Coastal Development Enhancement
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.
Coastal infrastructure adds significant surface area and physical structure to the sea - yet its rarely designed to support or benefit marine life. We believe the future is in smart design of such structures so that they increase the return on investment by providing surfaces and structure that create opportunities for nature and increase fish stocks and help them become more resilient to exploitation and maintain or even enhance biodiversity.
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'. Coastal housing developments such as those in the Middle East can be designed to become biosanctuaries that actually produce fish for the region.
We can provide design guidelines or products to help you:
- Enhance rock seawalls to increase abundance of a target species, eg. fish, lobster, corals
- Design fish friendly marinas and coastal developments with features below the waterline that enhance biodiversity or recreational value (eg diving, fishing)
- Design features that help offset loss of important habitat due to the development
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.
We provide customised services to meet your needs, as well as:
- ‘Better design below the waterline’. Recommendations of how coastal infrastructure can be cost effectively designed to increase biodiversity or target species
- Designed artificial reefs to compensate for loss of natural rocky outcrops or coral reefs, enhance fisheries (including recreational fishing reefs), enhance seawalls/breakwaters or jetties
- Independent advice of the feasibility and effectiveness of proposed reef restoration/compensation plans
- Coral relocation and propagation
- Coral reef restoration and/or enhancement
- Marine impact monitoring and reporting

Seawall Enhancement via addition of Concrete Habitat Panels
SOI Director David Lennon is excited to see phase two of SIMS World Harbour Project roll out which involves the addition of 500 concrete custom designed habitat panels to Sydney seawalls to increase oysters and biodiversity in general.
David has been involved in the project from conception through his affiliation with the Reef Design Lab which he co-founded with Alex Goad. Enhancing seawalls and designing new seawalls for increased biodiversity is an important advancement in coastal engineering design that David has been promoting since the 90's. SOI can provide a range of services for seawall design or enhancement. Contact us to discuss your project.
Papua New Guinea Coral Relocation
In Dec 2017, SOI was contracted by Pacific Marine Group to relocate over 260 priority corals out of the area where a sewage outfall trench was to be dredged.
The project was a success and bommies up to 3m in dia and 2m high were relocated to safety. We also relocated associated fauna such as numerous anenomes with clownfish, a range of other fishes living in the corals, as well as urchins.
Hyundai Power Plant Artificial Reef Design (Red Sea, Saudi)
SOI designed the artificial reefs to offset impacts from dredging and construction of seawater intake infrastructure for the power plant. We used three different reef unit designs and a total of 500 units in various configurations to recplicate natural bommies that were impacted and to provide productive habitat for commercial fish species.
Reclamation Offset (Arabian Gulf, Saudi)
SOI designed the artificial reefs to offset the impacts from reclamation of 4.4million m2 of sandy nearshore seabed. A total of 1,300 reef units of three different sizes were deployed in specific configurations to maximise ecological benefits.
Fish Friendly Marinas
Here's an article by SOI Director David Lennon in the Dec issue of the Marina Industry Associations magazine.
>> Fish friendly marina design
SOI can provide the full suite of services from assessing marinas and recommending strategies to increase fish habitat, to providing and deploying the most appropriate fish habitat. Retrofitting a marina is always the most costly option so if you are designing are marina, get in touch with us and we can show you the most cost and ecologically effective strategies to boost biodiversity and fish numbers.
Qater reef constructed to offset port impacts
SOI prepared the coral mitigation plan for the new Doha Port to reduce impacts of this important project and this included coral relocation and construction of a purpose designed artificial reef.
SOI's sister company Reef Arabia based in Bahrain, manufactured, delivered and deployed the concrete reef units for this mitigation requirement.
Culturally Sensitive Artificial Reef Design
Local customs and architecture are considered when planning new buildings...as underwater architects, we believe there are benefits of doing the same when designing a reef.
But its not just about designing a pretty replica for the seabed! The design must also appeal to the marine life of the area.
We describe a good example of how this can be done in our Tech Note 4 - download here .
World's First 3D printed Artificial Reef!
In a world first, an advanced construction sized 3D printer has been used by SOI to revolutionise artificial reef design and produce reef units that look and function like a natural reef, a major step forward in a bid to restore lost and damaged reefs around the world.

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 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"l.

SOI constructs first 'cod cave' 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. September surveys found a 1.03m Murray Cod right on top of a cod cave so that was very exciting and confirmation they are working. 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 and naval base construction which includes a 10km long shipping channel and impact footprint of 4.5km2. Our mitigation plan 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.
