hydrocarbon (product) leak detectioncorrosion
under insulation
a different approach
A simple and effective all in one solution.
4
simple obvious

• detect, test and identify any traces of fluid
• on the pipe surface, under the insulation, or
  within the insulation media itself.

independent testing and evaluation Capcis
Limited (UMIST) Manchester University United
Kingdom January 2005 - August 2006 Conclusions
H2Obvious detectors will detect the presence of
fluid in a situation of fluctuating temperatures
and cyclic vaporizing and condensing within the
insulation H2Obvious is able to detect fluid
in the insulation which has not (Yet) reached the
pipe surface
8
recommended fitting Vertical
pipe 1 device fitted at bottom end.
Horizontal pipe 1 device fitted at each and
every insulation joint. (Typically 3 feet
intervals)
9
where to fit? Any new
on/offshore installations As part of fabric
maintenance As part of routine strip and search
Any insulation types (Excluding Glued
Media) Any pipe material Any pipe
diameter Where (currently) the underside of pipe
and insulation are visible
10
interval inspection/testing Any
device at any interval may be unscrewed, a small
amount of water poured in to the unit, await the
LED to commence flashing and the float to
raise. This unit may be dried (Thoroughly) and
refitted. This interval testing does not disturb
the insulation NON - Intrusive Testing
11
replacement when
activated When one or more units are activated,
there is fluid either on the pipe surface under
the insulation or within the insulation media
prior to it reaching the pipe surface. (Fluid in
the unit may be taken away for sampling/testing
for either water hydrocarbons other fluid
product) The insulation in these locations
(Only) will be stripped, remedial works carried
out with new complete devices fitted with the new
insulation.

• fluid sample
• Should the sample be water, the PH can be
  ascertained to determine whether corrosion under
  insulation is of a higher or lower risk at this
  time.
• If the sample is hydrocarbon or other fluid
  product you have an escape and the source of the
  leak is easily identifiable.

13
replacement if inactive In
year 6 the encapsulated units (only) will be
unscrewed, discarded/recycled and replaced
without disturbing the insulation. Giving a
further 5 years assurance of fluid monitoring
hydrocarbon (product) leak detection. NON-Intru
sive Replacement

benefits
24 x 7 x 365 MONITORING
LOCATION IDENTIFIED OF HYDROCARBON RELEASE
COST REDUCTION in repair and maintenance
ROOT CAUSE OF CORROSION indicated before it starts
MAINTENANCE FREE
TESTED ON SITE at any interval
ENVIRONMENTALLY FRIENDLY (Reduces insulation
removal and disposal)
EXTENDS LIFE OF INSULATION
STOPS PROGRESSION OF WATER further from the damage
7 CONSECUTIVE DAYS in electronic indication mode
HIGHLY VISIBLE mechanical indication mode until
removed
ELIMINATES pipe replacement due to CUI
16
major safety business benefits
Reduction/elimination of leaks on hydrocarbon
systems (hence reducing major catastrophic
damage and potential loss of life)
Reduction in fabric maintenance
inspection (hence reduction in incidents and
accidents whilst carrying out maintenance)
Reduction in the incidences of shutdown due to
leakages (hence disrupted production avoided)
Safety issues associated with conducting
subsequent repairs are avoided
Massive overall cost reduction and savings
17
BIG claim
When Fitted Monitored Correctly

Pipes as shown should never need to be replaced
as a result of external corrosion and Hydrocarbon
leakages are easily and quickly identified as a
result of internal pipe corrosion.
