MV Juanita platform supply vessel

MV Juanita is a new platform supply vessel (PSV) of the SALT 100 PSV design, constructed by Kleven Maritime for its owner Ugland Offshore. The vessel is being chartered by Statoil under a two year contract, which is extendable by one more year.

Kleven Maritime was awarded the construction contract in June 2012. The vessel was launched at Kleven Verft shipyard, Ulsteinvik, in September 2013, and delivered in April of this year.

The vessel integrates a new propulsion system based on permanent magnet technology, developed by Inpower in collaboration with Scana Volda, with innovative solutions for cargo handling. The new PSV is a contender for the Ship of the Year title, which is to be awarded by Skipsrevyen in September.

The vessel implements SCR catalyst systems based on urea to cut down nitrogen oxide (NOx) emissions.
