abstract = {The methodology and procedures are discussed on designing merchant ships to achieve fully-integrated and optimized hull-propulsion systems by using asymmetric aftbodies. Computational Fluid Dynamics (CFD) has been used to evaluate the powering performance through massive calculations with automatic deformation algorisms for the hull forms and the propeller blades. Comparative model tests of the designs to the optimized symmetric hull forms have been carried out to verify the efficiency gain. More than 6% improvement on the propulsive efficiency of an oil tanker has been measured during the model tests. Dedicated sea-trials show good agreement with the predicted performance from the test results.},

abstract = {The design of a say 5 year ‘young’ container ship is usually the result of an optimisation for maximum speed at design draught. Such design is mostly the result of an attempt to reach the contractual speed. However, a well balanced modern container ship should be a compromise between minimum fuel consumption and maximum cargo capacity across an intended or forecasted operational profile. In the design process, the focus should not only be on the calm water resistance and propulsive aspects but also the added resistance due to wind and waves should be considered, as well as the cavitation behaviour and related propeller induced pressure pulses. The SAVER 10000 developed for and in cooperation with the Canadian Owner Seaspan Ship Management Limited (Seaspan) is a pioneer in this new approach to balance the minimum fuel consumption and maximum loadability, taking into account the aspects as indicated.},

A flexible and effective definition of parametric hull form variations is used, based on interpolation between basis hull forms. All RANS computations were performed for full-scale Reynolds number. An initial optimization has been obtained neglecting the ship’s wave making. Clear Pareto fronts and trends in the solutions are obtained in a systematic variation study for the afterbody of a chemical tanker. In addition we performed a systematic variation using RANS free surface, to study the influence of wave making on the computed trends. As a result, a further decrease in the object functions could be obtained and another hull form appeared to be optimal.},

abstract = {The Maritime Research Institute Netherlands (MARIN) has recently started a Joint Industry Project (JIP) called ESD-JILI, investigating the working principles of energy saving devices (ESDs). Within the framework of this JIP, three ESDs have been selected and thoroughly investigated. They are a Pre-Duct with an inner Stator (PDS), a Pre-Swirl Stator (PSS) with asymmetric blade design and Hub Fins (HFs). The investigations have been carried out by using dedicated force and moment sensors to measure all the components of the ESDs independently during the propulsion tests, by using Particle Image Velocimetry (PIV) to measure the flow before, in-plane and behind the propeller and the ESDs, and by using Smart Ship Model technology (Wijngaarden 2011) to simulate the full-scale wake field during the model tests to gain insights on scale effects of the ESDs. At the same time, computational fluid dynamics (CFD) calculations are also carried out in order to further deepen the understanding of the working principles of the selected ESDs, and to assist the ESDs designs under certain guidelines. Some of the results of the study have been published to the Greenship’2011 Conference (Dang et al 2011). The flow details around the propulsion system with the PDS, which were obtained by both PIV measurements and CFD calculations, and the energy balance of the ship-propulsion system with a PDS are further investigated and reported here. Based on the results of the studies, the principle guidelines for ESD designs for single screw merchant ships have been proposed. },

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.},
