Hydrogen gas is called to play a key role in the energy transition and initiatives needed for a
decarbonization of the economy. Initially, assets for energy storage and transport were developed and qualified for the purpose of the oil and gas industry, especially natural gas. Repurposing of existing assets for the use of hydrogen gas, or creation of new dedicated hydrogen transport and storage infrastructure, is a great challenge for future hydrogen projects. It includes the qualification of steel materials under
hydrogen gas environment.

Stress relaxation cracking (SRC) is a failure mechanism known to occur in austenitic stainless steels and nickel alloys operating at moderate to high temperatures.

Typically, SRC failures tend to occur under the following conditions: ^1-6 1. Susceptible material: 800H, 347H, 617, etc. (typically materials with low creep ductility) 2. High residual stresses: Hardness > 200 HV (welded thick section) 3. Specific temperature range: usually between 500 °C (932 °F) and 750 °C (1382 °F).

Under these conditions, component stresses are relieved by time dependent inelastic deformation.3 In susceptible materials, this process occurs by intergranular cracking and is essentially a creep mechanism.^2-6 In this respect, materials with low creep ductility tend to be prone to this type of damage mechanism. On the other hand, materials that have good creep ductility can tolerate the inelastic strains due to relaxation without cracking.³

The multicomponents of the produced water often results in the formation of the solid solution, such as BaxSr1-xSO4. The suspended solids collected from industry often show the presence of Sr2+ in the BaSO4 scale, indicating the formation of BaxSr1-xSO4 solid solution. Thus, it is important to study the solubility, kinetics and inhibition of the solid solution to have a better prediction of the sulfate scale deposition rate and amount.
In this research, we will mainly focus on the effect of the incorporation of Sr2+ on the deposition rate of BaxSr1-xSO4 solid solution scale. The flow through system with two different reactors was used in the experiments. From the experimental results, we can find that the deposition rate of the BaxSr1-xSO4 solid solution decreased significantly with the increase of strontium concentration at a constant barium sulfate supersaturation. The deposition rate decreased up to six times when strontium concentration in aqueous phase increased from [Sr2+] = 0.5[Ba2+] to [Sr2+] = 8[Ba2+], all with SIBarite = 0.9. The decrease of the SI of the BaxSr1-xSO4 solid solution was found with the increase of Sr2+ in the aqueous phase. This might be the reason for the retardation of Sr2+ on BaxSr1-xSO4 deposition rate.

Structural FRP Applications on Topside Projects – How do CAPEX and OPEX costs really compare to conventional carbon steel?

Product Number: MPWT19-15325

Author: Simon Eves

Publication Date: 2019

$0.00

Offshore projects today are demanding ever more reductions in both CapEx and OpEx. Tertiary structural products (eg handrails, gratings, ladders and platforms) made in steel may at first seem to be the lowest cost option, but steel is heavy and eventually suffers from corrosion which can be a significant drain on budgets and resources.
The benefits of FRP (fiber reinforced polymer) tertiary structural products for offshore oil and gas projects can be very significant, with substantial weight reduction, lower installation costs and minimal maintenance. But how can these recognized FRP benefits against steel be translated into actual CapEx and OpEx savings when used in oil and gas projects?
This aim of this paper is to offer answer to this question, by presenting a study of the projected Whole Life Cost and Value Proposition for the MARRS Offshore FRP Handrail using data drawn from the recent BP Clair Ridge Project.

Opportunity crudes are generally defined as petroleum crudes bearing a high level of sulfur, metals, or total acid number (TAN). These crudes are typically offered at a discounted value. Thus, refining such crudes carries with it a lucrative incentive. However, due to the above-mentioned characteristics, processing such crudes presents numerous operational challenges as well, such as naphthenic acid corrosion, which is commonly associated with the high TAN content in these crudes. In refinery units such as the crude distillation tower, these carboxylic acids react with the iron atoms of the metal surfaces to produce oil soluble iron carboxylates.^1,2 The continued formation of such complexes would then erode the metal surface. Equipment failure due to such corrosion results in shutting down a large segment or the entire refinery. Therefore, establishing a means for mitigating this type of corrosion is paramount for processing crude oils with an elevated TAN due to naphthenic acids.

Campbell County Utilities and Services Authority in Lynchburg, VA installed a 12-inch ductile iron water pipe in 2008. It is the main water supply to the Concord area of Campbell County and Appomattox, VA. Since 2018, 16 leaks have occurred on the pipe within a two-mile length concentrated at two general locations. The pipe parallels fiber optic communications cables on both sides of the street but has no other potential interference sources. The pipe is cement mortar lined but is not externally coated, bonded or cathodically protected. A study was performed to determine the cause(s) of the leaks and the most appropriate remediation. The study consisted of soil resistivity and potential gradient measurements along the pipe run and excavation of the pipe in the most aggressive area and removal of a length of pipe for detailed inspection and chemical, metallurgical, and mechanical testing. This paper describes the study results in detail and the mitigation recommendations.
