Please note that the indicated delivery time only starts after receipt of the hull thickness in
the area of the tunnel. If the wall thickness of the tunnel has to be increased following

KIND OF INSTALLATION
The unit will be delivered in SCHOTTEL standard tunnel length. It will be welded into the
hull of the vessel with a vertical power input shaft arrangement. The thruster with its direct
connection to the vessel could be defined as a part of the vessels hull.
DESIGN & CONSTRUCTION
TRANSVERSE TUNNEL:
The transverse tunnel is a welded construction made of shipbuilding steel grade A
As protection against corrosion anodes are mounted on the tunnel wall and on the (2)
cover of the lower gearbox. The anodes are fixed to the thruster with small metal feet
leaving a gap between anode and tunnel for sufficient final coating by the shipyard. If there
is not enough space for the anodes, the not mountable anodes will be supplied loose and
have to be mounted by the shipyard after installation of the bow thruster. Anode protection
for the tunnel parts which are not scope of supply of SCHOTTEL is not delivered.
Aluminium anodes are required by the customer. (7)
Important Remark to be respected by the Shipyard
To ensure sufficient protection we recommend adding adequate anode protection fixed as
described above on the tunnel parts which are built by the shipyard. Furthermore sufficient

Rev 8
08.11.07 R. Schwandt VB4 TS-71108_3 Page 3/7
anodes have to be installed on the fore ship to protect the hull. If these anodes to protect
fore ship and tunnel are missing, then the anodes delivered with the tunnel thruster serve
as only protection for the complete fore ship. This means that these anodes will disappear
within only a few months and the thruster itself will serve as anode which can lead in short
time to severe damage of the transverse thruster unit. In regular inspections, the anode
mass should be examined and replaced when necessary.
Taking account to the anode mass supplied by SCHOTTEL a specialist for anode
protection should determine how much anode mass has to be added to achieve the
desired years of protection (at least two years).
In the section of the propeller a stainless steel ring is welded into the tunnel against wear
of the tunnel.
The tunnel is equipped with 2 outer stiffening rings and one central supporting ring. The
outer stiffening rings are flat on the bottom side which allows easy welding to the frame
structure and reduces deformations. In addition, the foundation of the electric motor is
stabilized by the supporting rings.
BOW THRUSTER GEAR UNIT:
The housing of the lower gearbox is manufactured using high quality cast iron GGG 40
and contains the bevel gear transmission.
The propeller shaft is made of steel with high tensile strength and is seated in roller
bearings. Shaft sealing is achieved through radial shaft sealing rings. High grade special
stainless steel rings are used for rings which are in contact with seawater.
The HPG precision bevel gears are made from high quality steel, case-hardened and re-
cut after hardening. This results in a highly accurate tooth profile which ensures perfect
matching of the bevel gear set and a high safety factor against contact stress.
The support arm of the underwater gear housing to the tunnel is welded in. It is part of
SCHOTTEL scope of supply.
All running surfaces of shafts, flanges etc. are coated with wear and corrosion resistant
material.
Attached to the propeller shaft a fixed pitch propeller is mounted by hydraulic connection.

LUBRICATION:
Lubrication is ensured by oil bath lubrication. Cooling of the oil is achieved by heat
dissipation in the lower gearbox to the running water.
The separate oil header tank with level gauge is equipped with a sensor (24V DC) for the
alarm indication 'oil level to low'.
Note : This oil header tank has to be installed by the yard approx. 1 meter above the
loaded waterline.
Connections between oil header tank and lower thruster unit are not scope of SCHOTTEL
supply.
Counter connection on Schottel components are to be supplied by Schottel. (2)

PROPELLER BLADE LAYOUT:
(4)
As basis for our propeller layout the following data is necessary.
Please countercheck if the data is correct:
The data has to be issued to SCHOTTEL latest 3 weeks after order:
−angle of frame in bow thruster area: No.1 39,5 °
(8)
No.2 59,4 °
(8)
−angle of waterline in bow thruster area: No.1 60,2 °
(8)
−No.2 67,2 °
(8)
−distance between centreline of tunnel
and keel: 1800 mm
(recommendation: 1.5 x D of propeller)
−distance between centreline of tunnel
and waterline: 4200 mm
(recommendation: 1.5 x D of propeller)
−distance of propeller to middle of tunnel: XX mm
−Effective tunnel length at centre line of tunnel: No.1 7197 mm
−No.2 4636 mm
(6)
−inlet of tunnel conical, cone depth: XX mm

Protection grids on tunnel ends have to be installed if vessel is ice classed (yard supply) In
addition, the tunnel has to be below the ice belt of the vessel (the thruster unit itself has no
ice-class).
POWER TRANSMISSION
ELASTIC COUPLING:
An elastic coupling (SCHOTTEL supply) is fitted between the power input shaft of the
tunnel thruster and the electric prime mover (form of construction: V1, not SCHOTTEL
supply) which is mounted directly vertical on the thruster unit.
PRIME MOVER
ELECTRIC PRIME MOVER (NOT SCHOTTEL SUPPLY)
A frequency controlled asynchronous motor will be used as prime mover.
ELECTRONIC CONTROL SYSTEM
Not in SCHOTTEL scope of supply.
ALARM SYSTEM
The following alarm contacts of the mechanical system will be provided and can be
connected to the ship’s alarm system:
•Oil level too low
INTERFACES ELECTRIC SYSTEM
None
TOOLS
If special tools are required for standard service of the unit they are in our scope of supply.
SPARES
Spares will be supplied according to requirements of the classification society.

COATING AND PAINT STRUCTURE
The thruster tunnel will be sandblasted and coated with anticorrosive primer. The lower
gearbox will be sandblasted and coated with BELZONA 1321 (Ceramic S-metal), with
extremely high resistance against abrasion, cavitations and electrolytic corrosion:
Lower gearbox: sand blasting SA 2 1/2 DIN 55928
2 layers BELZONA 1321 (Ceramic S-metal) coating each
approx. 270 µm
Tunnel: sand blasting SA 2 1/2 DIN 55928
1 x 2K Epoxy-resin-primer approx. 40 μm
(final coating by shipyard as tunnel is welded
into the vessel and is therefore part of the hull)
QUALITY ASSURANCE
SCHOTTEL provides a quality assurance system in accordance with DIN ISO 9001
certified by GL, ABS, BV and DNV. The thruster system will be supplied with a
SCHOTTEL works certificate.
CLASSIFICATION
