DNV GL grants FLPS Approval in Principle

Published by
LNG Industry,

DNV GL has announced that it has granted Approval in Principle (AIP) to IHI Corp. for its floating LNG power station (FLPS) concept, after the design was found to comply with DNV GL’s class standards and other relevant industry standards.

The FLPS concept is a combination of a floating storage and regasification unit (FSRU) and a power plant. It is expected to be installed in locations with a rapidly increasing energy demand but where onshore infrastructure is not feasible or commercially viable.

The main functions of the FLPS are LNG loading from a visiting LNG carrier, regasification of the LNG, power generation using natural gas, and export of electricity to onshore grid. The FLPS is designed to be capable of remaining on location for up to 25 years without dry-docking.

IHI Corp.’s FLPS concept will use a single point mooring tower yoke for position keeping, if the jetty meeting the draft requirement for both LNG carrier and FLPS is not available.

The LNG is stored in two SPB® tanks (self-supporting, prismatic shape, IMO type B) developed by IHI’s joint partner, Japan Marine United Corp. (JMU), and contained within the hull of the FLPS.

Regasification takes place in the topside facility located on the deck of the FLPS and the gas is then fed to the power generation system, which uses a combined cycle consisting of gas turbines with heat recovery steam generators and steam turbine. The power is supplied to the onshore electricity grid by high voltage subsea power cables.

Conn Fagan, DNV GL Vice President, Business Development, Offshore Gas Projects, said: “We are pleased to be involved together with IHI in such a project, as it represents a move forward in developing technology which can be used to supply energy needs around the world. It has potential for many different applications, both short-term and also long-term, and will add a flexibility to the energy mix wherever it may be deployed.”
