Green Ship/Energy Efficiency Service

0

Since the China Classification Society (CCS) promulgated the Rules for Green Ships in 2012, good application effects have been achieved. In early 2020, CCS updated the Rules for Green Ships (2012 Edition) and released the Rules for Green Eco-Ships (2020). The Rules for Green Eco-Ships (2020) have repositioned the green and environmental protection requirements of ships, which fully reflect the concept of ecology first and green development and are more in line with the needs of the market and the times. Based on the original requirements for energy efficiency, environmental protection and working environment, according to the development trend of green technology, a comprehensive index system for eco-ships has been established for the first time. With environmental protection as the core content, the Rules give the technical requirements and index requirements for six aspects covering the control of greenhouse gas (GHG) emissions, prevention of alien biological transfer, environmental friendliness, control of water pollution emissions, control of air pollution emissions and control of hazardous material use, which fully reflect the requirements of safety, environmental protection and sustainable development.For more details, please contact us:Tel: 0086-10-58112871 E-mail: ti@ccs.org.cn

Type Approval of Green Ships (EEDI)

0

The Energy Efficiency Design Index (EEDI) of a ship is an estimate of CO2 emissions per unit of traffic volume (freight volume) during the design stage of the ship. EEDI is a design index that considers the main factors and possible improvement methods of CO2 emissions generated by the ship inworking conditions, and encourages ship designers, shipyards, and equipment manufacturers to take measures to improve the energy efficiency of the ship and promote technological progress and innovation. It has nothing to do with the operation situation of the ship. The use of the energy efficiency design index is to consider increasing the traffic volume of the ship and taking various measures to reduce CO2 emissions during the design stage of the ship.China Classification Society (CCS) officially released the Rules for Green Ships on July 10, 2012, which are the world’s first rules for green ships for energy conservation, environmental protection and working environment. In 2020, CCS upgraded the original Rules, combined with the new connotation of green and ecological development in the new era, and formulated the Rules for Green Eco-Ships (2020) which incorporate new concepts of ecological development, promoting the upgrading of new green technical standards, and guiding sustainable, high-quality development of shipping.According to the requirements of the Rules for Green Ships and relevant guidelines, CCS provides the following services:●   Green ship type approval/evaluation services: CCS provides green ship type approval/evaluation services to assist domestic shipyards and designers to develop ship types in accordance with the requirements of the Rules for Green Ships, or to upgrade the existing design of domestic shipyards and designers to improve the competitiveness of the industrial community. ●   Green ship classification service: All ships that meet the requirements of the CCS rules for classification and have good environmental protection and energy efficiency performance are granted the green ship I/II/III class notation as a whole, or a separate class notation is granted to one of these items. This will help shipbuilders to obtain more orders, shipowners to meet the relevant requirements of maritime regulations and port states, and charterers to better understand the environmental protection performance of ships and will also guide the industry to develop new green and environmentally-friendly ship types and adopt efficient green new technologies. For more details, please contact us:Tel: 0086-10-58112160Fax: 0086-10-58112873 E-mail: ti@ccs.org.cn

Inspection of ship materials and equipment (marine products)

0

Ships are made of a variety of materials and equipment and during a ship survey, these items are collectively called products. As ships sail on water for a long time, these products must meet the requirements of safety and reliability under challenging conditions, including situations with high salinity and high humidity in a dynamic, and long-term operational environment. Therefore, the role of the marine product inspection is to verify the conformity, applicability and reliability of materials and equipment through the technical evaluation in accordance with the technical regulations and specifications issued by the competent authority and classification societies. The inspection service is provided for product manufacturing companies, such as steel mills, equipment manufacturers, etc. Marine product inspections include individual/batch inspections, design approvals, type approvals, works approval, approval of inspections and testing institutes and principle approvals, etc. Following the inspections regime, the “Marine Product Certificate” (or “Equivalent Certificate”), the “Approval Certificate” and other documents are issued, respectively. China Classification Society (CCS) launched its product inspection services more than 60 years ago. It has mature inspection modes, working procedures, and operational methods, and has formed a relatively complete inspection system. CCS has an experienced inspection team who participate in more than 20 national-level scientific research projects every year. They implement effective control over each link that affects product quality like product design, manufacturing, testing and quality management, thereby ensuring that product quality meets the requirements of relevant conventions, laws and regulations, codes and standards, and providing a prerequisite for guaranteeing ship quality and the safety of life at sea. CCS performs approvals and inspections for product manufacturers worldwide in more than 70 countries and regions in Asia, Americas, Europe and beyond. CCS has approved more than 7,000 manufacturers and it issues more than 300,000 product certificates for its clients every year. The products inspected cover various industries such as metallurgy, machinery, electronics, oil, chemical engineering, and shipbuilding. For more information on the “Product Inspection” regime of the China Classification Society, please refer to Chapter 3, Part 1 of the CCS Rules for Classification of Sea-going Steel Ships(Click here). For more information, please contact us:Tel: 0086-21-3810-3599E-mail: mp@ccs.org.cn More convenient services:EFor more information, please refer to Chapter 3, Part 1 of the CCS Rules for Classification of Sea-going Steel ShipsEFor product inspection services, please consult your local CCS office EFor FAQs about marine product inspections, please click to download the Product Inspections information in FAQs

Verification by Real Ship Sea Trial

0

CCS has performed the real ship sea trial for the optimal trim application together with China Shipping Group, whose 4250TEU ship in service was selected as the test ship. Its major parameters are as follows: During sea trial, this ship is bound for Tianjin Port from Nansha Port, Guangzhou, with the departure draft of 8.7m. The test is performed in the Yellow Sea area at north latitude 34°. To ensure the accuracy of test results, this trial is implemented subject to the international ship and maritime technical standard ISO15016:2002(E). The ship speed, main engine revolution, main engine shaft torque, main engine shaft power and other parameters are respectively measured under three different trim conditions, namely, trim by bow, flat floating and trim by stem. To eliminate the influences from wind wave, the ship takes an S-shaped fore-and-aft movement, and the error of readings is reduced by making average reading. According to the sea trial results, when the ballast water is increased by 1800t and the trim condition is changed to trim by bow of 0.8m, the required main engine power is reduced by 910KW with the speed unchanged, and the total fuel consumption is reduced by 14t with a reduction of fuel cost by 70,000RMB, which is equal to an average reduction by nearly 20,000RMB per day. The energy saving rate is 9.2%. Based on comprehensive consideration of the ship trim adjustment scope and the all year round operation mode, the adoption of the optimal trim has helped the ship to achieve 5-8% energy-saving potential for its operation during the whole year, with average fuel consumption being reduced by 3.2 ton/day and CO2 emission reduced by 9.96 ton/day. Taken effective operation of the year as 200 days, 640 tons of fuel can be saved effectively for the whole year, and fuel cost per ship/year can be reduced by 3.2m RMB on assumption that fuel costs 5000 RMB per ton. Serial ships and sister ships can achieve scale benefits. Long time use of OTA can effectively change the operation habit of crew, make advance planning to realize optimal trim, lower demand for main engine power, save fuel, reduce carbon emission and achieve long-term benefits.

Ship Energy Efficiency Data Collection Software

0

To meet the requirements of MARPOL Annex VI on the ship fuel consumption data collection and EU Regulation on the monitoring, reporting and verification of carbon dioxide emissions from maritime transport, CCS has developed a software of ship energy efficiency collecting and monitoring. The software collects energy efficiency-related data such as the arrival and departure port name, arrival and departure time, fuel consumption and bunkering quantity, distance travelled and cargo carried, could be used for the monitoring, conducting statistics and analysis of the energy efficiency-related basic data, generating emissions report based on different standards(IMO and EU). The software can be installed on a ship and used independently or be used cooperatively with the “CCS Ship Energy Efficiency Management System” or enterprise systems. The software can provide reliable data source for a third party inspection agency to perform data verification and provide convenient and diversified services for shipping company in regard to the statistics, monitoring and reporting management of ship energy efficiency-related data. CCS provides the free software to our clients, which is easy to install and use. The software development takes into account the current IT configuration of the enterprises, in order to decrease the cost of the installation, operation and maintenance. With Chinese and English versions, the software can meet the requirements of IMO and EU on the monitoring, reporting of ship energy efficiency data, minimize the relevant costs of shipping enterprises, and help them to collect and report energy efficiency data and verify the carbon emission.
