Project duration 01/01/2012 - 31/12/2015

Executed by 6 different Joint Industry Projects:

A crucial part of establishingLNG infrastructure for marine application

Ander Bejre, Project Manager Sirius Shipping AB

A bunker/ feeder vessel is an essential part of the infrastructure chain necessary in order to provide LNG to vessels operating to and from the Baltic Sea.

The objective of the activity:

“To develop the LNG bunkering infrastructure by offering a LNG bunkering possibility in the Skagerrak/Kattegat area in cooperation with the Skangas Terminal in Brofjorden. The development of a fast, efficient and safe bunkering system and procedures for LNG bunkering inshore and offshore is also part of the activity.”

PILOT LNG – Activity 2: Building of Flexi LNG bunker tanker

• Founded in 1994 by the Backman family, a family with old seaman’s traditions, on the island of Donsö in the south archipelago of Gothenburg.

• Today Sirius operate 10 tankers that together make more than 1000 voyages a year and 1 LNG Supply vessel, that as of today has completed more than 800 successful STS LNG bunker operations.

• The company has commercial management for 23 tankers and a sister company that offers port agency services along the entire Swedish coast.

General Manifold Requirements (SIGTTO)

What solution do you go for if you are building today?

How do you assure flexibility for future demands?

What are terminals doing to accomodate the new smaller size of vessels in this local area?

Communication – what will be the standard?

Seagas & Viking Grace have a telemetri system, but this is not a feasible solution for a bunker vessel offering open access LNG bunkering.

Ruels & regulations for Methane Slip -Ongoing discussions, but right now thereare no requirements to relate to and weare building right now.

Challenges along the way so far - examples

What is going on right now:

• Yard proposal of maker - Owner selection of maker

• Manufacturing of the cargo tanks

• Engineering of all medium system.

• Engineering of all block sections

• Continues calculation of lightweight and stability

• Temperature calculations for cargo voids

• Torsional calculations

• Stress analyses

• Planning for makers FAT´s

• Progress meetings both with yard and main supplier TGE

• P&ID´s meetings with both yard and main supplier TGE

• Continues 3-D analyze of the Engineering process

PILOT LNG – Activity 2: Status, where are we today with JIP FLEXI?

Next step:

• Keel laying before end 2015

• Establish the site team at the yard

• Continues engineering and construction

Expected delivery of the vessel is scheduled for end year 2016

This is only the beginning. As the work to establish an

infrastructure for LNG as a alternative marine fules

continues, it is important to create a system with

rules and regulations that gives support and clear directives.

Shared knowledge, cooperation towards the same goals, an open dialogue – all are key ingredients to make this work!

Thank you for your time!
