Courses: Offshore Hydrodynamics and the brand new Ship Hydrodynamics II


Following the popularity of MARIN’s hydrodynamics courses, we have decided to launch a new course. Ship Hydrodynamics II will be held at our headquarters in Wageningen, November 2-6, 2009 (5 days).


Nowadays, ship design has become a hi-tech industry in which many complex calculation and testing methods are used to obtain the best result. For the modern naval architect it is important to know how these techniques work, to be able to ask the cor- rect questions to their suppliers and to ad- vocate the merits to clients. The advantages but also the limitations of CFD methods will be discussed. Other topics include the choice of the propulsor and its integration to the hull, interaction between propulsor and hull, propeller cavitation and erosion risk, propeller-induced hull pressure fluc tuations and energy saving measures.


The course is intended for the more experienced naval architect. Although recommended, it is not necessary to have attended the Ship Hydrodynamics I course.


MARIN will also again organise the Applied Hydrodynamics of Floating Offshore Struc- tures in Houston. This gives an overview of the latest developments, such as extreme metocean conditions, motion analysis and wave impact.

Retrofi ts – does one type ever fi t all?


Too many owners are fitted with ener- gy-saving devices that don’t fit their needs nor do they physically fit their vessel. Do retrofits exist which are actu- ally fit for purpose?


Certainly, it is time to focus on small invest- ments and on existing ships to save money on fuel. Slowing down can be an efficient option but it has its drawbacks and needs investment too.


Many claim savings can be made for every ship type in any circumstances. Throughout the years, MARIN has carefully assessed and model tested a large number of physi- cally sound devices and independently de-


termined their prospects for various ship types and operational conditions. No simple solutions exist. However, given the im- proved capabilities of dedicated CFD appli- cations, CFD, together with model testing, can result in significant savings. Full block, or slender ship types can benefit.


MARIN offers realistic advice, which starts with an initial, free assessment of possible gains on the basis of the ship lines and the operational profile of the fleet. A small re- port then offers specific advice for a given ship on the most promising device(s), as well as a description of the next step using CFD to explore the design and/or other tools and model tests.


MARSIM, Panama, August 17-20


MARIN executives will be presenting three papers at the International Conference on Marine Simulation and Ship Maneuverability (MARSIM), this year: “Anchor Handling Sim- ulation”, “Full 6-dimensional Modelling: a new Approach for Full-mission Simulations” and “Manoeuvring Mathematical Model for Ship Docking Module (SDM)”. Your views on these papers are most welcome.


OTC, Houston, May 5-8


MARIN will once again attend the Offshore Technology Conference 2009 in Houston. You are most welcome to visit us at the Dutch Pavilion, stand 2427. In addition, MARIN will present the paper “Evaluating the Loading and Structural Response of an Offshore Platform Using Integrated Large and Small Scale Testing Combined With Diffraction and Finite Element Analysis and Offshore Measurements” (May 7, session 19978)


Simulator demo


On 2-5 June MARIN will give demonstra- tions on a Compact Manoeuvring Simulator in Wageningen. This flexible system can be tailor-made to a large range of training requirements. Demonstrations will be given using the system for ASD tug training and for Anchor Handling purposes. For more information on the demo’s and the simulator capabilities please contact Noël Bovens, n.bovens@marin.nl
