The 10 Step Guide to Selecting a Ballast Water Management System

Selecting the most suitable ballast water management system (BWMS) for a specific vessel is a critical, and often, underestimated task. With over 50 commercial systems available, operating on numerous combinations of different technologies and treatment processes, the suitability of any one system to a specific vessel cannot simply be presumed. The criterion for comparison of different systems for a specific vessel is not simply technical. Commercial considerations, operational requirements and through life and after sales support are all just as critical...

Open Loop Scrubbers – An Overview

With the IMO’s 2020 global sulphur cap deadline getting closer, owners and operators are faced with having to make a significant operational and commercial decision – whether to continue operating on low sulphur fuel, post 2020, or whether to finance the retrofitting of a scrubber system to the vessel. Depending on the type of scrubber selected, retrofitting the system to an existing vessel can be a complex and expensive process. Setting aside the significant capital cost of the technology itself, the engineering required to integrate the scrubber system...

Ballast Water Treatment & Vessel Performance – 4 Key Impact Points

Vessel performance can be impacted by a ballast water treatment system in many ways, some of which could have ongoing commercial and/or contractual implications. In a recent article on the impact of vessel ballast performance on Charter Parties, North P&I Club stressed the importance of ensuring charter party warranties are adjusted to reflect any change in vessel performance as a result of installing a ballast water treatment system:

Low Sulphur Fuels – A Sustainable Compliance Method?

With the IMO imposed global deadline, under MARPOL Annex VI, of 1st January 2020 for 0.5% sulphur content of fuels drawing nearer, the importance of determining the optimum commercial and technical compliance solution for any given vessel is never higher. With scrubbers costing often in excess of $5 million to retrofit, the low investment option of switching to low sulphur fuels is certainly attractive to many owners and operators...

Ballast Water Compliance Challenges Series – Passenger Vessels

The Cleanship Solutions compliance challenges series is a suite of ground breaking resources dedicated to the specific ballast water management compliance challenges faced by unique vessel types. This edition examines the specifics of passenger ferries. Despite a comparative decline in the past decade, as international air travel has become more affordable...

Ballast Water Compliance Challenges Series – Bulk Carriers

Accounting for roughly one third of the entire merchant shipping fleet, bulk carriers are by and large the most significant vessel “type” of them all. Their optimised design ensures energy efficient performance in the transportation of bulk cargoes that are critical to economies worldwide. However, despite their popularity , bulk carriers are still, after 13 years of legislation and development of compliance solutions, faced with...

Ballast Water Retrofits – 7 Steps to Selecting a Technically Suitable System

Selecting the most suitable ballast water management system for a specific vessel is a critical, and often, underestimated task. With over 50 commercial systems available, operating on numerous combinations of different technologies and treatment processes, the suitability of any one system to a specific vessel cannot simply be presumed.

Ballast Water Management Retrofits – Key CAPEX Considerations

Generally there are a number of critical considerations of any ballast water management system retrofit project, including; CAPEX, OPEX, Technical Suitability and corporate viability. Many owners and operators focus solely on the CAPEX, since this, ultimately, is the biggest driver in today's sensitive commercial market. However, there are elements of the CAPEX analysis that many owners and operators are unaware of...

Ballast Water Retrofit Installations – Where, When and How?

One of the most important aspects of planning a retrofit installation is the installation methodology - where, when and how? Owners and operators have to juggle the importance of completing the retrofit installation efficiently and, most importantly, correctly, with the commercial pressures of minimising vessel downtime. The suitability of different installation approaches are entirely vessel, owner and operator specific.

Entry into Force – Stepping Across the Line in the Sand

The 8th September 2017 has, for the past 12 months, represented a theoretically significant moment in the lifecycle of the IMO’s much debated and much eluded Ballast Water Management (BWM) Convention. From this day forward, owners and operators are legally obliged to comply with the requirements of the legislation, starting, of course, with D-1 compliance.
