Viking Star Ocean Cruises Istanbul

Update, 11:35 p.m. EDT: Viking Ocean Cruises has confirmed that Viking Star remains in Tallinn after a mechanical issue. "The mechanical issue is related to the electric transformers in one part of the ship's propulsion system," the statement reads. "Engineers are working onboard, but because repairs are expected to continue through the weekend, Viking has decided to cancel the remaining portion of this cruise. All guests onboard were informed earlier today and have been offered options for continuing their journey to Bergen or returning home from Tallinn at Viking's expense. This specific mechanical issue is highly unusual, and all guests will receive compensation for the inconvenience." Viking has not yet determined whether any changes to Viking Star's upcoming cruise schedule is necessary, but will be in contact with any affected cruisers.

According to a post from Viking on the Cruise Critic message boards, passengers who do not wish to return home immediately can stay onboard Viking Star until Tuesday, at which point, Viking will fly them to Bergen and put them up in a hotel for the remaining days until the original debarkation date of August 8.

(2:27 p.m. EDT) -- Cruise Critic members onboard Viking Ocean Cruises' Viking Star have posted on our message boards that engine troubles have delayed the ship in Tallinn, Estonia. After two nights in port, passengers have been given the option of going straight home or remaining onboard in hope that the ship will be able to sail to Bergen, Norway, in time for its next departure.

OBX Cruisers first reported that Viking Star arrived late in Tallinn on Thursday because the ship was sailing at reduced speed, and that engineers began working on the ship once it docked. Today, iggy25 posts, "Actually now the trip has ended in Tallinn." HMforcruise adds, "We have just been advised from Viking that the mechanical issues can not allow us to leave Tallinn until Aug. 4 at the earliest. Then we go straight to Bergen arriving late Aug. 7. Thus all ports of call cancelled. Options either stay on or let Viking arrange air out."

Viking Star was sailing a 14-night Viking Homelands cruise from Stockholm to Bergen. The ship visited Helsinki and St. Petersburg before getting stuck in Estonia; it will miss calls on Gdansk, Poland; Berlin (Warnemunde), Germany; Copenhagen, Denmark; and Alborg, Stavanger and Flam, Norway. The next cruise is scheduled to set sail from Bergen on August 8.

We have reached out to Viking Ocean Cruises for more information and will update when we hear back.
