SHIP SURGEONS

Ship Steering

Ship seakeeping

• Maximum speed in a seaway: 'involuntary' speed reduction due to added resistance in waves and 'voluntary' speed reduction to avoid excessive motions, loads etc. • Route optimization (routing) to minimize, e.g., transport time, fuel consumption, or total cost. • Structural design of the ship with respect to loads in seaways. • Habitation comfort and safety of people on board: motion sickness, ...

SAR Imaging of Ship Wakes and Inverse Ship Wake Problem

Airborne Synthetic Aperture Radar (SAR) images of sea surface often reveal ship wakes, which appear in a form of bright and dark streaks. It is believed that some of them pertain to the ship generated Kelvin wave system and some to the ship turbulent wake (Reed et al., 1990). The streaks in SAR images are sufficiently narrow to consider them as straight segments. Assuming that the location and ...

Ship Voyage Energy Efficiency Assessment Using Ship Simulators

The increase in global trade is driving growth in both the size and number of ships. However, this increased demand is leading to greater contributions from shipping to air pollution. This is leading designers and operators to propose and adopt novel powering and propulsion systems. However, there is a challenge with assessing the actual benefit from using a certain retrofit technology or chang...

Effects of Ship Motion on Ship Maneuvering in Waves

Ship maneuvering performance is typically predicted in calm water conditions. This provides very valuable information at the initial ship design stage. However, since the ship always sails in waves, the maneuvering performance of the ship in seaway may be significantly different from calm water condition. Therefore, if the effect of waves and the corresponding motion responses can be included i...
