SargaJet® and SargaMap: up to 50% lower sargassum collection costs*
SargaJet® is a patented offshore collection system designed to collect large volumes quickly at low cost. It can work with SargaMap to locate sargassum and forecast where it may strand in a given area. SargaMap further reduces logistics costs through earlier, proportionate deployment of collection resources.

The problem
Strandings are expensive because they are treated too late
Once stranded, sargassum is more difficult to remove, often mixed with sand, and requires repeated interventions on the beach. For hotels, local authorities and operators, this means high costs, emergency response and a degraded visitor experience and coastline.
Degraded coastline
Nuisance for users, image of the site affected, sand collected during beach collections.
Reactive operations
Interventions often decided urgently, depending on the arrival of sargassum.
What SargaJet® changes
Collect at sea, before stranding
The SargaJet® is designed to capture sargassum before it runs aground, increase the available volumes and significantly reduce the cost per tonne collected.
SargaMap locates aggregations
Sargassum patches at sea are identified and monitored.
The boat tows the SargaJet®
A standard boat tows the structure towards the sargassum mats.
The nets fill continuously and automatically
Collection happens while moving, at high volume, without constant intervention on each net.
The full nets are then recovered
The biomass is brought ashore for handling or processing.
For whom?
A solution for those who manage strandings
01
Beachfront hotels and resorts
Reduce collection costs, preserve the customer experience and limit heavy interventions on the beach.
02
Coastal local authorities
Manage a beach area with a solution that can be shared, mobile and compatible with a circular valorization logic.
03
Beach management organisations
Protect a site while limiting damage to the beach, the passage of heavy machinery and the removal of sand.
04
Collection operators
Increase collection capacity, reduce marginal cost and offer a more competitive service.

Performance depends on the configuration, the density of the slicks, the state of the sea, the local organization and the current collection method. The personalized estimate makes it possible to specify the real potential site by site.
SargaMap + SargaJet®
Anticipate arrivals, then act in the right place
SargaMap helps to locate aggregations of sargassum at sea and to better organize interventions. Combined with SargaJet®, it allows you to move from reactive management to more controlled management.

Built for the terrain
A low‑tech, robust and mobile system
01
No dedicated engine
Towed by the boat, without its own engine.
02
No onboard electronics
No sensitive parts on board the structure.
03
Lightweight, mobile and quick to deploy
Transportable from one site to another by road with a simple van, or from one coastal area to another at more than 10 knots.
04
Reusable and reloadable nets
Designed for multiple collection cycles, with reloading possible at sea when all nets have been used.
05
Portable by two people
Two people are enough to simplify launch, recovery and short moves.
06
Reduced environmental footprint
Recyclable, reconditionable or suitable for reuse within a circular economy depending on the components, SargaJet® generates less CO2 per tonne collected than mechanized offshore collection systems or artisanal side-scoop methods.
SargaJet®'s low‑tech design limits sensitive parts, simplifies use, reduces maintenance constraints and supports lean field operations.
FAQ
Frequently asked questions
The SargaJet® intervenes upstream, at sea, before stranding. It can complement existing systems and reduce the need for heavy interventions on the beach.
The SargaJet® is designed to be towed by a standard boat adapted to the intervention area.
Depending on the configuration, the SargaJet® can collect between 60 and 360 m³ of fresh sargassum per day, the equivalent of 10 to 60 drained tonnes.
SargaMap is included with the SargaJet®. It is also accessible separately, by subscription, for organisations that first wish to improve their anticipation.
Savings depend on your current method, volumes, stranding frequency, local organization and recommended configuration.
The SargaJet® is offered as an annual leasing model. The equipment remains the property of Sargawatt, with training and support included.
