What is a Hoverbarge?
Cargo Deck
Air Lift Fans
Buoyant Steel Structure
Air Cushion
A standard steel barge, built to marine rules with an air cushion system
to provide lift.
Hovering 1.8m in the air, the Hoverbarge is amphibious enabling it to
traverse, wetlands & mudflats etc.

Hovercraft v Hoverbarge
Hovercraft reach a speed where the skirt lifts out of the water (over hump) and then hover just
above the water surface.
The Hoverbarge travelling a slower speed of 5 knots will always remain under hump speed with
the tip of the skirts in the water. This results in less spray than high speed Hovercraft.
High speed Hovercraft
Over hump speed =
skirts clear of water surface

Air is fed into the skirt plenum chamber and
the skirt creates a flexible seal around the
periphery of the barge

Hoverbarge Advantages
Minimal Environmental Footprint
The Hoverbarge only exerts 1psi ground pressure when on hover, compared to a human footprint
of 7-8psi, thus the Hoverbarge has minimal impact to the terrain it travels over.
Large Flat top deck
The Hoverbarge has a large cargo deck, clear of any equipment, along with being flat top
(rather than in a well deck) the Hoverbarge provides huge flexibility in the type of operations
it can be deployed on.

Hoverbarge Advantages
Redundancy
In soft mud / water conditions, the Hoverbarge has 100% redundancy built into its lift fan
capacity, ensuring minimal disruption to operations in the event of an engine failure.
Engine Enclosures
Engine enclosures are designed to ensure the engine, fuel tank and lift fans are protected
from extreme temperature. The housing also reduces sound levels and shore power can
supply heaters in the enclosures whilst the craft is not in service.

11
Hoverbarge Advantages
Skirt System
The segmented skirt system provides added redundancy, where if a segment is damaged the
one either side balloons out to fill the gap, minimising any air loss. Replacement of damaged
skirts can be done on site and does not require special skills or tools
Missing skirt segment – the
one each side fills the gap
Skirt following contours of the ground
Skirt R&D – Hovertrans Solutions is constantly improving designs for different applications

Modular Hoverbarge
 Reduced Shipping Costs
 Access to inland areas via trucks
 Easy to use on different projects
 Use the pontoons as standard
marine pontoons
 Steel Construction
 Easy to assemble on site
The first Modular Hoverbarge was
invented by the CTO of Hovertrans
Solutions in the 1970’s.

Mono Hull Hoverbarge
• Increased payload
• Can be built on-site
• Ideal for long term contracts
• Built to certification

Launching the Hoverbarge
Once built or re-assembled the Hoverbarge
can be launched direct from a beach or
graded river bank.

15
Large Payloads
• Best application for air cushion
technology
• Moving a 250 ton oil storage tank
soon led to a 4000 ton tank being
relocated
• The Sea Pearl could lift the cross
channel Hovercraft on its back
• Larger deck area = higher payload
© Hovertrans Solutions Pte. Ltd. 2014
16
Size & Cost
• For a small increase in size with little
extra power, the payload increases
significantly
Cost
• As the Hoverbarge size increases, the
cost increases in steps
