BW Lesmes has completed its first gassing-up and cool-down (GUCD) operation using an LNG bunker barge, according to BW LNG.

The procedure brings the vessel from inert gas conditions to cargo readiness following drydock and requires tightly controlled execution.

The operation was a first for the company, introducing challenges across planning and onboard delivery.

Master Capt. AdityA Sharma, the crew of BW Lesmes and shore-based operator Zekai Çolakoğlu executed the process with a focus on safety and coordination.

The milestone adds operational capability in handling GUCD procedures involving bunker barges and supports deployment in similar conditions.

BW LNG is a company engaged in the ownership and operation of LNG carriers and floating gas infrastructure, including floating storage and regasification units, supporting the global gas supply chain.
