1
00:00:12,578 --> 00:00:15,406
Every year, new pipelines are
built around the globe

2
00:00:15,408 --> 00:00:17,945
for the purpose of transporting
huge volumes

3
00:00:17,946 --> 00:00:21,176
of gas, oil, water,
and other chemicals.

4
00:00:21,178 --> 00:00:23,235
During pipeline construction

5
00:00:23,236 --> 00:00:26,288
pipes are generally girth-welded
together on-site,

6
00:00:26,290 --> 00:00:29,291
using automated
welding systems.

7
00:00:29,293 --> 00:00:30,740
Before the pipe is coated,

8
00:00:30,741 --> 00:00:32,741
buried, or laid onto the seabed,

9
00:00:32,743 --> 00:00:35,676
each weld needs to be
nondestructively tested

10
00:00:35,678 --> 00:00:38,078
to ensure its integrity.

11
00:00:38,080 --> 00:00:39,526
The Olympus PipeWIZARD

12
00:00:39,528 --> 00:00:42,245
is a phased array system
dedicated to the inspection

13
00:00:42,246 --> 00:00:44,715
of construction pipeline girth welds.

14
00:00:44,716 --> 00:00:46,463
It is specifically designed

15
00:00:46,465 --> 00:00:48,830
to work in extreme
environments.

16
00:00:48,831 --> 00:00:50,673
From cold Siberian regions

17
00:00:50,675 --> 00:00:52,741
to hot Middle-Eastern deserts,

18
00:00:52,743 --> 00:00:55,296
in humid, salty, or dry conditions,

19
00:00:55,298 --> 00:00:57,600
the system has been extensively tested

20
00:00:57,601 --> 00:01:01,231
and has proven resistant to
vibration and shocks.

21
00:01:01,233 --> 00:01:03,678
It is used in some of the
largest onshore

22
00:01:03,680 --> 00:01:05,995
and offshore
pipeline construction projects

23
00:01:05,996 --> 00:01:07,600
throughout the world.

24
00:01:07,601 --> 00:01:10,016
The instrumentation is
sealed and ruggedized

25
00:01:10,018 --> 00:01:12,018
to withstand the often
harsh conditions

26
00:01:12,020 --> 00:01:15,075
of the areas where
pipelines are installed.

27
00:01:15,076 --> 00:01:17,478
Hundreds of operators have been
trained in the field

28
00:01:17,480 --> 00:01:19,726
on the PipeWIZARD and
millions of welds

29
00:01:19,728 --> 00:01:22,723
have been inspected using this system.

30
00:01:22,725 --> 00:01:24,441
Various techniques can be used

31
00:01:24,443 --> 00:01:26,361
to inspect pipeline girth welds,

32
00:01:26,363 --> 00:01:28,395
but automated ultrasonic testing

33
00:01:28,396 --> 00:01:30,253
with zone discrimination provides

34
00:01:30,255 --> 00:01:33,671
several advantages
over other NDT techniques.

35
00:01:33,673 --> 00:01:35,863
Radiography and ultrasonic testing

36
00:01:35,865 --> 00:01:38,436
are the most common volumetric
inspection methods

37
00:01:38,438 --> 00:01:40,901
for newly constructed pipelines.

38
00:01:40,903 --> 00:01:42,713
The ultrasonic method is preferred

39
00:01:42,715 --> 00:01:45,158
over RT eliminating the
radiation hazard

40
00:01:45,160 --> 00:01:47,640
for those working
in the inspection area.

41
00:01:47,641 --> 00:01:49,855
It provides test results immediately

42
00:01:49,856 --> 00:01:52,270
and allows for precision defect sizing

43
00:01:52,271 --> 00:01:54,955
particularly in the thru-wall plane.

44
00:01:54,956 --> 00:01:56,880
When compared with radiography,

45
00:01:56,881 --> 00:02:00,510
other advantages of phased array
ultrasonic testing include:

46
00:02:00,511 --> 00:02:02,376
High probability of detection (POD),

47
00:02:02,378 --> 00:02:05,333
especially for cracks
and lack of fusion

48
00:02:05,335 --> 00:02:08,968
Better flaw detection
and sizing accuracy

49
00:02:08,970 --> 00:02:11,053
Short inspection-cycle time

50
00:02:11,055 --> 00:02:12,941
and high production rates

51
00:02:12,943 --> 00:02:15,376
Use of engineering critical
assessment (ECA)

52
00:02:15,378 --> 00:02:18,756
acceptance criteria for
depth and height sizing

53
00:02:18,758 --> 00:02:22,520
Elimination of radiation
hazards and licensing

54
00:02:22,521 --> 00:02:25,673
No chemical or waste materials

55
00:02:25,675 --> 00:02:27,703
Immediate analysis for real time

56
00:02:27,705 --> 00:02:31,411
production control and
reduced reject rates

57
00:02:31,413 --> 00:02:33,453
and setup and inspection reports

58
00:02:33,455 --> 00:02:35,628
in electronic format

59
00:02:35,630 --> 00:02:38,123
The PipeWIZARD provides
code-compliant inspections

60
00:02:38,125 --> 00:02:43,105
for ASTM E-1961 and API 1104.

61
00:02:43,106 --> 00:02:45,848
The system also provides compliance
for the offshore

62
00:02:45,850 --> 00:02:50,660
AUT standard DNV-OS-F101.

63
00:02:50,661 --> 00:02:53,416
In manual welding,
the weld bevel is angled

64
00:02:53,418 --> 00:02:56,093
at approximately thirty degrees.

65
00:02:56,095 --> 00:02:58,611
A phased array
pulse-echo setup is suitable

66
00:02:58,613 --> 00:03:01,438
because the ultrasonic beam
hits the side wall

67
00:03:01,440 --> 00:03:03,858
near perpendicular.

68
00:03:03,860 --> 00:03:05,421
In automated welding,

69
00:03:05,423 --> 00:03:07,840
typical of most pipeline
construction projects,

70
00:03:07,841 --> 00:03:09,815
the weld bevel is angled higher

71
00:03:09,816 --> 00:03:11,711
at approximately 5 degrees

72
00:03:11,713 --> 00:03:14,786
making pulse-echo
inspections impossible.

73
00:03:14,788 --> 00:03:16,610
Because of flaw orientation,

74
00:03:16,611 --> 00:03:18,891
a phased array pitch-catch technique

75
00:03:18,893 --> 00:03:22,163
is better suited for
detection and sizing.

76
00:03:22,165 --> 00:03:24,806
The PipeWIZARD software,
instrumentation,

77
00:03:24,808 --> 00:03:27,460
and scanner are
specifically configured

78
00:03:27,461 --> 00:03:31,508
for the zone discrimination
pitch-catch inspection technique.

79
00:03:31,510 --> 00:03:32,963
When using this method,

80
00:03:32,965 --> 00:03:35,271
a specific ultrasonic beam is created

81
00:03:35,273 --> 00:03:37,273
for each section of the weld.

82
00:03:37,275 --> 00:03:39,026
In a single line scan,

83
00:03:39,028 --> 00:03:41,455
the weld is divided in multiple zones

84
00:03:41,456 --> 00:03:44,751
and each one
is individually inspected.

85
00:03:44,753 --> 00:03:47,771
The PipeWIZARD uses multiple
techniques in tandem

86
00:03:47,773 --> 00:03:50,930
to ensure complete
coverage of the weld.

87
00:03:50,931 --> 00:03:53,593
Time-of-flight diffraction
detects porosity

88
00:03:53,595 --> 00:03:56,286
and vertical cracking in the volume,

89
00:03:56,288 --> 00:04:00,075
Pitch-catch detects lack of fusion
in the weld bevel

90
00:04:00,076 --> 00:04:04,326
and pulse-echo detects flaws
in the root and cap.

91
00:04:04,328 --> 00:04:06,623
During acquisition, a B-scan

92
00:04:06,625 --> 00:04:09,570
displays the root and the
volume of the weld

93
00:04:09,571 --> 00:04:11,596
and the coupling status is also

94
00:04:11,598 --> 00:04:14,168
continually monitored on the screen.

95
00:04:14,170 --> 00:04:17,106
A comprehensive report is
automatically generated

96
00:04:17,108 --> 00:04:19,883
in electronic format for each weld.

97
00:04:19,885 --> 00:04:22,783
The simple design
and color-coded graphics

98
00:04:22,785 --> 00:04:27,868
provide fast analysis
and easy comprehension.

99
00:04:27,870 --> 00:04:30,130
The PipeWIZARD system is designed for

100
00:04:30,131 --> 00:04:35,661
high productivity in
pipeline construction projects.

101
00:04:35,663 --> 00:04:37,868
Training is available for the system

102
00:04:37,870 --> 00:04:40,425
and Olympus is firmly
committed to providing

103
00:04:40,426 --> 00:04:42,825
the highest level of service
to its customers

104
00:04:42,826 --> 00:04:45,548
no matter where they are in the world.

105
00:04:45,550 --> 00:04:47,875
