Qceas works in the civil and maritime diving industry

Home / About us

Skills, equipment & experience

We are contractors and supervisors of projects in the maritime and civil sector, i.e. civil projects where underwater work is unavoidable. This includes the supply and installation of bridges and lock gates and the underwater construction of building pits for tunnels, car parks and bridge piers.

Qceas is particularly specialised in the anchoring of floating and submerged objects. It has developed a patented alternative to placing objects on the ground. This method lends itself to a wide variety of purposes, such as anchoring FPSO’s and both temporary and permanent anchorages for ships.

Qceas drills these points very accurately. Depending on the forces that an anchor must be able to bear, Qceas can realise a single holding force of up to 300T per anchor.

The anchor points can be installed in almost all soil conditions.

Qceas also takes on the sinking of caissons. Qceas can take on such a project in its entirety, including both the driving and towing of the caissons to the location, and the positioning and sinking thereof.

Qceas is also able to take on a ‘building pit complete’, which means that it takes on all the preparatory work that results in a dry building pit. This preparatory work includes placing sheet pile walls, excavating the cofferdam, placing pile foundations and pouring underwater concrete.
