8m x 4m

Our most popular ScaffFloat size – a versatile work boat

This 8m x 4m is by far the most popular size that we send out on hire. It has a useful 4t payload and with twin high thrust outboards can be used as a multifunction work boat on-site moving materials, doing crew transfers, push towing other pontoons around, helping position other barges and jack-ups and giving access up to 8m from the water with podium steps, Monkey Tower, scaffold tower or our 9m MEWP.

Access: Podium Steps, Monkey Tower, Scaffold Tower, MEWP

Mooring options: Windlass

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

Powered by twin 60hp high thrust outboards giving 0.8t of bollard pull. Independent fuel and electrics give redundancy and safety in tidal waters. Used as a general workboat, mobile access platform or for towing, normally in a push tow configuration.

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.
