Deepwater: Retrobuoy™ Junior


A single float version of Retrobuoy™, the Retrobuoy™ Junior is a modular impressed-current anode array rated at 150 Amperes for 20 years in its standard configuration.


The buoy’s three anodes are held within a buoyant module stabilised on the seafloor by a SeaMat gravity base.

Routing the ICCP system cable can be done in a variety of ways depending on project needs.

Mixed-metal-oxide-activated titanium electrodes allow the anode sled to be operated at a very high current output.

The FLXMAT base can be assembled locally in country to provide local content requirements.


Anode elements: Mixed metal oxide (MMO) activated titanium tubular 1.25 in x 48 in (31.75 x 1219 mm) – centre compression connected. Anodes triple coated. Each RetroBuoy MkIV has 4 buoyancy modules each containing 3 MMO tubes.

Buoyancy modules: PE injection moulded shell / vacuum filled syntactic foam 36 lb./ft.3 (576 kg/m3) – Depth rating 1000 f.s.w. (305 metres).

Four buoyancy modules provided per RetroBuoy MkIV. Overall dimensions: 12.75 in Ø x 60 in long (325 x 1524 mm).

Tethers : 1″ Plasma 12 strand synthetic rope.

Each Retrobuoy junior can output up to 200 amps of cathodic protection current, enough to protect 30,000 sq. ft of steel.
