SUMMARY An overview of computational tools for the hydrodynamic design of fast ships is given. The individual techniques are discussed, and suitable tools are recommended. Trends are discussed and illustrated by some advanced pioneering applications.
Performing inspections for Hull Condition Monitoring and Assessment as stipulated in IACS unified requirements and IMO's Condition Assessment Scheme (CAS) [5], [6] involves a huge amount of measurement data to be collected, processed, analysed and maintained. Information to be recorded consists of thickness measurements and visual assessment of coa...
An overview of simulations for assorted advanced analyses for maritime structures is given. These structures include fixed and floating offshore structures as well as ships. The overview is intended to give an introduction to the multitude of simulation tools, seen from an industry perspective. The individual techniques are discussed, and suitable...
Corrosion is one of the major issues for the structural condition of a vessel during its service life. In case of tankers and bulk carriers this aspect is even more crucial due to the exposure of the structure not only to salt water, but also to other abrasive substances in the cargo spaces. In order to monitor the condition of structural component...
With GL.ShipLoad, Germanischer Lloyd provides a user friendly computer application for the efficient load generation for global FE analyses of ship structures. The graphical user interface facilitates the convenient application of ship and cargo masses to the FE model. Hydrostatic and hydrodynamic computations are integrated into the program. GL.Sh...

... CFD is a popular tool for evaluating new hull form design. By solving field equations that describes the dynamics of fluid flow, CFD is able to provide accurate simulation of fluid flow [24]. CFD have also been used to assess the performance of vessels in terms of propulsion, seakeeping, maneuvering and propeller designs [25]. ...
... The most used and economical end-of-life methods for disposing composite materials are still incineration and landfill deposition. Still these methods can cause great impact to the environment, mainly incineration for the toxic by-products that can be generated [1]. In this context, phenalkamines and phenalkamides feature a series of benefits that make themselves interesting as sustainable hardeners applied in the epoxy resin suitable for infusion process, highly used in boat production. ...
... The user-friendly software tool GL ShipLoad was developed to efficiently generate loads for a reliable and robust global FE analysis of containerships [3]. Based on the design wave approach, this software finds the most relevant load combinations to dimension the ship's structure. ...
... RBI on the other hand is complementary to RCM in terms of dealing with the structural reliability of structures, either ships or offshore ones. In order to accomplish this task, Jaramillo and Cabos (2006) developed a computer hull condition monitoring system which assists in the easier association of survey data with their location on board the ship. In Straub et al (2006) the RBI application is presented regarding fatigue deterioration for offshore fixed steel structures and floating, production, storage and offloading vessels (FPSO's). ...
... The results are computed and displayed for the regions of the ship selected in the tree view. Hull data can be exchanged in XML format in accordance with the HCM, developed to provide support for the hull condition assessment (Jaramillo and Cabos 2007 ), providing support for the planning, viewing and analysing the results from thickness measurement campaigns (Jaramillo et al. 2005). Therefore, although the user is able to export the entire ship, including structure definitions, using the GUI, the information is filtered internally and only the data that can be mapped into the HCM are exported. ...
... economical advantages via either minimize operating costs or maximizing the potential earnings during operational life. Some representative research results can be found: [9,[17][18][19][20][21][22][23]. The optimization process must take a holistic approach by suitably incorporating inputs from all the three main stake holders, e.g. ...
