Context
Nantes Saint-Nazaire Port is France's fourth largest seaport and the manager of a very diverse estate — quays, locks, port equipment, buildings and dredging plant — which the port itself counts in more than 750 structures, spread across three domains: port infrastructure, land infrastructure and buildings. The port already held a solid working knowledge of that estate, carried by the maintenance management systems in place and by the experience of its own staff. It set itself the objective of putting decisions on a more rational footing and of establishing its medium and long-term needs objectively, so that it could be confident it was carrying out the right actions at the right time. In practice that meant being able to steer maintenance and renewal on facts, and to reconcile budget optimisation with risk management, quality of service and the performance of the estate.
Our solution
- 01 Collect and structure Gather and structure the port's asset data across three domains: port infrastructure, land infrastructure and buildings.
- 02 Map condition and risk Digitise the estate in Simeo and map the state of wear of the assets together with the level of risk they carry.
- 03 Prioritise the data work itself Target the effort of making asset knowledge reliable where it actually changes a decision, rather than spreading it evenly across the whole estate.
- 04 Compare strategies as scenarios Evaluate what holding the estate in condition requires in investment, and where the priorities fall when means are constrained.
What Oxand delivered
Consolidated knowledge of the estate
One consolidated view that makes the condition of the estate and the risks attached to it legible across all three asset domains.
Indicators that communicate
Objective, shareable indicators that let technical teams and decision-makers prioritise and arbitrate on the same basis.
A multi-year plan that stays alive
A dynamic multi-year investment plan that can be re-run when a constraint changes, so medium and long-term decisions keep an objective basis.
The right action at the right time
The ability to steer maintenance and renewal on facts, reconciling budget optimisation with risk management, quality of service and asset performance.
Questions about this reference
What estate does Nantes Saint-Nazaire Port manage?
The port counts more than 750 structures in its estate, spread along 65 km of the Loire estuary and ranging from quays and locks to port equipment, buildings and dredging plant. More than 3 million m² of that estate is digitised in Simeo, across port infrastructure, land infrastructure and buildings.
What did Nantes Saint-Nazaire Port set out to do?
To put its asset decisions on a more rational footing and establish its medium and long-term needs objectively, so it could be confident it was carrying out the right actions at the right time. The port wanted to steer maintenance and renewal on facts, and to reconcile budget optimisation with risk management, quality of service and the performance of the estate.
Which asset domains were digitised in Simeo?
Three: port infrastructure, land infrastructure and buildings. Holding all three in a single reference is what allows the port to compare needs and priorities across an estate that runs from quays and locks to buildings and dredging plant.
What do the maintenance scenarios compare?
What holding the estate in condition requires in investment, and where the investment priorities fall when means are constrained — so the trade-off between the two is explicit rather than implicit.
What makes the multi-year investment plan dynamic?
The PPI is held as a model rather than written as a report. When a budget or an objective changes, the scenario is re-run and the consequence is visible, which is what keeps medium and long-term decisions on an objective basis.
