Final values can only be determined through project-specific engineering analysis, detailed design, and formal technical and commercial evaluation.
01
...faster than conventional marine construction
What if marine structures could be delivered up to 4 times faster than even the most efficient conventional offshore construction methods? This acceleration is achieved by shifting the majority of construction activities away from the marine environment. In typical projects, up to 90% of all assembly work is carried out on land, under controlled conditions. As a result, offshore operations are reduced to installation and final structural integration, significantly shortening construction timelines and minimising weather dependency.
02
...more cost-efficient by design
What if marine construction could be at least 3 times more cost-efficient than the most economical, reliable alternatives available today? HYDRANTULA structures are designed to use material only where it is structurally effective. For example, a marine wall with a length of 100 meters, a height of 6 meters and a width of 3 meters can be realised with approximately 100 cubic meters of concrete, rather than massive solid volumes. This material efficiency directly translates into lower construction, transport and installation costs.
03
...more durable,
resilient and serviceable
What if marine structures could be engineered for a guaranteed operational life of at least 60 years, with inherent resistance to harsh marine environments and extreme natural conditions? HYDRANTULA structures are conceived as long-life infrastructure elements that are repairable, maintainable and, where necessary, replaceable. Their assembly does not rely on complex offshore machinery or highly specialised marine crews, which simplifies long-term operation and lifecycle management.
04
...modular like a construction set
What if a limited set of modular elements could address up to 90% of typical marine construction needs? By combining more than 40 standardised structural fittings, HYDRANTULA enables the creation of a wide variety of spatial configurations. The system works conceptually like a construction set, allowing designers and engineers to adapt structures to site-specific requirements without developing bespoke solutions for every project.
So, what is HYDRANTULA?
HYDRANTULA is a modular technology for the creation of permanent 3D marine and coastal structures based on reinforced concrete formed within a non-removable structural framework. The technology is intended for use in underwater and tidal-zone environments where traditional piling, massive concrete works or extensive offshore construction are constrained by cost, logistics or environmental considerations.
The core concept of HYDRANTULA is the separation of structural assembly from marine installation. Structural frameworks are assembled primarily on land using standardised components, then transferred to the marine site for installation and structural completion. Once in place, the framework becomes an integral part of the final structure, contributing to durability, corrosion protection and long-term performance.
HYDRANTULA is not a single product but a construction system. Its modular nature allows the same technological platform to be adapted across multiple applications, geometries and load scenarios, while maintaining consistent construction logic and predictable performance.
HYDRANTULA is designed for a broad range of coastal and marine applications, particularly in shallow and mid-depth waters.
Typical use cases include:
-
Private and public piers, jetties and access platforms
-
Nearshore beaches and waterfront developments
-
Small and medium-scale marine terminals and berthing structures
-
Coastal protection systems and wave-attenuation structures
-
Expansion and stabilization of reclaimed or artificial land
-
Flood-protection and shoreline reinforcement infrastructure
The modular character of the system allows structures to be scaled from small private installations to large civil infrastructure projects. HYDRANTULA can be deployed as a standalone structural solution or integrated into hybrid coastal systems combining engineered and nature-based elements.

Smart Solutions
Designed to integrate,
not to displace
HYDRANTULA is conceived as a construction technology that integrates into the marine environment rather than displacing it. The system avoids massive solid barriers and instead relies on spatial, permeable structural forms that allow water movement and natural sediment dynamics to continue around and through the structure. This approach reduces the likelihood of secondary erosion effects and supports long-term stability of surrounding seabed conditions.
Material neutrality and ecological compatibility
The primary structural framework of HYDRANTULA is based on materials widely used in marine and offshore environments for their chemical stability and long-term durability. These materials are considered environmentally inert under normal marine conditions and do not release harmful substances into the water column. As a result, they do not alter water chemistry or interfere with biological processes in the surrounding environment.
Carbon footprint considerations by design
HYDRANTULA is designed with a strong emphasis on carbon efficiency across the construction lifecycle. The technology reduces reliance on heavy offshore equipment, the need for prolonged marine operations, and the energy intensity of construction processes. By shifting the majority of construction activities to land and minimising offshore work, overall fuel consumption and associated emissions are reduced compared to conventional marine construction approaches.
Environmental performance, ecological integration, and carbon footprint outcomes depend on project-specific conditions, design decisions, materials, logistics, and construction practices. The information presented here describes the general environmental characteristics of the technology and does not constitute a guarantee of specific ecological or carbon performance outcomes for any individual project.
