The Dutch supplier will provide its advanced Telescopic Access Bridge (TAB-L2) gangway system as well as the powerful 50t Offshore Knuckle Boom Crane (KBC-L) with 3D motion compensating.

PS> Looking at the number of exhaust pipes that must mean “diesel-electric”, or the illustration shows an early version of the design.

And then there will be three:

PS>A bit surprising that a German yard could haul in a contract from a S.E.Asian client, but it just shows that European yards can compete on specialized vessels like this

Would be interesting to see the equipment list for this vessel.

The hull for yet another Cable Lay Vessel (CLV) has arrived at Ulstein Shipyard from Crist hull building yard, Poland:

Large capacity and high capabilities

The Nexans Electra, designed by Skipsteknisk, is based on the Nexans Aurora, which was delivered by Ulstein Verft in 2021. She is specifically designed to transport and lay Nexans submarine products, including cable bundles, as well as perform recovery and repair of such products. The vessel can perform effectively in challenging weather conditions and boasts exceptional manoeuvrability and station-keeping characteristics. The incorporation of high-capacity shore power systems, an energy storage system, and biofuel compatibility ensures a reduced environmental footprint.

The fact that the Marmac 306 was built domestically means that it can transport cables within the US and bury near-shore cable where that would be illegal for a foreign vessel. The barge is exactly the kind of ship the US needs to build its capacity to power coastal cities without warming the climate.

Maybe not entirely "industry-first:

Here are the other Nexan CLV the barge will support:

PS> DP barge? If the barge has thrusters to keep station on DP, shouldn’t it be classed as a ship?
