The initially in a collection of 6 LNG-fueled neo-Panamax containerships has actually efficiently finished sea and also LNG gas tests inKorea The ships are being developed for Singapore- based Eastern Pacific Shipping at the HSHI (Hyundai Samho Heavy Industries) shipyard and also are each powered by a MALE B&W 11G90ME-GI primary engine. The engines are the very first to include MALE Energy Solutions’s Pump Vaporizer Unit (PVU).
CMA CGM has actually currently hired the very first vessel, called Tenere, from Eastern Pacific.
“The successful gas and sea trials and the on schedule delivery of CMA CGM Tenere make for an important MAN and EPS milestone,” claimed Eastern Pacific Chief Executive OfficerCyril Ducau “Three years ago, we committed to investing in alternative marine fuels, like LNG, to lead the industry towards decarbonization and environmental preservation. This commitment included selecting MAN’s high-pressure ME-GI engines, which are highly efficient and, importantly, reduce methane slippage to negligible levels. These vessels will be IMO 2030 compliant years ahead of schedule and will be the cleanest vessels of their category on-the-water today. My sincerest thanks and congratulations to everyone involved in this exciting project.”
MALE Energy Solutions states that the engine is the biggest and also most effective (MCR 68,640 kW) gas-engine it has actually created to day, with solution experience from ME-GI drivers taping a gas-availability price of higher than 98%, a testimony to its security and also integrity.
The brand-new engine includes a variety of current, technological growths, consisting of the PVU and also Pilot Booster Injection Valve (PBIV).
Bjarne Foldager, Senior Vice President and also Head of Two-Stroke Business at MALE Energy Solutions, claimed: “I am delighted to receive the positive reports from these successful gas-trials where testing has proceeded smoothly according to the plan laid for the engine’s entry into service. I am also very encouraged by the reports of good cylinder conditions. The ME-GI engine is mature technology that has accumulated multiple references in multiple segments and is further improved by the introduction of the PVU, which ensures an optimal integration between the engine and supply system.”
HHI-EMD revealed the conclusion of the store examination for the very first of the 6 ME-GI engines at the end of January 2020. MALE Energy Solutions reported back then that the engine had actually efficiently gone for 100% tons in gas setting throughout screening, capably managing load-changes and also preserving a remarkable cyndrical tube problem. MALE Energy Solutions additionally reportedthat time that the engine– with no demand for extra screening– had actually efficiently passed its FAT (Factory Acceptance Test) and also done entirely according to assumptions, perfectly managing loadchanges and also gas change-overs while preserving flawless cyndrical tube problems.
TECHNICAL DEVELOPMENTS
The effective Eastern Pacific gas-trial marks the business launching of the PVU8000, the biggest PVU ever before created by MALE Energy Solutions and also the biggest offered on the aquatic market. The system guarantees the trustworthy circulation of LNG via a portable style that– via specific control of the cryogenic pumps (cold-ends)– supplies the redundancy called for to guarantee high integrity whatsoever times.
The engine additionally includes MALE Energy Solutions’ brand-new Pilot Booster Injection Valve (PBIV), which utilizes smaller sized or bigger atomizing openings– relying on gas setting– to infuse gas right into engines. As such, in gas setting, making use of smaller sized openings dramatically lowers pilot-oil intake to simply 1.5%, around fifty percent of what was formerly called for; diesel setting utilizes the larger-sized openings. The PBIV shutoffs stand for MALE Energy Solutions’ most current pilot-injection modern technology, which provides for dual-fuel operating by optimizing SPOC (Specific Pilot Oil Consumption).
