How do you protect against fouling on the Fiobuoy’s release?

The Fiobuoy’s patented release mechanism is designed in a way to ensure fouling does not affect its release. Many acoustic releases are designed with a mechanical arm, so when they are opened debris and seaweed etc can get caught on the arm preventing the line to be released. The Fiobuoy was designed with a jaw and ball-pin, not an arm. This means that when the release is actuated the jaw opens, releasing the pin and pushing any growth away.

However, if you are deploying in areas where high amounts of growth is expected, for instance in shallow or warm waters, you may need to consider marine growth on the rope spool. To prevent this Fiomarine recommends, and can supply, an application of an antifouling agent on the outer layer of rope.

Is the Fiobuoy difficult to maintain and service?

The Fiobuoy requires only minimal and simple maintenance, which can be carried out by the user. Depending on its use, the Fiobuoys Battery Pack need only be changed every 3-6 months for the acoustic models, and 12 months for the Time/Date. Currently the battery packs use high quality alkaline cells with standard battery pack construction. Fiomarine can supply packs, or provide technical details for local construction by qualified agents.

At the time of battery replacement the Fiobuoy’s o-rings can also be replaced, and your Fiobuoy is ready for deployment again. A Maintenance Kit includes everything you need. O-ring replacement is typically recommended every 12-24 months depending on inspection.

How can I be sure the Fiobuoy will surface in high currents?

In the ocean all bodies are affected by high currents but the unique dynamics and design of the Fiobuoy means it works differently to normal floats and acoustic releases.

Provided your Fiobuoy has an excess of rope for your deployment depth, your Fiobuoy will surface. Once surfaced, for the period of time it takes for the remaining line to unwind from the spool, you have time to retrieve it. This is because during this time the Fiobuoy is effectively an untethered free-floating body which will not be dragged under by currents (unless they are extremely strong).

Also the Fiobuoy’s unique ‘unwinding’ principle means it doesn’t need to drag or pull the full length of line through the water column. This combined with the fact that at the time of ‘unwinding’ the Fiobuoy doesn’t lift anything but its own weight means it rises to the surface easily.

Am I limited in the type and length of rope I can use?

The design of the Fiobuoy makes it easy to customise the rope for your specific deployment needs. Our TD100 & AC100 models, which are rated to 100 metres, can accommodate a maximum of 120m of rope. While our TD200 & AC200 models can fit a maximum of 250m all using 10mm diameter rope. Of course if you use a thinner rope you will fit more on. Because each Fiobuoy is made to order you can choose the length and strength of rope you need. We supply two types: 10mm Aquatec with a breaking strain of 1,300kg and 10mm Dyneema with a breaking strain of 5,000kg. Provided it is neutrally buoyant, our customers can also supply their own rope.

Is the Fiobuoy protected against rope entanglement?

The Fiobuoy is designed specifically to combat rope entanglement. Its design replicates the method rope manufacturers use to supply rope; the simplest and most effective way – on a spool. Rope released from a canister can get easily tangled, whereas the Fiobuoy unwinds naturally, and our Winders make for simple and fast re-deployment.
