    IUU and Fisheries Crime at landing

    • For IUU and fisheries crime the point of landing is critical

    • The North-East Atlantic situation • Weighing systems can be manipulated

    – RSW landings (up to 70 tones per hour) – Mackerel the most valuable specie

    • First hand value per hour in 2015 – USD approx. 68.500 – EUR approx. 60.500 – NZD approx. 103.000

    MCS of pelagic fisheries in North-East Atlantic

    • Regulated by Costal State Agreements – Cooperation between Costal States in the

    field of MCS – Working Group of Control Experts

    • Tasked to focus on issues that can effect quota outtake and the objective of a level playing field

    • Manipulation of weighing instruments identified as a serious challenge

  • Marine life – our common responsibility www.fiskeridir.no

    International recommendations

    • International Organisation of Legal Metrology (OIML) - Located in Paris, France – 128 members (UN 193) – The aim of OIML is to enhance the impact of industrial

    development and economic growth and to minimize technical barriers to trade

    • Norway have identified gaps between international recommendations for belt weighing systems and what is needed to enforce fisheries laws and regulations – Norway have adjusted national regulations to fill these

    gaps

  • Marine life – our common responsibility www.fiskeridir.no

    Weighing systems in use incl. PLC systems

    • Type of weighing systems in use;

    – human consumption: belt weighing systems – industrial purposes (fishmeal/fish oil): batch

    weighing systems • Programmable Logic Controller (PLC) systems are

    usually connected to such weighing systems • Weighing systems connected to PLC systems are

    challenging from a law and enforcement point of view

    PLC systems What is it???

    • Industrial computer control systems – Mission to steer processing functions based on

    signals from various sources – Production lines, machine functions or process

    could be customized and enhanced using PLC – Commonly used in all industries

    • Benefits using PLC systems: – the ability to change and replicate the operation or

    process while collecting and communicating vital information

    – it is modular and can mix and match types of “input/output” devices

  • Marine life – our common responsibility www.fiskeridir.no

    PLC systems What is it??

    • “Open system” (no sealing) – It is easy/possible to:

    • access the system • change parameters and functions in PLC software • change or bypass weighing functions

    • Result: Manipulation of weighing instruments

    carried out by remote control of the PLC system using smartphones, tablets or PC

    Type of manipulations

    • Manipulation of weighing systems could de done: – Mechanical – Electronical – Breaking seals – Through PLC systems “bypass” seals in or at

    weighing systems

    Examples of manipulating belt weighing systems

    • Preventing “free movement” of the weighing bridge – Ex: Wooden wedges, piece of plastic, broomstick

    • Interfering with Zero-point settings

    – Setting new “negative” zero–tare with load on

    • Disconnecting the belt weighing systems “stop function” – The belt weighing system can run without any register

    of fish passing the weighing bridge (used as ordinary conveyer belt)

    Consequences of manipulating the weighing systems

    • Weighing systems are used to “laundry” fish – The registered quantities are less than the

    quantities that actually pass the weighing system – Violation of fisheries, tax and custom regulations – Violation of OIML recommendations

    • Manipulation of weighing systems are wilful economic crime (fraud), including environmental crime

  • Marine life – our common responsibility www.fiskeridir.no

    How to approach this challenge in operative

    work?

    • When manipulation of weighing systems are discovered – “freeze” the situation if you have the legal authority – Secure technical evidence – Photos/videos

    • Approach as crime technicians

    – Crime scene – Huge variety of evidence/“silent witnesses” – Complicated and time consuming to investigate

    • Skilled personnel is strongly needed
