The full scope of buoyancy tank (BT) replacement at the Single Point Mooring - SPM-2 was completed on 29 November 2022. Hydrotesting procedure was successfully completed, and the SPM is ready for tanker loading.
It is to be reminded that, like it was done for SPM-1, all engineering calculations, manufacturing, installation of auxiliary and main equipment, high-tech operations of dismantling, mounting and positioning the buoyancy tank at depth were performed by Russian specialists from CPC and Contractor, Alliance LLC.
We would like to note the teamwork of the Contractor and the crew of the Commander multipurpose vessel equipped with dynamic positioning systems, specialized diving equipment (MKVK-60) and a 140-ton crane. The 80-strong team worked in two shifts on board the Commander vessel. All the work was performed in strict compliance with occupational safety, industrial and environmental safety requirements and CPC’s 12 Life Saving Rules.
The pace of work was affected by bad weather conditions and frequently changing undercurrents typical of this period. Russian Specialists performed dynamic risk assessments on a daily basis to take into consideration the evolving situation. A particular complexity in the work arrangement was that the operation required about two days of ongoing process and had weather-related restrictions - a wave height of no more than 1.5 meters and wind speed no more than 20 meters/sec in autumn/winter conditions.
