The Danish government has announced a regulation that will ban the discharge of ship wastewater from open exhaust gas cleaning systems (scrubbers) into Danish territorial waters from 1 July 2025. Scrubbers are used to comply with the limit value for the sulphur content of exhaust gases set by the International Maritime Organisation (IMO) in 2020. Such exhaust gas cleaning systems use a chemical solution (seawater and caustic soda) to "wash" sulphur out of the flue gases. The wash water then contains heavy metals (mercury, lead, arsenic, etc.), nitrates, polycyclic aromatic hydrocarbons (PAHs) and sulphur: a toxic mixture that changes the pH value and makes the water acidic! Because there is no further purification step in open systems,...

Current fire extinguishing systems are inadequate for fighting engine room fires involving methanol-based engines, according to a new fire safety study. Engine fires Against the background of the growing interest in methanol as an alternative marine fuel, the study by the British company SURVITEC, a global provider of survival technologies, carried out extensive and comparative fire tests on marine engines fuelled with both diesel oil and methanol. The tests confirmed that conventional water mist firefighting systems do not provide the expected extinguishing performance on methanol fires. If conventionally fuelled ships are to remain safe, a new approach is needed, according to the product manager for water mist systems at Survitec. Bilge fires The tests also showed that standard extinguishing systems...

The UK North Sea Transition Authority (NSTA) has once again awarded exploration licences to companies in a new oil and gas licensing round after October 2023. The successful licence holders include the British offshore majors bp, the Norwegian group Equinor and TotalEnergies E&P UK. The exploration areas now awarded are located in the central and northern British North Sea and west of the Shetland Islands. This is also where the Victory gas field is located, for which Shell received the development and production licence from the NSTA at the beginning of the year. The licences will only be confirmed once the associated environmental and habitat assessments have been carried out by the British...
