More Methanol Cargoes, More Off-Spec Risk

Methanol is having a moment. DNV's Alternative Fuel Insight data shows the methanol-capable vessel fleet passed 120 in early 2026, with several hundred more vessels on order. Argus Media has forecast that alternative marine fuel demand will exceed 10 million tonnes in 2026, with methanol driving much of that growth. The Methanol Institute has also significantly revised its own demand projections upward as production and orderbooks have expanded. In this article, we’ll take a look at what this growth means – especially as off-spec cargoes incidents increase…

What Is Dynamic Positioning? An Introduction

Some ships don’t drop anchor. Instead, they use a network of thrusters, computers, and sensors to hold their exact position at sea – sometimes for weeks at a time, sometimes mere metres from an oil platform, a wind turbine, or another vessel. This is Dynamic Positioning (DP), and it underpins some of the most valuable operations in the maritime and offshore energy industries.

This article explains what DP is, why it carries commercial as well as technical risk, and why an independent assessment – beyond the standard class trial – is worth commissioning before problems find you.

A Guide to Bulk Vessel Sizes

Ask most people in shipping what a bulk carrier’s “size” actually tells you, and the answer can get vague fast – a DWT figure, a hold count, a canal restriction, rarely the same thing twice. It can be especially confusing for people who are new to the industry.

This guide maps the most common bulk carrier size classes, from mini-bulkers to the 400,000-DWT Valemax and explains what each means in practice.

ISO 8217 Compliance: Why a Pass Isn't a Verdict

A bunker delivery note shows full compliance with ISO 8217. A few weeks later, the purifiers are struggling and nobody can say why. Or consider the reverse: an engine problem develops, and a fuel that met every numerical limit gets blamed by default.
