GTT Inside #27 - January, 2023

Message from Anouar Kiassi, Digital & Information VP of GTT

Anouar Kiassi

Over the last years and months, we have witnessed an unprecedented pressure on the maritime industry to adopt environmentally friendly measures. In this respect, 2023 is a turning point with entering into force of the CII regulations. Yet, this year is just one among many others still to come with all the new regulations already adopted or being adopted (EU ETS, Fuel EU Maritime…).

Judging by the conclusions of the latest Intersessional Working Group on Greenhouse Gases (ISWG) and Marine Environment Protection Committee (MEPC), the industry is expected to adopt an even more ambitious GHG reduction strategy in the coming years.

These are exciting but challenging changes. However, experience has shown us that the most efficient way to drive the change, is to align environmental and economic considerations. In this issue, dedicated to our latest digital innovations, we showcase three software solutions that answer these two concerns with clear benefits.

I hope you will enjoy the articles. I also take this opportunity to wish you, on behalf of the GTT Group a wonderful new year for 2023!


Route Optimisation

Route-planning and optimisation involves juggling many constraints related to safety, operations and compliance. For ship captains, this is an essential and complex task that requires the aid of a decision-supporting tool to give them confidence in their decisions and support execution.

GTT has developed an advanced route optimisation solution that is capable of advising the best route by optimising numerous parameters and respecting a large number of operational constraints...

Cargo Tank Entry extended periodicity of LNG carrier

The regulations require the LNG carriers owners to inspect all the tanks every 5 years regardless of their operational profile:

  • IACS UR Z16 §2.2.1: All cargo tanks are to be examined internally.
  • 2016 IGC Codes §  A renewal survey at intervals specified by the Administration, but not exceeding five years.

The objective of the survey is to identify and eventually repair potential defects or damage on the Cargo Containment System (CCS), and the Pump Tower (PT). Such defects are generally associated with the liquid motion in the tanks...

Cargo conditioning

LNG carriers have to meet the terminal requirements in order to be allowed to unload the cargo. The requirements define acceptable ranges for different parameters like LNG composition, Gross Heating Value, Wobbe Number, LNG density, Saturated Vapour Pressure, Temperature…

During the laden journey, new commercial instructions might be received leading to a change in the time of arrival and/or the discharge port. When this happens, the LNG cargo may be in unacceptable condition for the new discharge terminal...
