Marine fuel testing firm VPS on Monday (7 August) delivered an update on the recent VLSFO marine fuel contamination in Houston, revealing out of 14 vessels, two vessels were supplied with contaminated fuel oil in Singapore and 12 vessels received it in Houston.

On 10 July, VPS informed its customers and the wider market, of the presence of Dicyclopentadiene (DCPD) isomers at significantly high levels within VLSFO bunker fuel deliveries in Houston. The contaminants were detected using in-house GC-MS (Gas Chromatography – Mass Spectrometer) analytical methodologies.

Initially, VPS highlighted eleven vessels had suffered operational issues, such as loss of power and propulsion whilst at sea. These effects resulted from fuel leakage in the ICU (Injection Control Unit) units and fuel pumps not being able to develop the required fuel pressure, affecting only the Auxilary engines and not Main engines. The contaminated VLSFO had been delivered in Houston, by one single fuel supplier.

Four weeks later, VPS can now provide a further update on the spread of this fuel contamination issue: Fourteen vessels in total, have now received this contaminated fuel and suffered some form of damage to their auxiliary engines and fuel delivery systems. Twelve of the vessels received their fuel in Houston, whilst a further two vessels received their fuel in Singapore, with the fuel delivered by four suppliers.

The specific contaminants are:

Di-hydro dicyclopentadiene
Chemical CAS Number: 448-57-7
Tetra-hydro dicyclopentadiene
Chemical CAS Number: 6004-38-2

DCPD’s are unsaturated chemical compounds which can polymerise and oxidise under certain conditions. However, the rate of this polymerisation process can be reduced by the presence of inhibitors that are typically found within fuel oil.

Should these compounds start polymerising, the fuel begins to exhibit a level of stickiness and become more viscous, making it difficult for moving components, such as fuel pump plungers and the fuel injector spindles to move freely. These effects cause damage to the fuel injection system.

Over a period of time excessive sludge formation is likely to be experienced. The DCPD compounds that were detected in this fuel ranged from 3,000 to 7,000 ppm (0.3-0.7%) per delivery.

VPS employed it’s own proprietary GCMS Vacuum distillation methodology to detect DCPD, in preference to the ASTM D7845, Standard Test Method for Determination of Chemical Species in Marine Fuel Oil by GCMS. The VPS methodology is capable of detecting and measuring the DCPD and its isomers, whereas the ASTM D7845 methodology is limited to detecting only 29 chemical contaminants, which does not include DCPD species.

In addition to the fourteen vessels suffering damages from burning this fuel, a further 18 vessels who received the contaminated fuel from thirteen additional suppliers, either witnessed no adverse reactions, or simply did not provide any feedback regarding any damages.

In total, the volume of contaminated fuel delivered to the 32 vessels, was 61,494 metric tonnes. Three vessels de-bunkered the contaminated fuel prior to burning, following a “Caution” result from the VPS Chemical Screening service, highlighting the value of this pre-burn service.

A further three vessels de-bunkered the fuel after suffering initial engine damage from burning the fuel. Whilst another two vessels burnt the fuel in their main engines without issue after switching it from their auxiliary engines, where it had caused operational damage.

China launched its first training platform to simulate methanol bunkering operations at Putuo District, Zhoushan on 15 January.

The Methanol Bunkering System Simulation Training Platform V1.0 was created to fill technical gaps in domestic methanol bunkering training and exercises, in light of the growing demand and popularity for methanol in the shipping industry.

Through the real-life simulation, the platform helps ship operators improve their safety management and emergency response capabilities, improving the development of green shipping technologies.

The platform was jointly developed by Zhejiang Ocean-U New Energy System Engineering and Zhejiang Ocean University.

At the press conference , Zhejiang Ocean-U New Energy System Engineering successfully signed its first purchase agreement with Seacon Ships Management (Zhejiang), making Seacon the first customer to purchase the platform service.

Wang Guofeng, chairman of Seacon, said that the platform has great potential in improving crew operating efficiency and safety, and he looks forward to deeper cooperation with Zhejiang Ocean-U New Energy System Engineering in the future.

Professor Lu Jinshu, Vice President of Zhejiang Ocean University, said they will continuously improve the platform to contribute more in the field of green shipping solutions to the industry.

Klaipėda Port launches Lithuania’s first hydrogen-powered vessel

Tanker’s power system, which will consist of two electric motors powered by 2,000 kWh batteries and a hydrogen fuel cell system, will enable it to operate for up to 36 hours without additional power charging.

Klaipėda Port launches Lithuania’s first hydrogen-powered vessel

Klaipėda State Seaport Authority on Wednesday (22 January) said the first ever green hydrogen and electricity-powered ship in Lithuania has been moved from shipyard into water.

Leaving no trace on the environment, it will clean other vessels entering the port, accepting waste from them.

According to the current rules, vessels are obliged to hand over the waste they produce when they arrive and before they leave Klaipėda Port. The Seaport Authority was entrusted with the collection of the waste, and the company decided to use modern and environmentally friendly equipment to further improve the quality of the ship waste collection service.

The tanker’s main function is to collect storm water, sewage, sludge and garbage, as well as to ensure efficient waste management. The ship will be equipped with special tanks and a modern rainwater treatment plant that will allow the treated water to be transferred to the city’s sewage treatment plants. The tanker will be ready to work around the clock and collect up to 400 cubic metres of liquid waste.

The tanker is 42 metres long and 10 metres wide. The ship’s power system will consist of two electric motors powered by 2,000 kWh batteries and a hydrogen fuel cell system. Depending on the intensity of the work, the tanker will be able to operate in the port of Klaipėda for up to 36 hours without additional power charging.

This ship building project with a total value of EUR 12 million (USD 12.5 million) has been commissioned by the Port Authority and is being built by West Baltic Shipyard together with Baltic Workboats under a joint operating agreement.

“We have not only launched a tanker, but also a new approach to port operations – cleaner, smarter and more environmentally friendly. This first ever hydrogen and electricity-powered ship is not only an innovative technological solution, but also an important step in strengthening Lithuania’s image as a modern maritime nation,” said Algis Latakas, Director General of Klaipėda State Seaport Authority.

“At the moment, the tanker is getting used to the seaport water, so to speak, and at the end of the year we expect it to start its important mission of taking care of the clean seaport environment. Such a decision will not leave a footprint on nature, but it will certainly leave a strong mark on our path to a greener future.”

In June last year, a symbolic keel-laying ceremony at the West Baltic Shipyard of the West Baltic Shipyard Group marked the start of the ship’s construction. To date, the hull has been fabricated and painted, with piping, valves, coolers, shaft lines, rudder feathers, heat and fire insulation installed.

Once the tanker is moved into the water, the engine room equipment will be installed, the interior of the wheelhouse will be redecorated, the electrical wiring and the main electrical engines will be installed, the hydrogen system will be installed and other work necessary for the operation of the ship will be carried out.
