About MarineStream
Franmarine has been developing in-water cleaning and biofouling management technology in Australia for decades. The subject matter expertise and technology-enabled capability is now accessible to the world.
Where MarineStream came from
Franmarine has delivered integrated biofouling management and underwater engineering out of Henderson, Western Australia since 1981. MarineStream started as the internal system that kept that work standardised and auditable. It is now available to vessel owners, fleet operators, facility managers, diving contractors, hull cleaners and ROV operators who need a system that works.
The people behind it are using it today to run the only commercial in-water cleaning operation in Australia.
Four steps that feed each other
Each service stands on its own and most of our customers start with one. They work better together, because a survey is only useful if someone can act on it, and a clean is only defensible if it was recorded. Partners who would rather do the work themselves can buy the same systems, software and training through sales.
Write the plan
Management plans written per vessel, and one condition based standard applied across a fleet.
Biofouling management → 02 · INSPECTFind out where it stands
ROV and diver surveys in the field, backed by a DPIRD-registered IMS inspector.
Biofouling inspection → 03 · CLEANAct on the finding
A range of in-water cleaning options that include capture and filtration where the port requires it.
Hull cleaning → 04 · PROVEKeep the record
Class survey and fleet-wide evidence accessible on one platform, so an audit pack is generated rather than assembled.
Fleet management →Four commitments
Standards aligned
Inspection, cleaning and records mapped to the IMO biofouling guidelines and in accordance with class rules.
Field proven
The technologies and capabilities we offer are proven on vessels, aquaculture, ports and marinas and offshore infrastructure before we sell them.
Audit ready
Ratings, evidence, approvals and reports all sit in one place per vessel.
Partner first
We would rather complement diving contractors and ROV teams than bid against them for every job.
What defence work taught us
Our people and systems work across defence, commercial and energy sectors, with more than 85 assets inspected and cleaned to standard. Our defence customers set the bar on objective quality evidence (OQE), and we adopted this as the baseline for the benefit of all others.
