BWMS ONE-STOP SOLUTION

BWMS ONE-STOP SOLUTION
Detailed introduction

With the IMO International Convention for the Control and Management of Ships Ballast Water and Sediments ratified now, the reduction of sulfur emissions and increase of sewage discharge limits looming, shipowners around the world are faced reasonable modification for existing ships to meet regulatory requirements. Though there are very few companies that can provide professional solution for the shipowners.

Pollution caused by discharge of ship's ballast water has been confirmed as one of the four major pollution sources to the world oceans. UV disinfection has become one of the most mature, reliable, effective pure physical methods for ship's ballast water disinfection.
For the ship's ballast water, this specific treatment object, BSKY expert designs enhanced physical technology (EPT) including hydrocyclone separation filter + ultrasonic wave pre-treatment + UV reactor disinfection, uses powerful function to rapidly treat ballast water, so as to complete the ballast and discharge during loading and unloading, the treated ballast water discharged following treatment completely meets the requirement of International Maritime Organization (IMO) and United States Coast Guard (USCG).

Comparison of Hydrocyclone Technology with Traditional Filters

The biggest worry for ship owners — —Filter clogging problem

 


The size of sieve in the filter of all ballast water treatment device is 20-50μm, less than the diameter of hair, therefore, the clogging problem is a trouble to all users.

Filamentous, flocculent or trichosporon kinds marine microbe easily cling to a gap between protective mesh and filter screen, it causes terrible inconvenience during back flushing.

In case ship's draft line is deep, a lot of mud and sand will be sucked from sea chest, it would clog the filter.

This kind of a minute and fine filter brings big resistance to water flow, and it requires very high pressure to discharge water through the filter, which causes great pressure loss of ballast water pipe and great equipment pressure loss.

◆ Updating and development

BSKY owns a batch of scientific research teams with international professional level on ballast water treatment device, system is designed through computer fluid dynamics (CFD) calculation and several biological ID test through computer simulation (liquid flow pattern, light distribution, etc.), many biological tests and verifications meet USCG test standard and IMO new G8 standard. Professional design of efficient UV disinfection and management systems, including UV power and control system.

More advanced UV reactor design
Through simulating every drop of water in UV reactor (take grid with diameter of 50um pixel) to obtain consistent UV radiation energy, our new generation UV reactor has the RED (Reduction Equivalent Dose) energy effect 1.45 times higher than the former UV reactor on UV energy utilization. At the same time, this reactor has passed USCG and IMO NEW G8 type test and obtained satisfactory result.

USCG and IMO New G8 type Approval

BSKY has signed USCG type approval test contract with the independent laboratory KR designated by USCG, and conducted Land-based test on KOMERI platform in Korea.
The designated by USCG FDA/CMFDA analysis method is adopted and all test procedure meets the requirement of Environmental Technology Verification (ETV) protocol of United States Envionmental Protection Agency (EPA) and IMO new G8.

◆ Installation Reference

By the end of 2017,BSKYTM BWMS have been installed on vessels around the world, 142 vessels are Chinese owner,32 vessels are Japan, 30 vessels are Germany, 26 vessels are Singapore, and 24 vessels are other countries. Total reference is 254 vessels and 177 vessels are to new vessel, 77 vessels are to retrofit vessel.

◆ Project Service And Solution

Reverse engineering technology (3D Scanning) can improve the accuracy of locating the parts and pre-fitting of pipes during the installation of BWMS for ships in service,also it has the advantage of saving the time and the waste of the pipes.

Everglory has undertaken well over dozens of Ballast Water Management System Onboard Retrofitting projects and summarizes an effective solutions which have been unanimously approved by Owners and Classes through the assessment and testing. According to the actual situation of each ship,develop the most targeted and appropriate design and onboard retrofitting solution to achieve compliance ballast water treatment and sulphur emissions control legislation with minimal interruption time of operation avoiding unnecessary downtime.
