1.Weihai Puyi Marine Environmental Technology Co., Ltd is located in Qingshan Road , Huancui Science and Technology Industrial Park , Weihai City, Shandong Province, China.covers an area of 570 Mu, total construction scale is 200,000 m2.

PUYI is the first ship’s desulfurization equipment manufacturer in Asia and there are mainly three productions: ship’s desulfurization equipment, energy saving and emission reduction equipment products of heavy fuel oil and equipment products of the ground-based facility desulfurization equipment. The exhaust gas cleaning effect meet the International Maritime Conventions’ highest standard of 0.1% sulfur oxides emission and has gained the certificate of CCS,  the ground-based facility desulfurization technology is an expansion from the marine desulfurization technology, which can control the emission concentration of sulfur dioxide from burning coal or fuel lower than 10 mg/m3, achieve the world class.

In 2006, PUYI start to research the marine exhaust gas cleaning technology. A test exhaust gas cleaning equipment was installed on COSCO BINGHE container ship , got the support of high-tech marine research project which approved by Industry and Information Technology Ministry of People’s Republic of China in 2012 and has passed the technical evaluation of Ministry of Transport. Another exhaust gas cleaning equipment was installed on COSCO LINGYUNHE container ship for pilotscale experiment, exhaust gas and water emission perfectly met the International Maritime Conventions’ standard and has gained the certificate of CCS, also won the certificate of LR and BV successively in May, 2016.

Our marine exhaust gas cleaning technology was awardedas key construction project in Shandong province and named the third group of Shandong province science and technology promotion projects.The implementation of the project, can enhance the performance ability of ship pollution prevention convention in our country, make  PUYI independent innovation capacity to a new level, replace imported ship’s desulfurization equipment, participate in international ship pollution prevention industry competition, promote the company enterprise sustainable healthy development.

2. Project Background

 The International Marinetime Convention said that there are four Emission Control Areas(ECAs) in the world:

   （1）The Baltic Sea Emission Control Area: the Baltic Sea proper with the Gulf of Bothnia and the Gulf of Finland and the entrance to the Baltic Sea bounded by the parallel of the Skaw in the Skagerrak at 57°44.8′ N.

   （2）The Black Sea Emission Control Area: the Black Sea proper with the boundary between the Mediterranean and the Black Sea constituted by the parallel 41° N.

   （3）The North America Emission Control Area: including the Pacific waters of the United States and Canada, the Atlantic waters of the United States, Canada and France(Saint Pierre and Miquelon), the Gulf of Mexico waters of the United States, the Hawaiian islands waters of Hawaiian, Maui, Oahu, Molokai, Niihau, Kauai, Lanai and Kaho‘olawe.

   （4）The Caribbean Sea Emission Control Area: The Atlantic and Caribbean waters of the Puerto Rico and the United States Virgin Islands.

    According to the International Marinetime Convention, the sulfur emission control standard should enter force in the English Channel, the Baltic Sea, the Caribbean Sea and North America on 1^st, January, 2015.

    All the vessels which are sailing in these ECAs, the sulfur contents shall not exceed 0.1%. The global 0.5% sulfur cap for marine fuel will enter force on 1^st, January, 2020. After 1^st, January, 2025, the sulfur cap may be reduced by 20%.

 Japan, South Korea, Hong Kong, China and Taiwan, China are applying to establish the emissions control area, the Hong Kong, China has been allowed to execute the convention on 1^st, July.

3. The Ship’s Sulfur Emission Control in Coastal Waters of China Has 

Been Introduced

On 2^nd December 2015, the Ministry of Transport has introduced The Ship’s Sulfur Emission Control Policy in Pearl River Delta, Yangtze River Delta and Circum-Bohai-Sea.( hereinafter referred to as Policy)

 According to the Policy, after 1^st January 2016, the vessels should strictly execute the current international and Chinese conventions relevant to the emission control of SOx, PM and NOx, the ports which are located in the ECA and have enough capacity can implement using low-sulfur fuel which sulfur content is under 0.5% and other measures which are higher than the current sulfur emission control requirement.

 After 1^st January 2017, the vessels which are berthing in the core ports (from 1 hour after reach the port to 1 hour before departure) of the ECA should use the low-sulfur fuel which sulfur content is under 0.5%.

 After 1^st January 2018, the vessels which are berthing in the ports of the ECA should use the low-sulfur fuel which sulfur content is under 0.5%.

 After 1^st January 2019, the vessels which are sailing in the ECA should use the low-sulfur fuel which sulfur content is under 0.5%.

 Before 31^st December 2019, the implementation effect of these measures will be accessed and determine if below measures should be taken:

The vessels which are berthing in the ports of the ECA should use the low-sulfur fuel which sulfur content is under 0.1%;

Increasing the numbers and area of ECA;

Other farther measures.

 The Ministry of Transport said that the Policy applies to all vessels which are sailing, berthing and operation in ECA, except military vessels, sport vessels and fishing vessels. The vessels may use shore power, change the clean energy source, install the exhaust gas treatment equipment and other alternative measures to achieve the same desulfurization effect.

  The scope of ECA:

Pearl River Delta ECA

The core ports which are included in this ECA are port of Shenzhen, Guangzhou and Zhuhai.

Yangtze River Delta ECA

The core ports which are included in this ECA are port of Shanghai, Ningbo-Zhoushan and Nantong.

Circum-Bohai-Sea ECA

The core ports which are included in this ECA are port of Tianjin, Qinhuangdao, Tangshan and Huanghua.

IMO sets global sulphur cap for 2020

27 Oct 2016

Clarity for ship owners, oil companies and technology providers as 2020 global sulphur cap confirmed

  The global 0.5% sulphur cap for marine fuel will enter force on 1 January 2020, the International Maritime Organisation’s Marine Environment Protection Committee has agreed.

    The decision on the cap, required under regulation 14 of MARPOL Annex VI, is in line with an official assessment on fuel availability – conducted by a CE Delft-led consortium – and provides much needed clarity to ship owners. The industry now has just over three years to decide on their compliance measures – either low-sulphur fuel, the installation of exhaust gas cleaning systems (scrubbers) or the use of alternative fuels (including LNG).

  The MEPC also agreed to ask its Pollution Prevention and Response (PPR) subcommittee to consider implementation of the global cap - including enforcement and operational concerns.

    As reported, the study by CE Delft concluded that there could be severe market impacts and logistical challenges with implementing a cap overnight.

  The official study also pointed to some regional shortages, but noted that these could be compensated for by oversupply from the Middle East, as well as excess production from other regions. In the base case, CE Delft sees demand for 233 million tonnes of marine fuel with sulphur of between 0.1% to 0.5% in 2020. This would primarily be blends of residuals, hydrotreated residuals, heavy fractions from hydrocrackers and lighter hydrotreated fractions - with a very wide range of viscosities.

  Scrubbers are projected to be installed on 3,800 ships, collectively consuming 14-38 million tonnes of heavy fuel oil in 2020.
