TMS Tankers opts for Coldharbour’s BWTS

Sep 08 2017


Ballast water treatment systems (BWTS) manufacturer Coldharbour Marine is to retrofit its patented inert gas type system GLD BWTS on TMS Tankers fleet.

The tanker owner, part of Athens-based TMS Group, currently operates 43 vessels.


The 2013-built Suezmax ’Bordeira’ will be the first to be fitted with Coldharbour’s BWTS early next year and will be used to carry out US Coast Guard (USCG) type approval tests, supervised by Lloyd’s Register. LR has Independent Laboratory Approval status with the USCG.

The classification society has already overseen IMO type approval for the Coldharbour system, validated by the UK’s Maritime and Coastguard Agency (MCA). The ‘Revised G8’ certification tests agreed by the IMO’s MEPC last year will be undertaken simultaneously.


“We are delighted to be working with TMS,” said Andrew Marshall, Coldharbour Marine CEO. “Our system was designed from the outset for large tankers and similar vessels – it is our primary target market. We understand from our customers that there is still much confusion regarding ballast water compliance timetables and how the practicalities of implementation will happen. Our ethos is to help our customers make the best decisions at the right time. Our mission is to safeguard the interests of shipowners in our market segment and to protect their profits from the costs associated with the delays and the unavoidable regrowth dangers that will lead to PSC fines and C/P disputes. Unlike some vendors, we are not in a rush.”


Evangelos Sfakiotakis, TMS Tankers’ technical manager, commented: “We have carried out a careful assessment of the available technologies for our large tankers and have satisfied ourselves with Coldharbour’s inert gas-based system. There are several reasons for this, but the two main ones are; firstly, that the Coldharbour technology featuring the combination of no filters plus in-voyage treatment process guarantees that our ballasting operations will never be disrupted, and secondly, that the treatment during voyage avoids the potential risk of regrowth during a long ballast voyage.

“This ensures that not only will our tankers be able to meet required discharge standards at all times, but also that we can be absolutely certain that the commercial availability of the vessel will never be adversely affected by BWTS issues,” he said.


Marshall explained that TMS Tankers had been clear that the technology it selected would need to be a long-term solution for existing ships that could serve without any risk or compromise to the way that its vessels are operated. “When we were developing our BWTS we prepared life-long ship financial timeline scenarios to understand how we could protect shipowners’ interests and how selection of a not-fit-for-purpose BWTS could negatively affect a ship’s profitability. Selection of the GLD BWT System by a company with TMS Tankers’ reputation for technical expertise vindicates our approach,” he said.


There is still much ‘discovery’ to be made by ship owners as they start to come to grips with the realities of day-to-day BWTS operation, Marshall added. Delays, breakdowns, crew training and the repercussions of Port State Control (PSC) sampling protocols are just some of the hidden costs that are set to bite.


“The consequences, both financial and reputational for shipowners of making an incorrect decision on treatment technology will haunt the industry for years to come. Owners must ensure that the systems they install are fit-for-purpose – and that does not simply mean having a Type Approval certificate, be that from IMO or the USCG,” Marshall concluded.
