REVISIONS TO THE MARITIME SINGAPORE GREEN INITIATIVE (MSGI) – INTEGRATION

OF GREEN PORT PROGRAMME (GPP) INTO THE ENHANCED GREEN SHIP

PROGRAMME (GSP) FOR OCEAN-GOING VESSELS

This circular supersedes Port Marine Circular No.10 of 2022 and will take effect from

1 January 2025 until 31 December 2027.

2 The MSGI has been enhanced to better align with the targets established by the

International Maritime Organization (IMO) to achieve peak greenhouse gas (GHG) emissions

from international shipping as soon as possible, and to guide the industry towards reaching

net-zero by or around 2050.

3 Under the revised MSGI, with effect from 1 January 2025, the current GPP will be

integrated under the enhanced GSP – Green Port. The existing incentives for harbour craft

under GPP will be subsumed under a new Green Craft Programme (GCP). Details will be

provided in Port Marine Circular No. 15 of 2024.

[For Ocean-Going Vessels] Key Enhancements to the GSP – Green Port

4 The enhanced GSP - Green Port will continue to incentivise ocean-going vessels

calling at the Port of Singapore for port stays of 4 days or less – with vessels meeting either

of the following criteria:

i. Use of zero-emission fuel/technology (e.g. hydrogen, full electrification,

hybrid of hydrogen fuel cell and electrification etc.)

Ocean-going vessels that use zero-emission fuel/technologies as its primary fuel

or propulsion means will enjoy 100% concession off the port dues for eligible vessel

call.

ii. Use of zero-carbon fuel (e.g. ammonia with pilot fuel capped at 25% with

ammonia slip/NO /N O addressed, B100 biofuel, green methanol etc.)

x 2

Ocean-going vessels that use zero-carbon fuels will enjoy 100% concession off the

port dues for eligible vessel call.

iii. Use of low-carbon content fuels with C value1 ≤ 1.375 (e.g. Methanol), or

F

using LNG in engine with methane slip addressed to max 1%, or biofuels B50

and above up to B99.

Ocean-going vessels that use relevant low-carbon content fuel as its primary fuel

will enjoy 30% concession off the port dues for eligible vessel call.

iv. Use of low carbon content fuels with 1.375 < C value ≤ 2.750, e.g. LNG (in

F

engine without methane slip addressed), or biofuels B24 and above up to

B49.

Ocean-going vessels that use relevant low-carbon content fuel as its primary fuel

will enjoy 20% concession off the port dues for eligible vessel call.

5 To participate in the GSP - Green Port, shipowners or charterers should ensure that

their vessels are pre-registered under the GSP – Green Port via digitalPORT@SGTM prior to

arrival at the Port of Singapore. A step-by-step guide for registering of vessels under the

programme can be found in Annex I of this circular.

6 For each arrival call at the Port of Singapore, the vessel shall declare its participation

in the GSP – Green Port in the Pre-Arrival Notification form (“PAN”).

Existing vessels under the current GPP

7 Currently registered ocean-going vessels under the existing GPP will not be

automatically enrolled in the GSP – Green Port. Vessels must re-register to qualify for the new

incentives under the enhanced GSP - Green Port.

Terms and Conditions of the GSP - Green Port

8 Participants in the GSP – Green Port are advised of the following terms and conditions:

i. The GSP – Green Port is only valid for ocean-going vessels calling at the Port of

Singapore.

ii. To qualify for the port dues concession, the vessel must adhere to a port stay of 4

days or less.

iii. To enjoy the applicable port dues concession, the master or agent of the registered

vessel must declare the same selected criteria under GSP – Green Port during

registration in the PAN for each applicable port call. It is the vessel’s agent or

charterer’s responsibility to inform the master of the selected criteria. There will not

be any retrospective adjustments made.

iv. Vessels using zero-emission technology must initiate the switch to zero-emission

technology for the main engine and auxiliary engine(s) before entering Singapore

Port Limits if not already done so. The use of such technology must be maintained

throughout the port stay to qualify for the concession (i.e. no switching from zero-

emission technology at anytime while within Singapore Port Limits). The switch

from zero-emission technology must only be initiated after exiting Singapore Port

Limits.

v. Vessels using zero- or low- carbon fuel must initiate the switch to zero- or low-

carbon fuel for the main engine and auxiliary engine(s) before entering Singapore

1 C value refers to a non-dimensional conversion factor between fuel consumption (measured in g)

F

and CO emission (measured in g based on carbon content).
