MAN Energy Solutions reports that its Chinese licensee, CMP, has won a series of orders in the Chinese inland and coastal market for small-bore, four-stroke engines that meet new and impending emissions protocols under China’s GB15097 regulation. Commonly known as C1 and C2, they set particulate matter emissions limits closely resembling those set by the U.S. EPA.

The orders are for MAN 21/31, 27/38 and 23/30H engine types. According to Finn Fjeldhøj, Head of Small-Bore, Four-Stroke Engineering, MAN Energy Solutions, “these are the first C1-compliant orders of their type and represent an important milestone for MAN Energy Solutions within the Chinese river-and-coastal segment.”

He congratulated licensee CMP for the work it had carried out in incorporating C1- and C2-compliant engines into its engine program and for its strong engagement in developing performance and deterioration tests for the required certification.

CMP recently won an order to provide one 6S35ME-B9.5 Tier ll main engine and three 6L27/38 and one 5L21/31 gensets for a 15,000 dwt shuttle tanker currently under construction by Qidong COSCO Shipping Engineering Co., Ltd for Shanghai Beihai Shipping Co., Ltd. The GenSets meet both Tier II and C1 requirements and engine delivery is scheduled for the end of October 2020.

The project is in line with CMP’s strategy of creating a C1 order book and increasing its share of the Chinese domestic ship market. The project also marks the first occasion that CMP has won a two-stroke ME order within the COSCO Shipping group.

CMP has also won an order from Yang Zi Jiang Shipyard to supply the engines for two 52,000 dwt bulk carriers, each featuring three 5L23/30H C1-compliant gensets.

CMP further reports that is also working on several, different bulk and RO/RO C1-compliant projects, mostly with MAN 23/30 applications.


Formerly, most diesel engines in this marine segment were locally produced by domestic brands. However, in recent years, the Chinese authorities have tightened emission requirements, even surpassing IMO regulations. The China GB15097 regulation—commonly known as C1 and C2—includes limits for particulate matter (PM) and resemble EPA U.S. limits closely.

The Statutory Technical Rules for the Inspection of Domestic Seaway Ships will be formally enforced by the China Maritime Safety Administration from August 1. GB15097 will require the exhaust emissions of all domestic, seaway, medium-speed, diesel engines to follow Chinese C1/C2 emission rules. The new legislation will primarily apply to domestic bulk carriers, feeder containers, oil tankers, passenger RO/ROs and government vessels—a sizable market.
