There are extensive regulations governing safety and environmental work for international ferry operations. Stena Line’s operations are conducted in accordance with legal requirements and the company works continuously to strengthen the safety of personnel and ­passengers. During the last year, Stena Line has participated in a project aimed at improving safety for passengers even after they have driven off the ferry.

Every year, Stena Line’s 40 vessels are subjected to over a hundred inspections by representatives from different maritime safety authorities and classification societies. Most of these inspections are carried out with­out any major observations. However, in September 2013, Stena Alegra, chartered to operate on the Karlskrona – Gdynia route, was detained in port when certain deficiencies were found. Stena rectified the deficiencies immediately and the ship was back in service the following day.

At the end of August 2013, an automated sobriety checkpoint was opened at the Stena Line terminal in Majnabbe, Gothenburg. Since then, both truck drivers and private motorists travelling on Stena Line ferries have been required to drive through a station equipped with measuring equipment to monitor their breath.

If the breath sample gives a negative reading, the barrier is not raised for the vehicle and the relevant authority representative is called to the scene. During the trial period, 8,745 drivers have been tested, with ten of them reported for suspected drunken driving or extreme drunken driving. The trial period was concluded at the end of the year.

The project is led by the Swedish Abstaining Motorists’ Association (MHF) in cooperation with the Coast Guard, Police, Customs, the Swedish Transport Administration, Servotek and Stena Line.

Shore-based power expanded with district heating

In several ports where Stena Line operates, it is possible to connect the vessels to shore-based power when they are berthed. This allows the auxiliary engines on board to be turned off, which saves oil and reduces carbon dioxide (CO2) emissions.

In 2013, Stena Line also began a joint collaboration with the City of Gothenburg and Göteborg Energi to explore the possibility of connecting Stena Danica to the district heating network. This is the first time that district heating is connected to a vessel in operation. The district heating will initially replace the dieselpowered boilers that are currently used. The plan is to eventually use district heating also for hot water and keeping the engines warm.

In 2013, the total effect of Stena Line’s use of shore-based power resulted in a saving of approx. 4,600 tonnes of oil. Had oil been used instead, it would have generated sulphur dioxide (SOX) emissions of 9 tonnes and CO2 emissions of over 14,700 tonnes, which is equivalent to the CO2 emissions from about 5,400 cars during a year.

Use of district heating is expected to reduce CO2 emissions by 75 percent, from approx. 800 tonnes to 195 tonnes of CO2 per year. A reduction in the level of noise from the ship is also expected, which is important in view of Stena Line’s central location in the port of Gothenburg.

Monitoring fuel consumption

During 2013 the work with Stena Line’s Energy Saving Programme (ESP) has continued. The programme was intro­duced in 2006, with the aim of reducing energy consumption by 2.5 percent each year. A number of different projects connected with the programme are in progress. In 2013, for example, modern new flow meters began to be installed on several vessels, with the aim of monitoring on board fuel consumption in closer detail. The flow meters are connected to a larger system, the Fuel Management System, which also measures parameters such as water depth and water currents. With information about the water depth the ship officers can optimize the speed, as a high speed in shallow passages increases fuel consumption.
