EU-funded First LNG Retrofit of a TSHD

| The Netherlands, Delft

The retrofitting of the trailing suction hopper dredger (TSHD) Samuel de Champlain is being carried out as part of an EU co-funded Connecting Europe Facility (CEF) action — ‘Spanish/French Sustainable Atlantic Motorways of the seas Using as fuel for Engine LNG’ (abbrev. ‘S/F SamueLNG’) — which in turn is the first phase of the Global Project ‘Towards a Blue Atlantic Arch by 2025’.

The 8,500m3 TSHD vessel is owned by Dragages Ports (DP) (a member of the Central Dredging Association – CEDA), the project leader, and will be retrofitted from Marine Gas Oil to a dual-source fuel system.

The overall project aims to improve the sustainability of marine traffic through the use of marine Liquefied Natural Gas (LNG) as an environmentally-friendly, and cost-effective, alternative to conventional ship fuels for small vessels.

According to the ‘Third IMO Greenhouse Gas Study 2014’, maritime transport emits around 1000 million tonnes of CO2 annually and is responsible for about 2.5% of global greenhouse gas emissions. Shipping emissions are predicted to increase by between 50% and 250% by 2050 – depending on future economic and energy developments – and something clearly needs to be done. Such increases are not compatible with the internationally agreed goal of keeping the global temperature increase below 2°C, compared to pre-industrial levels. The current goals require worldwide emissions to be at least halved, from 1990 levels, by 2050.

Subsequently, the IMO’s Marine Environment Protection Committee (MEPC) has agreed that implementation of a 0.5% global sulphur cap on marine fuel will be brought forward to 2020, from the originally proposed date of 2025. The S/F SamueLNG Project will contribute to this by helping to achieve the objectives of two key EU Directives: Directive 2014/94/EU on the sustainability of the European maritime transport and Directive 2012/33/EU on reduction in the sulphur content of marine fuels.

In addition to the retrofitting of DP’s Samuel de Champlain, over the next three years, the S/F SamueLNG Project will also cover the following key activities:

  • LNG bunkering studies including: a risk assessment in the port of Nantes Saint-Nazaire, a mobile bunkering unit in the Port of Gijon, and a floating device in the Port of Vigo (in conjunction with each of the port’s partners)
  • Environmental Impact Assessment studies in the Ports of Rouen, Le Havre and Nantes Saint-Nazaire
  • The training of staff involved in LNG operations in the Ports of Nantes Saint-Nazaire and Rouen
  • Dissemination of the results to the maritime community

The SamueLNG Project is coordinated by DP and supported by a solid consortium of 12 partners, from along the Atlantic Arch, representing France, Spain and the Netherlands.

CEDA will co-lead on activities relating to the dissemination of project results to the maritime community. This work will be supported by a CEDA Environment Commission Task Group. Over the three years in which the S/F SamueLNG Project is scheduled to run, CEDA will work with project lead DP, and other key organisations in the Consortium in Spain and France, to disseminate the latest information and learnings to members.
