Employing a combination of methods, including literature review, computational modeling (with Maxwell 2D software), laboratory experiments, in situ sensor measurements, and field trials, the research assessed EMF characteristics and the effectiveness of mitigation strategies like cable shielding, armour enhancement, proper earthing, and burial at a depth of at least 1 meter. Key findings demonstrated that while improved cable design and burial reduce external EMF exposure, magnetic fields persist outside cables and both field types remain within ranges detectable by some sensitive marine organisms.

The cross section of a three-phase cable is uniform along the axis of the cable; therefore the field patterns in an entire cable can be modelled by simulating the fields in its cross-section (ie. 2-D). The 'Maxwell 2D' software program allows the simulation of electromagnetic and electrostatic fields in structures with uniform cross-sections15 by solving Maxwell’s equations using the finite-element method. The program divides the modelled structure into many smaller regions, which are represented as multiple triangles. The collection of triangles is referred to as the finite element mesh. The program computes the electric and magnetic fields at the nodes (vertices) of triangles. The solved fields at each node are then represented as a separate polynomial and fields at points inside the triangles are interpolated from these nodal values.
