Question 1

Which United Kingdom statutory regulation and associated Approved Code of Practice (ACOP) specifically govern offshore commercial surface-supplied diving operations?

The Diving at Work Regulations 1997 and HSE ACOP L103 (Commercial Diving Projects Offshore) The Diving at Work Regulations 1997 and HSE ACOP L104 (Commercial Diving Projects Inland/Inshore) The Health and Safety at Work etc. Act 1974 and Offshore Installations Order 2005 The Pressure Systems Safety Regulations 2000 and ACOP L108

Correct Answer:

The Diving at Work Regulations 1997 and HSE ACOP L103 (Commercial Diving Projects Offshore)

Question 2

What is the critical safety function of the non-return valve (check valve) fitted to the air inlet manifold of a surface-supplied commercial diving helmet or bandmask?

It prevents catastrophic helmet depressurization and squeeze if the main supply umbilical is severed or depressurized It diverts exhaled air directly into the hot water suit to maintain thermal insulation It automatically regulates breathing gas supply pressure to match ambient water depth It isolates the reserve bailout cylinder from the surface supply manifold during normal diving operations

Correct Answer:

It prevents catastrophic helmet depressurization and squeeze if the main supply umbilical is severed or depressurized

Question 3

What is the standard temperature range for hot water delivered from the surface heating unit to a diver's hot water suit during deep offshore surface-supplied diving?

25°C to 30°C (77°F to 86°F) 48°C to 55°C (118°F to 131°F) 38°C to 42°C (100°F to 108°F) 60°C to 65°C (140°F to 149°F)

Correct Answer:

38°C to 42°C (100°F to 108°F)

Question 4

What is the primary function of a Kellems grip (mesh strain relief sleeve) fitted to a diver's umbilical at the harness attachment point?

To serve as a secondary lifting point for recovering an unconscious diver to the deck without a harness To transfer pulling tension from the umbilical directly to the diver's harness, protecting gas line fittings from strain To clamp the hot water hose to the communication cable to prevent thermal heat loss along the umbilical To lock the pneumofathometer tube to the primary air hose to prevent acoustic noise interference

Correct Answer:

To transfer pulling tension from the umbilical directly to the diver's harness, protecting gas line fittings from strain

Question 5

Under commercial diving safety standards, what is the maximum permissible depth measurement tolerance for a pneumofathometer gauge used on an offshore surface control panel?

Accurate within ± 5.0 metres (± 16.4 feet) for dives up to 50 metres depth Accurate within ± 0.25 metres (± 0.8 feet) or 0.5% of full scale Accurate within ± 2.0 metres (± 6.5 feet) across all operating depths Accurate within ± 10.0% of the maximum measurable panel pressure

Correct Answer:

Accurate within ± 0.25 metres (± 0.8 feet) or 0.5% of full scale
