Abstract
This paper presents the hull-to-hull (H2H) project where the concept of hull to hull positioning and uncertainty zones
are used to assist navigators and operators to perform safe navigation of objects in proximity to each other. Data from
position sensors and geometry (2D/3D) data will be shared amongst the H2H objects to calculate for example hull to
hull distance to help avoiding physical contact (e.g. steel-to-steel contact). H2H will utilize a variety of positioning
sensors, including the European GNSS systems Galileo and EGNOS. The H2H project aims to develop open interfaces
such that any H2H compliant equipment provider or user can use the services provided in the planned standard. Data
exchange protocols will be based on existing standards as the IHO S-100 standard for geometry and zone descriptions
and for describing additional layers needed for ECDIS. Finally, a working methodology describing the needed steps
from use case descriptions to implementation of the necessary services is presented.
