Early October 2020, ALTRAD Nigeria (PREZICON Ltd) was awarded the full painting refurbishment for the hull of the BONGA FPSO. The 300-metre long FPSO (Floating Production Storage and Offloading), which belongs to Shell Nigeria Exploration & Production Company Ltd (SNEPCo), started production of oil in 2006 and is one of the largest of its kind in the world. Several methods of access have been deployed (rope access, V-deck, UHP robot) to blast and paint this hull since early November 2020.
Altrad Nigeria is already present on BONGA FPSO non stop since more than 12 months working on top side modules, water ballast tanks… This hull project is then a new challenge four our Nigerian team. Project is planned to last for 6 months.
With the help of ALTRAD UK, ALTRAD Nigeria performed its first online desanding of pressure vessels for Shell Nigeria. Three vessels were cleaned with zero impact on Shell production or environment. 940kg of sand were removed from the three pressure vessels. It is a new activity for ALTRAD Africa, and we took this opportunity to invite other clients such as TOTAL E&P.
Hereafter, the images highlight the scale/solids built up within the vessel internal surface areas pre/post desanding operation. By removing more than 800kg of sand/solids and cleaning the internal surface areas using the “Altrad Intrusion tool”, we can see significant temperature change from the image taken post operations.
