Classification society Bureau Veritas (BV) granted approval in principle (AiP) to Marine Service and Newport Shipping. They have jointly developed a containerized LNG solution.
The 40′ ISO LNG fuel tank container system is suitable for LNG-fueled newbuilds and retrofits of container vessels.
Specifically, it is a class-approved Type C LNG fuel tank; in accordance with the IGF code and is based on the German TÜV certified IMDG Container. The capacity of the tank is 31 gross tonnes and about 33m3 of LNG.
Note that, he containers have a fail-safe dry quick coupling connection. Moreover, they carry approval for loading in up to seven layers of high stacks. The stainless-steel double-walled tank has also vacuum insulation with 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. Furthermore, the gas handling room arrangement is 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. Nonetheless, it has full redundant control, alarm, and monitoring system for remote system operation, gas, and fire alarm with an interface to ships’ automation is part of the system.
Due to the portability of the LNG containers, the total number of containers has easy optimization 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 newly filled ones.
“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.”Ingmar Loges, managing director of Newport Shipping
“We are glad to have reached an Approval in Principle from BV for our containerized LNG as fuel solution. LNG is one of the most promising alternative fuels by now,”Christian Krämer, chairman of Marine Service.
Marine Service develops several LNG fuel solutions including tank containers. The containers are an alternative solution to traditional LNG bunkering.
Newport Shipping offers its customers full retrofit services for Marine Service GmbH’s LNG fuel tank container solutions at its 15 yards that it works in cooperation with.
