The issue, according to HFW, often stems from conventional fuels—particularly Very Low Sulphur Fuel Oil (VLSFO)—that are not consumed within their prescribed shelf life, rendering them unsuitable for use and requiring costly disposal.   When LNG prices fall below those of conventional fuels, charterers tend to maximize LNG consumption to save costs. However, this strategy may expose them to serious financial risks, as the loss in value of offloaded or expired fuel is generally not insurable.   The CIMAC association has noted that while High Sulphur Fuel Oil (HSFO) can remain stable for up to two years, VLSFO typically has a shelf life of only three to six months. This means that when LNG is used as the primary energy source, VLSFO may remain onboard for long periods and exceed its usable lifespan—posing operational and financial risks for both owners and charterers.   It might seem straightforward to assume that fuel-use decisions fall solely under the charterer’s responsibility, but in practice, the situation is more complex.   While time charter parties typically specify the minimum quality of fuel to be supplied by the charterer, they seldom define who is responsible for ongoing monitoring of fuel condition.   However, under the ISM Code, shipowners are required to include within their Safety Management System (SMS) appropriate risk assessments, operational procedures, and fuel quality testing before any bunkering operation. For LNG dual-fuel ships, owners should conduct regular monitoring and sampling of both fuels to ensure they are co
