Classification society DNV on Friday (2 July) released the latest updates to its rules for ship classification, with a raft of new class notations designed to enable the maritime industry to tackle the decarbonization challenge. The new updates include “Fuel Ready”, a class notation that offers shipowners the option to prepare for a later conversion to multiple different alternative fuel options, and “Gas fuelled ammonia” for ammonia fuelled vessels, to stay ahead of shipping’s ever tightening carbon reduction requirements:

DNV’s annual report on the energy transition in shipping – “Maritime Forecast to 2050” – has identified fuel choice as the most critical decision facing shipowners and operators today.

 Maintaining flexibility in the choice of fuel, especially when the bunkering environment is in flux, can minimize the risk of stranded assets and maintain a vessel’s lifetime competitiveness.

“The whole maritime industry, but particularly shipowners and operators, are facing a great deal of uncertainty around their choice of future fuel,” said Knut Ørbeck-Nilssen, CEO of DNV Maritime. “With the industry under pressure to bend the carbon curve towards zero, inaction is not an option, but picking a future winner in a complicated fuel landscape is a significant challenge. 

“Fuel Ready” gives owners the option to tailor their future conversion with more than one fuel in mind, while “Gas fuelled ammonia” provides a practical path for owners who are looking to move towards a zero-carbon fuel option with their next newbuilding.”he added.

Fuel ready: The “Fuel ready” notation is applicable for ammonia, LNG, LPG and LFL (methanol) as a ship fuel – either individually or for more than one fuel at the same time. 

It is built around two mandatory options, (D) Design and (Ti/Tc) Tank, with basic and optional levels of preparation that offer a simple framework for all involved parties in newbuildings. 

Optional attributes cover the structure, engine and machinery, piping and bunkering, and miscellaneous requirements. With all of the options, owners can choose to prepare for a later installation of any system or go ahead with the actual installation and obtain certification of the system during construction.

Gas fuelled ammonia: Ammonia is emerging as a promising alternative fuel option for shipping to help reduce greenhouse gas emissions. With the “Gas fuelled ammonia” notation, DNV provides owners looking to build ammonia fuelled vessels the option to start today. Currently, owners are faced with the long, challenging, and costly, “alternative design” approach under the SOLAS regulations. 

The new class notation sets out the requirements for the ship’s fuel system, fuel bunkering connection, and on through to the consumers.

DNV has also updated some of its signature class notations that focus on reducing shipping’s overall environmental impact, including: Fuel cell installations, “LFL fuelled” for low flashpoint liquid fuelled engines, the “Silent(E)” notation for underwater noise, and “Quiet” for external airborne noise emissions.

The new notations and rules updates were launched on 1 July, 2021 and enter into force 1 January, 2022. A full description of the rules and links can be found here.

Indonesia to expedite removal of sunken Malaysia-flagged tanker “Silver Sincere”

Vessel sank while carrying about 1,000 mt of waste oil on 12 January 2025; the wreck was discovered in March 2025 and was found to have drifted about 13 nautical miles from its original sinking site.

Indonesia to expedite removal of sunken Malaysia-flagged tanker “Silver Sincere”

Indonesia’s Coordinating Ministry for Political and Security Affairs on Tuesday (14 July) held a cross-agency coordination meeting to expedite efforts in handling the Malaysian-flagged tanker Silver Sincere that sank off Bintan Regency, Riau Islands.

The vessel sank while carrying about 1,000 metric tonnes (mt) of waste oil on 12 January 2025. 

According to authorities, the ship sank within Indonesian waters. After several surveys, the wreck was finally discovered in March 2025 and it was found to have shifted approximately 13 nautical miles from the initial sinking location.

The meeting was aimed to align cross-ministerial and institutional measures to expedite the handling of the Silver Sincere wreck while minimising risks to shipping safety, the marine environment, and national interests.

Deputy for Coordination of State Defense and National Unity Purwito Hadi Wardhono emphasised that the handling of the impact of the Silver Sincere sinking was the first case to be comprehensively coordinated, serving as a model for handling foreign vessels sinking within Indonesian jurisdiction.

Through this cross-sectoral coordination, the government will establish a clear and measurable framework that can serve as a reference for resolving similar cases in the future, while minimising state losses due to environmental pollution, damage to underwater ecosystems and infrastructure, and disruption to shipping lanes.

“The most important thing is to immediately stop and prevent the negative impacts of this ship sinking,” Purwito said.

“Therefore, a coordinating role is crucial, as maritime security governance involves various ministries and institutions with varying authorities, allowing for faster, more integrated, and more effective response,” he said. 

He added that the Silver Sincere was a Malaysian-flagged vessel that sank within Indonesian jurisdiction, and therefore, all handling processes must comply with the provisions of Indonesian laws and regulations.

In the meeting, Prof. Eko Ganis Sukoharsono, representing the SAE Energy Consulting Team, presented the results of an analysis based on 14 observation periods using Sentinel-1 Synthetic Aperture Radar (SAR) satellite imagery. 

The analysis results showed strong indications of a waste oil spill that has resulted in marine pollution, damage to the seabed due to shifting shipwrecks, disruption of coastal ecosystems and fishing grounds, and potentially threatening the livelihoods of fishing communities around the Riau Islands. 

Purwito added these findings further emphasise the importance of accelerating the removal of the shipwrecks to prevent widespread environmental impacts, maintain shipping safety, and avoid the potential for greater state losses.

The meeting brought together representatives of related ministries and institutions including the Ministry of Foreign Affairs, Ministry of Defense, Ministry of Transportation, Ministry of Maritime Affairs and Fisheries, Ministry of Environment, Attorney General’s Office.
