Today's decisions matter more than ever.
The maritime industry is becoming more complex than ever. Alternative fuels, digitalisation, changing regulations and new operating models have made every design decision more important than ever. At HAV Design, we combine maritime engineering, operational insight and advanced technology to help customers reduce uncertainty and optimise lifetime performance.

Performance
Effective use of available deck space
Effective use of available deck space
A working deck and equipment arrangement developed around the intended operation.
Operation-driven deck layout
Operation-driven deck layout
Equipment positioning, working areas and deck logistics are planned together to maximise usable working space and support efficient workflows.
Energy-
efficient operations
Energy-efficient operations
Hull, propulsion and energy systems can be optimised around the vessel´s intended operating profile
Efficiency where the vessel spends its time
Efficiency where the vessel spends its time
Hull, propulsion, and power systems are optimised for the operating modes in which the vessel is expected to spend most of its working time, rather than around a single design condition.
Performance does not end at delivery
Operational needs, technology and requirements change throughout a vessel’s lifetime.
HAV Design applies its design and engineering expertise to help customers evaluate, adapt and improve their vessels as those needs change.


Making performance measurable before decisions are made
Ocean Lab uses simulation, analysis and data to explore how design choices affect vessel performance.
It provides a stronger basis for comparing alternatives, reducing uncertainty and making informed design decisions.
Different markets.
One common objective.
Better performance.
One common objective.
Every market has unique challenges. Our role is to understand
them and create solutions that maximise operational and
commercial performance.
Supporting fish welfare, operational efficiency, and long-term value.
Supporting the transition with flexible and future-ready vessel solutions.
Designing vessels that remain competitive throughout changing market conditions.
Designing tailored vessel solutions for unique operational requirements.
We help customers optimise, adapt and future-proof their vessels throughout their operational lifetime.

Confident vessel design decisions
HAV Ocean LAB reduces uncertainty in early-stage vessel design by turning complex trade-offs into validated insight.
• Lower technical risk
• Faster concept development
• Higher energy efficiency
• Longer vessel lifetime
• More confident investment decisions

Performance
By Design.
HAV Ocean LAB creates digital twins of vessels and sea areas to simulate and compare technology solutions, helping you identify the optimal overall concept before you build.
