Hazardous areas
Hazardous areas are those areas where there is a risk (continuous or
intermittent) of the presence of a flammable atmosphere arising from drilling or
well-testing operations.
Lloyd’s Register Energy - Drilling
Hazardous areas
Why we need them
We drill for Hydrocarbons
We hope to find them
We are expecting them

TO PROTECT OUR ASSET
The asset has 4 components:
• The steelwork
• The people
• The peoples’ knowledge / experience
• The reputation

Hazardous areas
The gas we expect
This table shows US gas composition
Natural gas is 90+% Methane
Lloyd’s Register Energy - Drilling
Hazardous areas:The gas we expect
With Natural gas being 90+% Methane.
The asset is designed to protect against Methane.
Drilling is lucky; we only have 1 flammable gas to consider.
Refineries and chemical plants need to consider the gas / flammable vapor and
then decide the equipment protection standard.
Drilling gas is Methane.

Protection
Remove the fuel?
Remove the heat?
Take away the oxygen?
Lloyd’s Register Energy - Drilling
Hazardous areas
Protection
• separate the flammable atmosphere from any hot surface
• reduce possibility of spark or heat
• contain any ignition of a flammable atmosphere inside the enclosure
• reduce power of the spark to a point it has insufficient power to ignite the
flammable atmosphere

The hidden danger and the unseen risk
Concentrate on two
• Exd
• Exp
Why ?
Historically we see too many faults with these two
Lloyd’s Register Energy - Drilling
Two protection types
Exp - Pressurisation
The system is only safe once purged and remaining at a pressure above the
outside pressure.
An alarm needs to be fitted for loss of pressure.
Separate the gas from the hot components
Break the fire triangle by separation.

Two protection types
Exd Explosion Proof
An Explosion IS Allowed INSIDE the
enclosure.
Maintained Flamepaths
All bolts secured
NO ignition OUTSIDE

Two protection types
Exd Explosion Proof
Exd contains the explosion
A pipe flange contains the pressure
A pressure test on a pipe
A drip on a pipe is seen
Any comparison.

The hidden danger
The driller is a villain
Smoking on the floor!
The electrician is a Hero
For keeping the rig drilling, working fine
Lloyd’s Register Energy - Drilling
Risk
Smoking is a flame
It can ignite gas only when
smoking is occurring
Time: Only when smoking.
Severity: 5
Likelihood: 1
RISK 5
Lloyd’s Register Energy - Drilling

Electrical enclosure with
sparking /arcing devices
and no pressure protection
will ignite gas.

The hidden danger
Is the Driller still a Villain?
By smoking on the floor!
Is the Electrician still a Hero?
For keeping the rig drilling working fine but in a dangerous way
•

•
7 days a week
•
52 Weeks a year
The classic 24-7 but unseen?

The hidden danger

In full view of everyone.
Green is good
Red is danger
Now who do you point the finger at?
Lloyd’s Register Energy - Drilling
Risk
Exd enclosure
Missing bolts and
damaged flamepath
Will ignite gas OUTSIDE.
It is still working
Time: Constantly
Severity: 5

RISK 20

RISK
Your asset is protected?
The equipment we install is good quality!
The equipment is fully tested / certified!
The system is designed is by qualified people?
The installation is by highly trained and competent people?

RISK
It should be remembered:
It is the engineer and the electrician who make things safe.
Not pieces of paper and certificates.

The Hidden Danger
A short introduction to the hidden dangers of Ex equipment
What was first thought of as a major danger ?
What was thought to be safe?
Before I recap
Any questions?
Lloyd’s Register Energy - Drilling
RECAP
Working is not the same as Safe
Exp needs to have the alarm tested and any pressure gauge visually checked
Exd needs all bolts in and secure.
Lack or poor maintenance will give a false sense of security
Ex equipment is Not Fit and forget
Lloyd’s Register Energy - Drilling
RECAP
Working is not the same as Safe
Maintenance personnel need training to keep YOUR asset Safe
Some of the Ex equipment gives you an impression of safety.
Thank you

Marine
We are dedicated to supporting innovation in shipping
We are a leading provider of marine classification services around the world,
helping to ensure that internationally recognised quality standards are
maintained throughout the life of a vessel from construction to decommissioning.
But we provide much more than traditional classification surveying services.
There is an increasing need for the provision of sophisticated risk management
and support to shipowners and ship managers. We provide management
systems, fuel oil quality testing, environmental services, vetting and training
products and services to support our marine clients.

Facts about Marine…
In 2011 we classed 413
new built vessels with a
total carrying capacity of
20,264,810 deadweight
tonnage and an overall
length of 65,643m
We class a
market-leading
45% of the global
cruise fleet
100 years ago the first
diesel-engine merchant
ship, the Selandia,
entered service. Today
we are researching the
new fuels of the future as
the shipping industry
looks to reduce
emissions and
environmental impact.
The phrase 'A1', which
has passed into
common usage meaning
'first rate - the very
best', originates from its
use as the highest
classification awarded to
ships by Lloyd's
Register.
