Bunkering Guide for Mombasa

Geography & Terminals

• Strategic Location: Mombasa is the primary gateway to East and Central Africa, situated on a major international shipping lane, making it a convenient bunkering hub.
• Harbour areas: Kilindini Harbour, Port Reitz channel, and various container, oil, and product terminals.
• Alongside deliveries: Typically by truck-to-ship or barge alongside at permitted berths, subject to terminal approval.
• OPL (Off Port Limits): Barge deliveries are a common option for vessels looking to avoid port call costs.

Permissions & Clearances

• Local Agent is Key: For ship/vessel operators, appointing a reputable local shipping agent is essential for navigating port formalities smoothly.
• Authorities: Kenya Ports Authority (KPA), Kenya Maritime Authority (KMA), and Port Health.
• Documents required: A formal Request to Bunker, P&I/Insurance details, and SDS. It is recommended to review the supplier’s intended Bunker Delivery Note (BDN) format for MARPOL compliance.
• Lead Time: It is advisable to provide at least 48 hours’ notice for all bunkering nominations to ensure timely approvals.

Operational Procedure

OPL bunkering in Mombasa is performed by barge at designated rendezvous points or within specified anchorage areas. This option is often chosen by vessels on international routes to save time and port-related costs. Coordination is managed between the vessel’s agent, the bunker supplier, and port control to ensure a safe and timely operation.

Safety & Weather

Offshore operations are highly dependent on weather conditions. Swell and wind can impact the safety of mooring the bunker barge alongside. The Master of both the receiving vessel and the bunker barge retain the right to postpone or suspend operations if conditions are deemed unsafe. Having an independent surveyor on board provides an experienced third party to help assess these risks.

At-Berth Bunkering

This is the most common method for vessels already alongside for cargo operations. Bunkers are delivered either by road tanker or by a bunker barge. This requires close coordination with the Kenya Ports Authority (KPA) and the terminal operator. Truck deliveries are suitable for smaller lubricant/ MGO stems, while barges are used for larger VLSFO & MGO deliveries.

Shore Terminal Operations (SOT)

For larger stems, direct shore-to-ship bunkering can take place at the Shimanzi Oil Terminal (SOT). This facility is also used for backloading (loading bunkers onto a barge for export) and is the primary supply point for barges servicing vessels in-port and offshore. Operations at SOT require careful scheduling through your agent.

Fresh Water Bunkering

Fresh water supply in Mombasa is handled flexibly to accommodate vessels both at berth and at anchorage. For vessels alongside, potable water can be supplied directly from shore hydrants via hoses or delivered by road tankers (trucks). Additionally, a dedicated Kenya Ports Authority (KPA) fresh water barge is available to service vessels at any berth and at the designated port anchorages. All water supplies must be arranged through your local port agent. To ensure accurate billing, it is highly recommended that a vessel representative witnesses the meter reading at the start and completion of the supply. Given that water quality can vary, testing may be advisable for critical uses.

Ship Chandlery Services

A full range of ship chandlery services, including provisions, bonded stores, spare parts, and deck/engine stores, is available in Mombasa. For ship/vessel operators, it is standard practice to coordinate all such supplies through your appointed local shipping agent. The agent will connect you with reputable, licensed ship chandlers and manage the logistics of delivering supplies to your vessel, whether at berth or anchorage.

Scope of Attendance

• Pre-bunker conference with Master/CE & supplier.
• ROB measurement and receiving tank capacity verification.
• Witnessing of meter/tank calibration evidence and seals.
• Sampling per MARPOL & ISO standards; chain-of-custody.
• Hose, manifold, and seal integrity checks.
• Quantity dispute handling, protest letters, and evidence capture.
• Final reconciliation: BDN cross-check and variance analysis.
• ISO-Compliant Reporting: All reports are structured to meet international standards, providing clear, actionable data for your records.

Common Risks

• Entrained air (“cappuccino” effect) inflating volume.
• Incorrect temperature or density data application.
• Meter or truck calibration gaps (lapsed certs, wrong K‑factors).
• Unverified tank soundings or inaccurate tables.
• High flow rates at start/stop introducing air.
• Poor sampling practices and broken chain-of-custody.
• Documentation errors on the Bunker Delivery Note (BDN).

Controls We Enforce

• Independent ROBs with calibrated thermometers/hydrometers.
• Disciplined flow rates and observation for aeration.
• Witnessed calibration evidence; seal numbers recorded on BDN.
• Representative continuous drip sampling and MARPOL sealing.
• Line displacement and manifold drain verification.
• Immediate variance analysis and written protests if required.
• Clear Communication Protocols: Ensuring instructions are understood between multinational crews to prevent operational errors.
• Thorough photographic evidence dossier for all key stages.
