SunRui Marine Environment Engineering Co. Ltd is a very reputable Maker and well known within the International Maritime Market, for the development of BalClor Ballast Water Management System (BWMS).
The ambition of SunRui is to succeed in acquiring similar recognition in Exhaust Gas Treatment Sector.
The IMO Regulation, regarding the Global Fuel Sulphur Limit of 0.5% - 0.1% in the Emission Control Areas (ECAs), is entering into force on 1st of January 2020. In order for vessels to comply with the aforementioned IMO Regulation, SunRui has recently launched its new cost effective and reliable Marine Product the SOxFree Exhaust Gas Cleaning System (ECGS).
It is certain that the SOxFree EGCS is released late, as a significant number of Owners have already proceeded with the selection of a Scrubber system for their fleet. The reason for this delay was that SunRui preferred to do an enhanced Research and Development so as to ensure the Top Quality of the Product, instead of rushing to produce a problematic and prone to failures Scrubber System.
In addition, SunRui decided to cooperate with a Chinese Maritime University operating a 3.5 MW 2-Stroke Marine Diesel Engine, produced an equivalent Full Scale Scrubber Model and arranged for it to be thoroughly Tested in both Open and Close Loop Modes respectively. The Test Results were very successful and all the parameters such as the Pressure Drop, the Drainage Water PH etc. were found within the acceptable limits of the various International Regulations.
SunRui SOxFree EGCS has already achieved Approval In Principal (AIP) from LR and relative Certification is also expected to be acquired shortly from DNV-GL and CCS. At this stage a U-Type Design is offered for the Scrubber Tower, as this configuration offers a better safety level by eliminating the possibility of wash water flooding the engine. At a later stage an I-Type Design will also be offered, as the Dry-Running with this configuration creates a high corrosive environment to the Scrubber Tower Material and SunRui R&D Department is investigating this issue.
The Scrubber System can be offered with Open Loop, Closed Loop and Hybrid configuration options. At the moment, the interest from the Owners is focused on either the Open Loop option or the Hybrid option. The Open Loop System is simple and its main components are the Scrubber Tower, the Water Pumps, the Gas Analyzer and the Water Analyzer.
The Hybrid System is more complex, but it has the advantage that it can operate in Open Loop mode inside the Areas where the discharge of the Wash Water is allowed and in Close Loop mode inside the Areas where the discharge of the Wash Water is prohibited - enabling the Owner to avoid at all the use of the expensive Low Sulphur Fuel Oil (LSFO) or Marine Gas Oil (MGO). The Hybrid System includes the components of the Open Loop System and some additional components such as the Heat Exchanger, the Alkali Unit and the Water Treatment Unit.
Being a Pioneer Maker, SunRui is always trying to introduce innovative solutions. Currently, it is common for the Scrubber Makers to offer various Steel Alloys regarding the Scrubber Tower Material. SunRui is also able to offer Super Duplex Stainless Steel Material for the Scrubber Tower as an option. What differentiates SunRui from the other Makers is that there is a second option for the Owners: a Scrubber Tower which will also include Titanium Clad Plate Material. The Titanium can add High Corrosion Resistance, which is vital for a Scrubber Tower.
Another important advantage of SOxFree EGCS is that it can be offered together with BalClor BWMS as a Combined Project. In this case, SunRui will provide to the Owner a Turn Key Solution: Supply of Equipment, 3D Scan Service at the same time, Detailed Design and Engineering Study, Project Management, Supervision, Commissioning and On-board Training for both systems. There are already reputable Greek Owners who assigned to SunRui a Combined Retrofit Project for their VLCC and Aframax Tankers.
The customs clearance cost, the transportation cost and the installation cost of a Scrubber System to the Retrofitting Shipyard are also very important factors for consideration by an Owner. If a Chinese Shipyard is selected for the installation and SunRui is appointed as the Supplier for the Project, then the relevant savings for the Owner will be huge, in comparison to having to ship a Scrubber System to China from another country.
There are also additional benefits for an Owner to proceed with SOxFree EGCS:
• Short Delivery Time.
• The Components of the System are from Reputable Sub-Contractors.
• Established Service Network (same with BalClor BWMS).
• Cooperation with experienced Designing Companies.
• Provision of Onboard Training.
• 20 Scrubber Models are available, covering the demand from 1MW to 80MW.
• The Open Loop System is Hybrid Ready and can be easily converted to Hybrid System in the future.
• SunRui has already vast experience with Newbuilding/Retrofit Projects and has been cooperating with many Newbuilding/Retrofitting Shipyards.
• Advanced and Flexible Scrubber Designing.
• High Sulphur Removal Rate (exceeding 98%)
• Various offered choices of materials for the Scrubber Tower.
Concluding, the fact that SunRui is a member and has the support of the powerful state-owned CSIC Group, the experience and know-how of SunRui to design Marine Products, as well as the worldwide success of BalClor BWMS, are solid reasons for an Owner to entrust the SOxFree EGCS and install it either for a Newbuilding Project or to an existing vessel (Retrofit Project).
Since September 2015, Marine Plus is the Exclusive Representative of SunRui for the Greek Market and will ensure that each inquiry for SOxFree EGCS will be handled with priority and will meet the full attention of SunRui.
