Chemical interaction risks and anaerobic conditions in bilge systems

A hidden chemical interaction in a vessel’s bilge system can turn routine cargo and cleaning operations into a serious toxic-gas hazard. According to an IMCA Safety Flash, hydrogen sulphide (Hâ‚‚S) was detected by portable gas detectors in an open area of the main deck during a vessel’s transit back to port. The gas was traced to certain bilge vents with the suspected source linked to mud loaded for a rig. No personnel were injured or suffered ill health, but the incident exposed gaps in anaerobic conditions in bilge systems cleaning, chemical compatibility assessment and Hâ‚‚S monitoring.

YSEC launches new guidance to support consistency in yacht load line compliance

The Yacht Safety & Environmental Consortium (YSEC), a collaboration between leading classification societies including LR, RINA, ABS, Bureau Veritas and DNV, has published a new Guidance Note for yacht load line compliance, providing practical recommendations to support the consistent application of load line requirements across the sector.

Launched on the Lloyd’s Register stand at the Monaco Yacht Show 2026, the guidance has been developed to help yacht designers, builders, owners, Flag Administrations and marine surveyors navigate areas where interpretation of load line requirements may vary between projects.

Fires on vessels present serious dangers to passengers, crew, and firefighters. They can have significant environmental impact and can affect billion-dollar commerce in busy ports. Marine fires present unique hazards that are incredibly dangerous and challenging incidents for marine firefighters to respond to, including vessel instability, tight onboard spaces, and the need for specialized resources that are not typically available in many ports.

The U.S. Government Accountability Office (GAO), the non-partisan, fact-based arm of Congress, recently published a report highlighting the prevalence of these fires and the Coast Guard’s efforts address them.

WSC calls for governments to close battery cargo safety gap

WSC calls for governments to close battery cargo safety gap

The World Shipping Council (WSC) is urging governments to close a gap in international dangerous goods rules that allows containers carrying thousands of lithium batteries to be transported without carriers being informed of the hazard.

The call comes as battery transport grows rapidly and cargo fires remain a persistent risk at sea.

Global lithium-ion battery deployment in 2025 was six times higher than in 2020, according to the International Energy Agency, with battery demand expected to double by 2030. Latest statistics by insurer Allianz show that a container ship fire occurs every 17 days. Continue reading “WSC calls for governments to close battery cargo safety gap”

WSC data shows one in ten inspected cargo units found with safety deficiencies

WSC data shows one in ten inspected cargo units found with safety deficiencies

More than one in ten cargo units with safety deficiencies, according to data published by the World Shipping Council (WSC).

WSC reported that government authorities in seven countries reported 93,079 unit inspections in 2025 and identified deficiencies in 9,645, a rate of 10.36%. Problems included incorrect documentation, marking and labelling, improper packing and inadequate cargo securing, all of which can increase the risk of cargo damage, container losses and ship fires.

“Finding deficiencies in more than one in ten inspected units is far too high,” said Joe Kramek, President and CEO of the World Shipping Council. “Correct declaration, packing, securing and marking are fundamental safety obligations. When these requirements are not met, people’s lives are put at risk.” Continue reading “WSC data shows one in ten inspected cargo units found with safety deficiencies”

Understanding the updated IMO embarkation and disembarkation guidelines

A gangway refers to a platform, a walkway or a ramp connecting the ship to land or other vessels and is used as a means of safe access for the crew. The gangway must be properly rigged and maintained to prevent accidents or injuries and to counter the movement from tidal streams, swell, cargo operations and surge movements caused by ships in the vicinity.

Legislation

Accommodation ladders and gangways fitted on ships before 01 July 2026 on board ships constructed on or after 1 January 2010, should, to the extent possible, adhere with the IMO circular MSC.1/Circ.1331, Rev.1 – IMO “Revised Guidelines for Construction, Installation, Maintenance and Inspection of means of Embarkation and Disembarkation”. This circular should be referred to in conjunction with the Safety of Life at Sea (SOLAS) regulation II-1/3-9 (Means of Embarkation on and Disembarkation from Ships). Continue reading “Understanding the updated IMO embarkation and disembarkation guidelines”

Do you know why a Ship Structural Access manual is required on board?

Maintaining a ship’s structural condition requires regular surveys and inspections throughout its operational life and the Ship Structural Access Manual is an integral part of this process. These checks help ensure that structural components remain free from damage, such as cracks, buckling, deformation, corrosion, or thickness diminution beyond acceptable limits.

For this reason, suitable means of access to the hull structure are essential, enabling safe and effective overall and close-up inspections, as well as thickness measurements.

Regulation II-1/3-6 of SOLAS, as amended, requires oil tankers of 500 GT and above and bulk carriers of 20,000 GT and above, constructed on or after 1 January 2005, to be provided with means of access in each space within the cargo area and forward spaces.

In early December 2025, local media and the Malaysian Maritime Enforcement Agency (MMEA) reported on a general cargo ship M/V KAYO whose crew were rescued after the vessel sent out a distress signal off Malaysia’s east coast in the South China Sea. The vessel was experiencing heavy listing, with the risk of possible loss of stability and capsizing.

The 15 crew members were later safely evacuated, and it was reported that the vessel carried clay cargo loaded at the port of Lumut. At the time of publication, the incident is subject to investigation by the relevant authorities. Skuld wishes to caution its members and other interested parties that the industry has experienced similar incidents in the past, where vessels carrying clay in bulk from Lumut developed severe listing and subsequently sank, resulting in fatalities. [HOPE (2013) and XIN HONG (2020)] Continue reading “Clay liquefaction: a sticky risk to bulk cargo safety”

Ensure the SMS adequately addresses electrical hazards

The Liberia Maritime Authority has issued a circular to reinforce mandatory safety requirements and operational controls related to electrical hazards onboard vessels, with particular emphasis on the use, handling, relocation, and isolation of portable electrical equipment.

A number of very serious marine casualties involving fatal electrocution demonstrate that routine shipboard activities can present significant electrical risks when energized equipment is handled without adequate isolation, inspection, task-specific risk assessment, supervision, or appropriate safeguards. The Administration has reviewed several fatal electrocution incidents that occurred: Continue reading “Ensure the SMS adequately addresses electrical hazards”

Cat fines risk engine damage and operational delays

Recent bunker alerts have pointed to a growing presence of high-abrasive fuels containing cat fines in several regions, leading to further cat fines risk. The latest VPS Bunker Alerts confirm this upward trend, which is increasingly contributing to operational challenges and disputes within the shipping sector.

If not properly managed, cat fines can cause severe engine wear and, in extreme cases, lead to complete engine failure in a relatively short period of operation. Damage involving multiple cylinder liners and piston rings can be particularly costly and disruptive. Because vessels typically carry only one or two spare liners on board, extensive damage can quickly exceed onboard repair capacity. This often results in prolonged off-hire periods, as additional spare parts must be sourced and shipped in, with supply chain delays further extending repair timelines. Continue reading “Cat fines risk engine damage and operational delays”
