A lifting accident last Thursday (14th April) with one of the world’s largest semi-submersible cranes caused tense moments in Norway as onlookers feared the vessel might be sinking. It involved a couple of cargo barges as well, causing some to capsize.

What Has Happened?

Saipem 7000 left the Seagreen offshore wind project in Scotland, where the vessel is installing the wind farm’s jacket foundations and scheduled for maintenance. It was expected to return to Scotland later this month.

According to Saipem, after having completed DP trials as per the DNV testing programme, Saipem 7000 was performing a planned five-year main cranes load test, under the attendance of the Classification Authority.

The vessel was in a Norwegian fjord in Åmøyfjorden, a centre for Norway’s offshore oil industry near the Port of Stavanger when the accident occurred. It has been unclear what the vessel was lifting when bystanders reported hearing a loud noise and thought that the vessel is going to sink.

Luckily, no one was injured in the incident and the crane vessel was righted afterwards. The authorities reported that the accident was due to the failure of one of the cables on the lifting crane. The load was lost, hitting the deck and a barge positioned alongside the crane, causing the barge to capsize but remain afloat.

Saipem preliminary assessment

In a statement released by Saipem, it has appeared that the main block wire broke during the test lifting operation and the testing load, the two cargo barges, with the main block, were released into the water.
