What we are good at.

Capabilities / 09

01 / 09

3D Geometrical Modelling

Production-grade CAD geometry for structural, hydrodynamic and visualisation downstream. Watertight surfaces ready for class-society review.

02 / 09

Naval Architecture & Offshore Engineering Design

From small craft to major offshore installations. Stability, structural and intact/damage analysis to international standards.

03 / 09

Hydrodynamic Optimisation

CFD-driven hull, appendage and propulsor refinement, reducing fuel burn and emissions in real operating conditions.

04 / 09

Ship Manoeuvrability Prediction

Time-domain simulation and dynamic models to forecast vessel behaviour and assess autonomous-manoeuvring envelopes inside ports.

05 / 09

Mooring System Design

Catenary, taut-leg and hybrid systems for floating renewables, aquaculture and offshore platforms. Environmental loads to anchor sizing.

06 / 09

Vessel Conversion Engineering

Remotorisation, repurposing and capacity uplift, from minor modifications to full conversions, in compliance with current regulations.

07 / 09

Supervision of New Constructions

Independent oversight of yards and contractors. Quality control, technical compliance and acceptance testing through delivery.

08 / 09

Maritime Decarbonisation

GHG-reduction pathways for vessels and offshore assets. Alternative fuels, energy efficiency, and FuelEU Maritime / IMO 2050 compliance.

09 / 09

Digitalisation & Digital Twin

Digital-twin development, data-driven performance monitoring, and digitalisation strategy for fleets and offshore operations.

✦ Trusted by operators

“KDS Offshore executed the engineering project for the remotorisation and increased capacity of our "Belize I" catamaran with competence, professionalism, and dedication, successfully meeting all established deadlines. We were very impressed with the technical lead, Eng. Sérgio Ribeiro e Silva.”
