Classification society Bureau Veritas (BV) granted approval in principle (AiP) to Marine Service and Newport Shipping for a jointly developed containerized LNG solution.
The 40′ ISO LNG fuel tank container system is suitable for LNG-fueled newbuilds and retrofits of container vessels.
It is a class-approved Type C LNG fuel tank in accordance with the IGF code and is based on German TÜV certified IMDG Container.
The capacity of the tank is 31 gross tonnes and about 33 cubic metres of LNG.
The containers have a fail-safe dry quick coupling connection and are approved for loading in up to seven layers of high stacks.
The stainless-steel double-walled tank is also vacuum insulated and has up to 80 days of holding time.
The concept consists of container stowage on a free deck in a safe area. LNG piping and venting system, as well as firefighting systems, are integrated into the container cell guides structure.
The gas handling room is arranged adjacent to the container storage and separated from the containers by a cofferdam and fire protection means, allowing to feed low pressure and high-pressure fuel gas systems for all known 4-stroke and 2-stroke dual-fuel engines.
A full redundant control, alarm and monitoring system for remote system operation, gas and fire alarm with interface to ships’ automation is part of the system.
Since LNG containers are portable, the total number of containers can be easily optimised according to the owners’ requirements.
Simple and easy to install on board, when a ship is in port, the empty containers can be taken out and replaced by new filled ones.
Ingmar Loges, managing director of Newport Shipping, said:
“The global shipping industry faces unprecedented challenges as environmental regulations tighten. The shipping industry needs alternatives. The containerized LNG concept provides an answer to these challenges.”
