Going Green With Ballast Water Treatment System

Ballast Water Treatment System (BWTS)

Ballast water discharge from vessels today is recognised as one of the greatest threats to the ecological and the economic well-being of our environment. From 2024, all ships will be required to have approved Ballast Water Management Treatment (BWTS) System with the requirement of installing an approved system with the Ballast Water Management Convention adopted by International Maritime Organisation.

Types of BWTS

In ensuring for the treated ballast water to meet the standards of IMO, utilising or combining of two or more technologies is typically used. Different type of ballast water treatment systems in the market include:

1. Physical Separation or Filtration Systems
2. UV Systems
3. Chemical Treatment
4. Deoxygenation
5. Heat Treatment
6. Electric Pulse and Pulse Plasma Treatments
7. Ultrasonic or Cavitation Treatment
8. Magnetic Field Treatment

Process of Installation

The project timeline for the installation is typically completed within 18 days with a lead-time of 14-21 days for pipe fabrication and treatment. Even with the complexity of installing the system into the already compact engine room; we were still able to complete the work smoothly through early engagement, detailed preparation and focused discussion with ship owners on the usage of 3D modelling during the prefabrication phase.

Maximising your condition-based maintenance (CBM)

By keeping your vessels in check, is important to optimize required maintenance job for your vessel through every downtime it is put off water. With an increased throughput at dock, ST Engineering ensures a thorough look-through in providing best suitable works done in a single time it is docked up. Hitting the mark of the IMO 2020 regulations, shipping companies and marine contractors seek solutions to outfit their vessels with cleaner exhaust gas and ballast water systems.This is imminent when most vessels, are by and large doing upgrades for BWTS and/or Scrubber systems done cohesively together.

Now getting ready for the convention

In preparation for the expected influx of demand from ship owners, ST Engineering has as early as 2018 to date been no stranger in the provisioning of installing various BWTS; used globally and adopted by IMO. In the enforcement of protecting our environment through the leveraging on our expertise in ship repairs, engineering capacity and retrofitting capability.

Our recent BWTS installations include repeat customers namely, Stolt Tankers,  and Bernhard Schulte Shipmanagement (S) P/L who amongst others had recently completed their installation of the UV/filtration BWTS in Singapore.

Mr. Spencer Zeigler, Director of Marketing and Sales at STE Halter Marine and Offshore said “We are proud to welcome the Ocean Blacklion, which represents the third Diamond Offshore drillship performing similar upgrades of BWTS, At the request of the customer, devising a solution for a mechanical tie-in for the BWTS to avoid disrupting the internal coating systems at our facility in the United States.”
