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
Bunkering area to be
approved for LNG
• Authorities
• Port
Bunkering procedure (including
HAZID and Risk Assessment)
to be approved from
• Authorities & Port
• Class society

The Project - LNG bunkering ship to ship
• HAZID – Hazard identification for bunkering operation
• Risk assessment for identified hazards
• Bunkering procedure including technical solutions
Approved in principle by the class society DNV

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

• How to communicate – language, methods
2010-06-16
19
• Preparations
• Checks (Tank system, hoses, equipment)

5.1.1 LNG Tank System Check
• Tank pressure and temperature for both
ships within acceptable levels
2010-06-16
31
5.6 Communication Link (optional)
• Overview level in receiving tank
• Tank Pressure
• Valves
• Digital checklists• Digital checklists
• Receipt
2010-06-16
32
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

and safe LNG Ship to Ship bunkering
• Operational procedure for Ship to Ship LNG

- We have the answer of how to bunker LNG fuelled ships
• Operational procedure for Ship to Ship LNG bunkering, including checklists
