Drafting a new marina development plan is an exciting opportunity, but it’s also a major engineering and planning challenge. From choosing the right site to designing for long-term resilience and profitability, there’s a lot to consider.  At International Coastal Management (ICM), we’ve been delivering marina developments for over 35 years, helping clients navigate coastal complexities, approvals, and commercial realities to deliver high-performing waterfront infrastructure.  Why a Purpose-Built Marina Matters  Marina developments, if not designed correctly, can run into major problems down the line, including wave damage, downdrift erosion impacts, sedimentation, unusable berths, or costly redesigns.  That’s why it’s essential to bring in coastal and marina engineering consultants from day one. A well-designed marina isn’t just about the best quality berths and pontoons, it’s about getting every component right:  Wave protection  Water circulation and flushing  Vessel access and safety  Environmental compliance  Infrastructure design and staging  Utility and service integration  Financial feasibility  ICM’s Marina Development Plan With over 35 years of expertise, ICM acts as a technical advisor, coastal engineer, and project delivery partner. Here’s how we guide clients through a new marina development:  Step 1: Site Feasibility & Coastal Condition Assessment  We start by assessing whether the site can physically support a marina, and what kind of design it will require. This includes:  Wave climate and wind exposure  Tidal range and water depth  Sediment transport and erosion risks  Environmental constraints (seagrass, mangroves, habitats)  Circulation and flushing capacity  Access to navigation channels  We also assess potential dredging needs, permitting pathways, downdrift impacts, and coastal risks like storm surge and flooding.  Step 2: Concept Layout & Vessel Planning  Our Marina Engineers develop an optimised layout based on:  Intended user types (e.g. recreational, commercial, superyachts, megayachts)  Vessel size mix and maneuvering space  Lease boundaries or development envelope  Shoreline conditions and site geometry  Long-term staging plans  We use AS3962 and international best practice to develop safe, efficient, and cost-effective configurations, backed by coastal modelling and hydrodynamic analysis.  Step 3: Breakwater & Wave Attenuation Design  Depending on the site’s exposure, we determine whether wave protection is required, and how best to achieve it. This may include:  Rock breakwaters  Floating wave attenuators  Low-lying structures like geotubes  We model wave penetration into the marina basin to ensure vessel safety and comfort under all weather conditions.  Step 4: Environmental & Regulatory Coordination  We lead the environmental and permitting aspects of the project, including:  Environmental impact assessments  Stakeholder consultation  Dredging and disposal approvals  Habitat protection plans  Compliance with local, state, and federal frameworks  Our deep experience in coastal regulation helps streamline approvals, without compromising sustainability.  Step 5: Engineering Design & Tender Support  We prepare or review technical marina designs for:  Pontoons and mooring systems  Revetments and shoreline protection  Dredging and sediment management  Utility services (power, water, sewage, fuel)  Public access and landside amenities  Our expert team ensures project ease by leading contractor engagement, supplier coordination, and procurement support  Step 6: Construction & Project Delivery  Once construction begins, ICM can provide:  Contractor oversight  Fabrication checks and pre-installation inspections  Progress assessments  Practical completion certification  We also support post-installation monitoring to ensure water quality, vessel access, and structural performance meet expectations.  Key Elements of a Successful New Marina  ✔️ Integrated Layout – Efficient vessel access, berthing, and support services   ✔️ Wave Protection – Engineered for storm resilience and user comfort   ✔️ Utility Infrastructure – Power, water, fueling, sullage, lighting, fire systems   ✔️ Environmental Harmony – Minimal ecological disruption and strong flushing   ✔️ Future-Proofing – Space for expansion, changing vessel sizes, and user trends   ✔️ Smart Materials – Durable, low-maintenance, and climate-ready   ✔️ Financial Viability – Berth mix and layout designed to optimise ROI  Thinking of Building a Marina?  Whether it’s a boutique waterfront extension or a multi-stage international marina development, early engineering input is essential to avoid costly rework, design limitations, and environmental issues.  ICM is your trusted partner from feasibility through to delivery. Let’s talk!

Following repeated cyclone damage and erosion to the beach adjacent to the Bowen Golf Club, Whitsunday Regional Council engaged ICM to develop a seawall solution to prevent further erosion. ICM designed a durable seawall using repurposed seabees units from a historic Bowen project to prevent future coastal recession and protect golf course assets. Project Details Client: Whitsunday Regional Council Date: 2016 Location: Bowen Golf Club, Queensland About This Project The Challenge: Coastal erosion triggered by multiple cyclones had begun to threaten the beach adjacent to the Bowen Golf Club. The Council sought a cost-effective solution using available materials to minimise project costs while delivering shoreline stability. The Solution: ICM was engaged to assess the viability of using Seabees units - originally from a historic project in Bowen - and to develop a tailored seawall design for the unique conditions of the site. A condition review of existing Seabees units was undertaken, with a stability assessment of the seabees seawall using exiting available units. A concept and detailed design was completed based on the condition and geometry of the existing Seabees. Key structural elements, including the filter layer, toe protection, crest detail and seawall return were engineered for optimal performance. The project successfully reused 266 existing Seabees units, delivering both cost-efficiency and durability. The seawall was constructed from September to November 2017, with ICM providing ongoing support to ensure successful implementation. This project showed how innovative re-use of materials combined with expert coastal engineering, can deliver a cost-effective and resilient erosion solution." - Aaron Salyer, International Coastal Management Services Provided: Seabees condition review Concept design for seawall layout Detailed design including toe, crest, and filter layer Design of seawall return Get in Touch ICM has delivered seawall and coastal protection projects across Queensland using innovative, site-specific designs tailored to natural forces and local materials.

With over 35 years of experience as trusted marina engineering consultants, our team at International Coastal Management specialises in practical, cost-effective marina upgrades that align with both technical performance and user needs. Whether you're looking to improve berth layouts, enhance resilience to wave impacts, or preparing for larger vessels, our team provides independent, end-to-end support, from feasibility through to design, approvals, and delivery. Why Upgrade a Marina?  Over time, even the best-built marinas face pressure from:  Larger vessel sizes (including superyachts and megayachts)  Evolving user demands - for deeper drafts, more amenities, improved services, enhanced marina design   Regulatory changes - environmental and safety standards changing  Structural wear and tear - pontoons, revetments, breakwaters and piles all age and need upgrading at some point Sediment and water quality issues - many marinas can suffer from infill and circulation problems  A well-timed upgrade can address these issues, restoring performance, increasing revenue generation, and enhancing the user experience.  How Independent, Expert Marina Engineering Advice Can Save You Money  ICM is not a supplier of marina products or pontoons, we’re independent coastal engineers. That means our only goal is to deliver the best outcome for your marina, based on performance, usability, budget, design , and long-term success. Our marina development plan follows a proven roadmap:  Step 1: Comprehensive Condition Assessment  We begin by physically assessing your current infrastructure, including pontoons, revetments, seabed conditions, wave exposure, and site functionality. This includes:  Structural performance and deterioration  Operational constraints  Revenue optimisation opportunities  Environmental conditions (waves, tides, sedimentation)  This gives us a clear, data-backed understanding of where the marina is today, and where it could go.  Step 2: Concept Development & Feasibility Analysis  Based on the findings, we generate upgrade options tailored to your marina goals. This can include replacing aging docks, expanding the number of berths, or improving wave protection. Our team evaluates:  Marina Engineering feasibility  Cost-benefit analysis  Coastal processes and wave climate  Environmental permitting pathways  Revenue potential  We also identify any dredging, breakwater improvements, or shoreline stabilisation that might be required.  Step 3: Smarter Layouts for Future Use  Using modern modelling tools and marina design guidelines (including AS3962), we design new layouts that reflect:  Changing vessel mixes (e.g. more 20m+ vessels, multihulls)  Superyacht or commercial requirements  Optimised fairway widths, turnaround space, and berth orientation  Safe tidal and wind access  Opportunities for additional revenue (charter berths, longer stays)  Our founder, Angus Jackson, helped lay the foundation for modern marina design in Australia as a member of the original Australian Standards Committee for marina guidelines in 1991. These standards (AS3962) remain a national benchmark today.  Step 4: Coordinated Delivery & Stakeholder Engagement  We coordinate across your entire project team, working closely with:  Pontoon and marina hardware suppliers  Marine contractors  Environmental consultants  Approval authorities  Internal stakeholders (e.g. yacht club or marina committees)  ICM handles everything from pre-approval engagement to design reviews and tender support. Our project managers ensure your best interests are protected from start to finish.  Step 5: Construction Oversight & Post-Installation Monitoring  Once construction is underway, we stay involved. ICM oversees:  Fabrication checks before pontoons or components leave the yard  On-site contractor supervision and quality control  Compliance inspections and final sign-off  Post-installation monitoring to confirm performance  In a recent marina project, a supplier had proposed an oversized, costly system to our client. We reviewed the requirements and provided the client with a more economical option that better suited the marina’s long-term needs, saving significant capital while delivering a more functional design.  Common Marina Upgrade Scenarios  Every marina upgrade is unique, however here are just a few examples of situations our marina engineering consultants frequently support:  Aging pontoons that no longer meet safety or usability standards  Marina layout that doesn’t suit today’s vessel mix  Increasing maintenance costs due to sedimentation or poor flushing  Dredging needs or water depth concerns for larger boats  Interest in attracting superyachts or high-value vessels  Need for updated utility infrastructure (power, sullage, fire systems)  What You Gain From an ICM Led Marina Upgrade  ✔ Independent advice that puts your needs first   ✔ Optimised design that enhances functionality and revenue   ✔ Regulatory compliance through strong environmental support   ✔ Reduced capital costs through smarter, leaner layouts   ✔ Peace of mind with specialist marina engineering support through the entire process  Upgrading a marina is an opportunity to rethink how your site performs, earns, and grows. At ICM, we bring the technical depth and project delivery expertise to make your marina development a long-term success.
