both in-line and vee layouts, maxi-
mum power rating currently
offered by the design is 3,200 bhp.
The Daventry plant continues to
make a key contribution to the
development of Cummins'
Quantum system of compact
machinery for the marine as well
as industrial and stationary power
markets. This is expressed in two
prospective additions to the range,
the QSK45 and QSK60 types,
which are due to be introduced in
1998. While the existing K38/K50
models span the 800 to 1,800-bhp
band, the new designs will cater to
applications between 1,200 and
2,600-bhp unit output.
Sulzer population
The assimilation of New Sulzer
Diesel into Wartsila NSD has
added a two-stroke dimension to
the Finnish-owned group, bring-
ing with it an approximate 35 per-
cent share of the newbuilding,
low-speed propulsion market and
the long-term business scope sig-
nified by the near 2,000 RTA
engines ordered to date.
Since its introduction in 1981,
the RTA series has been continual-
ly updated to meet market needs
and to reflect advances in technol-
ogy.
The current installation of
super wide-bore, 960-mm RTA96C
diesels in post-Panamax contain-
erships and the recent introduc-
tion of more compact versions of
the RTA-U series for tankers,
bulkers, boxships and other ves-
sels testifies to the market-led
product development policy. This
year's surge of orders for the
RTA84T type, unveiled in 1991 as
an optimized unit for VLCCs,
again vindicates the forward-look-
ing design approach.
By the end of April 1997, refer-
ences for the RTA range, encom-
passing 10 bore sizes from 380 to
960 mm, and a power spectrum
from 2,000 to nearly 90,000 bhp,
had passed 39 million bhp.
Marine propulsion installations
reportedly account for more than
38 million bhp.
Booked for eight post-Panamax
linehaul newbuildings to date, and
conceived for vessels as large as
the 8,000-TEU designs now under
discussion, the Sulzer RTA96C
accommodates speeds of up to 24
to 25 knots at the top end of the
capacity band, through an output
of 7,470 bhp per cylinder. It incor-
porates service experience with
the RTA84C, the market leader in
the large boxship sector with ref-
September, 1997
erences totaling 8 million bhp.
An enhancement to the range
this year has been the introduction
of shorter, lighter versions of the
RTA2U series, aimed at reducing
non-earning space in a ship's hull
and cutting engine manufacturing
costs as well as easing installation
at the shipbuilding stage. The
long-legged U-types offer a stroke-
to-bore ratio of about 3.5, exceeded
in the Sulzer stable only by the 4.0
of the T models.
While Wartsila's preeminent
market position in the medium-
speed category and the acknowl-
edged need to rationalize combined
resources has major implications
for the Sulzer four-stroke family,
new business has boosted the sales
tally for the Swiss-developed
ZA40S to 4 million bhp.
