As a result of studying this section you will know what could cause an emergency
situation know what to do when an emergency situation occurs be able to
locate all emergency valves on the actuator
you
emergency steering is the same as local steering from the steering gear
compartment the operator has to push directly on the valves on the actuator
and keep his eyes on the rudder angle indicator wheel on the top of the
actuator rudder commands are to be received by phone from the bridge local
steering can also be done from the starter cabinets front panel
situations in which local steering may be necessary failure on the rudder or
rudder indication system bridge out of function
cable breakage
it is extremely important that the procedure for switching over to local
steering mode is familiar and drilled so everyone involved knows what to do this
is described in detail on the operating instructions I grabbed which hangs on
the bulkhead in the wheelhouse and in the steering gear compartment you should
study this operating instruction diagram on your vessel and go down to the
steering gear compartment to become familiar with the emergency steering
controls the controls may vary on different types of steering gear on the
following pages you will be shown the operating instructions I am click on the
hot spots to read the procedures changeover procedure start or stop of
pumps can be done from the bridge pumps are independent of each other pumps can
operate the steering gear independently or together each pump has its own
independent steering control circuit following valves have to be in open
position a b c d e and f electrical or valve block failure alarm one one pump
in operation 1.1.1 start standby pump if not also started one point one point to
stop the pump with failure function to two pumps in operation two point one
point one stop pump with failure function caution in some circumstances
the rudder may not respond to helm and no alarm is given if this happens
proceed as follows one point two point one change to non follow up steering
mode one point two point two start standby pump one point two point three
stop pump with function failure one point two point four control rudder
movement on the rudder indicator two point two point one switch over to non
follow up steering mode two point two point two stop pump number one control
the rudder indicator if none go to two point two point three two point two
point three start pump number one again and stop pump number two control the
rudder movement on the rudder indicator steering from the steering gear
compartment start and stop of pumps can be done in steering gear compartment
switch off B 1 and B 2 a by use of the non follow up switch in front of starter
or B by activating ll or mm depending on which pump in operation
open valve k valve e and f are normally open closed valve k after refilling the
steering gear has to be refilled through one steering gear pump by using the
storage tank system closed valves a and B or C and D
