Feature 3 | CAD/CAM MasterShip joins forces with SARC
Te Netherlands-based MasterShip and SARC have decided to team up on future projects, improving the efficiency of the design process
T
he partnership between the companies will bring the two ends of the design and construction
process together. In a competitive environment, closing existing gaps and eliminating overlaps in the shipbuilding process are getting increasingly important, says MasterShip. SARC (design and stability soſtware) and
MasterShip (modelling and production software) will be cooperating closely, which will lead to a better workflow from concept design to construction modelling, production and loading evaluation. Jacques Hoffmans, a spokesman for MasterShip, says:
“Our cooperation is
an opportunity for one stop buying for our clients of two best‐in‐class and fully integrated software tools for design and work preparation, so avoiding gaps and overlaps.” Herbert Koelman from SARC added: “Tis partnership is also streamlining our international exposure and support.” Added to this is the launch of MasterShip’s
Workshop assistant, which will bring users a 3D model of the designs into the workshop. Aſter a two-year innovation programme, MasterShip has developed its latest soſtware and hardware solution. Te Workshop Assistant is a touch-screen table that brings the 3D ship model to the shop
floor. Te first tests done by two shipyards have shown good results, says MasterShip. It noted that building information was much easier to understand and provided welding, fitting and assembly information. MasterShip has also said that engineering cost decreased as the expense of the creation of production drawings went down. Furthermore, MasterShip has also
introduced its template oriented modelling (TOM) which, will give users an easy method in which to create parts using predefined ship construction templates. Parts made with TOM are updated when there are changes in the 3D lines plan or parameters. 3D construction models and 2D construction, class and workshop drawings can be created simultaneously, efficiently and faster. TOM allows the creation of construction
even when the exact location of the shell seams is not known. Users first create the part and, when the exact location is known, they can add the necessary welding hole and other details. Tis allows for more accurate weight and centre of gravity (COG) estimates early on in the process, says the company. TOM is implemented in both MasterShip’s
Modelling Software and Production Soſtware. Tis guarantees a standard work method and an easy link to the production
NAPA thinks outside the box
Finnish-based NAPA introduces its Box Transformation for hull definition and manipulation of surface areas
H 60
ull form outline makes for a natural first step towards eco-efficient design. However,
it is very difficult to find the optimal hull form by any manual method as it would take many hours work for the designer to run through every variable manually. Hence, the increasing demand for optimal hull forms to be developed using automated hull form modification and optimisation algorithms.
NAPA’s latest edition to its toolbox will
give the user a more efficient method for transforming hull forms, without affecting the fairness of the hull design. Traditionally, the hull line is developed by controlling the points of the definition curves of the hull surface and can take several hours to obtain a faired hull form even though the amount of required modifications can be small. NAPA’s
latest function, called Box Transformation handles not the points on the
curves, but the hull surface itself by controlling the control indices of the transformation box. Te time needed for modifying a hull form is dramatically decreased as it will only take minutes to obtain a transformed surface faired enough for the use, says NAPA. Te user can define a transformation
box that covers a part of the hull surface and modifies the box by moving the control points (by stretching or skewing, for instance). As a result, the part of the

phase resulting in time saving and better control of the process.
SARC updates SARC has presented the release of an interface of its Fairway hull design soſtware. Fairway allows full and direct control over actual hull lines by simple operations. Tereby, hull design per computer is made as flexible and versatile as draſting on paper. Te interface is developed to improve the user friendliness of Fairway. Different types of soſtware can now make use of the same basic geometry model of the vessel, which will reduce double input, data conversions, version conflicts, and so on. Beside the Fairway interface, SARC has
also launched its latest method to define the subdivision of a vessel, named Newlay. Newlay allows bulkheads to generate
defined compartments and vice versa. Either of these two types of models can be most suitable, depending on preferences and project composition. Tis development includes an open interface for communication with different types of dedicated soſtware such as MasterShip. Tis means that different types of soſtware
can now make use of the same basic geometry model of the vessel, which will reduce double input, data conversions and version conflicts, which will save the designer time. NA
