Ultra-long lifetimeprototype compensator
Compensator for 20 years of uninterrupted seafloor performance
Overview
The development of a pressure compensation technology capable of delivering uninterrupted seafloor performance for a duration of more than 20 years
Our client Siemens AS required a subsea compensator capable of delivering uninterrupted seafloor performance for a duration of more than 20 years. Even though our “regular” compensators are designed to achieve high levels of reliability, the delivery of a subsea compensator that would meet our client’s requirements demanded a different design approach.
During the project, our mechanical engineers made sure to consider every detail of the compensator’s design: from the influence of marine growth on durability, to the safe and controlled assembly of the spring-loaded parts. Following assembly, the compensator was subjected to extensive testing and qualification programmes, including pressure testing, functional testing, temperature testing, contamination testing, and dynamic operations testing. Our in-house extensive qualification programme guaranteed the uninterrupted long-term performance of this mission-critical system.
