Wärtsilä, the marine industry's leading ship power system integrator, has signed
a contract with the German shipowner Jüngerhans, located in Haren (Ems),
Germany, to refit two of its vessels with Wärtsilä Slow Steaming Upgrade Kits to
cut fuel costs. The 1997-built vessels are equipped with 7-cylinder Wärtsilä
RTA62U main engines.
"The Wärtsilä Slow Steaming Upgrade Kits will give these ships considerable
flexibility for adapting to the prevailing challenging market conditions. They
offer considerable cost savings when slow steaming the ships, while retaining
the capability for full speed whenever necessary," comments Mr Herm Jüngerhans,
Managing Director, Jüngerhans.
In response to over-capacity in the market and a desire to cut overall fuel
consumption, during recent months charterers have adjusted both their services
and the speed of their ships. Slow steaming has become an established way of
operating vessels, particularly in the container segment. Slow steaming offers
clear benefits for charterers in terms of substantially reduced fuel consumption
and considerable savings in overall ship operation costs.
Wärtsilä Slow Steaming Upgrade Kit
For ships powered by Wärtsilä RTA and RT-flex low-speed engines with more than
one turbocharger, Wärtsilä introduced its Slow Steaming Upgrade Kit in 2008. The
kit enables ship owners and operators to achieve major savings in fuel costs by
allowing them to slow steam their ships.
"The Slow Steaming Upgrade Kit both extends the load range of the engine for
continuous operation, and significantly reduces BSFC (brake specific fuel
consumption) in the low-load range," explains Jürgen Gerdes, Director, Services,
Wärtsilä in Switzerland.
The Wärtsilä Upgrade Kit Slow Steaming also helps ship owners, operators and
charterers to increase the flexibility of their engines, permitting them to run
anywhere from 10% to 100% maximum load without operational restrictions, and to
decrease the risk of engine fouling and excessive component temperatures. The
BSFC figures that can be achieved are strongly dependent on the final NOX
emission balances over the entire load range. For ships that must comply with
the IMO NOX emission regulations, the restrictions imposed by the emissions
limits will be evaluated in each case and a customized solution package offered.
"Operational flexibility was a major factor in our decision to choose Wärtsilä's
solution. We foresee that the upgrade kit will give our vessels even more
competitive advantages. We wanted to have a reliable slow steaming solution in
order to be attractive in the market and this gives us an advantage over other
charterers," adds Mr Herm Jüngerhans.
Other orders and first operating results
With the order from Jüngerhans, the total amount of ordered upgrade kits has
increased to twelve, and Wärtsilä is already able to assess the initial
operating results for its Slow Steaming Upgrade Kit. For an 8-cylinder Wärtsilä
RTA62U engine, it was possible to achieve fuel savings of up to 6-10 g/kWh in
the optimal load range. On a 12-cylinder Wärtsilä RT-flex96C engine equipped
with three turbochargers, the measured fuel savings of 8-12 g/kWh were slightly
higher because the achievable savings are related to the number of
turbochargers. Since installation, the vessels have been running successfully
and the customers have had the flexibility of choosing whether to slow steam or
not.

Reederei Jüngerhans in brief:
As early as the 19th century, the grandfather of the two brothers Captain
Heinrich and Captain Hermann Jüngerhans crossed the Atlantic on the sailing ship
"HELENE" heading for South America. The ship, with a length of 24 metres and a
load capacity of 220 tons, was built in 1890 in Haren (Ems) for "deep sea"
trading.
Seventy years later, the grandchildren Captain Heinrich and Captain Hermann
Jüngerhans carried on the family tradition as independent ship owners, launching
their first own ship, the MV "STEFAN J", in 1965.
During the following decades, the shipping company developed continuously and
with an orientation to the future. Numerous ships were ordered from selected
shipyards around the world.
Today, the Shipping company Jüngerhans has launched about 100 vessels.
Due to the constant acquisition of new ships and the sale of older vessels, the
company now has a very young and modern fleet. The expansion of the fleet has
always been accomplished with a view toward the future. Moreover, the group has
expanded through cooperations and investments, therefore securing its market
position and opening up new areas of activity.
