The problem

When clarity fades, the whole experience suffers.

Over time, acrylic viewing panels scratch, haze over, and accumulate algae and biofilm. Visibility drops, light scatters, and the underwater view your visitors came for loses its impact — most visibly on your largest, most prominent panels.

  • Fine scratching and surface haze
  • Algae, biofilm, and soft marine deposits
  • Reduced transparency and contrast
  • Distracting reflections and light scatter

HOME-problem-after

The same panel restored to clarity (pairs with HOME-problem-before to drive the haze → clarity transition).

Recommended: 1600×1000

Demonstration: as this scrolls into view, the panel sharpens from hazy to clear.

The operational challenge

Maintaining large panels is rarely simple.

The difficulty is rarely the polishing itself — it's everything around it. Access, timing, and the realities of a living, operating site shape what's actually possible.

  • Hard-to-access tanks

    Large and irregular geometries make panels difficult to reach safely and thoroughly.

  • Disruptive draining

    Lowering or draining water is costly, slow, and stressful for the exhibit and its animals.

  • Complex diver work

    In-water intervention by divers is demanding, time-bound, and expensive to coordinate.

  • Repetitive cleaning load

    Internal teams lose hours to recurring manual cleaning instead of higher-value work.

  • Live-environment constraints

    Work must fit around visitors, animal care, filtration, and opening hours.

  • Downtime pressure

    Every closed exhibit or roped-off panel affects the visitor experience and revenue.

HOME-method

Robot entering frame on a panel; supports the 'method' moment with technical overlays.

Recommended: 1920×1080 (or 4:5 crop)

The Abyssnaut method

Specialized robotics, applied with PMMA expertise.

We don't lead with the robot — we lead with the panel. Every intervention starts from the material, the site, and its constraints, then applies the right combination of methods.

  1. Dedicated underwater roboticsPurpose-built systems work in the water, reducing the need to drain or close exhibits.
  2. PMMA-specific polishing expertiseDecades of acrylic know-how guide how each panel is treated.
  3. Manual dry polishing where it fitsA complementary method for visitor-side, upper, and dry-access areas.
  4. Robot-cleaner systemsFor recurring maintenance that keeps clarity from degrading in the first place.
  5. A field-driven approachMethods are selected per site, around its real constraints — not a fixed template.

Solutions

Three solutions for acrylic clarity.

Used on their own or together, depending on the panel, the access, and how often maintenance is needed.
