1. Summary
1.1 At about 0805 on 16 September 2010, while the Hong Kong registered cargo ship
Strait Challenger was at anchor loading logs in Miri Anchorage, Sarawak, Malaysia,
the Ordinary Seaman (OS) “Yu” who was working on the lashings over the deck log
cargoes near the ship’s side fell overboard and disappeared into the water.
1.2 Despite search and rescue (SAR) operation conducted by the ship’s crew immediately,
and afterwards by the ship’s lifeboat and a fishing vessel nearby, and continued for
the next 7 days by a local marine police rescue boat and a Malaysia Coast Guard
rescue boat as well as a diver boat, the missing OS could not be found.

1.4 The investigation r evealed t he following contributing factors:
At the time of the accident, the weather was fine. The sky was clear and visibility
was good. The wind was southwesterly with force 3. The sea state was smooth but
the water was muddy with current setting northeast at a speed of about 1 knot.
• the OS was inexperienced in working deck log cargoes (he had less than 2
months service on log carrier) and he was not briefed by the experienced officers
or ratings of the risks, such as being liable to slip and fall, in working with deck
log cargoes before he was assigned the work.
• at the time of the accident, the guard lines or rails as well as the lifeline were not
erected yet and the OS was neither equipped with a fall protection system nor
wearing a life-jacket when working on the lashings over the deck log cargoes
near the ship’s side.
1.5 Safety factor:
• ship’s safety management manual did not state that crew members should be
protected by guard lines or rails and lifeline (or alternatively by lifeline and fall
protection system applied to them) in addition to protective clothing and
equipment, such as studded boots or studded overshoes and hard hats, when

All times are local (UTC+8)
The Accident
4.1 On 14 September 2010, the Hong Kong registered ship Strait Challenger arrived at
and anchored in Miri Anchorage, Sarawak, Malaysia, and commenced loading log
cargoes on the same day.
4.2 At about 0805 on 16 September 2010, the Ordinary Seaman (OS) “Yu” fell overboard
and disappeared into the water when he was working on the lashings over the deck
log cargoes near the ship’s port side at the after part of No. 1 Hatch, see Figure 3. At
that time, the Bosun, the Able-bodied Seaman (AB) “Zhang” and the OS “Dai” were
also nearby working on the lashings over the cargoes in No. 1 Hatch.

overboard (the photo was taken at sea after vessel departed from Miri Anchorage).
4.3 At the time of the incident, the weather was fine. The sky was clear and visibility
was good. The wind was southwesterly with force 3. The sea state was smooth
with current setting northeast at a speed of about 1 knot.

4.4 After OS “Yu” had fallen overboard, OS “Dai” immediately jumped into the water
attempting to search and rescue “Yu”. Shortly afterwards, the duty crew threw a
lifebuoy with rope into the water, and the duty officer, the Chief Officer and the
Master were informed of the accident. After about 5 minutes, OS “Dai” climbed
back to the ship. He could not locate the missing OS and reported that some blood
was observed in the water and the water was muddy.
4.5 At 0835, starboard lifeboat was lowered and launched into the water to search for the
missing OS. At 0852, a fishing boat nearby was requested to assist in the search and
rescue (SAR) operation. Meantime, the Master telephoned and informed the ship
management company of the accident. He also emailed and requested the company
and the ship’s local agent to arrange for and assist in the SAR operation.
4.6 At 0917, the Master sent a distress message to Rescue Co-ordination Centre (RCC)
via Land Earth Station (LES) Yamaguchi in Japan. At 0931, Japan Coast Guard
(JCG) acknowledged receipt of the distress message. The Master then sent an email
to JCG to request them to transfer the distress message to the RCC in the vicinity of
the vessel.
4.7 At 1020, 1140 and 1330, a local marine police rescue boat, a Malaysia Coast Guard
rescue boat and a diver boat arrived scene and assisted in the SAR operation
respectively. The SAR operation continued, but the missing OS could not be found.
At 1600, 18 September 2011, the vessel set sail for bunkering in Singapore and
discharging in Kandla, India.
4.8 SAR operation continued for the next 7 days, however, the missing OS could not be
located and the operation was finally terminated on 23 September 2010.

5. Analysis
All times are local (UTC+8)
Experience of the missing O rdinary S eaman
5.1 The missing OS was 38 years old. He started his seafaring career on 31 August
2009 and worked on a bulk carrier for about 7 months as his first ship. Strait
Challenger was his second ship, a bulk and log carrier. He joined the vessel on 9
July 2010. He had no experience in working log cargoes before. By the time of
the accident, he only had a total of about 9 months sea service and had less than 2
months shipboard experience on vessel carrying logs. He is considered
inexperienced in log cargo operation. However, the experienced officers and/or
ratings had not brief him of the risks, being liable to slip and fall, in working with
deck log cargoes before he was assigned the work.
Physical Condition of the missing O rdinary S eaman
5.2 The OS had taken a medical examination prior to joining the vessel. There was no
evidence that the OS had suffered from bad health. The other crew members were
not aware that the OS had any medicine/drug or alcohol consumption prior to work
on the day of the accident. The OS was a day worker and he had a continuous rest
period of slightly more than 12 hours prior to the accident. Fatigue is considered not
an issue in this accident.
Working on Deck Log C argoes – S afety E quipment
5.3 When loading in No. 1 Hatch was completed (loading in other Hatches continued),
the crew was tasked to tighten the lashings over the deck log cargoes in No. 1 Hatch.
However, the guard lines or rails and the lifeline (or alternatively, lifeline and fall
protection system applied to crew member) as recommended in the Code of Safe
Practice for Ships Carrying Timber Deck Cargoes, 1991, were not yet erected. The
missing OS was only wearing safety helmet, coveralls, gloves and studded overshoes
but was neither protected by a fall protection system nor wearing a life-jacket at the
time of the accident. Should he be equipped with a fall protection system, he would
be protected from falling overboard. Should he be wearing a life-jacket, he would
be protected from drowning and missing in case of fallen overboard.
5.4 In the ship’s safety management manual, it was not stated that when working deck log
cargoes, the crew members should be protected by guard lines or rails and lifeline (or
alternatively by lifeline and fall protection system applied to them) in addition to
protective clothing and equipment when working deck log cargoes.

Weather Conditions
5.5 At the time of the accident, the weather was fine. The sky was clear and visibility
was good. The wind was southwesterly with force 3. The sea state was smooth but
the water was muddy with current setting northeast at a speed of about 1 knot.
Weather conditions are considered not attributing to the accident.
Procedures for requesting as sistance from Rescue Co-ordination Centre
5.6 In using the equipment of the Global Maritime Distress Safety System (GMDSS) to
request assistance for this man-overboard situation, the Master sent a distress message
by the Immarsat system via the Land Earth Station (LES) Yamaguchi in Japan to
request the Japan Coast Guard to transfer the distress message to the Rescue
Co-ordination Centre (RCC) in the vicinity of the vessel. He should also preferably
send the distress/urgency message via VHF DSC, MF DSC and HF DSC which
would address all the stations including RCCs and ships, and would be acknowledged
directly and instantly by the RCC or ships nearby.

7. Recommendations
7.1 A copy of the report should be sent to the owner/management company and the
Master of Strait Challenger informing them of the findings in this accident.
7.2 The owner/management company of Strait Challenger is recommended to issue
notice/circular to draw the attention of their Masters, officers and crew members to
the findings in this report and ensure that
• crew members, particularly inexperienced ones, are to be briefed of the risks,
such as being liable to slip and fall, in working with deck log cargoes before
they are assigned the work;
• crew members are to be protected either by guard lines or rails as well as
lifeline (or, alternatively, by lifeline and fall protection system applied to them)
in addition to the protective clothing and equipment, such as studded boots or
studded overshoes and hard hats, when working deck log cargoes; and
• the above safety procedure and safety precautions are to be incorporated in the
ship’s safety management manual.
