Shell Marine acquires IMPA accreditation

Shell Marine acquires IMPA accreditation
Alfa Laval Equipment Upgrade AFEM for Smit inert gas systems

Shell Marine has become the first company involved in the development, supply and support of marine lubricants to receive accreditation under the International Marine Purchasing Association’s IMPA ACT sustainable maritime suppliers scheme.

The preferred supplier status is conferred within the IMPA responsible supply chain management (RSCM) initiative which seeks to improve the economic, social and environmental sustainability of international shipping and marine industries.

“We, at Shell Marine, are delighted to be the first in our sector to secure accreditation under the scheme,” said Jan Toschka, Shell Marine executive director. As a global supplier with more than 30 blending plants and a maritime supply network of more than 700 ports in 58 countries, anyone visiting or working with Shell Marine will know how seriously we take our responsibilities as a world citizen.

“However, we also realise it is imperative that our own strict code of ethics is fit to stand up to the scrutiny of external parties. That is why we see this recognition under the IMPA ACT scheme as particularly important. Our customers also confirm that the IMPA ACT preferred supplier status is being used as a benchmark for quality throughout the supply chain.”

Members are leading shipowning and management companies with a commitment to implementing the IMPA ACT Supplier Code of Conduct both within their company and through their supply chain. Preferred supplier accreditation is awarded to organisations that meet the IMPA ACT standards or reach agreed milestones, in a process that is fully audited by IMPA and may be subject to spot checks.

“IMPA ACT is an exclusive community of ship purchasers and suppliers working to become sustainability frontrunners by working towards compliance with internationally endorsed standards,” said Stephen Alexander, IMPA secretary general and chief operating officer. “It is an independent initiative representing international best practice and is aligned with UN principles.”


Babcock LGE Process presented with LR Approval in Principle

Babcock International Group subsidiary Babcock LGE Process received Approval in Principle (AiP) from Lloyd’s Register (LR) at this year’s Gastech conference and exhibition for its liquefied natural gas (LNG) mixed refrigerant reliquefaction system, ecoSMRT.

With innovation at the heart of its market-leading philosophy, Babcock said that it was delighted to receive AiP for its new technology, which recognises its successful assessment against demanding industry codes and standards.

Designed in response to the growing requirement for a solution to the problem of excess boil-off gas resulting from the introduction of dual-fuel propulsion engines with high efficiency, the ecoSMRT LNG reliquefaction plant is designed for application on LNG carriers to save excess boil-off gas by means of its reliquefaction.

“We are pleased to present the AiP certificate to representatives of Babcock here today at Gastech,” commented Jose Navarro, principal gas technology specialist for LR. He continued: “There is lots of discussion at the show around efficiency, so it is very fitting to be able to recognise Babcock’s LNG reliquefaction system, ecoSMRT.”

The scalable ecoSMRT system, optimised for LNG carriers, uses the well-proven and reliable technology of mixed refrigerant refrigeration, but is based on a novel arrangement of these components. The improved single mixed refrigerant LNG reliquefaction system reduces complexity, minimises overall footprint and reduces cost in terms of initial investment as well as during operation.

Alan Duckett, technical and sales director for Babcock LGE Process, said: “As innovators in the field of LNG technologies it is a real privilege for Babcock to be recognised in this way and to be presented with an AiP from LR.

“Our ecoSMRT technology can provide significant operational benefits to LNG carriers and is testament to our ground-breaking design capabilities, developed along with long standing partner Hyundai Heavy Industries and with valuable input from LR.

“It is an exciting time for Babcock, as we introduce new technological solutions for LNG carriers as well as shuttle tankers – ecoVOCC – and LNG gas supply vessels – FGSVo.”

The presentation by LR closely followed the announcement that Babcock LGE Process would bring its award-winning innovation and extensive international experience to bear in a collaboration with ExxonMobil, Bernhard Schulte Shipmanagement, Calor Gas and Orkney Islands Council in the Caledonia LNG project, that will explore the provision of LNG for northern UK and North Sea customers.

With a track record of success in Asian markets, where Babcock has developed cutting edge solutions for its clients – including ecoSMRT and its patented Vent Gas Cooler, SuperCooler and FGSVo technology – the company brings an unrivalled depth of knowledge and skill to LNG operations.


Alfa Laval AFEM produces significant fuel savings

The Alfa Laval Automatic Fuel Efficiency Module (AFEM) is a new modification for reducing the fuel consumption of Alfa Laval Smit Combustion inert gas systems. It does so by ensuring the inert gas that keeps cargo safe during offloading is only generated in the exact amounts required. In a two-year pilot project, the AFEM enabled Italian shipping company Navigazione Montanari to achieve an average fuel saving of 30 per cent.

Valle di Navarra, a 40,000 dwt product carrier built in 2002, was selected as the test vessel for the project. The ship generally sails in the Mediterranean, with gas oil and gasoline cargo. Compared with similar vessels with Smit Combustion systems, Valle di Navarra discharges frequently – up to three times per week. This provided Alfa Laval with ample statistical information on the AFEM’s performance and reliability. 

Data collection was one reason that Alfa Laval decided on a particularly long pilot programme, but guaranteeing the cargo’s safety and reliable availability was even more crucial.

“The AFEM modification is part of the inert gas generator’s combustion control circuitry,” said Mart Blankert, inert gas systems customer support manager at Alfa Laval. “A failed module could prevent cargo from being discharged, meaning expensive delays in port. Working with potentially volatile cargo, we took our time with the pilot to ensure that everything functioned as intended.”

“The AFEM was designed with capabilities for full override in case of any such problems,” added Alessandro Federico, Navigazione Montanari technical director. “And although you expect some issues with any pilot project, we are glad to say that we never lost a minute of commercial operation with the AFEM.”


Chevron expands oil analysis into China

Chevron Marine Lubricants has cemented its commitment to the Asian market by expanding its FAST used oil analysis service into a new laboratory in mainland China. This offers the ability to analyse FAST and drip oil analysis DOT.FAST samples with a faster turn-around for vessels visiting Chinese ports.

Testing is conducted by SGS, Chevron’s lubricants analysis partner, in a state-of-the-art laboratory in Shanghai, with the same test procedures and operational excellence standards that Chevron’s customers have come to expect, according to the company. The new location provides the same format of testing, reporting and commenting while using a common database that ensures access to Chevron’s FASTWeb for historical trends and results, no matter where the sample was tested.

“We continue to grow our world class lubrication services, designed to help our customers maximise efficiency on board,” said Chia Yoo Soon, general manager of Chevron Marine Lubricants. “This demonstrates our focus on customer requirements and our ability to adapt to their needs quickly. The introduction of FAST testing facilities in China will significantly reduce the time taken for samples to be delivered to existing laboratories, meaning faster results and improved onboard monitoring.”
