Combine & conquer
Performance monitoring offers many
challenges. One of them is the multidisciplinary
character of it. State-of-theart
solutions combine Big Data exploited
by Artificial Intelligence techniques
(mostly artificial neural nets), high-fidelity
CFD (computational fluid dynamics)
and advanced sensor technologies
(such as optical measurements).
The required mix of competence comes
often from strategic alliances. Business
alliances and technology alliances both
make the resulting joined forces stronger
in the market.
Information fusion is a term now often
used in performance monitoring.
Come together, data and information.
In »edge computing«, data is processed
at the »edge«, i.e. at or close to the sensors.
For example, several sensors are
compared and outlier readings from individual
sensors are filtered out.
Also, information from different
sources may be compared, e.g. crew observation
of sea state, weather data from
weather providers, acceleration sensors
on-board the ship and simulations of
seakeeping behavior of the ship. The
comparison not only allows filtering
out implausible data, but also points towards
systematic errors in data capturing,
such as ill-calibrated sensors or human
bias in reporting.
ISO 19030 gets harnessed
Performance monitoring can be used
for many applications, e.g. as a base for
contracts between suppliers and owners,
charterers and owners, fuel efficiency
improvement projects, maintenance
trigger, etc. It is gratifying that the wheel
is not reinvented in related initiatives,
but rather ISO 19030 taken as a base and
built upon with specific adaptations for
the purpose at hand.
Johnny Eliasson (Chevron Shipping)
reports on American initiatives, where
a working group of NACE International
supports organizations developing
guidelines for antifouling measures.
This working group (NACE TEG532X) is
open to all, and participation is encouraged,
particularly for ship operators. Intertanko
has a working group, chaired
by Francesco Bellusci (Scorpio Group),
on giving recommendations to its members
concerning performance monitoring.
»There is a big regulatory move
around performance and that matter is
not easy,« summarizes Bellusci. IMO has
a working group on how to assess fairly
and realistically measures to improve energy
efficiency (going well beyond vendor
promises). Noah Silberschmidt (CEO
of Silverstream Technologies) promotes
this initiative: »For us, HullPIC is a vehicle
to both debate and articulate best
practice within industry«. Come together,
regulators and guideline developers.
Good blend of stakeholders
Part of the alchemy of HullPIC is the
blend of operators, coating companies
and developers. This has been reflected
in the program of the conference over the
years. Where the first HullPIC conference
had mainly presentations by developers,
HullPIC 2019 has notably many presentations
where well-known operators
report their experience and concerns,
such as Maersk, Chevron Shipping, or
the US Navy. We also see contributions

on the increase, where companies present
the fruits of joint work, such as DNV GL
with Scorpio Group, NAPA with MOL, or
JMUC and NYK Line.
Let’s hope that this trend continues,
and new friendly alliances are forged during
the conference. We have every reason
to be optimistic. The concept of a boutique
conference, so popular with those
who can attend, has a downside, though.
In response to the limited lecture hall
size and the growing interest, the organizers
imposed a strict rationing of tickets
which left many stakeholders baffled.
»I know it makes us unpopular with
those who cannot participate this year,
but we don’t want to compromise on the
unique quality of HullPIC,« explains
co-organizer Geir Axel Oftedahl (Jotun).

a venue with more capacity next year.
For the ship performance aficionados to
come together …
