Company Overview

LATTICE Technology (LT), a technology and knowledge-based company founded in 2012 in collaboration with KAIST, has been developing several new technologies that provide unique and simple solutions to global LNG infrastructure spanning from LNG storage to mega floater positioning.

LT is pleased and proud to present its proprietary Lattice Pressure Vessel (LPV), the world’s first prismatic pressure vessel for LNG storage. The LPV technology has been granted approvals from the major classification societies (KR, ABS, ABS Consulting, DNVGL, LR, BV, and NK), and demonstrated successfully by building and testing four proto-type tanks. After signing a license agreement with Hyundai Heavy Industries in 2016 and closely collaborating with other qualified tank fabricators and engineering companies as well as promotional partners, LT is now vigorously reaching out into the global markets with LPVs as LNG fuel tanks and cargo tanks.

Classification of IMO LNG Tanks with Critical Requirements


Backgrounds of Development

Lattice Pressure Vessel (LPV) has been planned and developed with the ultimate goal of providing a solution for prismatic pressure vessels which fully combine the space efficiency of the prismatic shape of non-pressure tanks with the load-carrying capability of cylindrical pressure vessels.

Common Misunderstandings and Truths of LPV

Misunderstandings Truths

Prismatic LPV cannot bear pressure?No. The smartly designed internal lattice structure enables LPV to carry internal pressure load very effectively.

LPV is Type B tank since it is prismatic in shape?

No. LPV is a Type C (or Type C-equivalent) tank with design pressure beyond 20 barg with fatigue life satisfying Type C requirement.

LPV is much heavier than a cylindrical tank?

No. Round Wall LPV (RW-LPV) is as light as a cylinder or a bi-lobe tanks with much larger volume efficiency.

The internal structure of LPV could significantly reduce the internal space for fluid?

No. The volume fraction of the internal structure is 0.5% ~ 2% since the main internal structure parts are about 10 mm thick with spacing larger than 3m.

LPV is extremely difficult to fabricate?No. Four prototype tanks have already been fabricated without any practical difficulty and passed tests successfully.

Due to the increase in shell thickness proportional to volume, LPV is not highly scalable?

No. The shell thickness of LPV remains constant and is independent of volume under a given design pressure, consequently, it is fully scalable without size limit.

The cross section of LPV must be square?

No. Unlike cylinders the aspect ratio of LPV in three dimensions are free to change. Moreover, the cross section can be polygonal.

There must be a lot of stiffeners outside the shell of LPV?

No. Stiffeners are placed on the inside of the shell with sufficient spacing for welding work; hence the stiffeners do not require additional space.

LPV is structurally unstable and vulnerable to fatigue / distortion?

No. The lattice structure provides structural redundancy and mitigates dynamic loads, making LPV stable and strong against fatigue and crack propagation.

Construction material for the LPV is limited?

No. The choice of material is freely a matter of application and economics; alternative materials are available for cryogenic applications as well as others.


Representative Models

The Flat Wall LPV (FW-LPV) guarantees the maximum volume efficiency with small corner radius. As the corner radius increases, both the volume efficiency and weight decrease, and the LPV evolves into the Round Corner LPV (RC-LPV) and finally becomes the Round Wall LPV (RW-LPV) whose corner diameter is equal to its height. The RW-LPV is as light as Cylinders or Bi-lobes.

Conversion of Used Ships into More Valuable LNG Services

An approach to cost reduction for the small-scale LNG projects is to convert used ships into

LNG carriers and bunkering shuttles. The LPV provides a customized solution, fitting the

available space simultaneously maximizing the cargo volume and ship’s stability.

Case Tank for Very Large Container Carrier

BOG that should be handled by large LNG carriers

· Large LNG carriers has the BOG-dedicated systems (GCUs, reliquefaction systems, dualfuel

boilers) and on-shore terminals take care of all the BBOGs from the carriers

BOG during bunkering operation



The design vapor pressure should be at least 1.5 barg for “no BOG venting" during normal and bunkering operation.

No BOG venting from Type C tank

BOG loss from Type B tank increases with time.

· The BOG handling is much more difficult for the LNG-fuelled ship than the large LNG carrier

with dedicated BOG handling systems for the normal operation.

· The steadily generated BOG (NBOGSteady) from non-pressure tanks is just one of the several

BOGs and should not be regarded as the design case for the BOG handling system.

· The “BOG Holding Concept” for non-pressure tanks makes no sense, leading to a disastrous

consequence.

· To prevent the BOG venting even for the bunkering operation, the design vapor pressure

should be 1.5 barg or higher.
