Sustainable Oceans International

Sustainable Oceans International Artificial reef design, coral restoration including training in our Reef CPR course for Rec divers.

Sustainable Oceans International is a leading consultancy to dredging companies, the oil industry, government, resorts and NGO's. We specialise in the preparation of Coral Mitigation Plans (also known as Coral Management Plans), coral relocation and design and construction of compensatory artificial reefs to offset loss of essential fish habitat. We use a range of proprietary reef restoration and

reef rehabilitation strategies. As part of a sustainable development strategy we help you 'create opportunities for nature' by including design features within your breakwaters, rockwalls or coastal development that help maintain or even enhance biodiversity. If you are in the process of:

>Planning or designing a coastal development
>Seeking a dredging permit
>Restoring a degraded reef; or
>Require an artificial reef to improve fishing, compensate for impacts, reduce beach erosion or drive tourism

Sustainable Oceans International consultants have the experience to help your project succeed. Our team are passionate about conserving our marine environment and have a combined knowledge of over 60 years with marine impact mitigation and have worked on complex projects across the Middle East, Asia Pacific, Africa and Europe.

CHALLENGE #1
How do you government, companies and organisations commissioning artificial reefs judge and assess artificial reef units and their suitability for their objectives? Most do not have the experience or training in how to compare reef units.

CHALLENGE #2
How do artificial reef designers or those working with artificial reef designers effectively discuss the proposed designs and the strengths and weaknesses of each? With a set of grading criteria we think it will help designers know what to focus on improving or reducing.

We are building basically houses for marine life. On land we have developed ways to describe and judge and price our dwellings - one bedroom, 4 bed, 2 car garage, 1 bathroom, patio, entertainment room, pool, garden etc etc. But for reef units there is no method yet and can be confusing.

We have been thinking about this for quite awhile and have developed a grading system that grades reef units on the following essential criteria (draft! open to adding more):

1. Opportunities for Nature (how many features does it have that provide opportunities for nature)
2. Cost (manufacture, transport, deployment)
3. Sustainability (including carbon footprint)
4. Longevity
5. Stability
6. Suitability for Target Species (no good scoring 5 star if the features aren't actually any good for target species!)

We have built a spreadsheet where reef units are scored against these criteria by answering a range of questions. A score for each criteria is then produced.

It’s quite complex and we will be sharing it next week once we figure out how to sum it up and describe, and I'll rate a few generic no-brand reef units as examples.

We are keen for feedback on practicality and usefulness!!

Stand by...and have a great weekend!

Our Oyster Triangle reef units proving very effective in port Phillip bay, Melbourne.

Excellent pilot project that first seeded the Oyster Triangles with oysters and then deployed them to accelerate productivity.

Growth has been fantastic confirming the site has the right food and flow and not surprising as it was the site of a very large mussel reef back in the 70’s until it was trawled.

These Oyster Triangles are ideal for estuary bank stabilisation from boat wash while providing productive habitat. And of course ideal for enhancing productivity around or inside larger concrete reef units or for coral reefs. Our goal in designing reefs is always a diversity of habitat to help increase the variety of food. It’s like making sure there are sufficient cafes, supermarkets for the large office towers!

Reach out if you might have an application for these units.
