Replacement Mud Standpipe Manifold for Sakhalin

Working with our Russian partners RBV Energy have recently shipped a replacement mud standpipe manifold to Sakhalin. RBV Energy provided a full turnkey package including design, material supply, fabrication, assembly and testing. We worked with our client to asssit with their design changes whilst still maintaining the critical interface points.

Front end design

From the enquiry stage we assisted the client with the design of the replacement manifold. The mud gate valve sizes that our client were using were non-standard and many other vendors were offering these on a significantly longer lead time. RBV Energy were able to offer these valves on a shorter lead time which meant the delviery of the manifold suited the clients shutdown schedule.

Fabrication

In order to provide our client with the correct flanged end valves they needed to mate with the existing pipework we welded specially machined API 6A flanges onto butt weld valves.

Mud ate valves with special flanged ends We provivded regular updates to our client, including biweekly conference calls, and they witnesses many of the critical path activities including fabrication.

Disassebly for transport to site

As the manifold we supplied was to replace an existing manifold our client asked us to handle dissassbly for shipping to site. The parts were packed so our client could easily reinstall when everything arrived offshore. Exploded Overhead Views of Disassembled Standpipe Manifold
