OFFSHORE WORK IN THE JURI KORCHAGIN OIL FIELD IN RUSSIA.

OFFSHORE WORK IN THE JURI KORCHAGIN OIL FIELD IN RUSSIA.

The Juri Korchagin oil field is located in the northern part of the Caspian Sea. There, the Lukoil company wanted to build an ice-resistant drilling platform that would consist of two blocks: the production facility and the accommodations. In order to ram the foundation pipes with an outer diameter of 84 inches (2,134 millimetres) and a length of up to 71 metres, our client needed a powerful machine with a powerful crane and grab unit. Only with this was it possible to grab the pipes lying on their side and also hold them during the erection - because this process requires a high and stable tension.

For foundation pipes with a length of up to 71 metres, our client needed a powerful machine with a powerful crane and grab unit.
The pipes lying on their side could be gripped with our vibration unit and also held during erection without a drop of oil leaking out.
All pipes were safely threaded and driven into the seabed

After a detailed consultation, we came up with the ideal solution together with the customer: We rented him a MS-240 HHF vibrator unit in combination with an MS-A 1150 V power pack. On the construction site, the vibrator was placed on its side. Then the pipes were gripped on the side, set up and placed in a so-called conductor. This pile-driving guide prevents the pipes from slipping when they are positioned. Afterwards, they were first brought to a low pile-driving depth with a vibrator and then driven in with a hydraulic hammer. Several challenges had to be mastered at the same time: The lubricating oil was not allowed to leak from the inside of the vibrator, nor was a pipe allowed to sink into the sea as a result of a handling error or slip during insertion.

The work was completed on schedule to the great satisfaction of all involved. In a second construction phase, the further expansion of the drilling platform took place - our MS-240 HHF was also used here again.
