Standards and Requirements to be Followed:

• 1970’s : Gas Tank & Code Development Era• IGC - ”International Code for the Construction and Equipment of Ships

Carrying Liquefied Gases in Bulk”:

• “IMO Interim Guidelines on Safety for Natural Gas Fuelled EngineInstallations in Ships”

• Local requirement/Flag state requirement

• Class requirement/class guidelines• DNV Rules Part 6 Chapter 13 Gas Fuelled Engine Installations




Challenges

Main challange is to optimise and reduce the energy consumption on

vessels:

• Utilise Boil-off gas (energy in the gas and cold duty)

• Utilise the available cold duty in the LNG as fuel:

• Air-condition

• Refrigeration

• Cooling inlet air to engine

• Cooling jacket water (normally done with sea water)

• Cool or liquefy cargo with LNG (VOC, gas etc)

Important to look at the complete energy

balance of the vessel!

Utilizing available energy – Optimize the energy consumption




Challenges System

• Vent – Not an alternative!

• Pressure build up in tank (C-tank)

• Fuel gas for engine (LP/HP/BOG-compressor)

• Boil-off gas reliquefaction system (full/partial)

• Boil-off gas recondenser – vessel in operation

• Gas-combustion unit (GCU)/flare/dump condenser

• Utilise the boil-off gas for heating purpose (e.g. boiler)

• Production of electricity in an auxillary engine/gas engine

Handling of Boil-off gas (BOG) from fuel tanks/Boil-off gas control
