Overview

ALE has started the first phase of heavylifting scope for the Korchagin oil field development project in Russia.

ALE was contracted to perform the engineering, weighing, jacking, load-out and offshore pulling of the satellite platform (SP) topside for the project in Astrakhan.

The first stage of the project has started in November 2017 and involved jacking of the topside to 1.5m, and weighing of the 2,570t topside so the client can integrate skid beams in between the topside and the desk-support frame (DSF) underneath.

Lernik Mirzakhanyan, Sales Executive for ALE Russia, said: “Considering the sheer size of the desk-support frame on-site, we have completed a complex engineering design to account for the limited space available to perform the operation. As we cannot use forklifts or cranes to rig the equipment, we have utilised manual tools.

For project efficiency, the weighing was carried out by measuring the hydraulic pressures and flow rates rather than weightors.”

The next phase will involve the load-out of the topside with the DSF, weighing approximately 3,100t, to the transport barge, which is expected to start in December 2017.
