Sustainable Oceans International Pty Ltd (SOI) recognises that there is an increasing awareness and demand for primary and compensatory restoration when important habitats such as reefs are impacted by dredging.

Industry bodies such as the International Association of Dredging Companies (IADC) promote and support better practices and they recently launched their fact sheet "Dredging Around Coral Reefs" which we highly recommend.
SOI has been established to specifically help infrastructure projects satisfy reef restoration or compensation demands.
For example we help you in the planning phase by identifying options to reduce impacts (or compensate for impacts) and we prepare a coral management plan that helps expedite your permit application and outlines in detail how corals will be saved and any recommended compensation measures.
SOI is the only company that provides a range of proven technologies for the task.
We can ‘rescue’ important coral colonies that are within the dredge impact footprint and relocate them to an appropriate safe area, or we can construct designed artificial reefs to replace lost structure and/or compensate for ecological services lost.
Our specialty is finding ways to reduce impacts your dredging may have on reefs or to repair or offset impacts that have occurred.
SOI works closely with your team to evaluate your Environmental Impact Assessments (EIA), Environmental Management Plans (EMP) and relevant project limitations to develop cost effective strategies to reduce or restore marine impacts to reefs.
We have worked directly for permitting agencies, environmental impact consultancies and major engineering consultancies therefore bring an understanding of each side’s needs.
We provide customised services to meet your needs, as well as:
We have demonstrated experience in delivering support for dredging projects – and have even worked within a tight 12-day timeframe to successfully relocate coral reefs out of harms way before a construction project in the Middle East. Read more.

The short presentation below outlines a few suggestions of how marinas can be better designed below the waterline to increase, maintain or even enhance marine biodiversity. This is quite straightforward and cost effective to do.
Our key focus is ‘better design below the waterline’ which we believe is an essential component of sustainable design and preventing a decline in aquatic biodiversity often associated with development. The International Association of Dredging Contractors (IADC) refers to this concept as 'building with nature'. Its all about building in a way that also 'creates opportunities for nature'.
Excellent progress has been made with sustainable design above the waterline therefore our role is to help you capitalise on better design below the waterline whether it be for meeting regulatory approvals, facilitating permits, corporate responsibility or to increase the project's value to stakeholders, community or environment.
Capitalising upon structure below the waterline is a bit like maximising the value of a basement or underground car park in an office block. Cities would have significant problems if developers didn't maximise the use of land by including below ground assets. And developers would have reduced returns financially if they didn't. Our philosophy is that traditional design of coastal structures is like building an office block and locking away the basement.
Consider us your underwater architects and aquascapers.
We can increase the value of your development by improving the marine environment and services provided or by adding unique underwater features.

Sustainable Oceans International Pty Ltd (SOI) provides leading international expertise on the design and construction of artificial reefs as well as the supply of artificial reef modules.
We are unique in that we are licensed contractors for several different designs of artificial reef modules and we custom design modules to suit your specific application.
SOI provides reef design and construction for recreational/commercial fishing reefs, deep water reefs for pelagic fishes, anti-trawl reefs, juvenile habitat enhancement, enhancement of coastal structures, or alternative fishing spots within or near Marine Protected Areas.
When it comes to designing reef units for your specific project, we follow a philosophy of biomimicry and 'innovation inspired by nature'. We spend hundreds of hours watching how marine life use different structures (natural and artificial) and we study the design of natural reefs in order to gain inspiration and design solutions for constructed reefs.
Our experts have worked with Government, NGO’s, coastal developers and oil industry around the world to provide effective fishing reefs.

Our experts have been involved in developing and pioneering coral propagation and transplanting techniques since 1996. We now have a range of proven techniques with greater than 80% survival.
We provide customised services to meet your needs, as well as:
Training Available in Reef CPR!
We have a range of proprietary training modules specifically designed for community programs, dive centres, volunteers and tourists that want to reduce impacts to reefs and facilitate recovery. We call it Reef CPR (coral preservation and restoration).
Thousands and thousands of hours are spent by divers underwater that could be spent conducting Reef CPR! Many divers are begging to help save the broken corals they have to swim past and they are willing to pay to be involved. With reefs in such a critical condition around the world, it is crazy to not take advantage of this willing workforce. Therefore every dive centre and resort in a coral area should have key staff that are trained in Reef CPR.
Our unique Reef Recovery Program includes Reef CPR and is the only training course available that combines the science, the art and the business model you need to implement an effective and sustainable reef restoration program.
This program has been designed for resorts and dive centres that need a fun and rewarding reef recovery program that is not only effective but generates its own revenue, therefore reducing financial pressure on you. We have all run our own dive centres and ecotours, therefore we understand your needs as a business owner or manager. We understand the need to maintain or enhance the customer experience, and professional presentation and training.
We customise the program to suit your specific application and objectives and we can help you determine the most important priorities for your area.
We recommend three key steps in our Reef Recovery Program and we can assist you with one of them or all of them.

Step 1 - Identifying and reducing existing reef impacts
Step 2 - Implementing actions that help natural coral recolonisation and survival
Step 3 - Assist recovery by transplanting and/or propagating corals

Advances in technology and methods now make reef restoration and mitigation of development impacts to reefs feasible in a large number of cases. Our Team have been involved in reef restoration projects in Asia, Middle East, Caribbean and the US.
Restoration strategies need to be cost effective and take into consideration local resources and future management of the area. In some cases it is best to allow natural recovery and we will advise if we believe this is the case.
Funding restoration can be via a range of sources including the tourism industry and we are experienced in identifying opportunities and sustainable funding strategies.
Reefs are one of the most diverse living structures on the planet and reef restoration often requires a range of strategies and technologies. SOI is the only company that provides a range of proven technologies for the task.

Roy to the Rescue!
As part of our contribution to World Oceans Day and the theme of 'Youth: the Next Wave for Change' we are excited to introduce three enthusiastic volunteers that want to share with kids important messages regarding reef restoration and how to help keep our reefs healthy and more resistant to climate change.
Designed for resort programs, marine ed centres, community groups and schools, the Activities can be downloaded and copied and used as you wish. We will be continually working on new Activities and welcome your input.
The three volunteers are:
Roy Sharpie a long spined urchin (Diadema antillarum)
Aristotle Acropora Amadeus (Ari) a branching coral who likes the finer things in life
Barry the Boulder Coral (Bazzer) who is big, lived a long time and key building block in the reef
Activity #1: the value of urchins on the reef
This first Activity is simple but includes a very important message.
Think of a reef as a city...
Healthy reefs are vibrant underwater cities providing opportunity, food and refuge. Unfortunately like some cities, they too can become the equivalent of slums...providing limited opportunity, limited food and poor quality refuge.
Of the 109 countries with coral reefs, 90 of them are being damaged due to tourism (TIES 2006). Our goal is to help implement strategies to reduce this impact and restore the underwater slums back to vibrant healthy neighbourhoods.

Photo: reef units loaded on barge in Bahrain for construction of commercial fishing reefs. SOI partnered with local company Reef Arabia to design and construct ten reefs around Bahrain, the first initiative of its kind in the Arabian Gulf. SOI provided three unique reef unit designs for the project that are tailored to the local species and culture.
Applications for Multipurpose Artificial Reefs
Multipurpose Artificial Reefs can be constructed to protect eroding beaches of resorts while providing a recreational snorkelling asset, or they can be used to enhance local fish stocks while offsetting loss of habitat due to development.
Our team has in depth experience in designing and building artificial reefs in the US, Middle East, Asia, Australia, Mediterranean and Caribbean.
We provide customised services to meet your needs, as well as:

Mini multipurpose breakwater designed to support a healthy oyster population which will help increase biodiversity, increase juvenile fish habitat, reduce suspended solids and reduce boat wash that is eroding estuary banks.

Multipurpose artificial reef in the Grand Cayman (above photo) and Antigua (below photo). This type of breakwater is ideal for resort areas as it is visually less distracting than large rock seawalls, provides a snorkeling and diving attraction, enhances biodiversity and maintains a healthy flow of water to the back lagoon area.
The breakwater can be designed to help offset damage to natural reefs (and/or loss of biodiversity) and this may include relocation of coral from dredge areas to the the breakwater where we use a range of techniques we have developed to secure the coral to the concrete modules.

Contact us to discuss your artificial reef project.

Of the 109 countries with coral reefs, 90 of them are being damaged due to tourism (The International Ecotourism Society, 2009).
Our core belief: tourism can be a tool for reef preservation.

Reefs are like Cities
We view healthy reefs (including constructed reefs) as underwater cities.
They provide a diverse range of opportunities for marine life, a variety of food and a range of nooks and crannies for the various inhabitants that are essential to create a rich and diverse ecosystem.
Unfortunately coastal development in many countries is turning these diverse and rich cities into slums.
Underwater slums that provide limited opportunity, limited diversity, a limited range of food and poor quality refuge.
We provide the technology and strategies to help restore these 'slums' and reduce further degradation of reefs. We believe tourism can be a tool for reef preservation rather than reef degradation.
Contact us now to discuss how we can help.
We use Marine Protected Areas (MPAs) as a generic term for a range of different management strategies for marine habitats that are considered important and in need of better controlled use. They may be labelled marine parks, voluntary no take zones, locally managed marine areas etc.
Our experts have direct experience of setting up MPAs in places such as Mauritius, and MPAs can be a very effective and essential component of reef and fishery restoration programs. For example artificial reefs constructed as part of a restoration program can be used to reduce fishing pressure on degraded natural reefs or provided as compensation to fishers for areas closed to fishing. MPAs can also be used to maintain healthy connectivity between important habitats and natural or artificial reefs.

We have a winner!
Sustainable Ocean Innovation Award 2012
...and the award goes to...GhostNets Australia for their work in northern Australia tackling the serious problem of lost fishing nets called 'ghost nets'.
The group has found ghost nets measuring 10km long and recorded a myriad of marine species that get entangled as the nets drift along with the currents. The litany of marine casualties include turtles, dolphins, sharks, seabirds, crocodiles, rays and of course, multitudes of fish. The destruction caused by ghost nets continues as they near shore, often wrapping themselves around delicate coral reefs and coastal mangrove systems.
"The GhostNets Australia program is a fantastic example of innovation in action. Solving our environmental problems needs a healthy dose of lateral thinking in order to first see a solution and then brainstorm a way to make it happen" said David Lennon, director of Sustainable Oceans International.

SOI constructs first 'cod house' to help save Murray cod
Murray cod are Australia's largest freshwater fish and overfishing and loss of essential habitat has decimated their numbers. SOI has been contracted to design and construct a concrete unit to help restore some of the essential breeding habitat the fish require. Sidescan image by ACT Government.

SOI wins 2 Year Contract - Bahrain
SOI and partner Reef Arabia have won a two year contract to design, build and monitor 10 artificial reefs around Bahrain.

>>Further details and photos of deployment of first reef in Bahrain
>>Bahrain newspaper article in Arabic
Four reefs have been deployed thus far. This is the first project of its kind to be constructed in the Arabian Gulf and the first to use custom reef units (designed by SOI) specifically for the local species.SOI Completes Coral Mitigation Plan for New Doha Port
SOI conducted the necessary surveys and prepared the coral mitigation plans for the New Doha Port construction. This included accurate coral surveys to quantify the size, type and number of corals within the imperiled and threatened zones, and detailed recommendations on relocation methodology, relocation sites and compensatory artificial reefs to offset loss of productive reef structure.
