Vertical Lay Systems

Portability in pipelay gains a new name, with the arrival of the award-winning MDL PVLS.

The Portable Vertical Lay System is the first truly road-transportable VLS on the market, which can travel in modules to meet the product reels at their home ports, before being reassembled on the quayside.

All the ancillary equipment is pre-installed before the system is lifted onboard, either mounted over the moonpool or the side of the vessel. This results in quick mobilisation and demobilisation once the project is complete.

The result is a self-contained and compact Plug&Play solution, modifiable to suit varying line-pull requirements, operational weather windows and types of product handled during every individual campaign.

Design Considerations

• Type of vessel / operating conditions
• Deck mounting (overside/through moonpool)
• Vessel deck loading capacity
• Maximum installation and recovery loads
• Product outer diameter
• Co-efficient of friction of the product
• Operating product line speed
• Preferred drive option (hydraulic / electric)
