Subsea Power Switch-Technology for the Life of Field

摘要

Failures of subsea equipment are a major concern for operators. The cost to retrieve and repair system components increases dramatically for submerged equipment. Critical subsea failures result in loss of production jeopardizing the availability of subsea production systems. System availability is one of the key success criteria during the lifetime of a subsea field. A major area of focus is electrical failures of subsea equipment. Loss of production and high cost of intervention motivate operators and service companies to seek technologies which will reduce the probability of failure and maximize overall system availability. To address these challenges a novel type of subsea power switch is introduced by OneSubsea. The switch combines innovative electronics and software design enabling automatic and independent isolation of electrical faults. Incorporated into the subsea control system, the Power Switch automatically shuts off faulty subsea consumers without interruption to adjacent wells powered from the same source. Providing continuous monitoring of individual subsea consumers the Power Switch gives the operator flexibility and advanced warnings about the status of the equipment. The device gives the operator the ability to continue production from a field affected by multiple critical electrical failures.
