Subsea pipeline project for SalMar in Trondheimsfjorden

Abyss has completed a marine contracting assignment to extend a subsea pipeline for SalMar’s smolt facility in Trondheimsfjorden.

In brief

Abyss completed a complex marine contracting assignment for SalMar, extending a subsea pipeline 6.3 kilometres into Trondheimsfjorden.

The pipeline was welded to the existing pipe system, secured with concrete ballast weights and lowered in challenging currents. The project was completed efficiently and as planned.

The project involved laying 6.3 kilometres of pipeline on the seabed to extend the existing discharge system into deeper water and meet the authorities’ requirements.

SalMar found that Abyss worked efficiently and independently, completing the assignment as planned.

A complex seabed installation

The new pipeline was welded to the existing pipe system and fitted with concrete ballast weights. Currents in the fjord made it essential to calculate the correct weight and plan the lowering operation carefully.

The assignment lasted several weeks and was completed as planned thanks to a team focused on finding solutions.

Connecting the subsea pipeline to the existing pipe system

Abyss’ marine contracting team has experience in offshore and inshore work, with expertise in lowering water pipelines and cables and constructing quay facilities.

The nationwide fleet makes it possible to use vessels already operating in the relevant production areas.
