Tugberk-Imamoglu, a vessel loaded with 4,199 metric tons of rolled steel and reinforcing bar, has been at the center of a maritime tragedy following its collision with another vessel, the 'Alsu', off the coast of Silivri. On September 5, the wreck of the Tugberk-Imamoglu was discovered in the depths of the Sea of Marmara, approximately 18 nautical miles from the shore, at a staggering depth of 720 meters. Turkish SAR teams, utilizing a Remotely Operated Vehicle (ROV), managed to image the shipwreck, revealing significant damage including a large hull breach. The search and rescue efforts are ongoing, as the fate of the crew members remains uncertain, prompting both concern and urgency among authorities and maritime experts alike.
The investigation into the collision leading to the Tugberk-Imamoglu's sinking has unveiled contradictory testimonies between the crew members of the Alsu and various nautical regulations. Captain Ahmet Erarslan and Second Officer Murat Evciman from the Alsu described a scenario where visibility was severely compromised, stating they failed to see the Tugberk-Imamoglu's navigation lights and could not track it via the AIS system. They claimed that after being instructed to alter course, the Tugberk-Imamoglu unexpectedly turned towards their vessel, giving rise to a collision that led to the quick disappearance of the Tugberk-Imamoglu from radar.
However, a preliminary report concerning the incident suggests a far deeper issue involving bridge discipline and situational awareness on both vessels. The findings point to a significant oversight, highlighting that the Tugberk-Imamoglu was operating with its AIS turned off at the time of the collision. This action not only violated standard maritime protocols for vessel visibility but also exacerbated the situation by leading to a delayed response from the Alsu's crew. Experts noted that adherence to watchkeeping standards and the presence of an additional lookout onboard could have made a crucial difference in preventing the disaster.
The aftermath of this calamity has highlighted the critical importance of maintaining bridge discipline and the need for stringent adherence to maritime safety protocols. As authorities continue to seek for answers regarding the fate of the crew and the events leading up to the collision, the Tugberk-Imamoglu's tragic sinking serves as a stark reminder of the perils faced at sea and the necessity for vigilance and precaution among maritime operators.
