«Challange
In one of IK-Norway’s projects we had a delivery of a clamp that were going to be fastened to a platform structure 13m below sea level. The clamp structure was designed with 2 clamps opening/close, 2 locking cylinders which locks the clamps in closed position and wedging system in both clamps to create tension between the clamps and the platform structure. All these operations were operated by hydraulics. With so many operations (4 hydraulic cylinders and 12 torque motors) would require either a bundle of 32 hoses from the deck of the platform and down to the clamp (a total of 75 meters) or we had to install a ROV panel and have the ROV handle the operations. In shallow water closed by a platform this is very challenging and not recommended. With this information we challenged Envirex to come up with a solution for us.
Solution
Envirex designed a dual hydraulic panel that was remotely operated by computer where the operator could stand beside the HPU and perform the operations. This solution allowed us to send down only 2 hoses with a signal cable. The solution was tested several times prior to the installation without any sign of weaknesses. The system proved to be very stable and reliable. During installation the system worked perfectly.
Summary
Envirex proved through this process to be a company willing to take the challenge and solved it to our satisfaction. Both pricing and delivery time is always a challenge in projects like this but we met with a inspiring team that had everything under control. All changes was well communicated and looking into the facility you know straight away that this is a company that takes the HSE and Quality work to the next level. Envirex will absolutely be evaluated as a supplier in future projects by IK.»

Comments from AS Norske Shell regarding delivery of Universal HPU:
«HPU was used for pre-deployment testing of the x-mas tree, test and operate the subsea tree running tool (TRT) and Tree Cap Running Tool (TCRT). The HPU is very useful to all applications where water-based hydraulic fluid used. It is also used for pressure testing of small volumes
(<2 m3) with data logger connected to HPU t.
The simplicity of management and operation makes the device usable, very user and service friendly.»
