Ok
the incident occurred in the traffic
separation scheme in the Straits of
Dover in the northeast direction lane of
the scheme off Cape green a the incident
occurred during the day in dense fog and
moderate seas bulk carrier he was
proceeding at 40 knots on heading of 0
20 degrees while another vessel see was
proceeding at 16 knots on a heading of
039 degrees and slowly gaining on vessel
e
tank barge I was proceeding on a heading
of 240 degrees at a speed of 11 knots
and was proceeding in the wrong lane of
the separation scheme another
unidentified vessel was also heading
northeast slightly west of ships e and c
at a time of 10 minutes before collision
c minus ten ships e has just passed
along the stern of e and both vessels
have become aware of ship only coming
towards them in the wrong lane
at a time of 6 minutes before collision
c minus 6 share i changed the course to
starboard into small alterations and
became on a collision course with ship e
consequently ship reacted to this change
by also turning to starboard
at a time of 4 minutes before collision
c minus four ships II was still
maintaining its original study course
and speed
ship e being aware of ship see reduced
it startled term to go back on its
original course
the south west bound barge i also
started to turn slowly to port in order
to come back on its original course and
pass between ship II and the
unidentified vessel
time two minutes before collision c- to
ship see gave the order
hard to starboard and being now aware of
imminent danger ship e gave the order
hard to port and ships c and e collided
into the side of each other
a few seconds later the stone of see
once again struck the starboard side of
ship e both vessel sustained damage but
could continue on their own power
in your opinion which vessel violated
which rule click on the buttons for a
quick overview of the relevant rules for
all six se rules 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 and be stopped within
a distance appropriate to the prevailing
circumstances and conditions rule 10

extract from rule 7 risk of collision a
every vessel should use all available
means appropriate to the prevailing
circumstances and conditions to
determine if risk of collision exists if
there is any doubt such risk shall be
deemed to exist be proper you shall be
made of radar equipment if fitted and
operational including long-range
scanning to obtain early warning of risk
of collision and radar plotting or
equivalent systematic observation of
detecting objects
extract from rule 8 action to avoid
collision be any alteration of course
and or speed to avoid collision shall if
the circumstances of the case admit be
large enough to be readily apparent to
another vessel observing visually or by
radar a succession of small alterations
of course and all speed should be
avoided
d action taken to avoid collision with
another vessel shall be such as to
result in passing at a safe distance the
effectiveness of this action shall be
checked until the other vessel is
finally passed and clear
extract from 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
name but when joining are leaving from
either side shall do so at a small an
angle to the general direction of
traffic flow as practicable
vessel I was proceeding in the wrong
direction in a traffic separation lane
without any good reason this initial
fault was compounded by the fact that
she was proceeding to fast that one
action was taken by altering course to
starboard these alterations of course
consisted of two very small alterations
of five degrees each and a further
alteration of 20 degrees
that action was a clear breach of rule 8
b of the collision regulations
both vessels C&E were proceeding much
too fast when approaching the Dover
straight in dense fog by the vessel
reduced speed when the presence of I was
detected and was clearly a potential
danger and after ship eater to starboard
onto a collision course the radar lock
out on both vessels were not
sufficiently effective so that early
avoiding action was not taken by either
vessel
ships II should have kept well clear of
ship e failure to do so was matched by
the failure of ship d to her proper
regard for the presence of ship see and
both vessels should be treated as
equally liable
