Waga Energy to deploy
RNG technology
in Quebec
Waga Energy has been enlisted by the
Mauricie Residual Materials Management Board
to deploy its landfill gas-to-renewable natural
gas (RNG) technology at the Saint-Étienne-desGrès
landfill in Quebec, Canada. The green gas
produced will be purchased by gas distributor
Énergir for injection into its gas grid onsite. The
landfill gas-to-RNG project, which will run for at
least 20 yr, will be the first in Canada to use the
WAGABOX technology, which was developed to
recover landfill gas as biomethane.
The recovered biomethane will be upgraded
into grid-compliant RNG by a WAGABOX gas
treatment unit built onsite. The landfill gas at
Saint-Étienne-des-Grès was previously captured
and burned in a flare. Designed to process
3,400 m3
/hr of biogas, the WAGABOX unit
will produce 468,000 GJ/yr of renewable gas,
corresponding to the consumption of 8,000
local households and preventing the release
of 23,000 tpy of CO2
into the atmosphere. The
project is scheduled to be completed by 2022.

Servomex upgrades flammable
gas analyzer
Servomex's SERVOPRO MultiExact 4200 analyzer provides
high-specification multi-gas analysis of flammable gas samples and
trace contaminants in applications including HyCO, syngas, hydrogen
production and gas transfer applications.
Utilizing paramagnetic, infrared and gas filter correlation sensing
technologies, the MultiExact 4200 analyzer measures up to four gas
streams simultaneously, with percentage measurements for O2
and CO. It can also be configured to measure percentage CH4
ppm-level CO, CO2
, CO2
and
, CH4 and N2
O.
The analyzer has a built-in LCD screen and provides alarm, fault
and calibration logs. An automatic calibration option reduces ongoing
operational requirements. Other benefits include minimal maintenance
requirements and a low cost of ownership.
GTT upgrades NO96 technology
GTT has developed the NO96 Super+, an evolution of the NO96
Cargo Containment System (CCS), which has received an approval in
principle from Bureau Veritas.
The NO96 Super+ technology integrates insulating reinforced
polyurethane foam panels instead of plywood boxes to reduce the
heat ingress inside the tank. Glass wool flat joints are also inserted
between adjacent foam panels to optimize the behavior of the system
and ensure it the best thermal performance.
These modifications allow GTT to further reduce the evaporation
of the cargo during operations, with NO96 Super+ offering a
guaranteed boiloff rate of 0.085 vol%/d for a standard LNG carrier
with a capacity of 174,000 m3
are possible for larger capacities, such as 200,000 m3
. Further reductions down to 0.08 vol%/d
.
with Kongsberg Digital and
Alpha Ori Technologies for a
digitalization partnership to
realize digital capabilities that
enhance efficiency and reduce
the environmental footprint
of LNG carriers (LNGCs)
and floating storage and
regasification units (FRSUs).
The agreement encompasses
several projects, including utilizing
a common data management
platform and developing a
maritime digital twin and digital
processing models. The aim of
the partnership is to enable the
acceleration of technologies
needed for future-ready LNG
carriers and FSRUs by leveraging
Kongsberg Digital's data
infrastructure technology, Vessel
Insight, together with Alpha Ori's
SMARTShip digital applications
and BW LNG's operational
expertise and assets for piloting a
maritime digital twin and a realtime
decision-support system.
A pilot project has been
established to develop and test
a maritime digital twin developed
for the BW Magna FSRU,
utilizing the Vessel Insight data
infrastructure, Kognifai digital
platform and maritime simulators
from Kongsberg Digital, as
well as value-adding expert
applications from Alpha Ori.
The pilot will illustrate an
example of the benefits of
digitalization for the industry.
Silverstream
Technologies
completes
LNGC trials
Clean technology company
Silverstream Technologies
announced that its pioneering
air lubrication system, the
Silverstream System, has delivered
significant fuel and emissions
savings during testing on the Shellchartered
170,000-m3
LNG carrier
Methane Patricia Camila.
Following operational testing
of the retrofitted technology,
Silverstream and Shell's engineers
demonstrated 6.6% net savings
generated by the Silverstream
System. The technology was tested
at various vessel speeds during
Methane Patricia Camila's normal
operations, to calculate fuel and
emissions savings.
The Silverstream System
enables fuel and emissions
efficiencies through its unique
design. The technology produces
a thin layer of microbubbles along
the full flat bottom of the vessel,
reducing frictional resistance
between the water and the hull.
The system was successfully
retrofitted on the 2010-built LNGC
during its October 2020 planned
dry docking at the Sembcorp
Marine Admiralty Shipyard in
Singapore. From design through
to installation, the system was
reviewed and approved by ABS in
accordance with its guidance note
for air lubrication technology.
