The youngest TLC subsidiary in Africa, TLC Ivory Coast, already has heavy-weight experience in terms of float on operations. Between the 11th and 20th March 2018, power barge Ayşegül Sultan as well as offshore support vessel Pacific Warrior were successfully loaded on OHT’s giant semi-sub heavy lift vessel, Osprey.
The operation took place in 2 steps. The power ship was first gently moved across the vessel submerged deck into position against the guidepost by the vessel’s own winches, while stand-by tugs were connected to the power ship for an instant pull-out as a contingency measure. On the next day, the loading of the supply vessel was performed.
As OHT’s agent for m/v Osprey, TLC Ivory Coast was in charge of the entry, position and sailing of the Osprey and took all measures related to the air draft of the vessel and cargo, and ensured safe passage under the high tension power cables in the channel. TLC Ivory Coast also provided a team of certified welders that would ensure proper sea fastening on m/v Osprey for the voyage to Yalova, Turkey. Finally TLC Ivory Coast assisted 3 on-signers & 5 off-signers, including the Loading Master.
Why choosing the port of Abidjan
The power barge was being used in Tema, Ghana. The choice of the port of Abidjan for the float on was then obvious not only because of the vicinity but also because of the port situation, actually located on a lagoon, only accessible by a buoyed channel (2.8 km). The particularly calm waters makes it an ideal location for large-scale float on/float off operations.
