AiP Granted for Ammonia Release Mitigation System

Azane Fuel Solutions has received Approval in Principle (AiP) from DNV for its Ammonia Release Mitigation System (ARMS).

The approval comes as Azane Fuel Solutions continue to develop technologies to safely handle ammonia as a fuel on board ships and builds on the company’s expertise within ammonia bunkering solutions.

The Azane ARMS is connected to the vessel’s fuel and engine systems. It gathers the ammonia releases from these systems and ensures that any ammonia emissions from the ARMS to the surroundings stay below the required thresholds.

The aim is to protect the vessel’s crew and the environment from harmful concentrations of ammonia.

DNV’s approval adds to its prior approval in principle for the company’s floating bunkering terminal in 2022, and the world’s first safety permit for an ammonia bunkering granted earlier this spring. The planned terminal consists of a floating stationary barge with a capacity of 1000 cubic meters, or 650 tons, of low-emission ammonia. The permit allows for up to 416 operations annually, many of these expected to be bunkering operations for offshore supply vessels that regularly call at Fjord Base in Florø.

The planned terminal is part of Yara Clean Ammonia and Azane’s efforts to make low-emission ammonia a common fuel for shipping.

Steinar Kostøl, VP Projects & Products, said: “Efficient ARMS technology is a critical enabler for the wider adoption of ammonia as a marine fuel, as we expect this to become mandatory equipment for all ammonia powered vessel. When developing our bunkering solutions, we looked for a way to minimize the maintenance required for the ARMS. We wanted a more dependable solution for such a critical component. The result is a technology that neither requires a liquid or the burning of residuals, making our solution more robust, more reliable and easier to integrate with different vessel designs.”
