4×4 Horseshoe

Pile horseshoe – 360° access for cutting, wrapping, blasting & painting

The 4mx4m pontoon is shown here as a customised pile pontoon, made in a horseshoe shape with a pile recess. The addition of a drop-in deck section then gives full ‘walk around’ 360° access. Podium steps or a Monkey Tower give access from the waterline to +4.5m which gives a significant tidal working window for cutting, blasting, wrapping, painting and fitting anodes. This same recess can be fitted to any size ScaffFloat.

Access: Podium Steps, Monkey Tower

Specification

Note: Above are indicative guidelines. Specific limits will be set for each project based on operating environment, load type, activity and the RAMS for that project.

Propulsion

These ScaffFloats can be moved easily with a small workboat, or we can make them self propelled with an outboard pod. Alternatively we can supply one of our 8×4 workboat ScaffFloats to push the horseshoe pontoon into position.

Certification & Compliance

As standard, all our pontoons come with a stability board produced by our Naval Architect, TG20 compliant edge protection and MGN469 compliant safety equipment.
We also supply a specific load assessment and limits for the planned scope of works and additional certifications when necessary or requested:

• Structural calculations
• MCA Compliance
• LOLER checks and inspections
• Eurocode and British Standards assessments and certifications
• Category III scaffolding design certification
• PLA Licensing

Our floats are available only for hire, and we are very strict about this, even though people constantly ask if they can buy the floats. We do this to maintain control over how the system is used. We make sure that every project has a proper design and stability assessment, and that we have overseen or checked the RAMS. Safety is one of the things our customers like most about ScaffFloat. Therefore, it is vital that we maintain our track record, and to do this we need to retain some control.

In terms of regulations, we operate under a range of frameworks

The marine side: We work within the frameworks of several regulatory bodies which cover manning, safety equipment, stability standards and minimum freeboards

• MCA (the Maritime and Coastguard Agency UK)
• PLA (the Port of London Authority),
• IMO (the International Maritime Organization)

Scaffolding Regulations: Most of TG20:13 and other scaffold regulations are not relevant to what we do, but we do use elements of it for things like edge protection.

Lifting:

• Lloyd’s Register Code for Lifting Appliances in a Marine Environment
• LOLER: All our cranes are tested according to LOLER (Lifting Operations and Lifting Equipment Regulations UK)

Structural Design: If the project requires it, we use the below frameworks to assess structure. On larger projects we can also offer customers an independent Cat 3 check by our partner Richter; this gives our customers reassurance that we have taken a safe and prudent approach to our design and planned method of works.

• EuroCode EN1993-1-1-2005
• DNVGL-T-0378
• BS5975:2019 for temporary works
