Ingeniat Estudios y Proyectos SL is a Spanish engineering and project management consultancy specialising in the maritime and offshore energy industries. Founded in 2007 and based in Spain, the firm provides technical services across the full project lifecycle — from early-stage feasibility and concept design through detailed engineering, regulatory compliance, and commissioning support.
The firm operates at the intersection of three disciplines that are increasingly inseparable in modern marine operations: engineering design, environmental compliance, and applied digitalisation. This combination allows Ingeniat to address problems that span technical, regulatory, and data dimensions simultaneously, rather than treating each in isolation.
Ingeniat works directly with shipowners, operators, managers, and yards across the maritime sector, as well as with drilling contractors and offshore operators requiring specialist mechanical, process, and structural engineering input. The firm’s client base reflects the breadth of its technical capabilities: from bulk carriers and tankers navigating CII rating requirements, to offshore drilling units requiring bespoke equipment design and hazardous area engineering.
Ingeniat’s services are organised into five main practice areas, each addressing a distinct set of technical and commercial challenges facing maritime and offshore clients.
Green Ship Solutions
Beyond energy efficiency in the conventional sense, a growing range of onboard waste streams and environmental systems require engineering solutions that meet regulatory requirements while delivering operational value. Ingeniat designs integrated systems that address these challenges at the process level.
- Onboard sludge-to-energy systems, converting fuel oil purifier residues through mechanical dewatering, controlled incineration, and waste heat recovery into a measurable contribution to the vessel’s steam balance
- Food waste maceration and thermal stabilisation systems, processing galley waste through size reduction, pasteurisation, and biological stabilisation for compliant handling under MARPOL Annex IV and V
- Thermal hydrolysis systems for onboard waste treatment, applying pressure-temperature hydrolysis to complex organic waste streams
- Marine incinerator and thermal waste treatment device engineering, covering equipment selection, process integration, refractory design, CEMS specification, and MEPC.76(40) compliance documentation
- Ballast water management system advisory and engineering support, covering technology selection, retrofit engineering, and D-2 standard compliance verification
- Exhaust gas cleaning system (scrubber) engineering, including open-loop, closed-loop, and hybrid configurations, wash water treatment, and MARPOL Annex VI compliance documentation
- Vacuum-based collection system design for grey water and sewage, covering pipeline sizing, tank arrangement, and MARPOL Annex IV compliance
Drilling Solutions
Ingeniat provides specialist engineering services to the offshore drilling sector, where the combination of hazardous process environments, structural demands, and bespoke equipment requirements calls for engineering capability that extends beyond standard marine practice.
- Drill cuttings handling system design, covering transfer, storage, and discharge equipment for both water-based and oil-based mud cuttings
- Drill cuttings reinjection system engineering, providing a zero-discharge solution for oil-contaminated cuttings through downhole slurry injection
- Drilling mud treatment, mixing, and cooling system design, including degasser, shale shaker, centrifuge, and hydrocyclone circuit engineering
- Chemical storage skid design and layout, including bunded containment, chemical compatibility assessment, and hazardous area classification
- Filtration and separation system engineering for drilling fluid treatment
- Local equipment rooms and driller cabins: structural design, HVAC, and marine-rated electrical systems for rig-mounted control environments
- Offshore container design and certification to DNV 2.7-1 / EN 12079 standards
- Bespoke mechanical and structural design for non-standard drilling equipment and interface structures
Regulatory Compliance
The maritime regulatory environment has undergone a structural acceleration since 2023. The entry into force of CII operational carbon ratings, the expansion of EU ETS to shipping, the FuelEU Maritime greenhouse gas intensity requirements, and the progressive tightening of MARPOL Annex VI obligations have created a compliance landscape that demands continuous technical engagement rather than periodic documentation review.
Ingeniat’s compliance services cover the instruments that govern this landscape:
- CII gap analysis and corrective action plan development, including attained CII calculation, required CII benchmarking, rating trajectory modelling, and the preparation of Corrective Action Plans for vessels rated D or E
- EEXI technical compliance services, covering Engine Power Limitation assessments, shaft power limitation design, and the engineering documentation required for class and flag approval
- EU ETS monitoring, reporting, and verification support, including MRV data quality assurance and allowance liability assessment
- FuelEU Maritime compliance advisory, addressing GHG intensity methodology and the implications of fuel switching across the vessel’s operating profile
- MARPOL Annex VI ECA zone compliance advisory, covering fuel switching procedures, documentation, and operational controls for Sulphur Emission Control Area transits
- Vessel energy efficiency audits and SEEMP development across all three Parts, including annual review, DCS methodology assessment, and integration with fleet performance monitoring systems
- MARPOL Garbage Record Book advisory, covering Annex V categorisation, recording obligations, and port state control documentation readiness
- IMO Net-Zero 2050 decarbonisation strategy development, providing shipowners and managers with structured frameworks for long-term fleet transition planning aligned with IMO trajectory requirements
Energy Efficiency
Reducing fuel consumption and associated emissions requires engineering intervention, not only operational adjustment. Ingeniat designs and specifies the onboard systems through which thermal energy is recovered, redirected, and utilised more completely across the vessel’s heat and power balance.
- Waste heat recovery unit design and integration, capturing exhaust gas and jacket water energy for conversion to steam or hot water for vessel consumers
- Steam condensate recovery system engineering, minimising boiler feedwater and chemical treatment consumption while recovering heat from condensate return circuits
- Jacket water-driven seawater desalination system design, utilising low-grade engine cooling heat to produce fresh water and reduce evaporator energy demand
- Energy efficiency optimisation studies, identifying vessel-specific opportunities across hull performance, propulsion, auxiliary systems, and heat management
Digitalization
Engineering design and regulatory compliance increasingly depend on the ability to process, model, and interpret large datasets — whether from vessel performance monitoring systems, classification society databases, or operational logs. Ingeniat applies digital and computational methods to problems that cannot be adequately addressed by conventional engineering analysis alone.
- Digital twin development for vessel systems, enabling real-time performance comparison against calibrated models and early identification of degradation
- Finite element analysis for structural assessment of marine and offshore components, including fatigue life evaluation and weld assessment
- Intelligent simulation for process and system modelling, supporting equipment sizing, control system design, and what-if analysis
- Data analysis services for vessel performance, fuel consumption, and emissions datasets, supporting both internal management decisions and external regulatory reporting
- Language model fine-tuning for domain-specific maritime and engineering applications
- Maritime compliance dashboard development, providing fleet-level visibility of CII ratings, EU ETS exposure, FuelEU GHG intensity, and other regulatory metrics within a unified monitoring environment
How We Work
Ingeniat operates as a specialist consultancy rather than a large-scale engineering house. This means that clients work directly with engineers who hold subject matter expertise in the relevant domain, rather than with account managers who coordinate work performed elsewhere. It also means that project scope is defined around the client’s actual problem, not shaped to fit a standard service package.
Engagement typically follows a structured sequence: a feasibility or gap assessment establishes the technical and regulatory baseline; concept or schematic design defines the solution space; detailed engineering produces the deliverables required for procurement, classification, or installation; and commissioning and start-up support ensures that the designed system performs as intended in service. Not every project requires all phases — clients may engage Ingeniat at any point in this sequence, including for review and advisory work on designs or plans developed by others.
Where a project spans multiple practice areas — for example, a vessel requiring both sludge-to-energy system design and CII compliance advisory — Ingeniat manages the technical interfaces between disciplines rather than treating each as a separate engagement. This integration is particularly valuable in cases where engineering decisions in one domain have direct regulatory consequences in another, as is increasingly the case as environmental regulation becomes more technically granular.
Sustainability Commitment
Ingeniat’s work is premised on the view that the transition of the maritime industry to lower environmental impact is an engineering problem as much as a policy or commercial one. Regulations establish the targets; engineering determines whether vessels can meet them in practice, at what cost, and on what timeline.
The firm’s service portfolio is structured to address both the compliance dimension of this transition — ensuring that vessels meet current and forthcoming regulatory requirements — and the engineering dimension, designing the systems through which fuel consumption, emissions, and waste are reduced at source. These two dimensions are treated as inseparable: compliance without engineering improvement produces documentation without performance gain; engineering without compliance integration produces systems that may not satisfy the regulatory frameworks under which they must operate.
Ingeniat believes that innovation and responsibility go hand in hand, and is committed to engineering a future where sustainability is the standard, not the exception — and to helping clients navigate the transition to a low-carbon future with technical rigour rather than generic commitments.
