Ok
the incident happened in the Arak Oh
straight which connects the port of
nagoya in Japan to the open sea
the straight has a buoyed channel with
two light boys marking its center line
positioned on the heading of 133 degrees
the incident happened at night when
there was good visibility and moderate
weather
at a time of 13 minutes before can
didn't c minus 13 ship em crossed the
center line of the channel into the
opposite lane
at a time of 11 minutes before collision
c minus 11 ship em were still steady on
the course of 123 degrees and positioned
clearly in the opposite lane
at a time of 6 minutes before collision
c minus 6 ship them sees the red side
light of ship ji at a bearing of 6 27
degrees on her starboard bow and ship ji
is in a position to see the green side
light of ship em at a bearing of 5 to 6
degrees on her port bow
as a time of two minutes before
collision c- to ship ji sounded five
short blasts and flash the oldest light
of the other ship both ships kept their
course and speeds
hmm
at a time of 1.5 minutes before
collision c minus 1.5 shivji sounded one
short blasts put the rudder hard to
starboard and ordered half a head speed
while ship em sounded too short blasts
and put the rudder
hard to port
hmm
at a time of one minute before collision
c minus one ship ji ordered
full speed ahead while ship em were
still turning to port a time of
collision ship ji is turning starboard
with a speed of between 15 to 17 knots
when ship em ordered
full speed astern the bow of ship ji
struck ship em on the starboard side in
the vicinity of cargo hold number one
and at an angle of about 45 degrees ship
em sustained considerable damage but
both ships remained afloat and there was
no loss of life

extract from rule 6 safe speed every
vessel shall at all times proceed at a
safe speed so that she can take proper
and effective action to avoid collision
will be stopped within a distance
appropriate to the prevailing
circumstances and conditions
extract from rule 8 Action too
collision a any action to avoid
collision shall be taken in accordance
with the rules of this part and if the
circumstances of the case admit b+ made
an ample time and with due regard to the
observance of good seamanship
extract from rule mine narrow channels
the vessel proceeding along the course
of a narrow channel or fairway shall
keep as near to the outer limit of the
channel of fairway which lies on her
starboard side as is safe and practical
ball
extract rule 10 traffic separation
schemes
a vessel using a traffic separation
scheme shall one proceed in the
appropriate traffic lane in the general
direction of traffic flow for that Lane
two so far as practicable keep clear of
traffic separation line or separation
zone and three normally join or leave a
traffic lane at the termination of the
lane but when joining or leaving from
either side shall do so at a small an
angle to the general direction of
traffic flow as practicable
extract from rule 14 head-on situation
when to power-driven vessels are meeting
on reciprocal orly reciprocal courses so
as to involve risk of collision each
shelter her course to starboard
so that each pulse on the port side of
the other
extract from rule 15 crossing situation
when to power-driven vessels are
crossing so as to involve risk of
collision the vessel which has the other
on her starboard side shall keep out of
the way and shall of the circumstances
of the case admit avoid crossing ahead
of the other vessel
extract from ruled 17 action by stand on
vessel where one of two vessels is to
keep out of the way the others will keep
her course and speed
the latter vessel may however take
action to avoid collision by her
maneuver alone as soon as it becomes
apparent to her that the vessel required
to keep out of the way is not taking
appropriate action in compliance with
these rules when from any cause the
vessel required to keep her course and
speed finds herself so close that
collision cannot be avoided by the
action of the gift way vessel alone she
shall take such action as well best
eight to avoid collision
ship em was steering a course of about
10 degrees to port of a direct course
along the channel and therefore she was
a ship proceeding along the channel in
the opposite direction to that of ship
ji rather than a ship crossing the
channel or straight and therefore the
crossing rule under the collision
regulations did not apply
similarly there was no stand on vessel
with an obligation to keep her course
and speed until the two ships were so
close to each other that a collision
could not be avoided by the action of
one vessel alone on the contrary both
ships were free to alter either their
course or speed and keep to the
starboard side of the fairway in
accordance with rule mine and the
principles of good seamanship at any
time in order to avoid collision
additionally the principal aspects
related to establishing what is
considered a safe speed were not
observed em was at fault in four main
respects
hey setting a course of 123 degrees
which took her over to her wrong side of
the channel be leaving it's much too
late to take avoiding action to avoid a
collision see keeping a poor look out
when approaching each other
shivji was observed showing her masthead
lights a little open to starboard and
her red sidelight clearly visible
d finally when finally taking action to
avoid a collision putting the wheel hard
to port instead of hard to starboard all
these faults were fundamental to the
cause of the collision ship ji was at
fault for not reducing speed by stopping
her engines or at least reducing speed
too slow ahead
not later than when the ships were about
two miles apart
