About Aquarian
A Tanzanian marine contractor, built around the lakes
Aquarian Project Solutions Company Limited is a marine engineering and project delivery company registered in Tanzania and headquartered in Mwanza, on the southern shore of Lake Victoria.
We were formed to serve a specific need. Tanzania's inland waterways carry fuel, cargo, passengers and fish across three of the largest lakes in the world, and the vessels doing that work need survey, steel repair, engineering and coatings from contractors who can reach them. Much of that capability has historically sat at the coast, hundreds of kilometres and several weeks away from a vessel that is losing money every day it sits idle.
We built the alternative on the lake itself. Our crews mobilise from Mwanza to wherever the work is — Kigoma Terminal Port, Bulombora, Ukerewe, Bunda, or a berth on Lake Victoria — with the trades, the tools and the materials to complete the scope rather than to assess it and come back.
Our approach
What we bring to a contract
Range under one roof
Naval architecture, survey, welding and fabrication, engine and machinery work, piping, electrical, sandblasting and coatings, scaffolding, skilled labour and materials supply. A vessel rehabilitation typically needs most of that list. We would rather deliver it than coordinate it.
Technical leadership that signs its name
Our technical direction sits with a registered Professional Engineer. On marine structural work, that is the difference between a repair that satisfies a surveyor and one that has to be done twice.
Local knowledge that shortens schedules
We know which yards have a slipway free, how long steel takes to reach Kigoma, and which weeks on the lake you do not want to be committed to open-water work. That knowledge usually determines whether a project finishes on time.
Compliance that holds up
We are incorporated in Tanzania, licensed for the marine work we perform, tax-registered and a contributing NSSF employer. Our documentation is complete and current, and we can produce it on request for any tender or pre-qualification.
Our mission
To keep Tanzania's vessels and marine infrastructure safely in service — by delivering engineering, fabrication and survey work of a standard our clients can rely on without checking, and by building the local technical capability the sector needs to sustain itself.
Our vision
To be the marine engineering contractor of choice across Tanzania's Great Lakes and the wider East African region: the company an owner calls first when a vessel is out of service and there is no margin for a job done twice.
What we hold to
Five values the work actually demands
Safety without exception
Marine work is unforgiving — confined spaces, hot work, height, and open water, often at once. No schedule, no client and no cost pressure moves the standard. Every crew goes home.
Quality that survives inspection
The test of our work is not whether it looks finished. It is whether it passes a surveyor, an insurer and another five years on the water.
Integrity in the quote
We price what we can see and we tell you what we cannot. If a scope is going to grow, we would rather say so at tender than discover it together at 60 percent completion.
Skill built locally
We hire and train Tanzanian tradespeople. Every project is an opportunity to leave more welding, survey and engineering capability in the country than we found.
Answering when it matters
A vessel out of service is a business losing money. We respond quickly, mobilise fast, and stay reachable through the job.
