MPL
Currently deployed by Aker BP on the Valhall Flank West and Hod B platforms, the MPL is essential for Unmanned Installations. It allows remote operation from the central platforms or onshore facilities, ensuring continuous functionality without on-site personnel.
Multiple Pig Launcher
The MPLs on VFW and HOD B Platforms are equipped with six PSBs, allowing it to launch five de-waxing pigs individually remotely when needed. Currently, the pigging interval for these pipelines is every two weeks, requiring visits to load new pigs into the MPL approximately every ten weeks.
Remote Operation
These NUI platforms cannot operate unmanned without the Tech Trade MPL which is designed to operate remotely, controlled from either their central platform or from land.
Specifications
Tech Trade are currently delivering a 28” 1500# MPL using 8” CFT PSBs. The 8” PSBs were specifically developed by CFT & Tech Trade for larger MPL. The MPL package is scheduled for testing in May 2025 and represent our continued development of MPL technologies.

Understanding Project Requirements
It is always important for each application to verify that the PSB can provide sufficient flow to launch each pig and that the pig stop spool is dimensioned with sufficient travel to retain the pig in place when necessary. CFT have calculated Cv values available for their range of PSBs and Tech Trade normally recommend that we conduct a short paid study to carry out verification that the PSB and MPL are correctly dimensioned to reliably launch the pigs.
In the study we would set up a team with CFT, Tech Trade and the customers project teams so that we can gather current operational data of the pigs being used. Tech Trade and CFT would prepare a verification report which would help all parties understand if there are any risks or challenges associated with employing MPL technologies to replace a conventional pig launcher.
Tech Trade can also assist the project team with information package that will help with the integration of the MPL on the platform. Typically the following information as listed below is important for us to evaluate any application for MPL.
MPL Operation
- What is the expected frequency of launching pigs?
- How often are personnel expected to be on-site for operations or maintenance?
- Are there specific operational windows or constraints that dictate when pigs can be launched?
- How does the Customer want to control the MPL (LCP or through Platform SAS, remote SAS etc.)?
Pipeline Specifications
- What is the diameter, thickness and material of the existing pipeline?
- Are there any unique pipeline characteristics or operational conditions we should be aware of (e.g., pressure ratings, temperature ranges, or fluid properties)?
Pig Specifications
- What types of pigs are expected to be launched from MPL?
- How much fluid does the pigs by-pass?
- Will there be dual-module pigs?
- Pig dimensions (length & diameter)
- Pig weight
Power Supply (PSB Actuators)
- What type of power supply is available at the installation site (e.g. electrical, pneumatic)?
- Are there any specific actuators we should consider? On our previous supply we have used Electrically powered Actuators from ROTORK and BIFFI.
Space, Access & Installation
- What space is available for the MPL and Pig Handling facilities?
- What lifting facilities are available for handling pigs and pig handling facilities?
- Are there any logistical considerations (e.g., space constraints, transportation of the MPL, crane access)?
Safety Considerations
- Are there any specific safety regulations or operational guidelines that need to be considered during the loading of the MPL and launching processes?
- Are there any specific requirements for Fugitive Emission?
Testing and Commissioning
- What are your expectations regarding the testing (FAT) and commissioning (SAT) of the MPL?
- Will there be a need for on-site service personnel for support during these processes?
Training, Maintenance & Support
- Will personnel require training for the operation and maintenance of the MPL?
Project Timeline
- What is current status of the project and what is the timeline of the Project?
- What is the anticipated timeline for the procurement of the MPL? A typical lead time for an MPL package is currently 70 weeks from PO.
- When would a fixed and firm offer be required?
