LNG

Sept 18 (LNGJ) - Hanwha Ocean of South Korea, formerly known as Daewoo Shipbuilding & Marine Engineering, and French classification society Bureau Veritas have started a joint development project (JDP) on the structural assessment of independent LNG fuel tanks for ultra-large ships.

   “The particularity of these independent tanks is that they are not rigidly connected to the hull structure but are instead held by an important number of dedicated supports, which must be designed with consideration of non-linear structural response during operations, including loss of contact and sliding,” said a statement.

Gaztransport and Technigaz (GTT), the French LNG storage technology company, received three approvals from European classification society DNV on its latest development projects in alternative fuels.

Gaztransport and Technigaz (GTT), the French designer of LNG storage tanks for ships and for onshore, has chosen the Gastech Conference in Milan to launch a new corporate image and logo to reflect its clean-fuel role and broadening activities in storage and smart shipping.

French liquefied natural gas storage technology firm Gaztranzport and Technigaz (GTT) reported a more than 20 percent drop in revenues in 2021 and net income was down over 32 percent as contracts for 27 newbuilds and a substantial order book failed to boost the bottom line because of timings.

Norwegian company Høglund Gas Solutions has signed a contract to provide a turnkey retrofit with LNG fuel capability for a Base Marine Norway-owned ship, the bulk and general carrier “Hannah Kristina”, which has US oil services company Halliburton as the end-charterer.

“The project aims to improve the vessel’s environmental footprint by converting the marine diesel oil-fuelled vessel into dual-fuel by supplying an LNG Fuel Gas Supply System (FGSS) alongside an upgrade with shore power connection,” said Høglund.

The project, led by Høglund, will require extensive collaboration between numerous stakeholders, including naval architects, engineering teams, a retrofit shipyard, various suppliers, the class society flag state and the vessel owners and operators.

“Høglund will therefore collaborate with long-time partners HB Hunte Engineering GmbH and Fiskerstrand Verft AS for the naval architecture and shipyard elements of the project, respectively. The entire project will be classed by DNV,” explained the Norwegian company.

The scope under the contract consists of a 250 cubic metres capacity FGSS with a dedicated Gas Control and Safety System to serve the already installed dual-fuel system with natural gas.

“In order to implement the appropriate safety measures following the requirements of the IGF-Code and improve the safety credentials of the ‘Hannah Kristina’, Høglund will be combining its extensive knowledge in gas, power and automation solutions with HB Hunte’s outstanding expertise in naval engineering to perform further modifications on the vessel,” the company explained.

“These will include the adjustment of the mooring arrangement in the LNG tank area and an upgrade to the ventilation system, among other conversions,” added Høglund.
The delivery of the retrofitted vessel is expected to take place in March 2022.

“The goal of this project is to upgrade a 20-year-old vessel with modern environmental credentials. With the use of LNG and battery power, the vessel will significantly reduce its carbon-dioxide and nitrogen oxides (NOx) emissions both while at sea and during harbour stays,” said Høglund.

Høglund said it would ensure that the complex stakeholder management aspect of the retrofit works will be run effectively and that this will result in a well-executed project.

“The technological and environmental transformation of shipping over the coming years is one of the biggest challenges facing our industry,” said Philipp Ulrich, Senior Project Manager at Høglund.

“To achieve this transformation in a commercially viable and minimally disruptive way, meaningful and well-coordinated collaborations are essential,” he added.

Jean-Marc Lopez, Vice President of Halliburton in Norway, explained the reasoning for the move.

“By utilizing ‘Hannah Kristina’, Halliburton has moved huge amounts of goods from road to sea, reducing the emission of CO2 and NOx,” he said.

“With the conversion of ‘Hannah Kristina’ from diesel to LNG and shore power, we take the reduction of CO2 and NOx a step further, in line with our strategy to continue to reduce the environmental footprint of our activities,” declared Lopez.

Jan 15 (LNGJ) - French LNG storage tank technology company GTT has obtained approval in principle from France-based classification society Bureau Veritas for GTT’s No. 96 membrane containment system for LNG fuel tank applications for Ultra Large Container Vessels (ULCVs) . “GTT and BV reviewed the compatibility and safe integration of the No. 96 technology as an LNG fuel tank in a container vessel hull,” said GTT.

   Over the course of the study, a liquid motion assessment of the tank configuration was performed. “We are pleased to receive this new Approval in Principle which allows GTT to offer increasingly competitive solutions that meet the requirements of the LNG market as a marine fuel. This will enable all our licensees to offer membrane solutions to this market,” said Philippe Berterottière, Chairman and Chief Executive of GTT.

The shipbuilding unit of Japan’s Mitsubishi Heavy Industries has been granted approval for a liquefied natural gas fuel gas supply system (FGSS) for marine four-stroke, dual-fuel engines.
