Te system supplied by Cathelco consists of a control

panel which feeds an impressed electrical current to elliptical anodes mounted on the hull surface near each of the four ‘moonpools’. In operation, the current from the anodes ‘neutralises’ electro-chemical activity on the surface of the hull and prevents corrosion from occurring. Positioning the reference electrodes to achieve accurate

monitoring is an important aspect of the system design, as the electrodes measure the electrical ‘potential’ at the hull/ seawater interface and send a signal back to the control panel which raises or lowers the anode output. In this way, the correct level of corrosion protection is constantly maintained throughout the life of the vessel.

Subsea insulation

Alliance forms for

Trident insulation

BASF Polyurethane Solutions has announced a strategic alliance with Trelleborg Offshore US Inc, to develop and market ‘Trident’ thermal insulation for subsea applications. Trident is the next generation of glass syntactic polyurethane (GSPU) and enters the market as the new standard in GSPU for the insulation of subsea structures. Trident is the result of a strong collaborative effort to

combine BASF’s mercury-free ZEROHg technology with the polyurethane processing experience of Trelleborg Offshore. “[Te] announcement of the joint efforts from two

market leaders in our respective specialised fields is a huge step forward in our strategic alliance,” said Brian McSharry, president of Trelleborg Offshore US, Inc. “It is important to note that Trident insulation is not

only mercury-free; it enters the market with improved temperature resistance compared to current market offerings. Both companies are committed to continue to introduce solutions to the marketplace that leap frog materials available today. I am confident that our relationship with BASF will continue to thrive for the benefit of our oil and gas customers,” said McSharry.

Liquids transmission

GL Noble Denton

launches SynerGEE

GL Noble Denton has released a new soſtware product, SynerGEE Liquid Transmission, which stands to reduce costs for pipeline operators. Te two main cost factors in operating a pipeline are the

cost of drag-reducing agents (DRA) and the energy used to pump these liquids. SynerGEE provides short-term operational cost optimisation by optimising flow rate,

pump station operation and/or DRA concentration injection per batch at pump stations. “It is the only product on the market that can optimise these variables simultaneously”, said Shelly Young, vice-president of Soſtware Solutions Practice for GL Noble Denton. SynerGEE’s user interface provides a schematic of the

batches and the pipeline, allowing users to view past, present and future results of the simulation. Variables such as pressure, flow rate, power consumption and DRA injection rates are selected by the user for display on the results screen. Time and distance charts can also be used to view the results. Standard reporting provides the information needed for operational planning, with set points and equipment change strategies for upcoming hours of operation. Combining years of pipeline experience and expertise

with advanced mathematical modeling techniques, SynerGEE Liquid Transmission optimises the operational cost of transporting petroleum products through a pipeline. “The introduction of SynerGEE Liquid Transmission… marks another major milestone in our delivery of soſtware-based solutions that provide accurate, short-term liquid pipeline operations and planning optimisation,” said Young. “Our vision is to develop innovative soſtware solutions for our clients that improve their asset and business performance. SynerGEE will highlight operating plans that result in energy and DRA savings that will positively impact the bottom line.” GL Noble Denton offers a comprehensive portfolio of

soſtware solutions across the oil and gas sector. Soſtware solutions enhance the safety, performance and integrity of assets across their lifecycle and come with a range of consultancy, implementation and support services. Te SynerGEE modelling soſtware products can model large, complex, integrated, multipressure-level systems for the oil and gas industry that include regulators and compressors. Users have full control over the gas constraints (gravity, heating value and viscosity), friction factor calculations and heat transfer methods. SynerGEE provides various flow equations (equations of state) and allows for each flow equation to be assigned as a session default or on a pipe-by-pipe basis.
