Cable Enterprise

Italian company Prysmian Group has upgraded its Cable Enterprise vessel from a moored cable laying barge into a DP2 cable laying barge.

After conversion, the vessel will be equipped with 8MW of power to manoeuvre with its own propulsion system.

Cable Enterprise is now capable of retaining its position in dynamic positioning (DP mode), even at the time of bad weather conditions.

With its powerful propulsion system, the vessel will be able to undertake lay and burial operations with different types of plough, including HD3 ploughs.

The submarine cable laying barge also maintains its ability to ground out and operate even in shallow waters.

Following the upgrade, the vessel can also operate on its own without the need of tugs during cable installation activities.

"Our objective is to further boost the group’s submarine project execution capabilities with a powerful and flexible asset that can install the entire range of submarine cables."

Equipped with seven independent positioning systems, the Cable Enterprise will be able to meet stringent operational requirements that are demanded by the oil & gas industry.

Claimed to be environmentally-friendly, the vessel can achieve an almost 80% nitrogen oxides (NoX) emission reduction.

As part of upgrades, new accommodation decks and operational areas have been added to the vessel, in addition to the installation of a new cable tank to increase its versatility for cable projects going forward.

In April 2014, Prysmian Group awarded a contract to Viktor Lenac shipyard for the vessel conversion works.

Prysmian Powerlink COO Raul Gil said: "Our objective is to further boost the group’s submarine project execution capabilities with a powerful and flexible asset that can install the entire range of submarine cables, from interconnectors and export cables to inter-array cables between turbines or offshore oil platform grid connections.

"With this newly upgraded vessel Prysmian is now fully equipped to meet this target."

A section of ExxonMobil’s existing offshore operations in the US will be supplied and installed with submarine cables by Cable Enterprise in DP mode, the initial project to be executed by the vessel.
