LNG, the future fuel for

Short Sea Shipping?

- Increase of oil price!

- Stricter environmental

legislations legislations

- Environmental concern of the

transport buyer

- LNG, the bridge over to LBG

(renewable gas fuel)Complies with

emission regulations

within SECA after

What needs to be cleared before LNG bunkering ship to

ship can be performed?

Port to be approved for

LNG activities

• Authorities

• Port

Important parameters for the project

• Fast and Safe bunker procedure

• Bunker operation should not prolong stay in port

(The bunker scenario: maximum bunker time 50 minutes,

bunker quantity LNG: 130m3 = 65 ton)

• Bunkering of LNG and MGO / MDO at the same time

• Environmental concern, minimal environmental impact from

bunkering procedure

• Proven technology

2010-06-16

• Based on known and accepted guidelines from

OCIMF and SIGTTO

5.1.1 LNG Tank System Check

• Tank pressure and temperature for both

ships within acceptable levels

5.6 Communication Link (optional)

• Overview level in receiving tank

• Tank Pressure

• Valves

• Digital checklists• Digital checklists

• Receipt

6.4 Pump Start Sequence

• Check for leaks

• If not right pressure in hose, process

will be stopped automatically

• Bunkering starts in 6.5

2010-06-16

33

7.1 Purge Hoses

• Purging with heated LNG, natural gas, to

empty hose from liquid

• Liquid is pushed to the receiving ship

2010-06-16

34

7.3 Disconnection of hoses

• Drip free quick connect

• Hose parking on bunker ship in order to

control gas emissions

2010-06-16

35

7.8 Inerting of Cargo Hoses

• Inerting must be done before

departure for the receiving ship

• If there is short time to next

bunkering for the bunker ship, hoses

does not need inerting

• If no bunkering is awaiting, inerting

of cargo lines should be done after

the bunker ship has left the bunker

area

36

• CRYO has discovered a

way to pump LNG without

using a pump

Alternative technologies

• Fast and secure hose

handling with TTS Hose
