GTT monitoring of liquid motion to improve carrier efficiency

LNG Industry,


GTT and its partner Cryovision have launched an innovative monitoring system to help reduce the effects of liquid motion in LNGCs (liquefied natural gas carriers), including extra boil-off of LNG cargo, due to ‘sloshing’ inside the vessel’s tanks.

SloShield tool

The new tool, SloShield™, uses an advanced algorithm that allows LNG carrier crews to constantly monitor the vibrations in each tank’s structure due to specific sloshing activity by consulting easy-to-read screens in real-time. This allows crews to make critical decisions based objective indicators to optimise the ship’s operation.

This first generation SloShield™ is the result of more than three years of prototyping onboard an LNGC in real operational conditions, which qualifies it as a sea-proven, safe and reliable system. It was developed from a joint effort between GTT engineers, using actual historical data on liquid motion in navigational situations, and the Cryovision team, which has packaged the offer and will install the tool.

SloShield™ will be distributed by Cryovision on a turn-key basis that includes: studies, class validation, procurement, erection and commissioning. In addition, GTT experts are available to review the sloshing data, together with the operational environmental parameters to capitalize on each vessel’s specific experience.

Comments

Cryovision COO, Julien Glory, commented: “Flexibility and reliability are key words for us. A SloShield™ installation can even be done while LNGCs are at sea to accommodate customer constraints and schedules.”

GTT CEO, Philippe Berterottière added: “We are excited to add this new offer to our expanding services portfolio. At GTT, we constantly seek new ways to provide value-added innovations that increase LNG carrier efficiency to ensure they stay at top performance levels.”
