Important Notice
■ Purpose and Application of Use
・ The ARG suppresses a rolling motion of the ship.
・ The ARG applies a principle that the Gyro torque (force) is generated by
inclination of the flywheel rotation at high speed.
■ General Information
・ In order to safely install and operate the ARG
(a) Only the repairmen, who have received the specified training about the
ARG , are permitted to perform the test run and inspection other than
items mentioned in this manual.
(b) Before installation of the ARG , carefully read this manual of the ARG
for comprehending the details. If starting the work with insufficient
knowledge, it may cause the ARG failure or an accident resulting in
injury or death.
(c) Do not disassemble and modify the ARG by yourself.
If the ARG is disassembled or modified by the user,
－ It may cause a decrease in the ARG performance.
－ It may endanger human life.
－ It may cause a health problem.
－ It may cause damage to the ARG or ship.
・ Depending on the type of the ship, it may be necessary for you to use multiple
ARG s. In this case, the methods of installation and electric wires are somewhat
different from those described in this manual.
・ Please observe the applicable governmental and local laws and regulations.
・ Please observe the governmental and local regulations for exportation of the ARG .
・ Please observe the governmental and local regulations for disposal of the ARG .

■ Important Information for Installation and Operation Safety
・ The most important purpose of safety measures is to prevent the persons from
an accident resulting in injury or death as well as to protect the ARG and ship
from avoidable trouble.
・ For preventing injury/death in an accident and the ARG from damage, follow
the cautions, rules, and instructions described in this manual and attached
operational instructions giving the top priority to safety. If ignored,
(a) It may endanger human life.
(b) It may cause a health problem.
(c) It may cause damage to the ARG or ship.
・ Tohmei Industries co., Ltd. cannot foresee all possible danger existing in the
ARG , resulting from human error, and in the environment where the ARG is
used.

suppresses rolling motion of the ship.
・ The ARG applies a principle that the Gyro torque (force) is generated by
inclination of the flywheel rotating at high speed.
・ The ARG stops automatically in abnormal conditions (excessive load,
abnormal temperature, etc.).
Others Start up duration to the rated speed: Approx. 30 minutes
To stop the operation completely from the steady state: Approx. 60 minutes.
* 1) Power consumption varies with the customer generator.
* 2) Measurement as per TOHMEI’s specification.
The measurements data depend on measurements conditions (installation place,
measurements method, etc.).

3 Before installation
3.1 ARG Gyro torques (moment)
In order to suppress the rolling of a ship due to waves or other external forces, every
ARG exerts a maximum torque of 9.8kN ･ m/1EA(approximately 1,000kgf ･ m /87,000lbs ･
in/1EA)on the hull of the ship, as shown in Figure 3-1.
Figure 3-1 Gyro-generated torques (moments)
If the maximum torque (moment) shown in the above diagram is generated, each of
installation bolts of the ARG must bear the loads of the magnitudes as shown below.
Tensile/compressive load on each bolt ········ 7.7kN (786kgf/1,700lbs)
Shearing load on each bolt ······················· 2.7kN (280kgf/620lbs)

3.2 Installation location and reinforcements for installation
(1) Installation location and reinforcements for the ARG unit.
DANGER
Do not disassemble or
modify
without
authorization, and do not use the ARG for other
purposes.
Doing so could result in damage, malfunction, injury or
electric shock.
Choose the location for installing the ARG unit
appropriately in consideration for ship’s center of
gravity, balance, and reinforcement besides
convenience.
Not doing so could result in deterioration in the
performance of ship.
Ventilate
the work space
if
the work
related
to
the
ARG is in closed space.
Not doing so could result in poisoning depending on the
materials to be used.
Do not install the ARG unit in the following
locations.
Doing so could result in electric shock, malfunction,
damage to ship or fire.
・
Locations exposed to wave, rain, wind or
direct sunlight.
・ Locations exposed to harmful gases, dust, liquid
or oil mist.
・ Locations without flat surface.
・ Locations where strength and stiffness of the hull is
not enough to withstand the maximum gyro torque
(moment), and a member from which the load can
not be transferred to the major members of the hull.
・ Locations exposed to vibration.
・ Locations where the specified ambient
temperature range.
・ Locations exposed to flammable materials or
heat-sensitive items.
・ Locations without a space of 200mm (7.9inches)
around the ARG unit. But if there are enough
space where the inspection and maintenance can
be performed, this space (200mm(7.9inches))
could be a target.
・ Locations where passengers can touch the ARG
unit easily.
① Install the ARG unit in a place withstanding the maximum gyro torque (moment)
described in section 3.1 in the hull. (For example, a place where the load is
transmitted to the strength material of the hull)
