The first MHI UEC33LSE engine

Mitsubishi Heavy Industries Marine Machinery & Engine Co (MHI-MME) has announced that the first example of its UEC33LSE is to be installed in a chemical tanker currently being built in China.

The UEC33LSE is based on MHI’s UEC35LSE, and the company says the two are the most advanced in its portfolio of low speed marine diesel engines. The engines have been designed for ships of under 30,000gt. Including small bulk carriers, chemical tankers and cement carriers. The UEC35LSE was developed in cooperation with Wärtsilä, and the first example, built by licensee Kobe Diesel, is now in service in the recently-delivered Tachibana-Maru cargo-passenger ship, built by MHI.

The smaller-bore UEC33LSE features a longer stroke and lower rotation speed than other engines of similar size, which MHI says has been shown in tests to improve propulsion efficiency. MHI claims that the engine offers the lowest fuel consumption in its class.

The first UEC33LSE was manufactured by licensee Akasaka Diesels and handed over in May to Kitanihon Shipbuilding in China Limited, and is being installed in a chemical tanker for Yamato Kisen. MHI adds that its Chinese licensee Zhejiang Yungpu Heavy Machinery Co has received several orders for UEC33LSE engines to be installed in container ships built at Taizhou Maple Leaf Shipbuilding.
