Summary
• Abt. 20 LNG bunker vessels will be in operation (2021)
• The geographical footprint of LNG bunker vessels has drastically increased
• STS transfer operations with different types of vessels and systems are gaining significant operational experience
• Standardization needs to be driven and future bunker vessels can be built simpler and cheaper as ‚first followers‘ in
geographical areas with existing bunker vessels
• Alternative fuels are slowly entering into the market -> adaptation of bunker vessel design is required

SGMF Guidelines SGMF published guidelines in

Linked ESD systems now called ‘Bunkering Safety Links’• Type 1 BSL:
• Pneumatic – ESD only
• Type 2 BSL:• Electric (SIGTTO link) – ESD only
• Type 3 BSL:• Fibre optic – ESD, Telecoms, Data• Radio – Future?
Trelleborg Marine Systems2
Type 1: Pneumatic Link Basic system Air Supply Regulator Restrictor Pressure Switch Solenoid Valve
Problems in timing and repeatability
Base concept for use with trucks
Trelleborg Marine Systems3
Type 2: ESL (SIGTTO Link) Simple ESD link
Master includes an interposing relay stage
Slave provides an i.scurrent to drive the relays Loss of current trips both
sides of the link
TRELLEBORG GROUP
Type 3: Fibre Optic USL
TRELLEBORG GROUP
Very simple interconnection ESD Telecoms Process data IAS
USL controller handles the signal conversion
Single operator interface for all links
Conclusions Bunkering Safety Links are standard
• Use the guidance available
Not every application will use the full fibre solution, but as an important stakeholder, you can strive for the highest levels of safety
Bunker suppliers need to consider their LNG source compatibility
Speak to us if you need any additional information• More project are going live all the time, ask if you need to confirm any
details• It’s our job to make this simple for operators, but we need the feedback
from operators to improve, especially if there are problems
