Viktor Lenac Shipyard has successfully
completed a complex conversion of the cable lay barge 'Cable Enterprise'
for Prysmian Powerlink Services Ltd, UK, a subsidiary of Prysmian Group.
The barge was redelivered on 13 March 2015 on mutual satisfaction of the
owner and the shipyard having a total project value exceeding 22 million
Euros.
Viktor Lenac won the contract for conversion
of the barge 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, aft engine room section to accommodate
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 now Bulbous Bow. Within
two new decks on the accommodation block, fully equipped Bridge Control
Room and additional accommodation facilities have been arranged. A total
of 155 tons of pipeline and 145 km of electrical cables was installed.
The barge has also been extended for 10 meters.
In addition, sophisticated cable lay
equipment was installed 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, commissioned 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. 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 lay cables in an oil
field in front of Santa Barbara, California for Exxon Mobile, one of the
world's largest company, as her first job after the conversion.
Conversion of Cable Enterprise is the
most demanding one from technical point of view. It was completed in record
time. Viktor Lenac Shipyard has proved once again that it can execute the
most complex projects for the world's most reputable companies, further
consolidating its position as one of only a few specialized shipyards for
conversion of ships and construction of gas production platforms in the
Mediterranean and beyond.
