Requirements (Examples):
- Which technical services?
- What service level in which area? - What service quality parameters?
The future Maritime Service Portfolios (MSPs) of the NSR: Service “Spectra”
Power of the services spectra concept:
All services (existing + new) identified, named and thereby recognized in an internationally harmonized manner => catalogues of services.
Service levels, service quality parameters (existing + new) equally identified, named and thereby recognized in internationally harmonized manner
=> catalogue of service levels + service parameters.
Such catalogues may be transferred into a data model (product specification within S-100 framework) at CMDS => electronic exchange feasible and
measurement of service spectra at run time.
Service-to-service dependencies (= requirements) would be known exactly
=> applicability of requirement management methods.
International, harmonized role assignment for maintaining service descriptions by clearly identified international organisations feasible.
Reduction of complexity regarding MSP handling.
Synergies for (at least technical) services could potentially be gained by using same service levels + service parameters for several requirements.

Coverage Areas Mari ti me Se rvice Portfol ios (M SP s) / Se rvice S pe ctrum
The future Maritime Service Portfolios (MSPs) of the NSR: Where-to apply?
Two principal options for service provision:
- Blanket coverage irrespective of traffic
“coverage area”
service provision within coverage area
correlation between MSPs and areas - Traffic sensitive coverage
service provision at routes
“Route Topology Model (RTM)”
What is a Route Topology Model?
Junction
Leg Node, e.g. Port The construction of Route Topology Models using
three elements:
Attributes attached to each element:
- physical attributes: location, width, length, …
- traffic related attributes: direction, density, …
- services provided => Maritime Service Portfolio - …
Modeled using IHO S-100 methodology:
“RTM Product Specification”: “Features”, “Portrayal”

Potential applications of the NSR-RTM
(Generic) Route Topology Modeling is a description tool: - Captures a present situation, as derived from traffic
density analysis and objective features of waterways and ports
- Allows for higher level analysis: add attributes
Example: IWRAP risk figures modeled as attributes in the RTM.
- Allows to capture present service spectra in correlation with routes, junctions, nodes.
- Allows to categorize different levels of waterways and sea routes
Potential applications of the NSR-RTM An initial IWRAP risk analysis as based on the NSR-RTM IWRAP risk values entered as attributes
Potential applications of the NSR-RTM Three potential levels of the NSR-RTM: 1. Motorways of the Sea (MoS) shipping lanes
2. Roads of the Sea (RoS) shipping lanes, i. e. shipping lanes, other than MoS, relevant
for professional/commercial shipping (including ferry routes, offshore construction and supply traffic etc.);
3. Small Craft (SC) shipping lanes, i. e. all other shipping lanes, in particular those only
available, due to physical dimensions, for small crafts such as fishing vessels and pleasure crafts.

Potential applications of the NSR-RTM
(Generic) Route Topology Modeling is a planning tool: - Captures a perceived future situation, as based on traffic
forecasts and planned objective features of waterways and ports
- Allows for higher level analysis: add attributes on future
Example: IWRAP risk figures modeled as attributes in the RTM on perceived future
situation (2020+).
- Allows to capture future planned/required service
spectrum, i. e. future Maritime Service Portfolio(s).
- Allows to create a development plan for different levels of waterways and sea routes => fill the TEN MoS “gaps” - May reconcile shipping needs with Marine Spatial
Planning: a well justified grid of future Traffic Separation Schemes in North Sea Region as a proposal for IMO?
Next steps with ACCSEAS
- Further develop generic description of the Route Topology Model:
- Verbal / graphical description in comprehensive standalone document
- Start develop IHO S-100 based “product specification”, “features”,
“portrayal”
- Offer to international e-Navigation movement for standardization on global scale => generic global MSPs; contribution to CMDS (HGDM)
- Create initial North Sea Region Route Topology Model (NSR-RTM)
for present situation and future situation (2020+)
- Create NSR-Maritime Service Portfolios (MSPs) map (following
Canadian example): associate existing service spectra/MSPs to routes where meaningful.
