Project anatomy

Contract scope and delivery roles

Client / authority
Ministry of Blue Economy and Fisheries Zanzibar under the World Bank-financed TASFAM project
Delivery parties
Zanzibar Marine and Diving Services - direct-selected supplier and installer under TZ-MBEF-532089-GO-DIR, Buoy manufacturer, chain and sinker suppliers, surveyor, vessel provider, diving subcontractors and acceptance authority - not identified in the cited award record
Contract route
The procurement plan identifies a post-review, direct-national Direct Selection goods package with a USD 300,000 estimate. The contract API records the later committed supplier amount of USD 266,877.81 and 12 March 2026 signature. The source sequence includes a later no-objection metadata date and should not be converted into an installation milestone.
Execution window
The procurement plan lists 24 May 2026 as the planned contract-completion date. That date has passed without an actual completion entry in the cited plan or separate acceptance evidence. TASFAM remains active to 30 June 2030, but the programme closing date does not determine this package's delivery status.
Works package
The award title covers supply and installation of demarcation, mooring and marker buoys across MBCA, MIMCA, PECCA, CHABAMCA and TUMCA. Public records do not disclose the number or mix of buoys, service loads, materials, colours, lights, anchors, sinkers, chains, swivels, shackles, coordinates, installation tolerances, warranties or maintenance obligations.
Marine interfaces
The work requires location survey, protected-area access, bathymetry and seabed confirmation, vessel positioning, lifting, chain and anchor handling, diving or remotely verified placement, buoy freeboard and swing-radius checks, navigation marking and environmental controls. Evidence is needed separately for each conservation area because one signed contract does not prove five accepted installations.
Commercial evidence boundary
The USD 266,877.81 supplier amount is USD 33,122.19 below the procurement-plan estimate, but this is a tender-baseline difference rather than evidence of savings or final account. Quantities, taxes, variations, retention, defects obligations and maintenance support remain undisclosed.
