Civil construction works

Civil operations are carried out under sheltered conditions, e.g. in ports, rivers or waterways.

Civil constructions works include the following activities:

  • Construction and dismantling of large structures, such as bridges;
  • Transportation, lifting and placing of tunnel elements and caissons;
  • Lock door lifting and installation;
  • Concrete barrage construction.

Stacking operation at a yard in Norway
Stacking operation at a yard in Norway

Mid February 2017 Rambiz executed the stacking operation of a drilling module S-620 onto its substructure S-610 at a yard in Norway. Total weight of the drilling module was 1330 T.

Through a good cooperation between Rambiz crew and client an accuracy within millimeters could be achieved.

The complete drilling unit is part of the “Johan Sverdrup” offshore platform.

Liftting of a tiltable pipe lay system

The lifting operation was executed on October 4, 2016 at Huisman in Rotterdam (Schiedam), the Netherlands. The 2430 tonne tiltable pipe lay system was lifted from its construction location on the Huisman quay, transported to its designated location on the Scanid Buzios and put into position. It was a challenging project as all this was carried out with a maximum allowable tilt of 0.4°, limited space for HLV in the harbour and a 2mm tolerance for installation. Huisman’s preparation and the impressive cooperation between Scaldis and Huisman ensured that this challenging project was a success.

Lifting of 2 modules onto a FPSO vessel

Rambiz lifted a Boiler (800T) and a STG (600T) module onto the FPSO "Enquest Producer" in the Blohm+Voss yard in Hamburg. One module was located on the quayside and the other was on a floating dock.

HLV Rambiz positioned both modules with an accuracy of millimetres.

Lifting and installation of a drilling tower onto the Globetrotter II
Lifting and installation of a drilling tower onto the Globetrotter II

This lifting operation was executed at the premises of Huisman in Rotterdam (Schiedam), the Netherlands. The project consisted of lifting the 2600 tons drilling tower from its construction quay and transporting it to its designated location on the drilling vessel "Globetrotter II".

A three point lifting configuration constructed far below the centre of gravity made this project unique and challenging.  The inclination of the entire structure had to be continuously monitored in order to guarantee, the stability of the lifting configuration.

Comprehensive preparation in coordination with Huisman made this lifting operation a success.

Immerge, towing and installation of tunnel elements for the Coentunnel 2
Immerge, towing and installation of tunnel elements for the Coentunnel 2

This project involved re-floating, transportation, submerging, and positioning of four concrete tunnel segments. The segments were then stabilised by inserting sand underneath them.

Lifting, transportation and placement of 150 bridge elements for the Vasco da Gama bridge
Lifting, transportation and placement of 150 bridge elements for the Vasco da Gama bridge

The heavy-lifting programme for the bridge construction of this remarkeble project required the positioning of 150 girders, each with dimensions of 80x16m and weighing up to 2200 tonnes. The girders were transported on the large main deck under the two main cranes.
