DNV offers guidance on the matter of corrosion in ballast water & cargo tanks, highlighting that the actual corrosion rate may differ, with factors like temperature and coating condition playing significant roles in the deterioration process.
According to DNV, the actual corrosion rate in ballast and cargo tanks may differ from the assumptions in the rules and the embedded corrosion models. DNV survey data reveals a significant rise in corrosion findings in water ballast and cargo tanks in oil tankers and bulk carriers at the third renewal survey, with a peak at the fourth renewal. That means that for some vessels, Continue reading “Corrosion in ballast water & cargo tanks”
As the offshore wind sector across the world witnesses growth, there is a rise in safety concerns for personnel and vessels involved. Last week, the G+ Offshore Wind Health and Safety Organization released its 2024 incident report, revealing rising safety risks in the offshore wind industry.
The data contained in the report is compiled from G+ member companies, comprising lead operators and owners of offshore wind farms Continue reading “Safety risks highlighted in the rising offshore wind industry”
In the vast expanses of the world’s oceans, a silent yet pervasive threat is taking shape: plastic nurdles. These tiny, pre-production plastic pellets, measuring between 2 to 5 millimeters in diameter, are fundamental to the plastics industry, serving as the building blocks for a myriad of plastic products. However, their small size belies the significant environmental and potential health hazards they pose. Continue reading “It’s time for shipping to properly regulate plastic nurdles”
The Norwegian Government introduces zero-emission requirements in the World Heritage fjords. In a circular the Norwegian Maritime Authority (NMA) confirmed the changes will be effective from 1 January 2026 for passenger ships of less than 10,000 gross tonnage and from 1 January 2032 for passenger ships of 10,000 gross tonnage and upwards. Continue reading “Norwegian Government introduces zero-emission requirements”
The IMO Marine Environment Protection Committee (MEPC) 83 session was held from 7-11 April 2025. The IMO MEPC is where the reduction of shipping’s impact on the marine environment is discussed. MEPC oversees the work of several sub-committees and influences subjects which cut-across the work of several committees, covering many key regulations.
And Lloyd’s Register has published a summary of the outcomes from the meeting. Continue reading “Lloyd’s Register summary report on MEPC 83”
The Nautical Institute is proud to support the Maritime Technologies Forum’s (MTF) initiative in developing the Guidelines for Developing and Implementing a Safety Management System for Ammonia-Fuelled Ships. This document is a critical first step in addressing safety gaps associated with the use of ammonia as a marine fuel, providing industry stakeholders with a structured approach to integrating safety measures within their Safety Management Systems (SMS). Continue reading “Guidelines for developing an SMS for Ammonia-Fuelled Ships”
Lloyd’s Register (LR) has issued an update to its Retrofit Research Programme, with the latest report focusing on the developments in Engine retrofits for alternative fuels and the lack of green fuels in engine retrofits.
While the maritime industry has seen positive developments, such as increased methanol fuel conversions and shipyard engine retrofits capabilities since 2023, the adoption of alternative fuels faces a significant hurdle. Continue reading “Lack of green fuels in engine retrofits says new study”
The International Marine Contractors Association (IMCA) has expressed serious concerns over the UK Maritime and Coastguard Agency’s (MCA) proposed implementation of the International Maritime Organization’s (IMO) Industrial Personnel Code which could put UK offshore wind targets at risk.
In its response to the MCA’s consultation on the Merchant Shipping (Safety Measures for Ships Carrying Industrial Personnel and Special Personnel) Regulations 2025, IMCA warned that the changes could disrupt offshore operations, attract legal challenges, and make the UK a less attractive market for marine contractors. Continue reading “UK offshore wind targets at risk from UK Implementation of Industrial Personnel Regulations”
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”
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. Continue reading “Silicone-based hull coatings to deliver significant emissions reduction according to Maritime Emissions Reduction Centre analysis”
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”
