Tribology in Marine Diesel Engines

, 2022
This chapter deals with the tribology of marine diesel engines. Several types of diesel engines have been installed and used in the engine room of marine ships. Some of them, used for propulsion, operate at low-speed in a two-stroke combustion process in conjunction with propellers.

Optimal Hedging Strategies in the Low‐Sulphur Bunker Fuel Landscape

European Financial Management, EarlyView.
ABSTRACT The IMO2020 regulation for the green transition in shipping turned the industry into using two compliant bunker fuels: very low‐sulphur fuel oil (VLSFO) and low‐sulphur marine gas oil (LSMGO). VLSFO futures contracts introduced in late 2019 and other energy‐related futures contracts indicate that the VLSFO contracts trading on the Singapore ...

Genomic analyses of giant kelp reveal restricted connectivity across the Southern Hemisphere and striking diversity in Aotearoa (New Zealand)

Journal of Phycology, EarlyView.
Abstract The macroalga Macrocystis pyrifera (“giant” or “bladder” kelp) plays a vital role in cold‐temperate marine ecosystems but faces increasing threats from ongoing environmental change. Understanding its population diversity and connectivity is essential for predicting future range shifts and assessing the ecological consequences of such shifts in

Microbial Strategies for the Degradation of Spent Lubricating Oil: A Comparative Study of Isolate Bacterium and Consortium Cultures

Water and Environment Journal, EarlyView.
This show the biodegradation of spent lubricating oil by Bacillus sp. and a marine bacterial consortium. The consortium showed higher growth, biosurfactant production and oil removal efficiency than the isolated strain, highlighting its potential for bioremediation ABSTRACT Spent automotive lubricating oil contains complex hydrocarbons and heavy metals,

Do Voluntary and Mandatory Clean Truck Programs Improve Air Quality Around Ports?

Journal of Business Logistics, Volume 47, Issue 4, October 2026.
ABSTRACT States and port authorities have implemented “Clean Truck” programs (CTPs) to encourage trucking companies to transition to newer, cleaner trucks to reduce the emissions around ports. We examine the comparative effectiveness of mandatory and voluntary CTPs implemented across major United States ports.
