Nigeria LNG Limited harnesses Nigeria's vast natural gas resources and produces LNG for export. Owned by the Nigerian National Petroleum Corporation, Shell, Total and Eni, it owns and charters over twenty LNG carriers through its subsidiaries Bonny Gas Transport (BGT) Limited and NLNG Ship Management Limited (NSML).
These export over twenty million tonnes per annum of LNG. Four are Moss-type, the rest have membrane containment systems.

Temilola Okesanjo, General Manager for NLNG Shipping Services, says his job is to ensure effective, efficient, smart running and the development of NLNG and BGT Shipping and Marine Activities. “I have to deliver on its shipping objectives and commitments over the short and long term including ensuring fulfilment of the requirements of the NLNG and BGT boards of directors and shareholders,” he explains. “I oversee and coordinate the activities of the Shipping Division and BGT ensuring that NLNG shipping and marine assets provide maximum value to NLNG and BGT shareholders respectively.”

“There is a strong safety culture within the company and I focus on that,” explains Temilola. “We used different ship managers, some in house and some external and I oversee implementation of vessel management agreements and the activities of the appointed Fleet Managers and provide assurance over the management of BGT and NLNG Shipping activities.”

In recent years Bonny Gas Transport has embarked on major life extension schemes for part of its fleet, working with Bureau Veritas to assess the needs of the vessels to continue to operate safely.

“NLNG and BGT have had a long term relationship with Bureau Veritas dating back to 1990’s when LNG Lagos and LNG Port Harcourt were acquired by BGT,” says Temilola. “Since then, BV has continuously demonstrated a wealth of shipping and marine experience and has steadfastly provided NLNG and BGT with all the necessary and required shipping and marine support in areas of ship classification, ship construction, ship survey and life extension of our assets. They help to keep us safe.”

Bureau Veritas will class around fifty per cent of the order book for new small-scale LNG carriers, many of which are being developed to meet the needs of a new bunker chain for LNG as fuel for ships.
This leadership is built on experience with helping Rotterdam-based Anthony Veder build a fleet of highly-flexible small gas carriers under BV class and although these are built for LNG/LPG/LEG transport and distribution they also have the capacity to act as LNG bunker tankers. It is likely that the BV-class 6,500 cu m Coral Anthelia will be the first vessel actually deployed as an LNG bunker tanker, working on charter to Norway’s Skangass to deliver LNG as fuel in the Northern North Sea/Baltic areas from 2016.
The first purpose-built LNG bunker tanker is being built to BV class at Hanjin, Korea, for a joint-venture between Japan’s Mitsubishi and NYK Line, Belgian gas logistics company Fluxys and French energy major Engie. Norway’s Skangass has an established client base of LNG-fuelled passenger ferries and tankers. It plans to operate a 100 m LOA bunker vessel which will carry 5,800 cu m of LNG at 4.5 bar in two bi-lobe tanks. The vessel will be built to BV class at Royal Bodewes in the Netherlands for Sirius Veder BV.

EU supports LNG fuel drive

Bureau Veritas has joined two new EU-funded projects in Spain intended to speed the uptake of LNG as fuel. The CORE LNGas hive Joint Development Project involves forty-two entities in Spain and Portugal, including public bodies, port authorities, shipowners, gas companies and equipment manufacturers. The objective is the sustainable development of an LNG fuel network in these countries.
One of the pilot studies included in the Gainn4Mos project is the conversion of a bunker barge into a dual-purpose bunkering tanker able to deliver bunkers of liquid fuels and LNG to gas fuel ships in Spain. The pilot study is led by Fundacion Valenciaport, along with the Spanish Merchant Marine, Boluda Corporacion Maritima, CIMNE, Seaplace and Bureau Veritas.

Clean cold gas carriers

The 162,000 cu m LNG carrier Clean Vision has been built to BV class at S. Korea’s HHI yard and delivered to Dynagas in January 2016. Sister to the Clean Planet, already in service, the vessel has a Mark III Flex containment system, TFDE propulsion, and is assigned Ice Class 1A and winterization which enables operation in extreme low temperatures.

hybrid ferry launched

seaspan lng hybrid ferry launched

On March 5, 2016, the first LNG hybrid ferry for SEASPAN Ferries was launched at SEDEF shipyard in Turkey. The second vessel is under construction on the slipway.
The two vessels will be the first Dual Fuel hybrid ferries to operate in Vancouver, British Columbia. Bureau Veritas is very proud to have been selected as a major partner for this breakthrough project. The hybrid propulsion systems reduce emissions and improve operational efficiency. This new class of vessel demonstrates that a new era of responsible and sustainable transport has become a reality.



While major advances have been made in fuel efficiency of LNG carriers there is still much that can be done to reduce consumption. BG Brasil (now, a Royal Dutch Shell plc. subsidiary company) teamed up with Bureau Veritas and its subsidiary HydrOcean, containment manufacturer GTT and UFRJ (Federal University of Rio de Janeiro) to seek ways to reduce even further the fuel consumption of the Lake Charles 174,000 cu m LNG carrier class. The project took a fresh look at every aspect of an LNG carrier design, including hull form optimisation in calm water and in waves, tank arrangement, machinery architecture, propeller and rudder design.

The optimisation process was performed using state-of-the-art CFD (Computational Fluid Dynamics) tools. More than 200 hull forms were evaluated leading to more than 2000 CFD simulations using multi-processor parallel computing.

The project led to a new bow design which provides impressive performance in both calm water and waves. A new hybrid geometry for the No. 1 cargo tank was suggested, which combines two existing technologies, cylindrical and trapezoidal tanks. The possibility of installing a 2,500 cu m heel tank for self-cool-down and gas-up operations as well as for operation within SECA/ NECA zones was investigated. The heel tank would be a GTT membrane tank with MARVS of 2barg that could operate at any filling level.

Jose Ferrari, Technology Manager, BG Group, says, “Collaboration between team members was a key element in the success of the project. The ability and skills in advanced hydrodynamics and integrated ship design were paramount to the successful achievement of project objectives and the delivery of business value.”

Bureau Veritas’ SEECAT (Ship Energy Efficiency Calculation and Analysis Tool) was used for the assessment of energy efficiency. Overall, the optimised vessel presented a performance around 11 per cent better than an existing ship used for comparison purposes. 

Although the optimised hull is not directly comparable to the current 174,000 cu m LNG ship designs currently available in the Far East yards, the proposed hull form is very competitive. Based on the feedback obtained from key shipyards, additional work is required to refine further the design and will focus on the optimisation of ship particulars and ship´s aft body.

Moss-type FSU conversion

Bureau Veritas recently worked with Bumi Armada Berhad on the conversion of a 5-sphere 125,000 cu m MOSS-type LNG carrier to a Floating Storage Unit which will provide gas to a power utility company in Malta.

The BV-classed conversion is currently ongoing in a Singapore shipyard and is expected to be completed in the 3rd quarter of 2016.

Bureau Veritas’ consulting arm, Tecnitas, provided an initial assessment, survey and renewal evaluation programme using BV’s HLC software prior to the acquisition. Following acquisition by the client, a thorough structural assessment was performed including a complete ship model Finite Element Analysis to assess and evaluate the capacity of the hull to undergo a second life of twenty years on station. A final steel renewal plan and steel reinforcements were devised.'


preparing for co2 emissions monitoring

From August 2017 shipping companies with vessels trading to EU ports need to comply with new EU regulations on the monitoring, reporting and verification of CO2 emissions. Initially they have to submit ship-specific monitoring plans to verifiers for approval by the end of August 2017, with per-voyage monitoring set to start on January 1, 2018.
The EU Regulation on the Monitoring, Reporting and Verification of CO2 emissions from maritime transport (EU 2015/757) (MRV Regulation) lays down rules for the accurate monitoring, reporting and verification of CO2 emissions and other relevant information from ships above 5,000 GT calling at EU ports.
Article 4 of the EU MRV contains the principles and Article 5 together with Annex I contain the methods for monitoring and reporting CO2 emissions and other relevant information on maritime transport.  Annex II contains rules on the monitoring of other relevant information including distance travelled, time spent at sea and cargo carried (for passenger, ro-ro and container ships).
Each year the company with responsibility for the ship's operations has to report the results of the previous year's annual monitoring of aggregated CO2 emissions. The Monitoring Plan lays down the detailed monitoring rules to be followed when monitoring the CO2 emissions and other relevant information for a specific ship. Regular and at least annual checks of the MP are required to ensure that it reflects the nature and functioning of the ship.
Tecnitas provides a portfolio of services linked to emissions monitoring, including continuous emissions monitoring, e-tool E2 for computation of emissions and preparation of the Monitoring Plan.

News in brief...
