Initial design
With our conceptual or initial design services we assist you in finding the best vessel solution – offering support in analysing the advantages and disadvantages of different options.
The detail level of initial design suitable to bid tendering to yards and to allow sub-contractors to quote equipment.
Technical documentation

Basic design
After contract signing, we dive into the basic design phase – creating the key plans and main documents needed for approval from the classification societies. These mainly consist of Autocad drawings.
Structural drawings
- Profile and plan
- Main sections
- Shell expansion
- Main foundations
Arrangement drawings
- Internal and external arrangement
- Antenna arrangement
- Freeboard plan
- Fields of vision
- Insulation plan
- Other system arrangements
Vessel system layouts
- Cooling system
- Cargo systems
- Electrical system
- HVAC system
- Other system diagrams
Final documentation
- Inclining test
- Intact and damage final stability check
- Manuals

Detail design
During the detail design phase, the vessel is progressively developed with the addition of details. This includes the preparation of production information.
3D modelling
Piping and machinery
- Isometrics
- Coordination drawings
- Penetration drawings
- Installation drawings
Steel structure
- Foundations
- Block and section plan
Detailed drawings
- Cable diagrams
- Outfitting drawings
- Steel details

Modifications & upgrades
To vessels already in operation, we offer flexible design and engineering services for the entire life cycle. Whether we are talking simple modifications, retrofits, or complete vessel conversions, we scale our project scope accordingly.
Examples
- Hybrids and clean alternative fuels
- Lengthening
- Widening for capacity increase
- Integration of new equipment
- Upgrades of propulsion and machinery systems
- Shipyard design support
Our design services can be complemented by hydrodynamic engineering services, including computational fluid dynamics calculations (CFD), seakeeping calculations, DP-related calculations, and propulsion system optimisation.
