Heliad III

A study in purposeful engineering and blue‑water poise, Heliad III is driven by twin 493 hp Cummins QSC8.3 diesels delivering a combined 736 kW at 2,600 rpm, with a stated total power of 500 hp per side. Hours as of February 2026 stand at 2,015 on the port engine and 2,021 on the starboard. The 8.3 ltr displacement blocks are coupled to ZF360 gearboxes, and the main engines have been professionally maintained by Cummins France from launch in 2020. A diligent annual servicing regime culminated in November 2025 and encompassed oil and oil‑filter changes, fuel‑filter replacement, a full body service of the raw sea‑water pumps, intercooler oil and fuel cleaning, and inverter services for both sides. The comprehensive cooling‑system programme included removal and full chemical cleaning of the heat exchangers, aftercooler core removal with cleaning and pressure testing, transmission‑oil cooler cleaning, and a coolant flush and refill with Cummins Coolant ES Compleat. The fuel system benefitted from injector balance checks with replacement where spray patterns were out of spec, and inspection of the high‑pressure fuel pump. Turbocharger care included inspection for shaft play, VGT mechanism cleaning if fitted, and replacement of any corroded V‑band clamps. Air‑intake service comprised air‑filter replacement or upgrade to a high‑flow element, while the exhaust system was checked to eliminate riser leaks and to verify elbow condition, especially where mixing elbows are stainless or bronze. Electrical checks ran to alternator load and charge testing and a starter‑motor inspection, which is typically due for replacement around two to three thousand hours. Mounts and alignment were verified with engine‑mount torque and condition checks and laser shaft‑alignment confirmation. Downstream, propulsion hardware is equally robust, with 2 x Poseidon Propulsion BV propulsion shafts, 2 x Poseidon Propulsion BV stern tubes with bearings and seals, 2 x Poseidon Propulsion BV shaft brackets with bearings, 2 x Poseidon Propulsion main propellors, and 2 x Poseidon Propulsion rudders with stock and bearings, the latter replaced in December 2025.
