MOHO NORD MPI PROJECTOverview

Total split Project Overall SURF SOW

SOW tailored to a Mid Size Deep Water ConstructionVessel such as Normand Vision

Optimization of the execution plan (Transport &Installation in one phase)

Very competitive pricing of relevant SOW

Adding to our strong and successful track record inSURF projects

Systematic and meticulous approach to new countriesentry

Safe, on time, on budget project execution

Sucessful for Total and Ocean Installer

SAME CAN BE DONE FOR DEEP WATER SOW’s IN EGYPT
