news ‘TOP’ optimisation of your
ship’s performance New program helps minimise fuel consumption
To expand MARIN’s services, a Trim Optimi- sation Program (TOP) has been developed. TOP helps customers minimise the fuel con- sumption of their ship by providing advice on the best trim at a given displacement.
It also shows the fuel consumption reduc- tion/increase when the ship speed is altered at a certain loading condition. TOP visualises the relationship between the loading condition and fuel consumption in an easy and understandable way. A screenshot of the user interface is shown in the picture beside.
This software tool is provided free of charge as part of trim variation model tests at MARIN. As well as results from model tests, CFD calculations can be used as input for the commercially available version. TOP can be used as a desktop version or installed on board a vessel and connected with a loading computer. Having TOP on board helps the crew develop awareness about real-time fuel consumption.
TOP has been developed in cooperation with the international shipping company Vroon. For more information contact Arno Bons, a.bo
OTC 2014 May 5-8
MARIN will again attend OTC in Houston. Meet us at the Dutch Pavilion at Stand No. 2427 to find out all about our offshore services. Join us for a drink on Tuesday May 6 at 16.00 hrs, or during the technical sessions where we will be presenting a paper on FLNG (Session # 040, Wednesday May 7, 14.00 hrs)
New grid generation tools
In 2012, MARIN started a comprehensive project to create new geometry tools for propellers and ship hulls. New tools were developed as Rhinoceros plug-ins for propeller CFD and model production. Recently, the focus has shifted to grid generation for ship hulls and offshore structures.
The latest developments allow the user to generate structured and unstructured grids with full control over grid density, grid line spacing and grid refinement. The discretised geometry can be exported in the desired formats for
RAPID, DIFFRAC, PARNASSOS, but also in other open formats like VTK. Geometry deformation has also been re-implemented in Rhinoceros to generate different hull shapes based on a combination of basic hull shapes. This enables even faster hull-variation studies necessary for trend analysis in the early hull-design stage.
This year, the existing MARIN hull lines design tool ‘Geometry Modelling of Ships’ (GMS) is being re-implemented. For more information contact Menno Deij-van Rijswijk, m.de
Maritime Industr May 13-15
MARIN will be present at the “Maritime Industry” (previously “Construction & Shipping Industry”) event held in Gorinchem, the Netherlands. Visit us at stand 325 to discuss the broad range of services we offer the inland shipping industry.
INEC May 20-22
12th International Naval Engineering Conference and Exhibition 2014
There is also a chance to meet us at the International Naval Engineering (INEC) Exhibition in Amsterdam or during the conference where MARIN will be presenting a paper in the Green Ship Session.
