HHI deepwater FLNG hull design receives ABS AiP

Hyundai Heavy Industries’ (HHI) Deepwater Floating Liquefied Natural Gas (FLNG) hull design has received Approval in Principle (AIP) from ABS.

The hull design is based on LNG carrier designs, combined with the requirements for FLNG production, such as structural reinforcements to take topside module load and a hull designed to allow up to 25 years operation without dry-docking.

HHI confirms this newbuilding conversion FLNG hull design for offshore application can be constructed for about 80 per cent less than the cost of a conventional FLNG hull.

The FLNG hull design was developed by combining the latest industry trends with shipbuilding practices and ABS rules to maintain high safety standards. The design features a Barge-shaped Hull, a GTT Mark III containment system with storage for about 192,000m3, and provisions to accommodate an internal turret and 45,000-ton of topside modules to deliver 2.5 MTPA of LNG.

A low cost Near Shore FLNG Hull was developed and achieved ABS AIP in 2017. The same team from HHI and ABS has now worked to deliver this harsh environment Deepwater Hull to meet increasing market demand.

Hyungkwan Kim, executive vice president, shipbuilding division, HHI said: “In the current emerging gas market, a ready-to-convert offshore FLNG hull, with ABS certification, at affordable CAPEX is an important product for monetisation of gas reserves around the globe. This new line-up from HHI responds to the requirements of operators and combines HHI’s unparalleled expertise in shipbuilding with ABS’ stringent safety evaluation.”

ABS vice president global gas solutions, Patrick Janssens added: “ABS is the market leader in the classification of offshore drilling and production units, including FLNG vessels, with more than 150 floating oil and gas facilities in the ABS-classed fleet. We have partnered in leading innovation in the offshore sector for 60 years, and we are proud to enable this latest advanced deepwater FLNG Hull approach from HHI.”
