Challenge
ENSCO required the cleaning and long term, outdoor preservation of 1 Annular and 2 BOP NXT double bodies. The equipment was to be stored outdoors, at a coastal storage yard in the UAE where temperatures can regularly exceed 50C and upwards of 100% humidity is not uncommon in summer. Both internally and external preservation with a tried and tested solution was required.
Application
Cortec’s time proven VpCI products were proposed to Ensco to mitigate the effects of corrosion for the annular and BOPs. The preservation work took place in a GAC yard, Mussafah, Abu Dhabi. Lifting lug access was maintained so that equipment could be moved from GAC yard to permanent storage as required by ENSCO.
- Equipment was hand cleaned and then with brush a solution of VpCI-414 was used to prepare the surface for the new coating.
- VpCI-386 was applied to all painted surfaces and VpCI-368 on all bare surfaces
- Internal void spaces were protected by placing VpCI-308 pouches inside the cavity
- Equipment was wrapped with MilCorr shrink film to prevent the ingress of dust to the unit and provide additional corrosion protection.
Conclusion
Equipment was effectively and efficiently preserved with Cortec products at the yard where they were stored. Following which they were moved to a new storage location, access to lifting lugs was maintained and the MilCorr wrap was durable enough that it did not tear or rip during transit, satisfying the client.
