank Cleaning Health & Safety risks: Confined Space Entry
Labour intensive
Large Crew size
Chemical / Toxic Environments
Time Consuming
Scaffolding (if required)

5. Confined Space HSE Definition…….
“A confined space is a place which is substantially enclosed (though not always entirely), and where serious injury can occur from hazardous substances or conditions within the space or nearby (e.g. lack of oxygen)”
Multiple CSE Risks:
Oxygen deficiency
Toxic gases, fumes, vapors, dust
Activation of equipment
Engulfment
Temperature
Working at heights

6. Confined space fatalities and LWDC (2012-1018)
IOGP Data/ Stats
Fatality to Lost Time Injury Ratios
The IOGP previously reported how the ratio between fatalities and lost time injuries can be
used to identify higher risk categories and activities. For some activities and categories of
incident, when something goes wrong, people may be almost as likely to be killed as they are
to be injured.

From the 15 IOGP incident types, the relative numbers of fatalities and LWDC are of continuing concern:
Transport – Air
Water related, drowning
Confined space

12. Offshore – Platform Case Study UKCS
“During this job 16 pits were cleaned using MI SWACO ATC technology. All pits were cleaned to a high specification with a considerable reduction in cleaning time and slop generation – all without the need for confined space entry which was a key factor as it can be extremely difficult to meet the isolation and permit requirements of a platform…”

ATC Technology Cuts Clean-Up Time in Half
Hours spent in confined space entry decreased by 77%
2,800 bbl column tank –
Split into 8 separate
compartments
Riser deck to tank 394 ft [120 m]
Vertical to main deck 105 ft [32 m]
Washwater required 65 bbl
Barite solids removed 47.6 ton

14. Onshore – PSV cleaning Boat Cleaning
Several Vessel cleaning trials conducted in UK
Permanent installation would be required to optimise ATC
Complete elimination of CSE on vessels using ATC has been achieved in Norwegian Sector
Collaboration of many parties
Focus on CSE elimination over reduction in time
