What the fleet is built for

Power-plant intakesIntake canals and cooling-water pools where a 1.0 m draft gets in and a hopper cannot.
Port basins and jettiesBerth pockets and basins to −12 m LWS, including coal and mud sediment.
Rivers and reservoirsWet channels and reservoirs where bank excavators cannot reach the bed.
Sand winning and reclamationProduction charters pumping sand to shore up to 1,000 m away.

Two ways to engage

Time charter of a vessel with crew, service boat and floating pipe, or a unit-rate works contract per cubic metre. Rates are quoted per job.

Measured, not estimated

Independent bathymetry before and after each job, and daily logs countersigned on site, so the volume paid for is the volume moved.
