Program Overview

In this virtual reality module, participants will have access to a simulated excavation site, focused on completing gas pipeline hot tapping tasks in the neighborhood. The module includes abandonment, main extension and cut-out scenarios. Using available materials and resources, the player must determine the order of actions and complete the task.

 

Core Learning Objectives

  • Safety Measures — take all necessary safety measures

  • Work Sequence — accomplish task according to the technological process

  • AOC Recognition — notifying and dealing with AOCs

  • Reporting/Documentation — steps taken / resolution / documentation

Tools

  • Laser Pointer — to interact with menus and objects in this experience, aim the laser pointer at an interactable item and pull the controller trigger to select it

  • Soap Spray — to test for a leak, aim the spray and pull the controller trigger:

    • If bubbles appear, there is a leak.

    • If there are no bubbles, the leak is coming from somewhere else.

  • CGI Tool — to take a reading, aim the tool and pull the controller trigger.

 

Instructor Mode

Use the "Add Scenario" screen in the lobby to build a specific scenario. You will be able to select:

  • Scenario (1-3)
  • Turn Hints ON / Turn Hints OFF
  • How Many AOCs are present
  • Which AOCs are present

 

How to Get 100%

There are 3 different scenarios that can appear within the module. If you are not using Instructor Mode, these will appear randomly.

 

Note: In this module, if a user performs the wrong action for the second time, a warning window will appear again and the correct action will be automatically performed.
