Mooring-system acceptance
Five conservation areas need five buoy-acceptance records
Zanzibar Marine and Diving Services signed the USD 266,877.81 supply-and-installation contract for demarcation, mooring and marker buoys across five marine conservation areas on 12 March 2026. The procurement plan carries a 24 May 2026 planned completion and still marks the package Signed. No cited source provides buoy counts, component specifications, installation records, tests or location-level acceptance.
The planned completion date passed without a five-area handover matrix
Contract 1883881 controls Zanzibar Marine and Diving Services' role, 12 March 2026 signature, USD 266,877.81 amount and direct-selection route. The May 2026 procurement plan controls the five-area package title, USD 300,000 estimate, Signed status and 24 May 2026 planned completion. P179969 metadata controls the wider programme, not package closeout. No cited record proves installed quantities, testing, acceptance or lower tiers as of 5 August 2026.
Five locations lack disclosed installation and acceptance records
Buoy work is a compact contract with a long technical evidence chain. Each location needs survey coordinates, seabed confirmation, anchor or sinker selection, chain and connector certificates, controlled installation, freeboard and swing checks, marking verification and acceptance. Missing one step can leave a buoy visibly present but technically unproven.
Evidence conclusion
Acceptance should follow components, coordinates and installed condition
Contract 1883881 establishes the named specialist supplier, amount and direct-selection route. It does not disclose whether the five-area title represents identical systems or different mixes of demarcation, mooring and marker buoys. Completion should be assessed through a location matrix for MBCA, MIMCA, PECCA, CHABAMCA and TUMCA, supported by buoy schedules, manufacturer and material certificates, anchor and chain details, installation coordinates, diver or remote verification, test records, owner acceptance and maintenance responsibility.
