On this yr’s largest methanol order up to now, the Alfa Laval FCM (Gasoline Conditioning Module) Methanol would be the low-flashpoint gasoline provide system (LFSS) on six dual-fuel container vessels. The system was chosen for each its real-life efficiency and its excessive design flexibility.
Alfa Laval will present the methanol LFSS for six 1170 TEU container vessels ordered by Eastaway, a member of the X-Press Feeders Group. The brand new vessel collection, to be constructed at Chinese language shipyards Ningbo Xinle Shipbuilding Group Co., Ltd and New Dayang Shipbuilding Co., Ltd, can have two-stroke MAN B&W ME-LGIM engines that may run on methanol in addition to typical fuels. The FCM Methanol deliveries will start in June 2023.
The FCM Methanol is a dual-stage, pressurized system that provides methanol safely and mechanically. It may be organized to feed a number of gasoline traces concurrently with totally different course of parameters, thereby assembly the wants of a number of engines and boilers.
Every stage is protected by a strain reduction valve and is provided with transmitters and indicators for strain and temperature. The low-pressure stage prevents the cavitation of the high-pressure pump. The high-pressure stage maintains the required gasoline parameters.
The system’s automation handles all mandatory gasoline routines, guaranteeing that the methanol is conditioned and prepared for a begin sign from the engine management system (EGC). Upon a cease sign from the EGC, the system safely returns to standby.
Management and monitoring are dealt with from a management cupboard situated inside a secure zone, or from the vessel’s automation system by way of Modbus serial hyperlink. Superior troubleshooting will be carried out from any management level, with out getting into the hazardous zone.
To forestall leakage, the methanol pumps are geared up with magnetic couplings as commonplace. The warmth exchangers that management the gasoline’s temperature are fed by a built-in glycol water circuit, which safely segregates the methanol from the vessel’s heating and cooling media. The ten-micron, double block-and-bleed duplex filter permits upkeep to be per- fashioned safely on one filter chamber whereas the opposite stays in operation.
The FCM Methanol is ATEX-certified and complies with IGC Code, IGF Code and DNV Pt.6, Ch.2, Sec.6.
As a result of methanol expertise is a brand new ingredient in shipbuilding, yards undertake totally different setups to go well with their studying curve. Given the complexity and scope on this mission, the yards have employed engineering firms to acquire and combine the methanol-related parts. The FCM Methanol was chosen as a consequence of its distinctive flexibility and Alfa Laval’s in depth methanol expertise.
With mature applied sciences and dependable automation, the FCM Methanol safely provides methanol inside the circulation fee, strain, temperature, and filtration parameters specified by the engine maker. As a result of it may be tailored to any engine and vessel design, it allows turnkey LFSS deliveries for straightforward set up. Since 2015, the system has been chosen in practically 20 methanol initiatives for greater than 10 giant transport firms.
