Viswa Group gives update on bunker fuel issues in Houston

Presence of polyester compounds in bunker fuel can accelerate corrosion of fuel system components, resulting in equipment damage, leaks, and potential safety hazards.

The Viswa Group, a firm that offers marine fuels testing, on Wednesday (19 July) released an update, dated 13 July, on its investigations into fuel pump problems related to the recent Houseton bunker fuel issues:

Viswa has conducted thorough investigations into fuel pump problem samples bunkered in Houston, and we would like to provide a more detailed update on these fuel pump issues.

All three samples originated from a single supplier. The vessel experienced fuel pump malfunctions and corrosion problems. These fuels have a high sediment content and demonstrate poor storage stability properties. Through GCMS-CRA analysis of these samples, we identified the presence of various compounds, including 2-Ethylhexanol, DHDCPD, Tetrahydro-DCPD, Tetrachloroethylene, and Ethylene glycol, each at different levels. While DHDCPD and Tetrahydro-DCPD showed the highest concentrations, it is important to note that we have tested other VLSFOs with high concentrations of these compounds, and they did not result in any issues.

The recent Houston bunker fuel problem case was specifically associated with samples containing the combination of contaminants mentioned above. At elevated temperatures within the fuel pump, a chemical reaction between the Glycol compounds and DCPD compounds can occur, leading to the formation of polyester compounds. The presence of these components in bunker fuel can accelerate corrosion of fuel system components, resulting in equipment damage, leaks, and potential safety hazards.

Furthermore, we would like to highlight that we received reports of similar fuel pump issues from Singapore and Houston ports last year. These cases also involved the same set and combination of contaminants: 2-Ethylhexanol, DHDCPD, Tetrahydro-DCPD, Tetrachloroethylene, and Ethylene glycol.

To safeguard the machinery and the vessel, we highly recommend utilizing the VLSFO POMP (Peace of Mind Package). This comprehensive  package  includes  long-term storage stability assessment as well as a GCMS screening test which can detect the presence of at least 16 compounds. By proactively implementing this solution, you can identify potential issues and take appropriate measures to prevent fuel pump problems.

Singapore-based Eastern Pacific Shipping (EPS) on Wednesday (28 February) said it signed two new contract orders in a signing ceremony in Shanghai, one for a series of ammonia dual-fuel bulk carriers with CSSC Beihai Shipbuilding and another for a series of LNG dual-fuel oil tankers with CSSC Guangzhou Shipbuilding International. 

The contracts signed cover four 210,000 dwt ammonia dual-fuel bulk carriers and two 111,000 dwt LNG dual-fuel LR2 oil tankers, expanding our fleet of green vessels on water. 

“These are pivotal for EPS, testament to our continued commitment towards the decarbonisation of shipping,” EPS said in a social media post.

Manifold Times recently reported EPS signing a contract for its first ever wind-assisted propulsion system, partnering with bound4blue to install three 22-metre eSAILs® onboard the Pacific Sentinel

The turnkey ‘suction sail’ technology, which drags air across an aerodynamic surface to generate exceptional propulsive efficiency, will be fitted later this year, helping the 183-metre, 50,000 DWT oil and chemical tanker reduce overall energy consumption by approximately 10%, depending on vessel routing.

Port of Tanjung Pelepas Sdn Bhd (PTP), a joint venture between MMC Group and APM Terminals, on Wednesday (28 February) announced a significant milestone with the successful completion of its first Liquefied Natural Gas (LNG) bunkering operation. 

The landmark event involved the CMA CGM Monaco, a 14,024 TEUs (Twenty-foot Equivalent Units) capacity containership operated by French shipping giant, CMA CGM.

Tan Sri Che Khalib Mohamad Noh, Chairman of PTP in a statement remarked this latest milestone demonstrates PTP’s commitment to continuously enhance its competitive advantages in an increasingly competitive global market.

“The successful completion of our first LNG bunkering operation also underscores our unwavering commitment to sustainability and environmental leadership. We are proud to partner with Petronas Trading Corporation Sendirian Berhad (PETCO) and CMA CGM on this initiative and showcase PTP’s capabilities as a leading facilitator of clean and efficient maritime operations.”

“This milestone paves the way for further growth in LNG bunkering at PTP, contributing significantly to the decarbonisation of the maritime industry.”

Commenting on this achievement, Mark Hardiman, Chief Executive Officer of PTP stated this latest milestone further highlights PTP’s position as the largest transshipment hub terminal in Malaysia.

“In preparation for the LNG bunkering operation, PTP worked closely since March 2022 with PETCO and CMA CGM, as well as with various other related government agencies to organise table-top exercises (TTX) and workshops, before carrying out the deployment exercise.”

“The success of the bunkering operation is a result of the seamless collaboration and preparations involving rigorous safety procedures through in-depth operational and risk assessments, modelling, and validation. We thank PETCO, CMA CGM all other involved parties for their joint efforts in operationalising the bunkering capability and we welcome partners to work with us to accelerate maritime decarbonisation,” said Hardiman.

Port of Tanjung Pelepas (PTP) is Malaysia’s largest transshipment hub with the capacity to handle 13 million TEUs annually. The port delivers reliable, efficient, and advanced services to major shipping lines and box operators, providing shippers in Malaysia and abroad with extensive connectivity to the global market. PTP is currently ranked 15th among the world top container ports.

Wallenius Wilhelmsen PCTC order

Roll-on/roll-off (Ro-Ro) shipping company Wallenius Wilhelmsen on Tuesday (27 February) declared options to build four additional next-generation Shaper Class pure car and truck carrier (PCTC) vessels.

The 9,300 CEU methanol dual fuel vessels can utilise alternative fuel sources, such as methanol, upon delivery. They will also be ammonia-ready and able to be converted as soon as ammonia becomes available in a safe and secure way.

“Together with our customers we are committed to further shaping our industry and accelerating towards net zero. These new vessels are a vital part of that journey,” says Xavier Leroi, EVP & COO Shipping Services.

This latest commitment brings the total number of Shaper Class vessels currently on order with Jinling Shipyard (Jiangsu) to eight. Wallenius Wilhelmsen also retains further options.

The first of the Shaper Class vessels already ordered are expected to be delivered in the second half of 2026. The four additional vessels under the declared options will be delivered between May and November 2027.
