50. TYPES OF STORAGE
PRESSURISED STORAGE
-Above ground bullet for smaller capacity
-Mounded bullet : for Medium capacity
-Sphere : Conventional and for medium
capacity.
-Cavern Storage in underground rocks:
High capacity.

51. WHY MOUNDED BULLETS
Mounded bullets have a sand cover
around, which can take external
impacts.
Chances of BLEVE(boiling liquid
expanding vapour explosion) are
extremely remote.
Chances of “Domino Efect” due to fire or
explosion in adjoining area are virtually
eliminated.
Protection From Extreme of ambient
Temperatures.

52. WHY MOUNDED BULLETS
Reduced firewater requirement
for fire fighting.
Enhanced Security against
sabotage.
Optimum Land use due to
reduction of separation
distance.

53. DESIGN ASPECTS –MOUNDED BULLET
Horizontal placed Cylindrical Vessel(s)
are used for mounded storage.
Design Code –ASME SEC VIII or BS-
5500
Design Temperature –27
0
C to +55
0
C
Design Pressure –14.5 kg/cm
2
g vapor
pressure at top of the vessel.

54. DESIGN ASPECTS –MOUNDED BULLET
Corrosion Allowance –1.5 mm
(minimum)
Radiography –Full
Stress Relieving –100% irrespective of
thickness
The dimensions (diameter & length) of
the vessel shall be decided based on the
site condition, soil mechanics nd type of
fabrication facilities available.

55. DESIGN ASPECTS –MOUNDED BULLET
The external surface of the vessels, which is
covered by mound should be protected from
corrosion.
-By provision of external surface coating
-By Cathodic Protection (Impressed current
system)
-For mounded bullet used for Refinery Service,
due to presence of caustic environment and
H
2S, the internal portion of vessel should be
coated with suitable anticorrosive coaing.

56. DESIGN ASPECTS –MOUNDED BULLET
For refinery Service –Since H2S
presence cannot be ruled out in the
Refinery. Material in line with design
code ASTM A516 Gr.60 or equivalent
shall be used.
For Marketing installation : Where H2S
is not present, ASTM A 516 Gr.70(IT) or
SA 537 C II (IT) or BS:5500 or
equivalent material shall be used.

57. DESIGN ASPECT –SEPARATION DISTANCE
Between Mounded bullet and property
line, boundary, group of buildings not
associated with LPG plant shall be 15
meter.
Between Mounded bullet and Fire water
pump house/or fire water tank shall be
30 meter.
Between Mounded bullet and other
(other than LPG pump/compressor
house) facility associated with LPG
plant shall be 15 meter.

58. DESIGN ASPECT –SEPARATION DISTANCE
A road of minimum 3.5 m width shall be
provided around the mound for
movement of earth / fire fighting
euipment.
The minimum inter-distance between
the edge of the vessel(s) in a mound not
be less than 1.5 m between the vessels
having diameter of 2 m and 2 m for all
other cases.

59. PUMPING FACILITIES –MOUNDED
BULLETS
IN-TANK PUMP
Cost increases for multiple bullets
Leaves dead volume inside bullet
Needs to be removed for maintenance
Lower operating experience
Considered marginally better from
safety point of view

60. PUMPING FACILITIES –MOUNDED
BULLETS

Wide range of experience in india
Provision of draining on the
suction piping

61. INSTRUMENTATION –MOUNDED
BULLETS

shall be provided on first flange on liquid
line(s) from the vessel either from bottom or
top as per the design consideration. There
shall not be any other flanges, or any other
tapping upto the ROV
In case of liquid line from the bottom of the
vessel, the minimum distance of 3 metre from
the vessel to ROV shall be maintained.

62. INSTRUMENTATION –MOUNDED
BULLETS
The top of the vessel shall be
provided with nozzle with nozzle
for the vapour outlet and re-
circulation, which shall also be
pro0vided with fire safe ROV

settlement of the mound/vessel by providing
permanent reference point. A minimum of
three reference points shall be provided to
ascertain uniform/differential settlement. The
settlement of vessel shall be inspected at least
on half yearly basis.
