Norwegian Cruise Line and DTA
By rolling out Eniram’s Dynamic Trimming Assistant across its fleet of cruise ships,
Norwegian Cruise Line is both saving money and reducing its carbon footprint.
Customer overview
The Norwegian Cruise Line (NCL)
operates the youngest fleet of cruise
ships on the planet and aims to offer
the highest quality of accommodation
combined with greater flexibility and
freedom for passengers on board.
Based in Miami, USA, it operates
ten ships and specializes in cruises
between destinations in Europe, North
America, South America, Hawaii and
the Caribbean.
Like all cruise ship operators, NCL
has a large expenditure on fuel. The
company knew that the position of its
ships in the water had a big impact on
fuel consumption and started to seek
out ways to better monitor the drag
and trim (floating angle) of its vessels.
Captain Bjorn Ove Hansen, Director
of Nautical Operations at Norwegian
Cruise Line, explains: “During day
time, it is possible for experienced
vessel officers to determine if the trim
is close to correct by watching the
wake and propeller wash. However, for
less experienced officers, judging the
trim with eyes only is a difficult task.
We were therefore looking for ways
to dynamically measure and optimize
the trim. We even went as far as using
garden hoses to build level gauges that
helped us see when the trim was right.”
Testimony
”Having now used Eniram’s DTA for some time, we are clearly using less energy to achieve the same speed. The
benefit in percentage that we are talking about is a decrease of around five percent in fuel consumption, and this
is a conservative estimate.”

Solution
When its self-built solutions failed
to deliver the precision required by
the business, NCL found out about
Eniram’s Dynamic Trimming Assistant
(DTA). This advanced solution has
been purpose-developed to help
crews determine the optimum trim
of their ship during journeys. DTA
collects information on the prevailing
trim, propulsion power and vessel
movements. It then combines this with
information on current conditions such
as weather and speed to calculate and
display the optimum trim in realtime. NCL initially deployed DTA on
Norwegian Jewel, one of its premier
cruise liners, and crew members soon
discovered that the solution is very
easy to use.
Norwegian Jewel
DTA has a selfexplanatory user
interface and, when the indicator lies in
the green band on the DTA screen,
SUMMARY OF BENEFITS
crew members instantly know that the
trim is right. If the indicator is not in
the green band, captains can utilize
the up-to-date information presented
by DTA to make corrections to the
trim. “The system is very helpful,
especially at night when it is difficult to
get a visual of the vessel’s movement
through the water,” says Hansen. ”One
of the great parts of the DTA is that
there is almost nothing to learn and
very few buttons to press – quite the
opposite to many systems that have
complicated menus and commands
that need to be learned by heart.”
Benefits
Use of DTA on the Norwegian Jewel
enabled NCL to dramatically reduce its
fuel consumption and therefore reduce
its operating costs. “Having now used
Eniram’s DTA for some time, we are
clearly using less energy to achieve
the same speed,” says Hansen. “The
benefit in percentage that we are
talking about is a decrease of around
five percent in fuel consumption, and
this is a conservative estimate.”
The reduction in fuel doesn’t just
save money for the company. It also
helps NCL to take greater corporate
responsibility for reducing CO2
emissions.
•5% reduction in fuel
consumption
• Lower CO2 emissions
• Clear, real-time information
for crews onboard
• Improved understanding of vessel and fleet performance
“The savings have a direct effect on air
emissions, for which the cruise industry
will be more and more under scrutiny
in the coming years,” Hansen says.
NCL is so convinced of the benefits
of DTA that it has now rolled out the
solution to a further seven cruise ships.
Over time, it plans to make DTA a
standard piece of equipment in all of its
current and future luxury cruise liners.
Hansen concludes: “Eniram’s DTA
solution has proven to be a reliable and
beneficial system. It is a very useful
aid for officers and brings a measurable
reduction in fuel consumption. We plan
to keep using the DTA across our fleet,
and see further interesting possibilities
in utilizing the data collected for other
purposes as well.”
