Mooring Options

Driven Piles – The features of this type of a restraint system are:
Reduced sway movement of floating infrastructure; resulting in an improved fatigue life for joints
Small overall marina footprint
Piles can be external or internal in the floating infrastructure
Reduced maintenance of floating infrastructure compared to mooring systems

Quay Wall Piles –The features of this type of a restraint system are:
Similar to the driven piles there is reduced sway movement of floating breakwater infrastructure; resulting in an improved fatigue life for joints
Small overall marina footprint
Piles can be bolted to a concrete/stone quay wall or welded to a sheet pile quay wall
More cost effective piling option than driven piles
Only suitable for pontoons, breakwaters are not normally restrained in this manner
H Piles can be galvanised and/or painted for longevity
Reduced maintenance of floating infrastructure compared to mooring systems

Mooring Arms – The features of this type of restraint system are:

Suitable where piles are not an option and there is limited footprint for a mooring system
Arms are fabricated from galvanised steel for longevity
Arms are hinged for the range of vertical motions
Joints and Arms are designed by ICMS for the environmental and berthing loads
Mooring Arms can also be used as access gangways
MP to provide photo of restraining arms.

Chain Mooring SystemThe features of this type of restraint system are:

  • Weight of Chain in the catenary counteracts the environmental and berthing loads
  • Chain can be held in place by gravity anchors or plough anchors
  • Requires a large footprint
  • The forces acting on the system are lower than a piled system as the pontoons can sway when impacted with loads
  • Can be a large range of motions
  • ICMS can provide a full mooring system design compliant with BS6349:Part 6


Elastomeric/Rubberised Mooring System
The features of this type of restraint system are:

  • Tensioned mooring system – rubber in the system extends when loads are applied
  • A reduced footprint is required compared to a chain mooring system
  • As the moorings are tensioned the range of motions are reduced compared to a chain mooring system

Rope Mooring System The features of this type of restraint system are:

  • Similar to a rubberised system this is also a tensioned system whereby the rope extends when a load is applied
  • Ropes have to be installed at very shallow angles to achieve the required extensions; therefore, a large footprint is required
  • Excellent solution where high environmental loadings are likely to be incurred
  • Requires design by specialist engineers
