ClassNK grants AIP on LPG Reformer for marine engines

Japanese technology firms Osaka Gas and Daihatsu Diesel received an Approval in Principle (AIP) from ClassNK for their joint project on an LPG Reformer for marine engines. This was the first AIP granted in Japan for such equipment.

The LPG Reformer is designed to convert LPG into synthetic methane gas equivalent to the kind found in LNG, ClassNK explained.

Due to being mainly composed of propane and butane, LPG is susceptible to knocking (abnormal combustion), making it difficult to use as a fuel...

Main Engine Damage due to bunkered fuel quality

A General cargo ship “M” was involved in cargo operations in an Indonesian port. Charterers had arranged the vessel to receive bunkers by a local bunker barge. The barge moored alongside of the vessel for supplying the agreed amount of 155M/T of fuel oil (180cst) into No.1 & 2 F.O. tanks respectively. Both tanks had been cleaned from previous stored fuel prior bunkering. Bunkering operation was completed and the bunker supplier provided the cargo vessel with the required fuel oil sample...

Digital Twin in action: Advanced real time diagnostics for ship engines

During the 2019 SMART4SEA Conference, Dr. Panos Theodossopoulos, CEO, Propulsion Analytics, presented, together with WinGD, a real time Engine Diagnostic System (EDS) available in all WinGD 2-stroke, diesel and dual fuel engines.

The core principle of the technology employed in EDS is the concept of the digital copy of the physical engine. That’s what we call the ‘digital twin’, a term that is also becoming quite trendy in the maritime industry. The digital twin onboard helps us assess the...

Operation on high thermal load damages engine

The Swedish Club provides lessons learned from a machinery failure. Namely, the main engine, a six cylinder medium speed type, had serious damage and had to be renewed. Moreover, the turbo charger had to be overhauled.

The incident

A vessel was in ballast and at anchor, waiting for further instructions. After seven days the weather got worse and the ship’s anchor dragged. The anchor was heaved up and the vessel started to slow steam in the area.

“K” Line trials binary cycle power generation system on new ship

Japanese shipping company “K” Line announced that one of its new 91,000-DWT-type coal carriers, ‘Corona Youthful’, was delivered with a binary cycle power generation system developed by Kobe Steel, Ltd. at Oshima Shipbuilding, on 1 February 2019.

Binary cycle power generation system is a waste heat recovery electric power generation system utilizing compression heat by scavenging air from the main engine, which, in turn, contributes to reduction in fuel oil consumption of diesel generator engine.
