Shipowners Eager to Find Fuel Saving Opportunities

With slow steaming becoming standard in the industry, owners see a growing need to retrofit ships to operate efficiently at low speeds, MAN Diesel & Turbo (MAN Diesel)'s Head of Retrofit & Upgrade Christian Ludwig told industry news site ShippingWatch.

Ludwig said MAN Diesel has been surprised how much interest shipowners have shown in the "de-rating study" the company offers, which considers operational aspects of ships and offers recommendations for improving fuel efficiency.

The company has received 27 orders for the service since mid-January involving ships in a range of size without making any major promotion effort, Ludwig said.

"Not even in our wildest dreams did we imagine that there would be so much interest for this," Ludwig said.

"These studies are the first step, and after that, to a certain extent the plan is to secure some orders for these optimizations."

Shipowners can achieve savings of 10 to 15 percent by reoptimizing engines for lower speed and changing propellers, Ludwig said.

"After the financial crisis slow steaming has become the norm, and the ships, the propellers and the engines are nowhere close to optimized for this," he said.

The studies cost €10,000 ($13,200) and take about six to eight weeks to complete.

Maersk Line said this spring that it is working with MAN Diesel on a research project designed to retrofit containerships to reduce energy consumption by up to 20 percent.
