Bunker One USA has detailed a series of operational measures introduced to manage prolonged pressure on margins and volumes in the US marine fuels market, according to a company update issued on 9 December. The firm said it is combining tighter data oversight with operational flexibility to remain competitive amid challenging conditions.

The company noted that it tracks volume and margin developments through structured record-keeping and performance analysis, which it said helps identify market shifts early. It added that planning is shaped by anticipating potential downturns, allowing operational adjustments before pressure intensifies.

In its in-port physical operations, Bunker One USA said it has reduced tug-and-barge costs by releasing long-term charters and relying more on spot tugs where appropriate. The supplier has also consolidated elements of its fleet operations through cooperation with Kirby, thereby improving scheduling efficiency and barge utilisation.

In New Orleans and Mobile, the company has stepped back from chartered tug-and-barge activity while retaining storage tank capacity to maintain flexibility and lower fixed costs.

For offshore supply operations, Bunker One USA highlighted the deployment of a new tanker designed to shorten connection times, streamline documentation processes and improve pumping rates. The company said a revised commercial management structure has supported tighter scheduling control and enhanced reliability, even in more demanding conditions.

Bunker One USA added that total offshore volumes have increased, helping balance the effect of declining premiums. At the same time, a shift toward higher intake of high-sulphur fuel oil reflects recent demand patterns.

The supplier said its commercial strategy focuses on long-term customer relationships and on accelerating the pursuit of new business opportunities. According to Bunker One USA, these combined measures reinforce its resilience and will support growth when market conditions improve.

The US bunker market has faced sustained pressure from compressed margins and volume constraints in recent years, prompting suppliers to adjust their operational models to maintain viability in a competitive environment.
