CONFIRMED PROJECT FACTS

What is confirmed for this project

Only the items in the table below are confirmed for this reference.

Project	Acuario Nautilus
Country	Peru
Year	2020
Application	Walk-through underwater acrylic tunnel
Total tunnel system length	29.96 m
Tunnel width	3,000 mm
Tunnel height	2,600 mm
Acrylic tunnel panel thickness	80 mm
Material and configuration	Cast PMMA, curved formed segments, with a curved corner section
PG Acrylic scope	Acrylic tunnel panel supply

How to read the 29.96 m figure: it is the total tunnel system length. It is not the dimension of one individual panel, and the 80 mm thickness is the panel thickness used on this tunnel — not a general recommendation for tunnels of similar size.

PROJECT OVERVIEW

The tunnel at Acuario Nautilus

Acuario Nautilus is a public aquarium in Peru. The acrylic tunnel is a walk-through run with a total tunnel system length of 29.96 m, 3,000 mm wide and 2,600 mm high: visitors move along a concrete walkway while the acrylic arch carries the water and the themed rockwork on both sides and overhead.

The run does not stay straight — it turns through a curved corner section, visible in the photographs taken from the tank side before flooding. The tunnel is built from 80 mm curved cast-PMMA segments joined in sequence, and the joint lines follow the arch at each panel edge.

PG Acrylic supplied the acrylic tunnel panels for the project in 2020.

PG ACRYLIC SCOPE

PG Acrylic's confirmed scope

PG Acrylic supplied the acrylic tunnel panels for this project. Installation was not part of PG Acrylic's scope here.

The scope is stated at that boundary and no wider — this page makes no statement about any other part of the project.

COMPARING A NEW PROJECT

Planning your own underwater acrylic tunnel

A tunnel that looks similar is not a specification. Geometry, spans, support conditions and water depth act together, so a new tunnel is reviewed from its own inputs. The geometry parameters, joint design and installation-sequence requirements are set out on the technical page.
