UK2 - Preliminary Market Engagement Notice
Summary of the contracting process

International Nuclear Services Limited, part of Nuclear Transport Solutions, is procuring a global bunker procurement service and associated supply-chain management for the PNTL fleet of vessels. The service will support the buyer’s nuclear shipping operations by sourcing and managing bunker fuel, enabling flexible and resilient vessel operations worldwide. The requirement covers commodity brokerage, ship refuelling and fuel-related supply-chain services, rather than the purchase of bunker fuel itself. Delivery is required globally, with the stated delivery locations including the United Kingdom and Japan. The buyer is seeking one suitably qualified and experienced supplier to provide consistent oversight and operational coordination under a unified arrangement. This is a services opportunity relevant to bunker brokers, bunker suppliers, bunker traders and firms managing marine-fuel procurement for international shipping operations.

The procurement has reached tender: the buyer invited offers through an open competitive flexible procedure with multiple stages. Suppliers first complete supplier information and procurement-specific questionnaires alongside an invitation to tender; the highest three scoring tenderers proceed to later presentation and evaluation stages. Enquiries close at 12 noon on 21 August 2026, and tenders must be submitted by 12 noon on 4 September 2026. The award decision is due by 16 November 2026. The contract is scheduled to run from 25 January 2027 to 24 January 2029, with an optional 24-month extension to 24 January 2031. The service value excluding bunker supply is estimated at £21,500–£107,600 for three years and £35,700–£179,000 for five years, excluding credit costs. There is one lot. Evaluation is 55% technical quality and 45% price.

This opportunity suits SMEs as well as larger suppliers with established international marine-fuel networks and the capacity to support vessels across multiple jurisdictions. Strong candidates are likely to have practical experience in bunker procurement, commodity brokerage, ship refuelling, supplier management, logistics coordination and fuel-market trading. The requirement favours organisations able to provide resilient global coverage, compare and manage supply options, coordinate deliveries and maintain consistent service quality for an operational shipping fleet. Experience supporting complex, safety-critical or regulated shipping operations would be relevant to the buyer’s nuclear transport environment. Suppliers must meet the economic selection requirement of a maximum Dun & Bradstreet risk rating of 2, or an equivalent rating. Responses are to be submitted electronically in English, and the staged process requires both technical and commercial capability followed by a presentation for shortlisted tenderers.
