The Basto-Iv has faced technical challenges recently that highlight the ongoing pressures within the ferry operations on the busy Horten-Moss route in Norway. On March 16, 2017, ferry operator Bastø Fosen reported that the Basto-Iv's counterpart, the Basto VI, went out of commission due to technical issues. This incident not only reduced the ferry capacity of the route but also underscored the critical need for reliable vessels on this vital transportation line.
Adding to the woes, on May 22, 2017, both the Basto-Iv and the Basto VI were sidelined due to different technical problems, leading to long queues and significant delays for commuters wanting to cross the Oslo Fjord. The Basto-Iv's issues were particularly concerning as an oil leak in its main engine resulted in it being stationed in Moss for further inspection. Meanwhile, the Basto VI encountered difficulties connecting its propeller, compounding the service disruptions during a peak travel time for locals.
These incidents have drawn attention to the recent developments in ferry capacity along the Horten-Moss route. In light of new operational requirements mandated by the Norwegian Road Administration, Bastø Fosen has sought to modernize its fleet. The company is in the process of integrating larger and more environmentally efficient vessels into its operations, including new builds from Cemre Shipyard, aiming for a capacity of at least 200 PBE (passenger car equivalent) for each ferry.
This emphasis on upgrading the fleet stems from a newly awarded contract which requires that Bastø Fosen maintains a minimum of six ferries, ensuring higher capacity and adherence to environmental Tier III standards. With the Basto-Iv and its fleet aiming to meet these challenges, the focus remains on delivering reliable ferry services that can withstand operational pressures and fulfill the growing demands of passengers.
