There is an increased interest in the transportation of LNG world-wide which has prompted stakeholders along the LNG value chain to take a fresh look at how LNG is transferred to and from an LNG carrier, offshore, nearshore and berthed in ports and harbours.
The jettyless solution from Connect LNG is universal, meaning that it is perfectly suited for LNG offloading, loading and bunkering applications.
Connect LNG carried out the world's first jettyless LNG transfer in 2017 for Naturgy Energy Group.
World’s first successful jettyless transfer took place in 2017. We are here to challenge the status quo.
Removing the need for fixed infrastructure, capital expenditure can be drastically reduced.
Reduced Lead Time
First gas can be within months rather than years due to a simpler permit process.
Conventional LNG infrastructure
Terminals are required for both the loading and offloading of LNG into carriers. A terminal may consist of a jetty structure, loading platform, mooring and breasting dolphins and trestle for supporting the LNG pipeline. Offloading takes place via the loading arms where the tanker is berthed.
Locations which are not fortunate enough to have access to deepwater are fully dependant on seabed dredging for jetty construction, vessel mooring and turning access.This is a considerable cost to undertake, and for small-scale import projects, the investment required simply doesn’t make for sound project economics.
Loading and unloading
Location of the jetty terminal is dependent upon not only the requirements for the LNG tanker manoeuvring and positioning with respect to water depths, currents and ship traffic, but also with prevailing winds which may influence the location from a safety viewpoint.
The traditional shoreside loading/unloading of LNG to/from marine carriers may be prohibited due to proximity to populated areas, safety and/or environmental concerns. Also, the extension of an offshore jetty structure to support the transfer pipelines will, in all shallow water cases, require seabed dredging.
Jettyless LNG Transfer
The majority of the civil and onshore works associated with jetty or quay construction is eliminated with the jettyless UTS solution.
The UTS is essentially a floating jetty. The platform attaches to the side of the vessel and transfers LNG or other fluids to storage tanks with floating cryogenic hoses floats and is compatible with most vessel sizes due to the unique vacuum attachment system.
Capital spending and EPC project schedules can be dramatically reduced by avoiding large river, harbour or coastal engineering and construction works.
The UTS is DNV GL classified as an Offshore Loading Unit - obtaining permits from local authority and regulatory bodies is significantly simplified.
The UTS is a plug & play solution that requires no modifications to the LNG carrier and can connect any vessel or terminal.
How LNG reaches its consumers
Exploration and Production of Natural gas, onshore or offshore.
Produced gas is treated and liquefied through a super-cooled process, either onshore or on an FLNG vessel.
If onshore, LNG is then exported via a jetty or floating UTS to double-hulled LNGC carriers that have specially built tanks, to maintain cryogenic temperatures.
LNG is then shipped to the specific destination in double-hulled ships to receiving terminals where it is offloaded via another jetty or floating UTS, and then stored in heavily insulated storage tanks onshore.
The LNG is regasified through a heating process and distributed to domestic consumers – from power plants and industry parks to domestic use for heating and cooking.
Simplifying and alleviating bottlenecks
The UTS is a plug and play solution which allows for fast implementation into existing ports.
Replacing a jetty and other fixed infrastructure with the UTS can significantly reduce first gas and minimise project investment costs.
The UTS is a universal solution that requires no modifications to the LNG carrier and can connect any vessel or terminal.
It is a scalable solution tailored for small-, medium- and large-scale operations, providing flowrate capacities from 100 to 12,000 cubic meters per hour.
