the ferry service between Den Helder
and Texel. One of the initiators of the
service was Dokter Wagemaker, a local
physician. TESO expanded rapidly in
order to meet the passenger demand, and
after his death, one of the vessels was
named after Dokter Wagemaker in May
1934.
The new Dokter Wagemaker is a high-
ly sophisticated vessel being a hybrid
between a ferry and a luxury cruise liner.
Dokter Wagemaker will replace
Molengat, which will be sold. Dokter
Wagemaker is the result of the fleet
renewal and capacity increase program
which was initiated by TESO.
Damen Shipyards Gorinchem was
awarded the contract in April 2003.
Schelde Naval Shipbuilding, a member
of the Damen Shipyards Group, execut-
ed the contract and carried out the basic
and detailed engineering, subcontracting
hull construction, outfitting, testing and
delivery of the vessel. Hull construction
and pre outfitting took place at Damen
Shipyards Galati in Romania.
The new RoRo Passenger Ferry is
classed by Lloyd's Register as + 100 A1

The vessel is fitted with a highly auto-
mated Diesel Electric propulsion system
comprised out of four generating sets
divided over the forward and aft engine
rooms. The sets develop 2,856 kW @
1,000 rpm each. The generating sets are
resiliently mounted on base frames.
Power is generated at 6 kV and trans-
formed to 400 and 230V at 50Hz.
Thruster units are installed in the
propulsion rooms with prime movers
and associated equipment.

Rigdon Marine took delivery of the
first batch of new generation 210-ft. (64-
m) diesel-electric off shore supply ves-
sels. In Norway, the building of a series
of 92-m boats followed the success of
the U.S. vessels with similar Cummins
diesel-electric propulsion packages.
Currently, in a cooperative effort involv-
ing American, European and Chinese
firms, a series of ten 240-foot (73.2-m)
vessels are being built in China for the
France-based SURF, a member of the
maritime branch of Groupe Bourbon.
The first of the series was undergoing
sea trials at Zhejiang Shipbuilding at
Ningbo Southeast of Shanghai in mid-
June. Vessels number 2, 3 and 4 were
alongside being fitted out while vessel
number 5 was taking shape nearby.
While significantly longer than the
American-owned diesel-electric boats,
the Chinese boats have retained the
same 50-ft. (16.5-m) beam. To allow for
the larger vessel size and increased
cargo capacities the total horsepower
has also been increased. While the U.S.
vessels have two Cummins-D(M)
Marine Generators and one Cummins
KTA38-D (M) powered 900 kW genera-
tor, the Chinese-built vessels employ
three of the QSK-60 powered genera-
tors. (The Norwegian vessel has four of
the units). The 16-cylinder four-stroke
engines each develop 2,548 bhp (1,901
kW) at 1,800 rpm which in turn pro-
duces 1,825 kWe at 60 Hz . The genera-
