A new, peer-reviewed study conducted by University College London’s Department of Mechanical Engineering in collaboration with RAD, a UK-based electric marine propulsion company, examined underwater radiated noise across a range of operating speeds, comparing electric and conventional boats. Their aim? To discover if electric boats really are quieter.

The study, titled ‘A comparative study of underwater radiated noise from electric and conventional boats’, is published in the Journal of the Acoustical Society of America (JASA). It was conducted by UCL’s Department of Mechanical Engineering in collaboration with RAD, a UK-based electric marine propulsion company.

RuleAgent an AI-powered tool helps maritime professionals access DNV’s rules and standards faster and with greater clarity

DNV has launched RuleAgent, an AI-powered tool that helps maritime professionals access DNV’s rules and standards faster and with greater clarity. Designed to reduce the time customers spend navigating regulatory material, it enables users to ask natural‑language questions and receive targeted results. Fully connected to DNV’s rules and standards database, this new tool provides complete traceability to DNV’s official sources.

Maritime regulations are continuously evolving. Navigating the more than 30,000 pages of DNV’s rules across multiple documents, chapters, and editions can be complex and time-consuming. By presenting content in real time, RuleAgent enables users to identify the relevant rule paragraphs quickly, reducing the time spent searching across multiple documents.

The Maritime Technologies Forum (MTF) has published new safety guidelines to support the safe operation of wind-assisted ships, those using wind-assisted propulsion systems, as the shipping industry increasingly adopts technologies aimed at reducing fuel use and emissions.

The guidelines provide recommendations for developing and implementing safety management systems tailored to vessels equipped with wind-assisted propulsion systems (WAPS), including rotor sails, suction sails and wing sails.

In edition 2 of the “Lithium-ion Battery Fires: What We Know So Far”, the Maritime Professional Council of the UK (MPC) warns of the rising risks and dangers of lithium-ion battery fires to ships, boats and their crews.

The maritime industry faces increasing incidents and fires due to lithium-ion technology, particularly with the growing use of electric vehicles (EVs) and a myriad of devices powered by these batteries. Lithium-ion batteries have a high energy density, making them efficient but also prone to catastrophic failures if mishandled.

IACS 2025 Annual Review published

The IACS 2025 Annual Review explores the work of IACS and its classification society Members during 2025 in leading the development of technical requirements and guidance to support global shipping.

The report identifies many areas of progress, including IACS’s ongoing role in supporting industry decarbonisation objectives and the IMO’s efforts to balance its environmental ambitions with safety. Through it’s Safe Decarbonisation Panel, IACS is supporting progress in respect of a number of alternative fuels, whilst remaining neutral on any preferred option. This includes the development of Resolutions on the safe use of alternative fuels which underpin IMO regulations, or the classification rules of each IACS Member.

Transport Malta has released a simplified final report into a starting air explosion during berthing operations aboard CMA CGM Shanghai in Singapore.

What happened

CMA CGM Shanghai arrived just outside its designated discharge port of Singapore in the early hours of 15 March 2025, completing an 11-day voyage from Karachi, Pakistan.

The vessel was expected to remain outside port limits for approximately 50 minutes. During this time, the crew prepared the pilot ladder and completed arrangements for the pilot, who boarded the vessel at 0612 local time.

Tokyo MOU shares preliminary results of CIC on Ballast Water Management

Posted on by News Hound

The Tokyo MOU has released the preliminary results of a Concentrated Inspection Campaign (CIC) it held which focused on aspects of the Ballast Water Management Convention (BWM) 2004.

The campaign was carried out from 1 September 2025 to 30 November 2025, jointly with the Paris MoU.

Over the course of the CIC period, involving all types of ships, a total of 9,244 inspections were carried out. Of these inspections, 6,930 (74.96%) inspections were performed using the CIC questionnaire and a ship was subjected to only one CIC inspection during the campaign period. During the period, 184 ships where CIC was carried out were detained in total (2.66% detention rate). Of which, 30 detentions were the result of inspections with CIC questionnaires, which were detained as a direct result of the CIC concerning deficiencies, reflecting a CIC topic related detention rate of 0.43%.

IMPA warns of risks of deregulation in maritime pilotage

Posted on by News Hound

The International Maritime Pilots’ Association (IMPA) has sent out a warning of the consequences of deregulation and competition in maritime pilotage.

Maritime pilotage is a public, not commercial, service that exists for safety of navigation — protecting people, the environment and trade. IMPA said some jurisdictions are tempted by the idea that deregulation and competition deliver a better service at a lower cost. This is a mistake, and the evidence agrees.

An Able Seaman died instantly after steel plates fell and struck him while on board Shaman Wisdom, said a safety investigation report by the Republic of the Marshall Islands Maritime Administrator.

What happened

On 5 June 2024, at 0800, the Bosun on board Shaman Wisdom instructed the ASD1 and ASD2 to select a suitable steel plate in the Forecastle Store to construct a step for one of the deck stairs. Both the ASD1 and ASD2 were wearing the standard PPE to work on deck, including a safety helmet, coveralls, and safety shoes.

New ISO standard for in-water hull cleaning published

A new standard on in-water cleaning of vessel hulls has been launched.

Preventing and removing biofouling on hulls of ships limits the introduction and spread of invasive aquatic species (IAS). This in turn threatens coastal environments by disrupting ecological systems, which can also negatively affect fisheries, aquaculture and tourism. Biofouling is also estimated to increase a ship’s fuel consumption by on average 9 % – this added fuel consumption costs the shipping industry billions of USD. Therefore, improving biofouling management across the global shipping fleet will have considerable benefits, both from an environmental and economic standpoint.

A passenger died following a fall while 100 others were injured after cruise ship Spirit of Destiny hit heavy weather in its voyage, according to an accident investigation report by UK Marine Accident Investigation Branch (MAIB).

What happened

Shortly after 1230 on 4 November 2023, the passenger vessel Spirit of Discovery lost propulsion in heavy weather while crossing the Bay of Biscay. This led to the vessel moving violently while the crew restarted the vessel’s propulsion. The propulsion issues, storm force conditions and vessel motion continued until the vessel was able to resume its passage the following morning. Over 100 passengers were injured during this period. Eight of the seriously injured passengers were taken directly to hospital on arrival at Portsmouth, England. One of these passengers, Trevor Gilks, later died from his injuries.
