With Exmar on board, ballast-free LNG carrier project enters Phase II

Signing ceremony for Ballast-Free LNGC Phase II JDP

APRIL 17, 2018 — LNG containment engineering company GTT, classification society Lloyd’s Register, and Chinese shipbuilder Dalian Shipbuilding Industry Corporation (DSIC) today launched the second phase of their “30,000 cu.m B-FREE LNG carrier” Joint Development Project (JDP).

A meeting was held today at Lloyd’s Register premises in Shanghai to commence Phase II of the project, and to welcome energy supply chain provider Exmar as a new partner to the JDP.

The first phase of the project performed by DSIC, GTT and Lloyd’s Register developed a new design of ballast-free, medium-sized LNG carrier, fully compliant with the new IMO Ballast Water Management Convention, and using membrane containment systems. It showed the potential for competitive advantages for shipowners, combining environmentally-friendly features with increased efficiency. It also indicated potentially lower construction and operational costs. The design received an Approval in Principle (AIP) from Lloyd’s Register in December 2017.

Phase II of the project aims to develop the design further, and to validate the initial results achieved during Phase I by applying more detailed analysis and verification, including model testing. The addition of Exmar brings a wealth of experience in operation of gas ships to the project team, which will help take the design from a concept to a viable, practical vessel meeting the requirements of end users.

“The ballast-free concept is a well-suited solution in the context of a shipping world with growing environmental requirements and concerns,” said Pierre Dincq, Managing Director of Shipping at Exmar. “By eliminating the need for ballast water, there is an absolute certainty that no invasive species will be transported on board of the vessel. Moreover, the ballast water treatment plant can be omitted, reducing the maintenance requirements and the energy consumption of the vessel which has a positive impact on the CO₂ footprint of the vessel. The combination of the long experience in their respective fields and a strong innovation culture of the several partners in the JDP will ensure this project will become a success. “

“After the encouraging results of the first phase, we are looking forward to delving into the details some more in the coming months. It’s a pleasure to be working with such experienced and capable partners on an innovative new design”, said Chris Hughes, General Manager Business Development of LR China.

Mr. Ma Yingbin, Deputy Technical Director of DSIC commented: “We have built experience on reduced ballast water oil tanker design such as VLCC, Suezmax and Aframax type vessels in the past and this experience will benefit to this ballast free medium size LNGC development. DSIC will focus on ship arrangement, performance calculation including hull line optimization by CFD and ship model test verification, propulsion selection and hull structure basic design. We are confident of ending up with a solid design and a competitive offer both in cost and performance” he added.

Lorenz Claes, naval architect in charge of the project at GTT, said : “We are excited to pursue the development of the promising ballast-free design and welcome Exmar, our long-time partner, in this project. Their involvement clearly demonstrates the interest of the industry in this new type of vessel, both environmentally-friendly and of high economic interest”. Adnan Ezzarhouni, General Manager of GTT China, who took part to the ceremony, added: “Our Company really appreciates working on such joint development projects, enabling the sharing of the knowledge of stakeholders and maintaining our innovation goals”.
