The ethane gas carrier segment has grown both in number of vessels and vessel sizes. The vessel sizes are in the range from 90k m³ to 100k m³.
The rationale behind the fleet growth is large amount of new ethane to the market and long sailing distances.
Gas Solutions has become the leading supplier of cargo handling systems for Very Large Ethane Carriers (VLEC`s). The cargo systems are designed with integrated ethane fuel supply system (LEG FGSS) for the dual fuel main engine. The system design enables the vessels to trade ethylene as a second cargo.
The system supply comprises cargo system engineering, material supply and hand-over to owner with crew training services included.
Technical data
Gas Solutions has been developing the LEG cargo handling systems since the early days of the industry. Primary cargo is Ethane, but in addition the vessels have capability to carry ethylene and LPG gases.
The system design is to ensure safe, efficient, operator and Eco-friendly cargo handling operations. The gas carrier will smoothly load and keep the cargo refrigerated during laden voyage ahead of discharging.
The system is designed with aim to reduce operating costs, contribute to an improved vessel EEDI and reduce overall emitted GHG to the atmosphere.
The heart of the system is the BOG handling plant which is of cascade type; one primary stage and one secondary stage. The system is proven and shown reliable via many sailing reference vessels.
The system supply includes the cargo control system which enables remote monitoring and control of the system including various subsystems as Inert Gas System and interface to the Load Computer.
Applications
Typical trade patterns are from US East coast to China or India. The ethane is feedstock for chemical industry and the final products are diversified.
The vessels have grown large and utilizes tanks of membrane type, allowing carriage of cargoes at temperatures down to -92°C.
Most of the new vessels are designed with LEG fuel supply system (LEG FGSS) for the main engine. Gas Solutions has developed a state-of-the-art fuel system that is designed to be integrated with the cargo handling system.
Gas carriers must comply with the standards set by the Gas Code (IGC) and national rules, and the cargo handling system is designed in accordance with those rules.
Key benefits
