Fleet · Floating access

Pontoons
& work platforms

Flat decks, modular systems and specialist platforms configured around access, plant, welfare and the workface.

Configured for the operation

The craft is the
starting point.

A floating platform can create working space where the bank cannot. WHH can configure deck area, edge protection, access, ballast, spud legs and plant around the task—from a small inspection platform to a stable base for machinery or site welfare.

Published dimensions and capacities are a guide. Final suitability, loading, stability and working configuration are confirmed against the site and intended operation.
