Sarens lifts column at refinery in Algeria
Crew uses CC2400 and CC9800 to replace 188-tonne column.
Date 09 January 2019
In 2010, Algerian national oil company Sonatrach began a refinery rehabilitation project in Sidi-Arcine, east of their Algiers refinery. This US$408 million project promises to increase refining capacity from 2.7 to 3.6 million tonnes per year, and includes the modernisation of a crude distillation unit, aromatic facilities, and catalytic reformer unit as well as associated auxiliary units. It also involves the construction of isomerate, para-xylene, and benzene units.
Sarens was commissioned to lift the refinery’s main column (530-C-021) in September, while the project was contracted to Technip SA. Sonatrach later appointed China Petroleum Jilin Chemical Engineering and Construction (JCC) to undertake construction work and replace the original column, with Technip’s assistance.
To execute the move, Sarens selected the following equipment:
- CC2400 in SL170T @ 30m configuration
- CC9800 in SSL 84m configuration
Sarens already had the CC2400 in Algeria. The CC9800, meanwhile, was shipped from Belgium to Algiers by boat and was rigged within 11-12 days.
The Sarens crew slewed to lift out the old column, weighing 188 tonnes and measuring 44 x 34 metres, and replaced it with the new column. Two crane operators and one lifting supervisor were involved in the operation, which took a total of three months to mobilise, execute, and demobilise.
