February 4, 2025, following scheduled preventive repairs at the CPC Marine Terminal, crude oil loading via SPM-1 (single-point mooring) resumed.
Opening a shut-off valve of the subsea pipeline end manifold marked the single-point mooring repairs completed on January 30, 2025.
The tanker moored for loading took part in receiving post-hydrotest flush water from SPM-1 cargo piping before oil-in.
Replacement of 40 hoses (26 subsea and 14 floating) took place during SPM-1 activities. The activities carried out required much labor with each hose section weighing from 2.5 to 5.3 tons. Meanwhile the single-point mooring itself is 5 km offshore.
These hoses take oil from SPM to the tanker via the system of two flexible floating strings of hoses.
Including marine breakaway coupling (MBC), butterfly valve and a cam-lock, the total length of the inner floating string of hoses is 265 m, that of the outer string is 276 m. The outer string consists of 26 hoses, the inner one - of 25.
The said activities are routine for high equipment reliability, environment and safety purposes.
Presently, all three SPMs of the CPC Marine Terminal operate normally.
