MARLIN

Objectives

MARLIN provides:

  • a means for regulators and certification bodies to effectively and efficiently monitor responsible fishing at scale,
  • a solution for fishermen seeking to simply and efficiently report fishing activity to regulators.

Challenges

The following challenges could affect MARLIN’s technical success or end users’ adoption of the MARLIN system:

  • Availability of cellular 5G terrestrial network coverage in coastal regions
  • Complications integrating the MARLN sub-assembly with legacy Insight360 hardware
  • Electronic component availability
  • Ingress protection failing to achieve the necessary level of protection for marine environments
  • Incompatibility with existing legal constraints on data management and/or on-vessel hardware installation
  • Legislation does not mandate electronic monitoring of fishing vessels.

System Architecture

MARLIN’s on-vessel hardware is a sub-assembly to the underlying architecture of Arribada’s current Insight360 monitoring system, which autonomously records video and audio data. The MARLIN sub-assembly adds a range of cellular 5G modems and satellite Machine-to-Machine (M2M) transmitters and develops the software subsystems to drive and manage data transfer, exploring intelligent switching and optimisation of our hybrid comms solution.

The current design of the on-vessel hardware includes a waterproof IP68 enclosure, power regulation, Power-over-Ethernet (PoE), USB3, HDMI, mPCIe storage, hybrid cellular 5G and satellite M2M connectivity, Global Navigation Satellite System (GNSS), a 4 channel directional microphone for audio capture, IP CCTV cameras and an LCD diagnostic screen.

Plan

The MARLIN project spans ESA’s Definition and Technology Phases with four milestones.

Definition Phase

Purpose: Gather user requirements, define the system architecture, investigate compliance constraints, and create a product business model.

  • Milestone 1: Systems Requirements Review

Technology Phase

Purpose: Build and perform on-vessel tests of the MARLIN prototype hardware, build and test the dashboard software, and assess user experiences.

  • Milestone 2: Mid-term Review
  • Milestone 3: Preliminary Design Review
  • Milestone 4: Critical Design Review

Current Status

The MARLIN project began on December 2, 2024. The following covers work in February 2025.

Work in progress:

  • Interviewing stakeholders to understand what MARLIN will require to be successful for different end-user groups
  • Analysing the responses from stakeholder interviews
  • Creating a business plan centred on conducting market research, identifying key trends, estimating market size, and analysing competitors
  • Created an initial MARLIN hardware block diagram
  • Began testing software platforms for MARLIN

Next activities:

  • We will continue to do all of the above activities for the next two months
