Viktor Lenac Completes Cable Enterprise Conversion


Viktor Lenac Shipyard has successfully completed conversion of the cable lay barge ‘Cable Enterprise’ for Prysmian Powerlink Services Ltd, UK, a subsidiary of Prysmian Group.

As company reports, the barge was redelivered on 13 March 2015, with a total project value exceeding 22 million euros.

Viktor Lenac won the contract for conversion of the Cable Enterprise in February 2014 among seven notable shipyards from Singapore to Germany that were competing for this major conversion project.

The objective of the conversion was to upgrade a “dumb” cable lay barge with dynamically positioning capabilities (DP-2 Class). The non-propelled cable lay barge Cable Enterprise, built in 2000, used mooring system for station keeping and movement undertow whilst in the wind farm site.

During the conversion period of seven months, 1400 tons of steel was installed. Viktor Lenac also installed Aft Engine Room Section to accomodate two Diesel Engine driven Voith Schneider Propellers, Forward Engine Room Section with two Diesel Electric Generating Sets powering two Wartsila Azimuth Thrusters and two Tunnel Thrusters built in new Bulbous Bow.

Within two new decks on the accommodation block, fully equipped Bridge Control Room and additional accomodation facilities have been arranged. A total of 155 tons of pipeline and 145 km of electrical cables were installed.

The barge has been extended for 10 meters. Also, cable lay equipment was installed on Cable Enterprise, where Viktor Lenac participated in the production and installation of the pick up arm, a special device for stacking cables. The latest generation of equipment and automation systems have been installed, integrated, commisioned and completed with successful DP proving trials.

A sophisticated NOx reducing system, compliant with IMO Tier 3 standard, has been installed with Urea solution production plant, developed for this vessel, Viktor Lenac explained.

The barge is now on the way to Norway to load on the power cable, and then it is going to sail to the United States to conduct cable laying operations for ExxonMobil, as her first job after the conversion.
