Slide 1Operate in a coordinated manner
Combat a variety of oil-spills in a
multitude of marine environments
2006 EU-MOP Consortium
engineering task:
a pre-specified task; The units comprising the
system are complex devices with specifications
that are part of the design effort.
System Level
search-and-follow the slick
System/swarm level
Power: 10-50kW, Length: 3m, Brush, Propulsion: electric motors with propellers or water jets
2006 EU-MOP Consortium
Propulsion 2 x Azimuthing thrusters
Trim adjustment No ballasts
Effect of Speed
2006 EU-MOP Consortium
Multi-monocat integrated design
2006 EU-MOP Consortium
Propulsion 2 x Azimuthing thrusters
Trim adjustment 2x 125l water ballasts
Anti capzising volume (mast)
Design of monocat EU-MOP
Lightship 1735 13.2 0.45
Hull Design features:
- Provides enough volume for oil storage and equipment fitting.
- Minimize drag.
- Minimised change in draft with increasing loading.
- Centre of volume located slightly aft for minimizing trim with increasing loading.
Design of monocat EU-MOP
Fore hull clearance 0.7 m
Air draft 2.13 m
1.4 m3 oil tank
Trim adjustment 2x 90l water ballasts
Anti capzising volume (mast)
Design of monocat EU-MOP
surf (m²)
Hull Design features:
Parametric scaling from Large unit’s Hull with specific targets:
-Length constrained by 40’ container size
-Increased freeboard / Length ratio
-Increased Breadth / Length ratio
Design of monocat EU-MOP
2006 EU-MOP Consortium
Upper bounds of units’ allocations; storage of equipment at facility i only if it is opened
Total capacity sent to each spill not more than its volume multiplied by the desired coverage coefficient
The objective function:
Strategic level
Vo = 120 m3, T = 13oC, Wind speed = 20 Kn
Simulations: Natural Weathering
2006 EU-MOP Consortium
11 hrs EU-MOP operation
*The AI and unit coordination aspect of the Project
is of paramount importance
technical specifics of the docking and unloading
modules are emerging as major challenges
