Scope of Work:

Removal of residual hydrocarbon & pyrophoric material.

ProDecon® Method

Two successive decontamination cascade washes, stepped circulation of selected sections followed by an additized cold water rinse.

Chemistry used:  

LDP-88™ (ProDecon® Decontamination Chemistry).  Cacl₂ (to fracture the temporary emulsion on route to the effluent holding tanks) and ProDecon oxidizing agent to treat any remaining FeS

Safety performance:

Excellent. No incidents, no lost time first aid, no reported near misses

Environmental performance:

Excellent. Following initial treatment with Cacl₂ and processing through ProDecon’s Mobile Waste Water Treatment Unit, the effluent was analysed by client, found to be compliant and was released for metered discharge to the VBU sump with no adverse environmental impact. 

Customer verified results:

References may be available on request. The following comments are taken from client witnessed Completion Report.

Vessel pre-entry checks:         

Zero H₂S, Zero LEL, Zero CO and no hydrocarbons.

Vessel internals:             

“Very clean...allowed Immediate entry on opening”...,

It was noted that there was less residual chemical odour than when other decontamination chemistry had been used and there were no complaints regarding irritation from those working inside the vessel. Unlike our customers experiences with other chemistries, ProDecon® LDP products caused no vessel entry delays and no interference to sampling and monitoring equipment.
