Propulsion system performance suffers when responsibility is fragmented. We provide end-to-end engineering ownership of vessel propulsion systems, from concept through operation, ensuring predictable performance and reliability.
Every propulsion challenge is different. There is no off-the-shelf solution.
We identify where engineering depth creates measurable financial impact, grounded in your actual operating profile—not generic assumptions.
Performance targets aligned to your duty cycle, not catalogue specs
Architecture choices that reduce interface risk and downstream rework
Advanced simulation where it materially changes design outcomes and cost
Every project begins with a tailored entry path, depending on your vessel type, objectives, and the insights you need. Across all paths, we apply data-driven analysis, engineering precision, and close partnership to deliver solutions that enhance performance, efficiency, and operational clarity.
A practical entry point to focus propulsion investments where they matter most.
The Initial Fleet Analysis is a structured, engineering-led assessment of your existing vessels and their operational context. It is designed to identify where propulsion-related decisions have the greatest impact on efficiency, reliability, and lifecycle cost, helping you build clarity before committing to detailed engineering work or capital investment.
What we look at
We examine operational profiles to understand how the vessels are actually used in service, rather than how they were originally specified.
We review installed propulsion architectures and the critical interfaces between them.
We assess performance and reliability indicators and known operational issues. We evaluate upgrade and retrofit potential to identify where targeted changes could deliver measurable improvements.
What you get
You receive a clear technical perspective on where performance is lost, inefficiencies are introduced, or operational risk is created within the propulsion system.
Improvement areas are prioritized and linked directly to their operational and financial impact, providing a practical basis for decision-making.
The result is a fact-based foundation for defining next steps — or, where appropriate, for making a confident decision not to proceed.
How it works
We start with the data you already have and fill gaps pragmatically, focusing on insight and relevance rather than perfect completeness at the beginning. Step by step we gain objective clarity that supports a technical and commercial decisions.
What we look at
We define how the vessel will operate in service, based on its operational purpose, cargo and payload variability, route definition, seasonal weather and environmental exposure, station-keeping and redundancy philosophy. We derive operating modes, load distributions, and peak demand scenarios across transit, DP, maneuvering, hotel load, and exceptional operating cases.
Mission drivers such as emissions targets, fuel strategy, availability requirements, and foreseeable operational growth are assessed and translated into governing boundary conditions for propulsion and power system architecture, propulsor selection, control strategy, and energy management.
Where input data is incomplete or uncertain, we apply targeted assumptions and sensitivity analyses to ensure the resulting design space is robust across the expected operating envelope.
What you get
You receive a quantified operational baseline that can be used directly for parameter studies, concept screening, and system optimisation. Deliverables typically include duty cycle definitions, load envelopes by operating mode, propulsion-relevant performance targets, reserve margins, and a transparent set of assumptions and sensitivities.
This operational profile becomes the reference framework for downstream phases—supporting detailed design and specification development, performance verification during delivery, and comparison with measured data during in-service operation.
How it works
We start from the operational intent and the information available. This is structured into an operational model, key gaps are identified, and closed pragmatically through engineering judgement and sensitivity checks.
Step by step, we build a defensible, traceable operational profile that enables objective trade-offs, reduces iteration later in the project, and maintains continuity from early concept decisions through optimisation, detailed engineering, delivery, and lifecycle performance monitoring.
A focused entry point for vessels where standard solutions and assumptions do not apply.
The Special Purpose Vessel Assessment is an engineering-led evaluation of feasibility, capability, and propulsion-system implications for non-standard vessels and demanding missions. It establishes technical clarity early—before resources are committed to design paths that may not meet operational requirements or technical constraints.
What we look at
We assess mission intent, operational constraints, and performance drivers that define the vessel as special purpose—such as extreme or transient duty cycles, unconventional propulsors, advanced control requirements, novel operating environments, or atypical redundancy and availability needs.
We explore a broad solution space, evaluating architecture options and key parameter ranges to identify feasibility limits and the true drivers of performance, efficiency, and risk. Where conventional approaches fall short, we define what must be engineered differently across architecture, controls, integration, or verification.
What you get
You receive an objective technical view of feasibility, key risks, and viable architecture directions, including prioritized parameters and the critical design questions that must be resolved next.
You gain clarity on what can be specified with confidence, what must remain flexible, and where further development is required to achieve reliable in-service performance.
How it works
We start with a structured technical intake, then perform a broad parameter exploration and progressively refine the solution space through iteration and targeted modelling. Where needed, we develop tailored analysis methods to ensure decision quality matches the novelty and complexity of the vessel.

Despite us being a technology-driven business, we will prefer human contact over automated messages.
Our goal is to combine technological innovations with tradition. Same goes for communication. Every ship is different, so is every request. That's why we've opted out of an automated message process and chose to hear from you directly via e-mail.
