20ft Onshore workshop for hp gas/liquid testing of shut off valves with pressure isolated operator room

Purpose

  • Ready-to-use mobile workshops based on offshore containers are highly useful for maintaining of valves on the end-user site or on the offshore platforms during a shutdown or if a regular on call repair is required.

  • Modular design of mobile workshops allows to adopt them as per customer requirements and climate conditions. Workshops lineup allows to solve all kind of issues with valves overhauling at sites such as high pressure testing, calibration and maintenance of different kind of valves.

Tested valves

  • gate valves; 
  • ball valves; 
  • shut-off valves; 
  • check valves;
  • safety valves; 
  • control valves.


Complete set

1. Clamping system for PSV up to DN 300 mm (12").
2. Control station.
3. Computer registration system.
4. Portable machine for grinding and lapping.
5. Work station for valves assembling / disassembling DN 300 mm (12").
6. Jib crane.
7. Safety fence.
