Supply of HVO fuel to RRS Discovery and RRS James Cook September 2026

Supply of Hydrotreated Vegetable Oil (HVO) fuel to two National Oceanography Centre research vessels by way of two bunker deliveries at two ports on consecutive days. The contract is to be awarded to Standard Fuel Oils Limited as a single contract covering both deliveries, each performed against its own delivery reference.

Delivery D-01: RRS Discovery (IMO No. 9588029). Estimated quantity 252 m³ (252,000 litres).

Required delivery date 15 September 2026. Delivery D-02: RRS James Cook (IMO No. 9338242).

Estimated quantity 430 metric tonnes, approximately 551,000 litres. Required delivery date 16 September 2026.

Aggregate estimated quantity approximately 803,000 litres. All quantities are estimates.

Payment will be made solely on the actual quantity delivered against each delivery reference, as evidenced by the Bunker Delivery Note for that delivery and by the actual density recorded on the Certificate of Analysis at 15 degrees Celsius. No minimum or maximum quantity is guaranteed and the contract value stated is therefore indicative.

Delivery is by road tank wagon (RTW) to each vessel at its stated berth. The exact delivery window and operational hours for each delivery will be confirmed to the supplier in writing no later than five days before delivery.

Fuel must comply with EN 15940 and must be derived from used cooking oil (UCO) feedstock only, with no palm oil, palm oil sludge, POME, or animal fats. Sulphur content must comply with MARPOL Annex VI and the applicable MCA requirements, at less than 5 mg/kg (5 ppm).

Flash point must be not less than 60 degrees Celsius, in line with SOLAS. CFPP must be minus 15 degrees Celsius or lower.

Greenhouse gas emissions intensity of 15.86 gCO2e/MJ with a minimum 83 per cent saving against fossil diesel, and biogenic carbon (C14) testing on all imports. Fuel is to be supplied on a non-obligated basis in line with the requirements for marine research use.

The supplier is registered on the Maritime and Coastguard Agency Local Fuel Oil Suppliers Register as compliant with MARPOL Annex VI, and is registered on the Central Digital Platform with a current Public Procurement Organisation Number. A Bunker Delivery Note must be provided in the MARPOL Annex VI Appendix V format, stating quantity in metric tonnes, carrying the supplier's signed declaration that the fuel meets the fuel quality requirements of MARPOL Annex VI Regulation 18, together with the sulphur content statement and the flash point statement.

A representative MARPOL fuel sample must be drawn, labelled and sealed in accordance with MARPOL Annex VI. The following sustainability documentation is required for each delivery: proof of sustainability of the biofuel component, certified under either ISCC or RFAS 2 Heat-Power-Marine (RSB is not required), a biofuel delivery statement, and the greenhouse gas emissions data for the fuel supplied.

The requirement was competed through a competitive quotation exercise on a best and final basis. Suppliers were invited to price each delivery on the basis that it might be awarded alone, and separately to price both deliveries taken together, and were permitted to bid for one delivery only without disadvantage.

Award is made on the basis of the Most Advantageous Tender, tested by comparing the aggregate of the individual delivery prices against the price offered for both deliveries together. Award of both deliveries to a single supplier is the most advantageous outcome available. A transparency notice was published in advance of this notice under reference 2026PRNOC-1244.
