Ongoing operations for our ROVs LEOPARD and ROVJET810

Our 2 new ROVs LEOPARD were mobilized in May 2016 onboard the SIEM AIMERY (belonging to our customer Siem Offshore Contractors), with our ROVJET 810.

Since its mobilization, ROVJET810 has successfully completed the trenching of 59 cables with a total length of 62 km. The two work ROVs have provided assistance to the vessel’s operations : touchdown monitoring during cable laying, cable pulling in the turbine foundations, or installation of gravel bags.

Fitzroy Darwin project in Australia

2016-Darwin-3In February 2016, Louis Dreyfus Travocean performed for Alcatel Lucent Submarine Networks Ltd a Direct shore end landing in Darwin for the Fitzroy project.

Darwin is located in Australia, Northern Territory. The Fitzroy project is a fiber optic network between Darwin and Port Hedland for the Australian operator Nextgen with links to oil and gas platforms of the North West. Louis Dreyfus Travocean has previously performed the 2x44km separate shore end landing in Port Hedland, Western Australia, late 2015.

 

Darwin shore end consists of 3 kilometers of fiber optic cable installed from shore to a 20m water depth area through a 1 kilometer directional drill.

The installation was performed using a 16 meters x 7 meters barge locally chartered, fitted with 2 thrustmasters units. The work site, located just outside Darwin Harbor, is characterized by a strong tidal current and changing weather conditions at this time of the year. Crossing the Mindil beach dry sand bar, right on the cable route, was also a challenge for this operation.

Once cable installed on the pre-defined route, the barge has been modified and the TO Mobile trencher was mobilized onboard. TO Mobile is a dedicated crawler fitted with jetting system. This machine is operated from surface and the water jets are powered with a powerful pump on the barge allowing for the 2 meters burial depth target to be reached where the cable was not protected by HDD.

Schedule : January/February 20162016-Darwin-4

ILE D’YEU – Installation of 2 sections of cable

The Ile d’Yeu (Vendée, France) is supplied with electricity from the mainland by three cables, called YEU3, YEU4 and YEU5.

YEU3 and YEU4 cables have been mechanically damaged, and ERDF has decided to replace two sections, 3000m on YEU3 and 1800m on YEU4.

ERDF has awarded Louis Dreyfus Travocean for the management of the cable drums, the on-site transport and the installation of submarine cables on 2 km from the shore.

These new sections have been installed between the 19th and the 24th of September 2015 : each section of cable has been floated and towed up by boats along the route, the floats have been removed and the cable has sunk into its final position on the bottom.

LDTVO performed the following activities :

  • Mobilisation of TM04 trencher spread onboard the barge.
  • Loading of approx. 90 km of cable onboard the barge.
  • Double 44 km cable installation with simultaneous laying and trenching burial at 0.5 m (both cables in the same trench) in hard soil conditions / Calcarenite from the HDD (2 x 1,000m) entrances to the 10 m depth contour.
  • Surface lay with a minimum 5 m separation between both cables until the 15 m depth contour (at KP 44.604).
  • Installation of 200 m of articulated pipes.
