BWTS installation: Finding the best UAE Shipyard

How do you select a reputable shipyard to do your next Ballast Water Treatment System (BWTS) installation? 

Doing a BWTS Installation will be a critically important decision for shipping companies this year. You need high quality, fast installation, and a good price. 

But how do you find the best shipyard to install your Ballast Water Treatment System?

BWTS Installation Deadline – Background

The International Convention for the Control and Management of Ships’ Ballast Water and Sediments, 2004 (BWM Convention), entered into force globally on 8 September 2017. 

This BWM convention was implemented to deal with the spread of invasive aquatic species. This means that ships engaged in international traffic are required to manage their ballast water to avoid introducing alien species into other environments.


IMO Ballast Water Management Deadlines & Standards

There are two standards of implementation, D1 and D2. 

D1 Standard: From day 1 all ships must comply with the D1 standard which relates to exchanging ballast water in open seas. 

D2 Standard: D2 specifies the maximum amount of viable organisms that can be discharged, including specified indicator microbes that are harmful to human health. 

Compliance deadlines:

All new ships need to comply with D2 from day 1.

By 2024 all ships, including existing ships, will be required to meet the D2 standard.
