Charta Software Tailor-made software combined with professional hosting, maintenance and support. Founded in 2006, Rotterdam. Expert in combining complex (mathematical) techniques and computer science innovations. Various domains:
PROTIDE PRObabilistic TIdal window Determination: Determine transit (tidal) windows and itineraries for deep draft shipping based on keel clearance and ship motion analysis No minimum fixed keel clearance, but dynamic based on individual ship dimensions and up-to-date meteorological and hydrological forecasts Maximize the (harbor) accessibility for given safety criteria Probabilistic: safe keel clearance = probability of not touching channel bottom Increased safety in rough conditions Increased accessibility in calm conditions Graphical insight in calculation and results
PROTIDE Transit windows Windows of opportunity

Ship motion OCTOPUS (by Amarcon ABB) Database of hull shapes: Tanker Bulk carrier Container Car carrier … Scaling of selected hull to given ship dimensions (length, beam, DWT) to create an individual hull. Calculate the RAO based on hull, draft, trim, displacement, free fluids surface correction. Calculate 6 point response on sea state per h/T, speed, heading.

Evaluation: ship motion Measure actual ship movements with speed/course in transits. Registered movements are translated to roll, pitch and vertical motion on virtual points. Sensor is certified for error of 0.02 to 0.03 degrees roll/pitch and 5cm heave <15cm error margin in the extremes of the ship.
Evaluation: ship motion Measured compared to modelled vertical motion Actual roll and pitch compared to expected Actual vertical motion compared to expected
