Join forces with the expert naval architects of SARC

Our naval architects are heavily involved with the design of vessels and floating structures of all shapes and sizes, on a daily basis. Whether you just need some advice, or you’re looking to outsource your design calculations: our team is ready to help.


What can we do for you?


Intact stability

Intact stability calculations for all types of vessels and floating structures, including tankers, inland waterway vessels, (split) hopper dredgers, jack-up platforms, and crane barges.

Damage stability

Deterministic or probabilistic damage stability calculations for all types of vessels, including hopper dredgers.

Grain stability

Grain stability calculations in accordance with the Grain Code.


Tank sounding

Calculations based on tank sounding measurements.

Vessel optimizations

Optimization of existing cargo vessels with respect to probabilistic damage stability. Trim optimizations to minimize resistance. Determining a vessel’s expected power and speed.

Comparative studies

Comparative studies on a vessel’s structural integrity and damage stability.

Design & testing

Vessel design

Design of vessels of various types, including inland waterway passenger vessels and float-on/float-off submersible vessels.

Hull form fairing

Vessel fairing and shell plate expansions of all types of vessels. Adjust hull forms to match developable shell plates or include templates for curved shell plates.


Measure an existing hull form by means of photogrammetry.

Production tests

Lightweight checks and inclining tests.

Other calculations

Structural integrity

Calculations of structural strength properties, including longitudinal strength.

Floating structures

Calculation of floatability, forces and moments of floating structures, including jack-up platforms, floating motorway tunnel elements, floating swimming pools, and moveable flood barriers.


Seakeeping calculations of offshore transports.

Special cases

Some vessels require additional non-standard calculations we may be able to offer. For example, we offer ballast calculations for crane barges, and stability calculations for ‘estuary traffic’ inland waterway vessels.
