We design and engineer ship-lifts, slipways, and boat cradles tailored to New Zealand's coastal and marine environments. Our solutions focus on maximising safety, reliability, and operational efficiency for transporting vessels for maintenance, repair, or storage.

Ship-lift Design - safe, efficient vertical lifting of vessels via advanced mechanical systemsSlipway Design - slipways for safe launch and retrieval of vessels with structural integrityBoat Cradle Design - cradles that securely support vessels, tailored to each vessel's dimensions and weightSafety and Compliance - non-slip surfaces, emergency stops and secure locking systemsEnvironmental Considerations - measures to minimise disruption to coastal and marine ecosystems

We specialise in the design and construction of seawalls, breakwaters, and groynes that provide robust and sustainable coastal defense. Our solutions are tailored to New Zealand's unique coastal environments to mitigate erosion, protect shorelines, and enhance community resilience.

Seawall Design - seawalls protecting shorelines from erosion and wave action using concrete, stone or steelBreakwater Design - breakwaters reducing wave energy to create calm waters for harbors and marinasGroyne Design - groynes that trap sediment and stabilise beaches, reducing longshore driftEnvironmental Impact Assessment - assessments of effects on local ecosystems and marine habitatsStructural Integrity and Maintenance - structures designed for long-term performance in marine environments

We provide specialised assessments to evaluate the impacts of coastal erosion and rising sea levels, offering actionable insights and strategies to mitigate risks. Our assessments are grounded in the latest scientific research and tailored to New Zealand's diverse coastal environments.

Coastal Erosion Assessments - analysing shoreline changes to predict erosion and identify vulnerable areasSea-Level Rise Impact Assessments - modeling sea-level rise scenarios and their impactsClimate Change Adaptation Planning - integrating assessments into broader climate adaptation plansEnvironmental and Regulatory Compliance - meeting NZ regulations and supporting sustainable coastal management

We specialise in designing effective coastal protection solutions that safeguard New Zealand's shorelines while promoting sustainability. Our designs are tailored to each site, integrating engineering expertise with environmental considerations to create resilient, adaptive coastal defenses.

Seawalls and Revetments - robust structures protecting against coastal erosion and wave actionBreakwaters and Groynes - structures managing sediment movement and reducing wave energyBeach Nourishment and Dune Restoration - rebuilding and stabilising eroded shorelinesHybrid Solutions - combining traditional engineering with nature-based solutions such as living shorelinesEnvironmental Impact Assessment - assessments of effects on local ecosystems and communities

We offer comprehensive design and repair services for marinas and wharves, ensuring these structures are both functional and resilient. Our coastal engineering expertise lets us create and maintain facilities that withstand New Zealand's challenging marine environments.

Marina Design - marinas with floating docks, fueling stations and utilities for a range of vesselsWharf Design - wharves supporting commercial and recreational activities, focused on load capacity and safetyRepair and Maintenance - addressing structural degradation, corrosion and marine damageEnvironmental and Safety Compliance - compliance with NZ coastal management and safety regulations

We provide comprehensive structural assessments that evaluate the condition, performance, and safety of existing structures. Our experienced engineers identify potential issues and recommend effective solutions to maintain the safety and functionality of your assets.

Condition Assessments - evaluating foundations, load-bearing walls, beams and columnsSeismic Assessments - determining structures' ability to withstand earthquakesDamage Assessments - assessing damage from disasters, accidents or aging and repairs neededLoad Capacity Analysis - ensuring structures can safely support intended loadsCompliance and Certification - meeting NZ regulatory requirements with documentation

We provide specialised services in analysing and designing berthing and mooring systems, as well as conducting detailed wave studies. Our expertise ensures facilities are optimised for safety, stability, and operational efficiency, tailored to New Zealand's coastal and marine environments.

Berthing and Mooring Design - systems safely accommodating vessels of various sizes with secure dockingWave Studies - analysing wave patterns, heights and forces to inform structure designDynamic Analysis - assessing mooring and berthing performance under storms and high wavesEnvironmental Impact and Compliance - designing systems with minimal disruption to marine ecosystems

We offer comprehensive services in port planning and channel design tailored to New Zealand's coastal regions. Our expertise ensures ports and channels are designed to handle current and future demands while maintaining safety, environmental stewardship, and operational efficiency.

Port Planning - master plans for new and existing ports, including layout and infrastructureChannel Design - navigation channels for safe, efficient vessel access considering tides and sedimentationEnvironmental and Impact Assessments - assessing effects on marine ecosystems, water quality and coastal processesSafety and Navigation - breakwaters, navigational aids and emergency access routes

We provide comprehensive support for obtaining the necessary environmental approvals, ensuring projects comply with New Zealand's stringent environmental regulations. Our team navigates the complex approval processes on your behalf so you can focus on project execution.

Marine environments pose a distinctive set of engineering challenges: materials durability, wave loading, ship berthing and mooring forces, tidal effects and the difficulty of doing work from barges and isolated sites. Our maritime team has detailed practical experience of all of those, and we have built our service around understanding how water-based and isolated construction actually gets delivered.

We design the full span of maritime structures that ports, councils and private operators rely on.
