About the office

Founded
in Lisbon.
Quietly opinionated.

KDS Offshore was founded in 2016 by naval engineers from Instituto Superior Técnico, University of Lisbon. We are a partnership (not a consultancy chain) and we have stayed deliberately small so that the principals are the ones doing the engineering you pay for.

Principles · 04

How we behave.

NO. 01

No work we cannot stand behind

If the brief is wrong, we say so. If the budget is too small, we say so. If a competitor is better placed, we say so. The reputation we are building is worth more than any single fee.

NO. 02

Principals do the engineering

You hire us, you get us. Junior engineers support, but the model, the report, and the recommendation come from a named principal.

NO. 03

Write everything down

Every assumption, every input, every result is documented. Six months later, when the operator has a new question, we can answer it because the model is still alive.

NO. 04

Make it less polluting

Wherever there is a choice between a faster hull and a cleaner hull, we present both. We believe the maritime sector is going to decarbonise.

Ten years.

✦ Founding partner
"We came out of IST with a thesis: that careful engineering, calmly applied, can make a measurable difference. Ten years and one hundred-plus projects later, we still believe it, and the data backs us up."
