The Yacht Environmental Transparency Index (YETI) is an industry-developed tool designed to benchmark yachts against a target reference line

The Water Revolution Foundation has issued an open letter called ‘Yacht Environmental Transparency Index’ outlining four recommendations to help foster more sustainable practices in the superyacht sector. These recommendations – billed as ‘yachting resolutions’ for 2025 – are aimed at yacht owners and family offices.

The Water Revolution Foundation was started from within the superyacht industry to help the industry reduce its footprint. It is an independent Dutch legal entity called a ‘stichting’, which is “an institution aiming to achieve a certain goal”. The foundation’s recommendations are as follows: Continue reading “WRF issues Yacht Environmental Transparency Index”

The International Association of Classification Societies (IACS) published a new Unified Interpretation UI SC307 on hydrocarbon gas detection and bilge high level alarms in cargo pump-rooms. The UI is set to be implemented by IACS societies on ships contracted to be built on or after 1 January 2026.

The interpretation says:
1. Characteristics of the cargoes and their vapors (flammability, density, etc.) should be taken into consideration to determine the type and arrangement of detectors. Continue reading “IACS interpretation on hydrocarbon gas detection”

Several ships in Singapore and Rotterdam have recently reported issues after using cashew nutshell marine biofuel.

Reported operational problems included fuel sludging, injector failure, filter clogging, system deposits and corrosion of turbocharger nozzle rings. CTI-Maritec carried out extended gas chromatography mass spectrometry testing for very low sulphur fuel oil samples from the vessels. The results showed the fuel was blended with Cashew Nutshell Liquid (CNSL) from undeclared source materials or production processes.

CNSL, a non-FAME biofuel, is a naturally occurring byproduct of the cashew nut industry and acts as a low-cost alternative renewable fuel. Continue reading “Cashew nutshell marine biofuel warning sent out”

the DNV have expanded emissions regulations in Californian ports

To reduce emissions from oceangoing vessels while in port, DNV have expanded emissions regulations. The 2020 CARB At-Berth Regulation will require tanker and Ro-Ro vessels to use a CARB Approved Emission Control Strategy (CAECS) while at berth in California ports starting from 1 January 2025.
And classification society DNV has released details on the forthcoming next phase of the regulation.
The 2020 At-Berth Regulation requires all oceangoing vessel operators and terminal operators to report each visit made to any California marine terminal. However, only container, refrigerated cargo and cruise vessels have emissions control requirements. Continue reading “DNV on upcoming expanded emissions regulations in California”

From next year, the amended EU Monitoring, Reporting and Verification (MRV) regulations will be extended to cover general cargo vessels with a gross tonnage of 400 to 5000 and offshore vessels of 400 GT and above.
The St. Vincent and the Grenadines Maritime Authority has issued a circular explaining the key changes, including steps for operators introducing EU MRV for the first time.
Currently, the EU MRV regulations applies to ships of 5,000 GT and above, regardless of their flag, conducting commercial voyages to or from ports in the European Economic Area (EEA). EEA includes EU plus Norway and Iceland.
It requires the per-voyage and yearly monitoring of CO2 emissions to a central database and an annual public disclosure Continue reading “Steps in introducing EU MRV for the first time”

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”

New biosecurity requirements by New Zealand authorities

New Zealand’s Ministry for Primary Industries (MPI) is introducing the Biosecurity Pre-Arrival Report (PAR) for all commercial vessels calling in New Zealand starting 31 October 2024, replacing the current Master’s Declaration (MD) and Biofouling and Ballast Water Declaration (BBWD).

According to NorthStandard P&I Club, the PAR will not be mandatory for the first six months, during which MPI will still accept the MD and BBWD, but from 1 May 2025, it will become mandatory, and the old documentation will no longer be accepted. The PAR must be submitted at least 48 hours prior to arrival in New Zealand territorial waters. Continue reading “New biosecurity requirements by New Zealand authorities”

The Norwegian Maritime Authority (NMA) has issued an update for transporting biological liquid cargo following explosion after hot work was carried out near a vent from a tank containing fish silage.

Fish silage is fresh fish residue and formic acid. The acid conserves the residue and delays the process of decomposition. When organic material decomposes in environments where there is little air, hazardous gases may form. Continue reading “Hazards when transporting biological liquid cargo”
