Work Barges & Maintenance Platforms

Work barges and maintenance platforms for marinas, contractors and sheltered water

From the Westhaven pile-servicing barge to a cargo barge in Tonga that moved horses off an island after the tsunami. Rugged, modular, sized to the job.

What A Work Barge Looks Like

A hull you can size to the load, and grow when the job does

Two or three hulls of Main Boat Pods, a steel or timber deck frame, and whatever the job needs on top: a crane, a digger, a pump, a workshop. Each Main Boat Pod carries 150kg at half immersion and up to 350kg fully immersed.

  • No antifoul and no fuel in the floats
  • Add pods for a heavier job, take them off for the next one
  • Pods ship by container and assemble on site
Which Pods And Why

Main Boat Pods in two or three hulls

Main Boat Pods carry the most per pod and bolt into hulls of any length. Bow Pods on the front of each hull if the barge is motorised. Raft Pods suit light, static platforms.

Work Barge FAQs

Questions from contractors and operators

How much can a work barge carry?

Each Main Boat Pod carries 150kg at half immersion and up to 350kg fully immersed. A 26-pod platform carries a 6-tonne pump. Send us the load and we'll size the hulls.

Does a commercial barge need survey?

If it operates commercially it may need survey with Maritime NZ, or AMSA in Australia. We supply pod specifications and load ratings to your surveyor.

Can I make it bigger later?

Yes. Add pods to lengthen a hull or add a hull for more width and load. The same tie-off points take the extra pods.

How is it delivered?

Pods ship from Auckland to your address or nearest port anywhere in New Zealand, Australia and the Pacific. A container holds 50 Main Pods and 12 Bow Pods.
