瓦锡兰开发兼容型BOG再液化系统

据离岸工程网站7月7日消息 芬兰技术集团瓦锡兰公布了其再液化系统，旨在重新液化天然气船和液化天然气船上的蒸发气体（BOG）。

该解决方案名为兼容型再液化装置也被设计来保持货物在所有操作条件下的冷却。瓦锡兰在声明中表示，它可以安装在现有船只上，而无需进行大量的改装工作。

瓦锡兰海洋系统天然气解决方案销售和市场总监Kjell Ove Ulstein表示：“随着全球液化天然气应用市场的不断扩大，满足这些日益增长的需求需要更大的灵活性。”

与之前交付的瓦锡兰再液化系统一样，Compact Reliq基于布莱顿技术，这使得一部分BOG可以用作船只的燃料，而多余的可以液化并与液化天然气货物一起出售。

瓦锡兰表示，液化BOG而不是在气体燃烧装置中燃烧也有积极的环境影响，因为没有气体被释放到大气中。

该系统易于进行远程监控和在线操作支持，并且在5年间隔对接期间需要最少的维护。

该系统与瓦锡兰的操作性能改进和监测（OPERIM）兼容，并可与船舶计划维修系统（PMS）完全集成。

W?rtsil? develops compact BOG reliquefaction system

The Finnish technology group W?rtsil? has unveiled its reliquefaction system designed to reliquefy boil-off gas (BOG) onboard gas carriers and LNG bunker vessels.

The solution named Compact Reliq reliquefaction plant is also designed to keep the cargo cool under all operational conditions. It can be installed on existing vessels without extensive modification work, W?rtsil? said in its statement.

“As the global market for LNG applications expands in response to increasing environmental regulations, greater flexibility in meeting these growing needs is required,” says Kjell Ove Ulstein, director sales & marketing, gas solutions, W?rtsil? Marine Systems.

As with previously delivered W?rtsil? reliquefaction systems, the Compact Reliq is based on Brayton technology. This allows a portion of the BOG to be utilised as fuel for the vessel, while the excess can be liquefied and sold with the LNG cargo.

Liquefying the BOG instead of burning it in a Gas Combustion Unit also has a positive environmental effect, as no gases are released into the atmosphere, W?rtsil? said.

The system is readily instrumented for remote monitoring and online operational support and requires minimal maintenance between 5-year interval docking.

The system is compatible with W?rtsil?’s Operational Performance Improvement and Monitoring (OPERIM) protocol, and can be fully integrated with the ship’s Planned Maintenance System (PMS).
