Scope of Supply


MODCAT's are available directly, either from our marine yard, or through an appointed distribution agent.


The following is an indicator of what is provided, and how these components are made available.


  • You may elect a full purpose designed platform, or opt for a Deck level package, and have the unit fitted out personally by your local propulsion and service provider.
  • We have established platforms such as the SML 1200 which have been specifically designed as a bespoke package for the Oil and Gas sector of the market.


Please familiarize yourself with our standard options as these can be tailored into the most cost efficient solution suitable for your specific requirements, and budget.




Our sales team will gladly provide you with a solution cost based on your selection.

These costs cover a fully constructed platform manufactured up to deck level which includes the following:


  • Each Sponson has 4 watertight compartments, each filled with an independent bilge pump system and is supplied as a modular unit, complete with fuel storage, anchor hatches, Sponson compartment access fitments, and motor out-mounts.
  • Integrated motor out-mounts are fully weld and fabricated from 6 mm aluminium plate, ensuring a robust mounting point for the clients proposed outboard engines.
  • Internal engine mounted modules are provided with adequate engine bearers, and reinforcement to accommodate this option, Jet or Propeller are also catered for. 

Deck support platform

  • The supplied deck and lattice beam sections, when assembled, are bolted together, and the complete deck support assembly unit is then secured to the Sponsons, creating a rigid and robust platform ready for deck equipment and superstructure installation.
  • Hard points are added to both the Sponson and deck modules to accommodate our client’s equipment, and operational layout requirements.
  • These deck platforms are constructed from heavy duty rectangular tubing, and are split into sections ensuring each section is easily transportable, and assembled when on site.
  • The standard MODCAT deck plates are fabricated from 4.5mm Marine Grade Aluminium tread plate, with pre-drilled rivet holes ready for attachment to the deck support structure when ready for assembly.
