2:00-5:50pm – Next-generation
inspection and monitoring
technology and techniques for
reducing maintenance costs and
increasing safety
Moderator
Kenji Shimada, Theodore Ahrens Professor
in Engineering, Department of mechanical
engineering, Carnegie Mellon University, USA
2:00pm – Advanced ship inspection
technologies
Pierre C Sames, group technology and
research director, DNV GL, Germany
DNV GL is stepping forward in using advanced
technologies to facilitate smart ship inspections.
Among them are robotic in-water surveys,
drone-supported tank inspections, camera-
based inspection recording and targeting
inspections with fatigue analysis-based data.
All these steps aim at making surveys more
effective and more efficient while also making
the survey and inspection work safer.
2:25pm – Advanced optical-fiber sensor
systems designed for structural
condition monitoring
Tong Sun, Professor of sensor engineering,
school of mathematics, computer science and
engineering, City University London, UK
This presentation will showcase the successful
implementation of advanced optical-fiber sensor
systems designed and developed at City
University London for a variety of structural
condition monitoring both in the laboratory and
in the field. The portfolio of structures monitored
ranges from concrete structures, through marine
propeller and rudder to recent railway current-
collecting pantographs for high-speed trains.
Such advanced sensing technologies have
demonstrated their advantageous features,
compared with their counterparts, such as
immunity to electromagnetic interference,
multi-parameter and multi-node measurement
capability, and small size and light weight.
2:50pm – Inspections through thick
dielectric coatings on marine vessels;
DRDC NDE developments for the Royal
Canadian Navy
Rod McGregor, development engineer,
Defence Research and Development Canada,
Canada
Optimizing maintenance processes to reduce
asset downtime drives advancements in
Non-Destructive Examination (NDE) for all
heavy industry including oil and gas, nuclear,
and military and civilian maritime. Throughout
these industries there have been recent
advancements to allow structural inspections
without the time and cost impact of removal and
replacement of protective coatings like corrosion
protection, sound, or thermal insulation. Defence
Research and Development Canada (DRDC), has
undertaken several developments in this area in
support of the Royal Canadian Navy’s surface
and subsurface naval fleet. Liftoff Pulsed Eddy
Current (LPEC) is a recently patented DRDC
Atlantic metrology device that allows surface
geometric inspections without coating removal
and resulting expense and risk of compromising
the hermetic protection. Substrate topological
damage characterizations is provided by LPEC
technology in combination with commercial
digital metrology equipment (i.e. Laser Tracker).
Field trials of LPEC have demonstrated
significant time and cost savings with acceptable
data accuracy. Also described are other DRDC
NDE developments and their successes with
measurement of critical geometry, and detection
of corrosion, cracks, and water contamination
through thick coatings.
3:15pm – Inspection system for field
equipment
Egil Brekke, project engineer, Westcon Power
and Automation, Norway
Westcon aims to provide a complete inspection
service by implementing modern technology.
Over the past four years, the company has
continually evolved its inspection service, and in
2015 developed a new tablet-based inspection
system. It includes native Android app and cloud
data storage accessed through a web portal, and
enables inspection with tag location, RFID and
photos synchronized to a real-time updated
register where reviews are done and reports
generated. Westcon has developed the software
package in-house and is not dependent on
cooperation of sub-suppliers. The main focus is
inspection of field equipment, in particular Ex
equipment.
3:40-4:10pm – Break
4:10pm – The Ship Inspection Robot (SIR)
Florian Berlinger, graduate researcher,
Harvard University and ETH Zürich,
Switzerland
Jonas Eichenberger, research assistant, City
University of Hong Kong and ETH Zürich,
Switzerland
A prototype robot has been developed with the
purpose of undertaking visual inspections in the
narrow and highly constrained spaces of a ship’s
ballast tanks, between the inner and outer hulls.
It is also intended to be used while a ship is
sailing in order to minimize the time spent in dry
dock and the consequent loss of income to
owners and operators. In this presentation
Florian Berlinger, project manager of the
development team at ETH in Zürich, will outline
the project and the capabilities of SIR.
4:35pm – Using industrial inspection
robotics in the marine sector: Lessons
learned from allied industries.
Ekkehard Zwicker, CEO, GE Inspection
Robotics, Switzerland
As the marine sector looks for smarter, cheaper
and safer ways to conduct inspections in
hard-to-access or hazardous areas, the use of
robotics and remote inspection technology looks
increasingly attractive. These technologies, in
particular robotics, are already routinely used in
the oil and gas and power generation industries.
In this presentation the experience of using
industrial inspection robots in those sectors will
be discussed and useful lessons for the marine
sector highlighted.
5:00pm – Continuous remote monitoring
of watertight integrity
Carl Hunter, CEO and managing director,
Coltraco Limited, UK
As the shipping industry looks for increased
efficiency and automation, continuous remote
monitoring is the technology focus of the future.
One issue is monitoring seal integrity of holds,
hatches, bulkheads, doors and multiple cable
transits during a voyage. There are specific
challenges when it comes to safety and asset
management at sea. One solution that has come
to the fore is to use ultrasonic technology to
continuously monitor the watertight integrity of
these critical components. This enhances
onboard safety management, minimizing risk to
life, cargo and ship. We are here to explain how
ultrasonic technology can be a smart inspection
technology for marine maintenance.
5:25pm – Condition inspection and
characterization of electrical rotating
machines stator wedges
Iker Manzanedo-Saenz, service manager,
Indar Electric, Spain
The marine division of Indar Electric is
developing the knowledge to inspect and
characterize the condition of stator wedges of
electrical rotating machines without rotor
disassembly, allowing inspection to be as short
and non-invasive as possible. The inspection
technique is performed by means of special
tools, tailored to the machine’s constructive
features and the air gap available. Through
inspection results and operating profile analysis,
the condition of stator wedges is characterized in
different levels. For each level, the follow-up
inspections or repair recommendations can be
drawn, optimizing maintenance planning.
