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
