Retrofit Design & Engineering

Rapid turnaround retrofit engineering 

Our retrofit engineering design services have been tailored to ensure efficient delivery with the highest level of quality.

Advanced Retrofit Design with 3D Point Clouds

Whether it be ballast water treatment, exhaust gas scrubbers or replacement sewage treatment plants, our unique combination of advanced engineering software and 3D point clouds ensures we design at the highest level of accuracy.

Our intelligent software enables automatic output of highly accurate material take-offs, pipework fabrication isometrics and structural detailing.

Clash detection is also undertaken semi-automatically, with comprehensive clash reports featuring as part of our standard retrofit engineering deliverables.


Cleanship has experience of over 250 retrofit engineering design projects to date, covering almost all vessel types and sizes.

Designing for Pre-Fabrication & Installation

With highly accurate, as-built, 3D point clouds as the basis of our designs, we can engineer any retrofit to suit pre-fabrication of pipework and steelwork – enabling a quick and efficient retrofit installation – and minimising cost.

Tieing in with our turnkey retrofit services, we can also offer fabrication or full turnkey retrofit installation services, worldwide.


Cleanship Retrofit Engineering Process

Vessel Survey & 3D Scan
An experience Cleanship 3D surveyor will meet your vessel at a location and time which best fits with your trading patterns, to undertake a comprehensive vessel survey & 3D laser scan.
Feasibility Study
Where required, our engineering team will undertake a detailed feasibility study of the proposed retrofit, examining all aspects of the technical and, if required, economic feasibility of the proposed retrofit installation.
Detailed Retrofit Engineering
Our team will undertake the full retrofit engineering design for the proposed retrofit project, including all aspects of structural, pipework, electrical, HVAC design, as well as Class Approvals. Deliverables include a comprehensive installation drawing package.
Retrofit Installation Supervision
Our local, experienced, site teams can attend and oversee the retrofit installation project, either during drydocking or as part of a riding squad, to ensure the installation is carried out in accordance with the drawing package, and minimise any potential re-work.
