Offshore pipelinemaintenance typically falls into one of four categories:
valve replacement, tie-in, riser repair,or heavy lift protection.
During these types ofmaintenance,operators rely on non-intrusive inline
isolationmethods to protect their people,achieve compliance,andmitigate
reductions to production. Themost common isolation is theDNV-certified
double block andmonitormethod,as seen here.

DNVRecommendedPractice forPipeline
SubseaRepairCriteria (DNV-RP-F113/3):
. Each barriermust be able to retain full line pressure
. Independent locking system
. Sealmust be independently tested
. Ability tomonitor line integrity
. Sealsmust be independent
from each other
Through the use
of independently operated isolation
barriers and continuousmonitoring,the system allows high-pressure
pipeline operators to carry out remedial
pipelinework in a safe,controlled,andmonitored environment.
