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”

What’s behind the latest spate of boat fires?

IIMS CEO, Mike Schwarz, has been alarmed at what seems to be a growing number of destructive yacht and boat fires incidents reaching his desk since the start of 2025. Mike has been motivated to write this article so he can set out and catalogue some of the higher profile fire incidents, as well as some of the less well publicised ones.

This is an expanded article following the introduction I wrote for the IIMS June News Bulletin on this subject. It may have passed you by, but there seems to have been a string of eye-catching large yacht and boat fires erupting around the world since the start of 2025 with devastating consequences. So, what is behind this surge in yacht and boat fires? Is there a common thread? Not sure yet, is the simple answer. Continue reading “What’s behind the latest spate of boat fires?”

MTF’s report highlights critical safety issues of transporting EV’s

Safe carriage of Electric Vechiles (EV’S)

Greenhouse gas (GHG) emissions are an environmental issue experienced globally, affecting countries and industries. As one of the measures to decarbonise road transportation by reducing GHG emissions from automobiles, car manufacturers have been developing EVs that are powered by lithium-ion batteries (LiB) instead of conventional fuels, which has caused safety issues transporting EV’s.

West P&I Club has issued a loss prevention bulletin in which they describe best practices and give guidelines on cargo tank cleaning and preparation onboard tankers. the Club highlights that product and chemical tankers carry a variety of commodities, often necessitating frequent tank cleaning to prevent a cross-subsequent, off-spec claim. Detailed planning of the tank cleaning is crucial, and the ship’s crew must be informed of the schedule. The extent of cleaning required depends on the properties of the previous cargo, the tank coating, the next cargo’s preloading specifications and the shipper’s requirements.

A systematic approach to maritime risks

Billowing smoke clouds – A systematic approach to maritime risks

Operating a maritime business is inherently risky. This is so for inland commerce, open ocean navigation, and everything in between. Not only are maritime professionals subject to the whims of Mother Nature, but much of the work itself is dynamic, involving massive vessels, heavy machinery, and hazardous materials. Accordingly, anyone engaged in the maritime industry – from deckhands, machinery operators, and engineers to captains, shoreside support staff, and corporate officers – must be ready to respond to a crisis at a moment’s notice. Because an ounce of preparation is worth a pound of cure, leaders of maritime businesses should expect that crises will occur and train their workforce for the inevitable, a systematic approach is needed to maritime risks.

Understanding liquefaction and dynamic separation in solid bulk cargoes

Understanding liquefaction and dynamic separation in solid bulk cargoes

A recent INTERCARGO report highlighted cargo liquefaction as the greatest contributor to loss of life at sea in the preceding decade. Despite improved safety, cargo liquefaction incidents continued to occur. Although ship losses due to cargo liquefaction accounted for less than 20% of all vessel casualties during that period, they resulted in the loss of 70 lives, representing over 60% of the total fatalities. In other words, if cargo liquefaction occurs on a bulk carrier, it is more likely to result in loss of life than any other type of incident. It is important we have an understanding in liquefaction and dynamic separation in solid bulk cargoes. Continue reading “Understanding liquefaction and dynamic separation in solid bulk cargoes”

Engine room fires are still a major concern

Gard saw five fires originating in the main and auxiliary engines in the first month of 2025 alone. Tragically, some of these engine room fires resulted in fatalities and serious injuries to seafarers. While it is too early to draw any conclusions about how the rest of the year will go, it may be helpful to review experiences from recent years. Although the main cause of these fires may not be identical, there are certain similarities in the underlying patterns of the fires. Every year fires on board ships lead to loss of lives and severe damage to the vessels themselves. Most fires on board ships originate in the engine room Continue reading “Engine room fires are still a major concern”

How to develop a safety culture

The UK Maritime and Coastguard Agency (MCA) has published a section in their Leading for Safety guidance, looking at why accidents happen, what really causes them and what can be done to develop a safety culture in an organisation.

Safety culture describes the way in which safety is managed within an organisation. It relates to the beliefs and attitudes, values, and perceptions that employees share regarding safety in the organisation. According to the MCA, to reduce the rate of incidents, we need a good understanding of: Continue reading “How to develop a safety culture”

Things surveyors cannot find

Sunset over a harbor – Things a surveyor cannot find

The marine surveying industry has changed dramatically over the almost 50 years we’ve been boating. Back in the early days there were not any standards or certifying organizations for surveyors and still rules are adapting to thing surveyors cannot find. Those that had industry experience and connections just ‘hung out their shingle’. Some were very good and some were very bad! Continue reading “Things surveyors cannot find”

Coal Cargoes: Avoiding Explosion and Self-Heating

Coal cargoes

Coal is a fossil fuel with varying properties, depending on its source and handling before it is loaded aboard ship. Some coals can self- heat, and some emit methane – characteristics that can create fire and explosion risks to the crew, vessel and cargo making coal cargoes dangerous.

Røyset said that Gard had seen several cases involving problematic coal cargoes, particularly those originating in Indonesia. She said that her particular focus in this article was how to deal with a cargo Continue reading “Coal Cargoes: Avoiding Explosion and Self-Heating”

Transporting Li-ion batteries: identifying and addressing the risks

The international transportation industry has been looking carefully at the hazards inherent in transporting lithium- ion (Li-ion) batteries and goods powered by them. As has been highlighted recently in the industry press, while Li-ion battery fires are not a common occurrence, their consequences can be devastating.

It has been reported by a major insurer in its 2023 Safety and Shipping Review that battery fires on vessels remain one of the biggest safety concerns Continue reading “Transporting Li-ion batteries: identifying and addressing the risks”

Do you know when fire protection systems onboard should be inspected?

All fire protection systems onboard and appliances should at all times be in good order and available for immediate use while a ship is in service. A helpful recent Marine Notice by the Palau Ship Registry highlights and gives guidance about the requirements of their inspection regime.

Fire protection systems need to be inspected weekly, monthly, quarterly and annually, as follows to ensure proper functioning. Continue reading “Do you know when fire protection systems onboard should be inspected?”
