Nauta launches LNG PSV

The new vessel, Siem Symphony, is being built for its Norwegian client Hellesøy Verft. It is of VS 4411 DF design with an overall length of 89m, a beam of 19m and a maximum weight of 5,500 tonnes.

It has been designed in collaboration with Wärtsilä Ship Design and will have a dual-fuel system for the use of either LNG or marine diesel oil.

With an optimised hull design, Wärtsilä vessels will feature lower fuel consumption, reduced fuel costs, and fewer exhaust emissions compared to vessels running on conventional marine fuel.

Wärtsilä will also supply the complete diesel electric system, the Wärtsilä LNGPac gas storage and handling system, and the complete electrical and automation system, including a four-split Wärtsilä LLC (Low Loss Concept) solution.

The PSV will also be equipped with the modern solutions for firefighting and emergency responses, and will have a deck of around 970m² and under deck capabilities suitable for operations on the Norwegian Continental Shelf.

After final outfitting, the PSV will be operated by SIEM Offshore.
