Embedding

For the last 30 years the laying out and embedding of submarine cables and pipelines have been the main activities for JD-Contractor A/S. Accordingly we can offer a profound knowledge and a leading expertise within this field. When given an assignment, we use our unique embedding machines, which can quickly, carefully and safely jet or suck down cables or pipelines into the seabed. All our systems are developed with respect to the environment and leave no permanent scars on the seabed.


"SUBTRENCH TWO" makes trenches for new 400 kV Cable:

On our first mission with SUBTRENCH TWO, it trenched a distance of 6300 m. in the Great Belt.

"LIGHT-JETS": Our jetting units are driven over the seabed by water pressure.

A steering device makes sure that the jetting units do not move forward before the cable or the pipeline is down at the right depth.

"SUCTION-UNITS":

Our suction units are used if the trenching depth has to be deeper than 2 m or if the seabed is very gravely and/or consists of clay.

JD-Contractor A/S has chosen to use a system for the embedding of cables which we, after analysis, have found to be the most environmentally friendly and afterwards offers the highest level of protection for the cable.
