What OÜ Lainemudel does

OÜ Lainemudel is an Estonian private limited company founded in 2015 and headquartered at Pärnu mnt 131b, Tallinn, providing consultancy and numerical modeling services for coastal engineering and management. Its core service areas are coastal process expertise and modeling, water level and flooding analysis, wave modeling for coastal structures, sediment and particle (including oil, nutrient, and pollution) transport modeling, and consultancy on the design and management of coastal structures. The firm applies established physics-based numerical simulation tools, specifically the SWAN wave model (developed in Delft), WAM, COULWAVE, and REEF3D, to quantify wave parameters, sediment movement, and hydrodynamic conditions for ports, harbors, breakwaters, and shore protections.

The business is operated as a single-leader professional consultancy by Rain Männikus, PhD, a chartered civil engineer at EstQF Level 8 specializing in coastal (port) structures. Revenue is generated on a project-based professional services basis, with field measurements and structural design delivered through implementation partnerships, notably Estkonsult OÜ for structural engineering design and Mareterra OÜ for coastal and structural design, project management, and audits. The customer base includes major Estonian port authorities (AS Tallinna Sadam, AS Saarte Liinid, Port Noblessner), municipal governments (Kuusalu, Viimsi, City of Pärnu), and engineering and construction firms (Nordecon AS, K-Projekt, Skepast & Puhkim, Estkonsult, Topmarine), with projects completed in both Estonia and Latvia.

The firm differentiates on scientific rigor, underpinned by co-development partnerships with the Laboratory of Wave Engineering at Tallinn University of Technology, the Ecology Center at Tallinn University, and the Institute of River and Coastal Engineering at Hamburg University of Technology, plus a minor partnership with NTNU Trondheim. Distribution is sales-led through direct professional consulting relationships and referral networks, supplemented by university lectures, government seminars, and scientific publications on Gulf of Riga water level dynamics. Training materials and seminars are offered as an add-on service line.

Core offering

OÜ Lainemudel is a coastal engineering consultancy that delivers numerical modelling and analysis of waves, water levels, sediment transport, and pollution spread for ports, harbours, breakwaters, and other coastal structures. The firm serves clients across Estonia and Latvia, ranging from major port owners to individual coastal property owners seeking advisory on shoreline exposure and coastal risk.

Product overview

OÜ Lainemudel is a consultancy and engineering firm specializing in coastal and marine engineering services. Established in Estonia in 2015, the company offers a unified suite of expert services rather than a software product platform. The core offering comprises six interconnected service areas: coastal process expertise and modelling, water level and flooding analysis, wave modelling using numerical models (SWAN, WAM, COULWAVE, REEF3D), sediment and particle transport modelling, coastal structure design and project management through partner Mareterra OÜ, and training materials. These services are delivered as consultancy packages rather than standalone software products, providing clients with scientific analysis and engineering solutions from initial concept through construction and maintenance.

Functional benefit

Products and services

• Numerical Wave and Water Level Modelling Numerical modelling and analysis of wave action and water level conditions for ports, harbours, breakwaters, and coastal structures, using established scientific computing tools to support design, planning, and risk assessment. Targeted at port owners, harbour operators, and coastal property owners in Estonia and Latvia.
• Sediment and Pollution Transport Analyses Numerical analysis of sediment movement and pollution dispersion in coastal waters, supporting dredging decisions, environmental compliance, shoreline change assessment, and water quality evaluation for ports, harbours, and coastal sites in Estonia and Latvia.
• Port and Coastal Structure Engineering Consulting Project-based coastal engineering consultancy covering the design, assessment, and advisory support of ports, harbours, breakwaters, and other coastal structures. The engagement integrates wave, water level, and sediment/pollution analyses where required, and is delivered to major port owners as well as smaller coastal clients in Estonia and Latvia.
