Ballast water management

LITEHAUZ has a strong knowledge of technical, biological and policy-making issues with regards to ballast water and assists policy-makers shipowners and developers with regards to implementing or complying with the requirements of the Ballast Water Management Convention. LITEHAUZ is your one-stop-service point to meet your needs in critical decisions points within all aspects of ballast water management regulation.
Policy makers
How could the requirements of the convention be implemented and enforced, what are the costs and implications and what should guidelines include? Litehauz has participated in these processes on both national and regional level with Danish authorities and the HELCOM/OSPAR joint working group on exemptions. Litehauz has provided impact- and scope studies as well as a number of proposals for the regional guidelines. Most recently we have coined the Same Risk Area concept.
Ship owners
For ship owners it is essential to be confident when making the choice of compliance approach, as the economical consequences of non-compliance or operational expenditures can be high. The key to meet this fundamental need and make informed decisions is to have your fleet and vessels operations analysed to identify the most cost-beneficial and environmentally sound ballast water compliance approach. The fleet analysis is a low cost, high value service to giving your confidence in your decision process.
Whether you choose to install an IMO/USCG approved treatment system or go for administrative solutions in form of exemptions, LITEHAUZ is your competent partner when the choice is to be implemented. We can guide you through the whole process taking into consideration costs and environmental fit of a system.
The uncertainty of whether an installed ballast water treatment system works or not is the source to many headaches for many shipowners. LITEHAUZ and MEDICO ApS have joint forces and are leading the development of the first inline on-time ballast water monitor that allows for early warning of insufficient treatment and potential non-compliance.

Private sector – BWM system developers
Obtaining a Basic-, Final- or Type Approval for Maritime your ballast water management system is a cumbersome and expensive process. LITEHAUZ provides unique knowledge of the quality requirements of the application dossiers from earlier work as appointed expert to the G9 assessment committee (GESAMP) and work with +10 system developers. We also collaborate with leading stakeholders in the US regarding the AMS approvals and US Type Approval processes.

Assessment of the risk of invasive species from ballast water discharge in the North Sea and Baltic Sea and associated costs of exemptions.

The 1st International workshop on BWMC exemptions – The Same Risk Area was organised by LITEHAUZ and hosted in the offices of Danish Shipping. 30 participants from eight countries descended to Copenhagen on 7th and 8th of May, 2018. A well balanced mix of first movers in administrations, shipowner, research and consultancy communities met to share experiences in designing studies for the Same Risk Area exemption approach.

The Ballast Water Convention entered into force on September 8th 2017 and as a result all ships must comply with the D-2 standard when its fully implemented in 2024. Initiated by Danish Shipping Litehauz developed a guide funded by the Danish Maritime Fund to make the transition easier for all the involved parties by emphasise the key points in the convention. The guide “The Little Blue Book on Ballast Water” can be found on the Danish Shipping webpage by following this link.
