Climate Adaptation Report published by the UK Canal & River Trust

Recently published, a new report produced by the Canal & River Trust aims to show how vital the UK’s waterway network can be as the Government tries to tackle climate change. The 30-page Climate Adaptation Report spells out how important canals and waterways are and how they can be part of action against problems such as storms, flooding and drought, which have badly affected areas of the UK.

It highlights how the 2000 miles of canals and waterways, and 84 reservoirs, across England and Wales have adapted from their original roles and can now become a vital infrastructure as the country deals with climate change threats.

The Climate Adaptation Report also claims the charity will need an extra £15 million a year to combat global warming. Continue reading “Climate Adaptation Report published by the UK Canal & River Trust”

Silicone-based hull coatings to deliver significant emissions reduction according to Maritime Emissions Reduction Centre analysis

New analysis by the Maritime Emissions Reduction Centre (MERC) has found that silicone-based hull coatings could deliver significant emissions reductions, but challenges around application and mechanical strength remain.

Silicone coatings, with their very low surface energies and smooth surfaces, result in self-cleaning properties that release microfouling, preventing the development of macrofouling. The resulting reduction in drag can lead to significant fuel savings and lower greenhouse gas (GHG) emissions. While manufacturers claim potential fuel savings of up to 10%, the analysis by MERC of actual vessel performance reported by its members provides a more nuanced picture of the technology’s benefits. Coating performance is highly dependent on factors such as vessel type, age and operating profile. While substantial savings are possible, precise performance measurement remains challenging due to variables such as engine condition and weather.

Danish Shipping has adopted a new policy on biofouling management, where it recommends that its members follow IMO guidelines, which are currently not mandatory.
So-called biofouling on the hulls of ships is not only a potential threat to vulnerable marine ecosystems, but it also causes increased fuel consumption, when there are things stuck to the hull (due to the increased friction).
Proper biofouling management reduces fouling, bio-security risks and fuel consumption. Danish Shipping recommends its members follow IMO guidelines and keep records of their adherence to the guidelines. Continue reading “Danish Shipping adopts biofouling management policy”

ITOPF oil tanker spill statistics 2024 report

Ten oil spills of more than seven tonnes were recorded from tanker incidents in 2024, the same number as in 2023.
This brings the decade average to 7.4 tanker spills per year, which is a dramatic reduction from the numbers reported in earlier decades but currently slightly higher than the average for the 2010s (6.3 spills per year).
The total volume of oil lost to the environment from tanker spills in 2024 was approximately 10,000 tonnes.
Most oil spills (>7 tonnes) recorded between 1970 and 2024 were caused by allisions/collisions and groundings.
ITOPF maintains a database of oil spills from tank vessels, including combined carriers, FPSOs and barges. This contains Continue reading “ITOPF oil tanker spill statistics 2024 report”

DNV: How to identify false sulphur emissions readings

vessels have encountered unexpected port state issues related to sulphur emissions limit exceedance
Vessels have encountered unexpected port state issues related to sulphur emissions limit exceedance

An increasing number of vessels have encountered unexpected port state issues related to sulphur emissions limit exceedance caused by inaccurate readings. These false measurement readings are often the result of poorly maintained exhaust gas analyzers. Classification DNV has guidance on the importance of calibration and maintenance routines, and of monitoring equipment performance.

Introduction
Malfunctions of SOx scrubbers or exhaust gas cleaning systems (EGCSs) that last more than one hour should be reported to the flag administration and the relevant port state administration. However, sometimes a malfunction may go undetected because the monitoring equipment does not register any increase in SO2 concentration. Often, the cause of false measurement readings is poor maintenance. Continue reading “DNV: How to identify false sulphur emissions readings”
