Both of the ships were equipped with AIS and
radars. INGER MARIE was on 245° with 8 knots of
speed. RIG was on a north-westerly course of 341 with
speed over ground of 9 knots. The ships courses did
not change within 60 minutes before the collision
occurred. The visibility was good and ships were in
sight of each other with no significant change of
bearing. At about 0535 RIG was in similar situation
with other fishing vessel with RIG taking initiative to
alter course to starboard to avoid collision.
According to COLREG vessels were power-driven
vessels in a crossing situation. Therefore Rule 15
should have been followed. RIG was supposed to give
way to INGER MARIE and INGER MARIE was a
stand on vessel but obligated to take action to best
avoid collision. None of the vessels managed to
follow Rule 5 about proper lookout as skipper was
most probably occupied with sorting langoustines and
duty officer on RIG failed to notice INGER MARIE
approaching. RIG officer reacted properly initiating a
starboard turn but the action was taken way to late to
be effective to avoid collision. It was suspected that
officer of the watch did not keep proper lookout by all
means available. Setting of the radar were giving little
time to react if target appeared on the screen. No
targets were acquired in ARPA. Similar situation of
RIG being involved in the close quarters situation
with other fishing boat just 30 minutes before
suggested that improper lookout was taking
prolonged time. Collision was classified as very
serious as loss of life had been a result of it.
2.5 Atlantic Lady & Kraslava (1 November 2014)
Atlantic Lady is a 139 meters long refrigerated cargo
vessel. At the time of accident she was on her way
from St. Petersburg (Russia) towards fishing grounds
near Bear Islands (Norway). Kraslava (presently San
Carlos) is a 182 meters long chemical/product tanker.
She departed Tenerife (Spain) and was heading for St.
Petersburg (Russia) passing through The Sound with
“In the Sound” pilot onboard. At the time of accident
ships were operating in restricted visibility (about 100
m) with southerly gentle breeze, 0,5 m high waves
and NE current of 2 knots.
Collision happened at 13.19 UTC close to buoys 16
& 17 marking southern entrance/exit to Drogden
Channel (fig. 14). Kraslava was proceeding south with
“In The Sound” pilot on board. The arrangements to
disembark pilot were in progress and pilot boar was
alongside Kraslava adjusting speed to take pilot on
board. Atlantic Lady was approaching buoy 16 after
passing Drogden Lighthouse on her port side. Buoy
16 was a marker to turn to starboard to align with
direction of the Channel. Though visibility was
restricted only Kraslava was giving appropriate sound
signals prescribed by Rule 35 of COLREG for vessel
restricted in her draught, as that was AIS status
advised by the pilot. Pilot also was keeping Kraslava
closer to the center of the Channel to avoid shallow
waters located just aside of it. Going out of dredged
channel may have cause the risk of grounding the
vessel. Atlantic Lady also had a status of constrained
by her draught but was not giving any fog signals. She
was planning to pass buoy no. 16 and then initiate
turn to starboard to go along eastern part of the
Channel. Master of Atlantic Lady, on the grounds of
his experience, presumed that Kraslava would hold a
position on the westerly side of a channel and allow
Atlantic Lady to turn into easterly side of it.

Both ships were equipped in working AIS, had 2
radars working. Kraslava was equipped also in
ECDIS, Atlantic Lady had ECS. Vessels were
observing each other on their radars. When they
became visible by sight to each other they were less
than 100 meters away from each other. Kraslava took
no action to avoid collision as her crew realized that it
was too late. Atlantic Lady’s master ordered hard to
starboard but that was also too late.
Both vessels were operating on restricted visibility
with no sight of each other but only Kraslava was
giving appropriate fog signals. Both vessels were
having a status of ‘constrained by draught’. According
to COLREG regulations Rule 19 was to be applied,
therefore there was no stand-on and give-way vessel.
Both vessels were obligated to maneuver to avoid
collision. But it must be noticed that neither of the
bridge team recognized risk of collision until seconds
before it had happened. Conjunction of few factors
like restricted visibility, pilot boat alongside Kraslava,
north-easterly current, navigating in narrow channel
and Atlantic Lady making a big course alteration to
starboard resulted in this two ships colliding with
each other. “The factor instrumental in the collision
was thus that ATLANTIC LADY’s approach to the
Drogden Channel, in the absence of other better
alternatives, necessitated a large turning manoeuvre.
Due to the north-easterly current and the restricted
visibility, which delayed the start of the turn until
buoy no. 16 was abeam, turning manoeuvre brought
the ship into the center of the channel, where it
crossed ahead of KRASLAVA.” [6]
3 CONCLUSIONS
Case study show that occurrence of accidents in
restricted waters is highly dependent on proper use of
