Marine contractor · Mwanza, Tanzania
Marine engineering built for Tanzania's lakes, coast and ports
We rehabilitate vessels, survey and inspect them, fabricate the steel that holds them together, and manage the projects that keep them working. From our base in Mwanza, our crews work across Lake Victoria and Lake Tanganyika, out to the Indian Ocean coast, and the industrial sites in between.
Licensed and registered
Marine vessel fabrication (Class III) and civil & building works (Class VI).
Mwanza-based, wide reach
Crews mobilised across the lakes, out to the coast and inland sites.
Chartered technical leadership
Directed by a registered Professional Engineer.
Full-scope delivery
Survey, steelwork, engineering, coatings and supply under one contract.
What we do
One contractor, from survey to sea trial
Most marine work in Tanzania is split across several suppliers — one to survey, another to weld, a third to source the steel, a fourth to supply the crew. Every handover is a delay, and every delay costs a vessel its earning days.
Aquarian was built to close those gaps. We hold survey, fabrication, engineering, coatings, labour and materials supply in-house — a single scope, a single schedule and a single point of accountability.

Our record is not a list of intentions. It is tankers, pontoons, fishing fleets and port channels that were out of service and are now operating.

How we work
Four commitments we hold to on every contract
We survey before we quote.
A price built on assumptions becomes a variation order later. Where the scope allows it, we inspect first and quote against what is actually there.
We work to marine standards.
Hull steel, coatings and machinery on a working vessel face loads and corrosion that shore-based work never sees. Our specifications reflect that.
Nobody gets hurt.
Every crew works in full PPE, to a method statement, with a competent person supervising. The standard does not move.
We hand over documented.
Photographs, measurements, materials certificates and as-built notes — a file you can hand to a class surveyor, insurer or auditor.
Tell us what needs fixing
Send us the vessel, the site or the scope and we will tell you honestly whether it is work we should be doing. If it is not, we will usually know who should.
