1. The Enemy Below - Adhesion and Friction of Ship Hull Fouling
Abstract : Below the waterline, commercial ships are good targets for marine organisms to attach and proliferate, a problem commonly known as biofouling. A fouled hull means higher hydrodynamic resistance, which can result in significant fuel penalties. READ MORE

2. Roughest hour – approaches to ship hull fouling management
Abstract : Submerged surfaces at sea are colonized by a high diversity of sessile (i.e. attached) life forms. As the merchant fleet capacity increases, responding to growth in demand for seaborne transport, so does the hull wetted surface area that is prone to colonization by these sessile organisms, i.

3. Efficient Full-Scale CFD for Ship Hydrodynamics
Abstract : An efficient numerical approach for ship hydrodynamics, involving a hybrid free-surface potential flow/RANS method, is explored. The work focuses on estimating the delivered power of ships in calm water and in waves, highlighting the benefits of full-scale simulations, particularly for ships with Energy Saving Devices.

4. A Generic Model for Simulation of the Energy Performance of Ships - from Early Design to Operational Conditions
Abstract : Forecasts show a doubling of the world’s transportation needs until 2050. Shipping today accounts for 90% of all freight transport. Simultaneously, shipping must become cleaner and more energy-efficient to meet the target to more than halve 2005 greenhouse gas emissions by 2050. READ MORE

5. CFD Predictions Including Verification and Validation of Hydrodynamic Forces and Moments on a Ship in Restricted Waters
Abstract : The evaluation of ship manoeuvrability is of significance at the initial design stage, as inappropriate manoeuvring performance may result in unstable ship motion, difficulties in steering and even marine accidents. Restricted waters, with the presence of solid boundaries of the flow field, such as a shallow seabed below the hull or a side bank in the vicinity of the hull, complicate the flow field and introduce an influence on hydrodynamic forces and moments acting on the hull.
