Ok
the incident happened in the Gulf of
Mexico in an area south of Louisiana and
the southwest see boy this is a
non-compulsory fairway which extends
from the boy to the Gulf in a cell for
direction passing between offshore
platforms in that area
the incident occurred at night in good
visibility and ordered whether two ships
a bulk carrier e and a tanker j.r
outward-bound both proceeding at full C
speed on a heading of 180 degrees
additionally a lash carrier a was inward
bound proceeding at full C speed and
heading on a course of 326 degrees
proceeding toward the southwest see boy
at a time of 12 minutes before collision
c minus 12 ship a observed the red side
lights and mast headlights of the two
outward-bound vessels and ship observed
the green side lights and mast
headlights of ship a on a bearing of 40
degrees in her portside the vessels were
in a crossing situation
meanwhile ship Jay has overtaken ship e
on her own starboard side both keeping
parallel headings of 180 degrees
ship a calls the two southbound
vessels under the hf on channel 16 but
received no response
the pilot station provides ship a with
the names of the two vessels and ship a
calls them again but with no response at
a time of 3 minutes before collision c
minus three ship e altered her course by
10 degrees to starboard and gives a
short blasts on the whistle
at a time of two minutes before
collision c- to ship a reduces her speed
to dead slow ahead and give short blasts
on the wisdom
hmm
at a time of one minute before collision
c minus one ship e sounds one short
blasts and orders
hard to starboard on the helm
mmm
at the same moment ship a turns hard to
port and orders
full astern on the engines
the bow of shipped a strikes ship beyond
her port side at an angle of about 90
degrees and both vessel sustained
damages but there is no loss of life

extract from rule 7 risk of collision
every vessel shall 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

collision pay any action to avoid
collision shall be taken in accordance

circumstances of the case admit b+ made
in ample time and with due regard to the
observance of good seamanship
roll 10 traffic separation schemes a
this rule applies to traffic separation
schemes adopted by the organization that
does not relieve any vessel of her
obligation and any other rule
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 show if the circumstances of
the case admit avoid crossing ahead of
the other vessel
extract for rule 16 action by give way
vessel every vessel which is directed to
keep out of the way of another vessel
shall so far as possible take early and
substantial action to keep well clear
extract from rule 17 action by stand on
vessel where one of two vessels is to
keep out of the way the other shall keep
her course and speed type your answer in

ship-days failure to keep clear of ship
be by altering course to starboard in a
crossing situation violated the
collision regulation rules eight and
fifteen and was so cause of collision
the two mile wide safety fairway in the
Gulf of Mexico's international waters
running between offshore structures 46
miles south of Southwest past see boy
does not constitute a narrow channel nor
two vessels using this voluntary
shipping lane require any special rights
ship Jay did not impede the navigation
of overtaken ship e+ contribute to the
latter's being rammed by ship a who
violated several applicable rules of the
international regulations visual contact
on a clear night was a more than
adequate form of communication and
shipped JJ did not violate the bridge to
bridge communication act by failing to
use a radio to alert oncoming a which
was the giveaway vessel in a crossing
situation
