Vessel Performance & Data 1 course
Paid Foundation
The Road to Efficiency
A fleet's efficiency is decided by what it can see. Starting from the industry's most expensive blind spot, hull fouling, this course builds the road out: continuous monitoring, honest data pipelines, defensible quality, ISO 19030, and the culture that makes it stick.
Hydrodynamics & Ship Design 1 course
Paid Foundation
Ship Resistance Fundamentals
What actually slows a ship down in calm water: the five components of resistance, where each one comes from, and which of them you can influence from the bridge.
Regulations & Decarbonisation 5 courses
Free Foundation
Maritime Regulations, Explained
EU MRV, IMO DCS, CII, EU ETS and FuelEU Maritime: five regulations, one storyline: first they measured shipping's emissions, then they graded them, then they priced them, and now they are changing the fuel itself.
Free Foundation
The IMO Net-Zero Framework
What the IMO's approved, but not adopted, mid-term measure would require, and where it actually stands: a declining well-to-wake GHG fuel intensity path for ships of 5,000 GT and above, two target ladders year by year to 2035, two-tier pricing at USD 100 and USD 380 per tonne with a settlement rule that differs between the tiers, surplus units and their two-year life, rewards for zero and near-zero fuels, the 31 March and 30 September reporting dates, and the dated record of two failed adoption attempts, a reopened text and the rival proposals now sitting beside it.
Free Foundation
Alternative Fuels for Shipping
A fuel-by-fuel tour of every serious contender, LNG, LPG, methanol, ammonia, hydrogen, biofuels, e-fuels, batteries and nuclear, built on one comparison framework, so you can weigh energy density, safety, cost and availability the way an owner's technical team does.
Free Foundation
Energy-Saving Technologies
What rotor sails, air lubrication, energy-saving devices, waste-heat recovery and shore power actually do to a ship's energy bill, and how to read a vendor's savings claim before you sign for the retrofit.
Free Practitioner
Onboard Carbon Capture
What it takes to capture CO2 from a ship's own exhaust: the technologies, the energy penalty, the tanks, the missing shore infrastructure, and the regulatory question that decides whether any of it pays.
