Hyundai Heavy Industries Co., Ltd. (HHI) says it has completed a type approval test of two ultra long stroke marine engines that are capable of reducing fuel consumption by 7 percent, under license with MAN Diesel & Turbo (MAN Diesel).

The G-type marine engines, 7G80ME-C9.2 and 6G80ME-C9.2, were tested at 42,350 bhp and 36,300 bhp respectively, with the test attended by supervisors from 11 classification societies.

One G-type engine was installed on an Almi Tanker (Almi) very large crude carrier (VLCC) and another is scheduled for installation on a Thenamaris Ship Management (Thenamaris) containership.

The engines will save $2.9 million per year for Almi and $1.3 million per year for Thenamaris compared with a standard engine with the same output, according to HHI's calculations.

Shipowners are increasingly eager to use fuel-saving technology such as the ultra long stroke engines for VLCCs, a MAN Diesel executive said recently, discussing Almi's decision to use the engine.

Teekay and AET have also recently ordered vessels using ultra long stroke engine technology to save fuel.
