Conversion Support
Adapting existing vessels to new requirements, so they can take on a new role, new equipment or changing operational demands.
When those changes are needed, DEKC delivers the design and engineering to make them work. We start by understanding the vessel, the intended operation and the practical constraints, then assess how the required changes fit into the existing design. Our multidisciplinary approach covers the full impact of a conversion, from stability, strength and weight to systems, machinery, piping and outfitting. Where existing information is limited, surveys, laser scanning and 3D modelling provide an accurate basis for the engineering.
We develop the solution from feasibility and concept design through to class documentation, detailed engineering and production information. Whether it is a major refit, new equipment, alternative propulsion or a smaller modification, our focus is on making the conversion technically sound, practical to execute and fit for purpose.
Recent conversions include the eSAIL installation on Fluvius Tavy for Amasus, the crane upgrade of the jack-up vessel Aeolus for Van Oord, the conversion of Hartman Baltic into the fish feed carrier Eidsvaag Omega and the cruise ship AidaMira for Carnival Maritime.
Conversion feasibility
What the vessel can take, what class and flag will accept, and what the conversion really costs.
Before starting a conversion, we assess whether the proposed changes are technically feasible and what they mean for the vessel. By considering stability, strength, weight, space, systems and class requirements at an early stage, we identify constraints and possible solutions before major design decisions are made.
Lengthenings and rebuilds
New sections, repurposing and capacity changes, engineered on a full 3D model of the existing ship.
For vessel lengthenings and major rebuilds, we engineer the integration of new sections, structures and systems into the existing ship. From stability and structural integrity to systems, weight and class requirements, we consider the vessel as a whole and develop the design through to production-ready engineering.
Check-ups and surveys
An independent read on the state of a vessel and the steps to keep it in service, including class and flag surveys.
Onboard surveys and technical assessments provide the basis for understanding the condition of an existing vessel and identifying where action is required. DEKC combines practical inspection with engineering expertise to assess structural and technical issues and define the modifications, repairs or further investigations needed to keep the vessel in service. We also support class and flag-related surveys and follow-up engineering.
Proof on real vessels
Conversion engineering for the eSAIL installation on Fluvius Tavy
DEKC was responsible for the engineering of the vessel conversion required to integrate the eSAIL® into the existing ship. Our scope included the structural modifications, foundation design and all engineering required to safely incorporate the sail into the vessel while meeting class requirements. Close cooperation with Amasus, bound4blue, the classification society and Astander Shipyard ensured that the engineering supported an efficient installation process.
The project demonstrates how existing vessels can be adapted to support the maritime energy transition. By combining detailed structural engineering with practical shipbuilding knowledge, DEKC helped create a solution that integrates new technology into an operational vessel while minimising disruption and maintaining confidence in the vessel’s structural integrity.
