ARC

The original Acoustic Release Rope Canister, meticulously proven on over a thousand successful deployments since 2017.

The ARC acoustic release canister retrieval system is designed specifically for use with Innovasea VR2AR fish tracking acoustic release (AR) receiver and the Ascent AR. When the AR is activated the ARC brings it to the surface whilst leaving a rope attached to the anchor for easy recovery of all seabed mooring infrastructure. Additional sensors such as PAM acoustic recorders, CTDs and cameras can be mounted to and recovered using the ARC system. The system is low-cost and easy to maintain and includes lifetime product support from RS Aqua.

Key Features

  • Compatible with world-leading Innovasea Acoustic Release
  • Allows simple recovery of seabed mooring
  • Proven across hundreds of deployments
  • Buoyancy: 3 x 11″ trawl floats; widely available off the shelf

There are 3 depth ratings available for the ARC:

  1. The ARC – 150 m rope capacity
  2. The BARC (Big ARC) – 300 m rope capacity
  3. The LARC (Long ARC) – 450 m rope capacity

The ARC X is made with a 6mm longer canister to accommodate the larger receiver housing of the VR2AR-X

The ARC system comprises two main sections; the upper plate and the rope canister.

Upper Plate

The upper plate attaches to the VR2AR mooring brackets and holds three 11” 8.4 kg buoyancy trawl floats. This section ascends to the surface when the VR2AR acoustic release is activated. One end of the rope (coiled inside the rope canister) is also attached to the upper plate.

Rope Canister

The rope canister is attached to the release lug at the base of the VR2AR and the seabed anchor. Each standard canister holds up to 150 m x 4mm Dyneema rope or 65 m x 8mm Poly Prop rope with larger canisters available if required. As the upper plate ascends, the rope is spooled out of the canister allowing subsequent recovery of the seabed anchor.

Construction

The ARC system is built with robust, high-quality materials, no moving parts and minimal fittings. This reduces failure points, and minimises maintenance, whilst keeping total costs low. It is designed to present a low profile in high tide and current environments, and all parts can be removed for easy replacement and cost-effective shipping.

A covert version of the ARC – the Defence ARC – features a more streamlined squared float, making it ideally suited for RIB-based deployments.

ARC LEG MATERIAL COMPARISON

Stainless Steel

Delrin Plastic

Higher durability, less likely to get damaged in transportation, deployment, and recovery.

Better for longer term deployments as less corrosive

Extra node prevents some corrosion (not completely)
