newsflash Conveyor Belt Change-out – Indominco Mandiri C-26 12.8 km OLC
In February 2008, PLORIM Bontang Coal Terminal Alliances consist of PETROSEA-LAING O’ROUKE-INDOMINCO tendering the C-26 overland conveyor belt change-out.
The conveyor change-out is part of Indominco Bontang Coal terminal up grading project.
The C-26 overland conveyor has a vertical lift of 7.3mtr is running at 6.2 m/s has a total c to c distance of approx 6.3Km, total tape length of belt is approx 12.8Km. The existing belt spec is ST-1120 1200mm wide. The new belt is 1250mm wide ST-1400 will be running at 7.2 m/s carrying 3,700 t/h.
Supra proposal is selected to by the Alliances to perform this critical job. The job required shortest shutdown time because the C-26 conveyor is a production conveyor. The only way to achieve this objective is to have all the belts pre-splice, lay-up in form of belt stack, join with old belt and pull in a one continuous length at a time.
The change-out work was a great success. We were given 150 hours for change-out, the work was completed in 87 hours, saving 33 hours for the mines that they can start loading to the coal 1 day earlier.
