新JIP:海上间歇无人值守驾驶台
JOIN THE ALERT PROJECT: SAFELY LEAVING THE NAVIGATION BRIDGE UNATTENDED FOR PERIODS OF TIME WHILE AT SEA Within the new JIP initiative Alert we will determine the conditions for when it is safe to periodically leave navigation spaces unattended and at the same time examine whether that improves the safety, working and living situation for the crew […]

abstract = { new Joint Industry Project (JIP) has been initiated recently by MARIN, called ESD-JILI (机理), looking into the working principles and scale effects on Energy Saving Devices (ESDs).
Three ESDs have been chosen for the investigations in the first phase. They were a preduct with a supporting stator in the duct, a pre-swirl stator with asymmetric blade design and Propeller Boss Cap Fins (PBCF). Measurements of forces and moments on all components of the ESDs have been carried out in selfpropulsion model tests with dedicated sensors. Particle Image Velocimetry (PIV) technique has been used in the investigation of the detailed flow around the ESDs. In order to investigate the scale effects in model tests, a fullscale wake field was approximated by a ‘smart ship model’. Computational Fluid Dynamics (CFD) calculations were carried out both for designing the smart ship model and also for the detailed flow around the ESDs. Some findings and fundamental issues on scale-effects of the ESDs are addressed in this paper. },

abstract = {Ships are in general designed to first meet their contract speed, which is most times their trial speed. The ship design efforts are dominated by the focus to attain this trial speed. The resulting hull lines design philosophy will most likely not result into the most full efficient design in service conditions. Increasing fuel costs and low freight rates drive the need to design ships for their service conditions. It's operational draughts and added resistance due to waves that should be the key drivers for a successful modern ship design. The last years MARIN has tested and expanded its tools and capacities to support hull form design for minimal fuel consumption in everyday use, minimizing SOx and NOx emissions. Tools suchs as viscous flow calculations in an explorer mode, calculating numerous hull form variations overnight in order to maximize the performance of the vessel, and voyage simulations to determine true service margins are essential when designing a ship.},
