Properly connected: A safety net for gas extraction

With the Ichthys LNG Project, Japanese energy company INPEX is opening up the largest discovery of liquid hydrocarbons off the coast of Australia in 40 years.

Fifty underwater drilling holes connect natural gas and condensate deposits with an enormous floating production storage and offloading unit (FPSO). From there, a pipeline of almost 900 kilometers stretches to the central processing facility (CPF) in Darwin. The offshore and onshore facilities are among the most modern in the world.

Safety engineering is provided by HIMA Paul Hildebrandt GmbH, headquartered in Bruehl, Germany. The company is supplying 430 control cabinets, including fire and gas protection systems (F&G), high-integrity pressure protection systems (HIPPS) and the connections to all relevant facilities.

Modular mammoth project

For HIMA, the key challenge is not the spatial and technical size of the project or the material used. Rather, it is the coordination across national borders and cultural differences. Other important factors include a strict time schedule between engineering input and acceptance, as well as additional design modifications that must be made in time for subsequent operations. Project management coordinated from Bruehl synchronized the numerous interrelated process steps over several years, enabling successful implementation.

From the initial planning phase to the final acceptance

Prior to the start of the contract, HIMA experts and the basic process control system (BPCS) supplier tested and validated hardware and software functions. The HIMA team dealt primarily with the engineering and the design. The aim was to clarify specifications in order to minimize subsequent plan corrections and the additional time this would involve. Specific applications and various interconnection possibilities of field devices were considered from an upstream perspective.

The onshore and offshore facilities and the pipeline are connected to a total of 25,000 safety-related input and output points. Safe networking was implemented using HIMA's safeethernet protocol. Cybersecurity and network management includes the installation of associated hardware and components such as smoke detectors in employee living accommodations. Numerous workstations and servers, along with an additional recovery system, are other components of the safety solution.

In addition to ensuring safety, HIMax® safety controllers from HIMA provide uninterrupted systems operations so as to maximize system availability and productivity. The safety systems comply with IEC 61508 and IEC 61511 standards and meet SIL 3 and SIL 4 requirements. HIMA Planar4 controllers used on the project can achieve SIL 4, the highest possible safety standard, in compliance with IEC 61508.

Worldwide coordination

Of the five HIMA locations involved in the project, Singapore is second only to Bruehl in strategic significance. In terms of worldwide coordination, Singapore offered the shortest routes for all parties involved. In addition to INPEX representatives, HIMA safety engineers and the control system manufacturer, the three contractual partners for engineering, procurement and construction (EPC) are represented on site. All contractual partners have occupied one building complex in order to communicate directly and efficiently.

In Singapore, function tests of all safety systems were performed on more than 1,200 control cabinets. In addition to the cabinets supplied by HIMA, 800 cabinets were supplied by the BPCS supplier and contractual partners. At the same time, safety engineering activities were distributed over three floors: one floor each for the semisubmersible platform, the liquefaction facility and the onshore facility. All facilities achieved 100 percent acceptance in the prescribed time.

Prepared for the future

HIMA’s ability to adapt over the years to the growing cost pressures and new complexity in plant engineering put it in position to win the Ichthys project. Changing with the times also meant developing modular, commercial off-the-shelf (COTS) systems. During large-scale projects and under extreme working conditions, COTS systems ensure higher production quality, lower prices, shorter implementation times and less effort at the construction site.

Today’s new complexity applies to more than technology. In the case of functional safety, the operator must also comply with a multitude of constantly changing laws, guidelines and standards. A functional safety management (FSM) system must be established over the entire life-cycle - from the initial design and implementation right up to the production process. Tailor-made safety solutions normally provide the operator higher system availability, lower maintenance costs and, not least of all, better insurance terms.

The Ichthys project: from discovery to development

The gas field off the coast of Australia was discovered nine years ago. The evaluation was made one year later. The selection of Ichthys for the preliminary project was made in 2010. The first contracts were concluded in 2012 and adjusted in the following years. In 2014 and 2015, various types of building work and the installation of compressors and heating units were carried out. Preparation of the safety engineering for the sea transportation from Singapore to Australia is currently in progress. Transportation will be initiated before August, if feasible, as weather conditions will be too severe later due to seasonal cyclones. By the end of 2016, 8.4 million tons of liquefied gas (LNG) should be extracted for the Asian market.
