New four-stroke engines comply with strict Chinese emissions regulations

In a milestone order for MAN Energy Solutions, CMP, its Chinese licensee, will supply a series of new, small-bore, four-stroke engines for the Chinese inland and coastal market that comply with new local emissions regulations.

The orders are for MAN 21/31, 27/38 and 23/30H model four-stroke engines that comply with China’s emissions protocols for the segment with its GB15097 regulation – commonly known as C1 and C2.

MAN Energy Solutions head of small-bore, four-stroke engineering Finn Fjeldhøj said “With the introduction of C1 and C2, we identified – in close co-operation with our Chinese licensees – the business potential in the Chinese inland market, prepared a business case, and initiated the appropriate design-and-performance test measures to make our engines compliant.”

Mr Fjeldhøj said, “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.” In order to incorporate C1- and C2-compliant engines into its engine programme, MAN Energy Solutions needed to have “strong engagement in developing performance and deterioration tests for the required certification,” he added.

CMP recently won the order to provide a 6S35ME-B9.5 Tier ll main engine, three 6L27/38 gensets and one 5L21/31 genset for a 15,000-dwt shuttle tanker currently under construction by Qidong COSCO Shipping Engineering Co for Shanghai Beihai Shipping Co. Expected to be delivered in October 2020, the genset fulfils Tier II and C1 requirements.

The project advances CMP’s strategy of creating a C1 orderbook and increasing its share of the Chinese domestic ship market. It also marks the first time CMP has won a two-stroke ME order within the COSCO Shipping group.

CMP has also won the order from Yang Zi Jiang Shipyard to supply engines for two 52,000-dwt bulk carriers, each featuring three 5L23/30H C1-compliant gensets that will be delivered in May 2021.

CMP further reports it is working on several bulk and roro 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 emissions requirements, even surpassing IMO regulations. The China GB15097 regulation – commonly known as C1 and C2 – includes limits for particulate matter and closely resembles limits set by US Environmental Protection Agency.

As of 1 August 2020, the China Maritime Safety Administration began enforcing ’The Statutory Technical Rules for The Inspection of Domestic Seaway Ships.’ GB15097 requires 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 roros and government vessels.
