DSA has diverse experience in designing mooring systems for a wide variety of applications and marine environments. Our team uses its expertise in hydrodynamics to deliver client-centred engineering services from its Canadian offices.

We have engineered mooring systems for applications such as marinas, ferry terminals, water reclamation barges, floating breakwaters, docks, and floating pipelines. For offshore or high-energy nearshore areas DSA has designed multi-leg moorings for fish farms, feed barges, shellfish longlines, wave energy devices, tidal platforms, and more.

Following recognized standards such as API-RP-2SK, DNVOS-E301, IEC62600-10, and ISO19901-7, DSA ensures that ultimate, accident and fatigue limit states are evaluated to minimize risk and satisfy insurance or classification requirements. We help clients to establish the basis of design, by determining the wind, wave, and current
conditions to use in the analysis.

We use industry-recognized ocean engineering software to calculate the effects of current, wind and wave loading on the mooring system and marine structures. CFD, dynamic analysis, and FEA are used during the process.
