Breaking moorings high on the list of STS incidents

Analysis of the increasing amount of data contained in the OnlineSTS.net OSIS database, which assesses ship-to-ship transfer (STS) operations, shows that the majority of the incidents reported are associated with breaking mooring lines.

Analysis of the increasing amount of data contained in the OnlineSTS.net OSIS database, which assesses ship-to-ship transfer (STS) operations, shows that the majority of the incidents reported are associated with breaking mooring lines.

Second in the list of incidents are vessel collisions, all of which took place while undergoing an STS operation at anchor, according to the database.

Participating third party vessels are assessed with respect to manoeuvring, mooring lines condition, mooring gear, crew performance and engine performance.

An interesting fact emerging is that about 5% of third party participating vessels have received a negative assessment with respect to crew performance. This is directly associated with experience coupled with crew training for such operations, the company said.

Although tanker STS operations form part of a vessel’s normal operational routine, crew training received the worst assessment among the other categories.

However, it would be interesting to investigate the crew performance in normal day-to-day ship operations and compare the findings, the company said.

As the database expands with more participants sharing information, problems such as these can be highlighted, the company said.
