Design Basics
The design requirements of any OceanGuard system is detailed in 3 typical steps.

    1. Hydraulic Design & Configuration
    2. Water Quality Design
    3. Mass Load Design

1. Hydraulic Design & Configuration
All OceanGuard inserts must be designed to ensure that the hydraulic requirements of the system are met
without adversely impacting the upstream hydraulics (limiting the likelihood of localised flooding).

2. Water Quality Design
Ocean Protect recommends and uses the widely endorsed Model for Urban Stormwater Improvement
Conceptualisation (MUSIC), which makes it easy to correctly sizing an appropriate StormFilter system for your
site.

A complimentary design service which includes MUSIC modelling is provided by the Ocean Protect
engineering team. Simply email your project details to [email protected] or alternatively you
can always call one of our engineers for a discussion or to arrange a meeting in your office. The team will
provide you with an efficient design containing details of the devices required to meet your water quality
objectives together with budget estimates, product drawings and the MUSIC (.sqz) file.

Alternatively, you can download the MUSIC treatment nodes for the Ocean Protect products from our
website (www.oceanprotect.com.au).

When designing/modelling an OceanGuard system for water quality purposes in MUSIC, a single GPT node is
utilised. The GPT node is utilised with relevant removal efficiencies inserted. These parameters can vary
based on the jurisdiction (authority) of your project, relevant details can be obtained from Ocean Protect.
When modelling, the high-flow bypass is modified in node by adding the total number of Ocean Guards
installed and multiplying this number by 20L/s, eg 10 x Ocean Guards = 0.2m3/s.

All details such as drawings, specifications and maintenance manuals can also be downloaded for integration
into your project’s documentation. Additionally the Ocean Protect team is available to review your model
and provide additional assistance and guidance on the configuration of the OceanGuard system(s) for your
project.

3. Mass Load Design
Always be mindful of the magnitude of upstream catchment areas pay particular attention to perceived dirty
or high loading sites. The Ocean Protect team can provide assistance and details on this process.
