Maritime Decarbonization & Engineering Insights from a Chief Engineer at Sea
Practical engineering knowledge for modern Chief Engineers: operations, digitalization and decarbonization compliance.

Bunker tank soundings and fuel quantity calculation
A merchant ship’s design includes tanks for cargo and fuel, with a focus on maintaining stability through regular monitoring of fluid levels. Accurate tank soundings are crucial for bunkering operations to prevent financial losses due to malpractices. Manual and automated methods complement each other to ensure precise fuel measurements and optimal performance.

What is crankshaft deflection and why is important to measured it?
The crankshaft is crucial in marine engines, transmitting rotational motion from cylinders to propellers or generators. Its failure, while rare, is costly and can be caused by defects such as cracks, deformation, and bearing misalignment. Regular deflection measurements are essential for maintenance to ensure proper engine operation.

Vessel accommodation air conditioning plant explained…
Effective air-conditioning and ventilation systems on ships ensure passenger comfort and crew well-being. They must control temperature and humidity while preventing moisture accumulation to avoid health risks. The systems utilize air handling units (AHUs), refrigerants, and heat exchangers, requiring regular maintenance to operate efficiently and safely.

Meet the Engineer Behind the Insights
Hi, I’m Chief Engineer Daniel George Teleoaca—the face behind ChiefEngineerLog.com!
After more than 25 years as a Maritime Engineer on merchant ships, I know first-hand that life at sea is a mix of technical challenge, teamwork, and constant learning. I launched this project because I believe the maritime industry’s future depends on sharing real insights, encouraging innovation, and guiding each other through big changes—especially when it comes to decarbonization and new technology.
My core values? Honesty, practical problem-solving, and always having your crew’s back. I’m passionate about helping engineers, maritime students and shipowners cut through the jargon and find solutions that really work—not just on paper, but on the open sea.
Whether you’re here for industry updates, technical how-tos, or a glimpse into what it really means to run a ship in today’s evolving world, I’m glad we’ve crossed paths. My goal is simple: to be the resource I wish I’d had when I started, and to help you steer your own successful maritime journey.
Welcome aboard—and fair winds!
