STS Operations are becoming more common around the world, for instance off the US coasts and northern part of Europe (including Baltic and Arctic waters). A leading lightering company is Skaugen PetroTrans, Inc that executes some 900 STS operations a year. Experienced Mooring Masters claim that such operations are carried out with any type and combination of tankers, all individually different because of weather conditions, sea states, manoeuvring performance etc. Mooring Masters also claim that differences in interaction between vessels are significant.Importance of knowing exactly what’s going on on board the ships is essential for conducting a safe and efficient STS operation. In the future, other types of STS operations are anticipated to take place, e.g. tandem configurations.
The overall objective is to develop a decision-support system, based on the principles of an automatic control system, for the Mooring Master and ship navigation officers in order to enhance operational safety and efficiency. The system shall be suitable for training of STS operations on simulators as well as on board actual ships.
