Evolution of autonomous maritime operations driven by automation technology and digitalisation
Background, prerequisite and first visions of autonomous ships Radio communication for maritime industry started to develop in the beginning of 1900. 1910-1970 was the period for development of radio communication, gyro compass, radar and heading...
Does the ship design project benefit from Digital Twin approach?
I have been thinking what benefits shipowner and yard gets if they start concentrating to digital twin approach at early design phase. At least then virtual ship will be matching the real one more accurately....
Fuel cells
The marine industry is well-known to be a significant source of harmful local (NOx, SOx and particulates) and global (mainly CO2 and CH4) emissions. The high emissions are a result of the traditional low grade...
Visualization in passenger vessel design – Virtual world gaining on physical
Visualization is an incredibly versatile concept, and with new and evolving technology, it is safe to say that the usage of visualization will only increase and diversify further. It has the potential to become a superior tool of communication...
Fuel savings through hydrodynamic improvements
A typical cargo ship that operates 24 h/day and 300 days a year uses about 95 % of its energy for propulsion. Fuel consumption for propulsion is 28 800 ton-MGO/year/ship, which translates to annual fuel expenses of...
The ballast water issue cannot be wished away – here’s why
The same questions and claims regularly come up when talking about ballast water and its treatment. “Ballast water has been transported ever since ships were invented”, or “The invasive species have already been transported so...
Sulphur Emissions – Does one ship pollute as much as 50 million cars?
A recent eye-catching headline that did the rounds in LinkedIn’s marine community suggested that one ship emits as much sulphur as 50 million cars. Another frequently seen statement is that the sixteen worst offending vessels...
