Remotely Operated Bio-inspired AM Underwater Robot

Canada’s international marine trade, accounting for 80% of its commerce with countries beyond North America, surged to an impressive $205 billion in 2015. In this dynamic industry, the maintenance and repair sector assume
a pivotal role in managing the life cycle costs of marine vessels, with approximately 72% of the budget allocated to its operation. The challenges faced are formidable, as unforeseen equipment failures, surface damage including
corrosion, biofouling, abrasion, and fatigue cracks due to seawater exposure, are all too common. Typically, the conventional approach entails transporting the damaged marine to a dry dock for repair, incurring substantial
expenses and logistical challenges.
To address these challenges, the possible deployment of a Metal Additive Manufacturing (MAM) equipment emerges as a transformative solution, significantly reducing the reliance on off-route docking for supply replenishment, maintenance, and overhaul. To harness this technology for underwater repair purposes, we introduce the “Remora MAM Bot”, a remotely controlled bio-inspired MAM robot. Drawing inspiration from the Remora fish, this innovative robot boasts a vacuum cap mechanism, allowing it to attach securely to various marine surfaces. By adhering to the marine vessel’s body, the Remora MAM Bot provides effortless access to damaged areas, rendering it invaluable for underwater repairs.
