Laying a subsea pipeline or cable starts with the route: we survey the crossing, excavate, lay the line and protect it on the bottom. Subsea pipeline repair we do on site: fitting spool pieces, clamps and seals, making up flanges, welding and cutting underwater.

Laying pipelines and cables

We prepare the route, lay the pipeline or cable and secure it on the bottom.

  • Survey of the crossing route.
  • Excavation for the route.
  • Laying the pipeline and the cable.
  • Placing and fitting weights.
  • Forming berm protection.

Send a request
Do you repair pipelines underwater?

Yes. We fit repair clamps on damaged sections, replace spool pieces, make up flange joints and fit seals. Where needed, we weld and cut metal underwater.

How do you protect a pipeline on the bottom?

With weights that hold the pipe in place, and with berm protection.

Do you lay subsea cables?

Yes, the same way as pipelines: we survey the crossing route, excavate, lay the cable and protect it.

What if there is concrete on the route?

We cut reinforced concrete underwater and excavate the route.
