Graphene used to beat pipeline corrosion
Graphene-laminated pipes could reduce corrosion in the oil & gas industry. Researchers at The University of Manchester and TWI have discovered ways of using graphene to prolong the lifetime of pipes. The team has found a way of
incorporating graphene into a polymer liner used in pipes that transport crude oil and gas from the sea floor. The pipes are generally made of internal layers of polymer or composite and external strengthening steel. Within
these pipes, fluids may be at very high pressure and elevated temperature. In situations where CO2
, H2 S and water
permeate through the protective barrier layer of the pipe, the steel may corrode causing the pipe to lose strength over time, leading to a risk of catastrophic failure. The researchers found that if the
graphene was mechanically mixed with the plastic, or if a single layer of graphene were applied, gases were still able to pass through. However, by
12 MONTHS LTI FREE FOR DRILLING WASTE FIRM
US, Middle East and Africa where more than 700 staff are employed. The announcement follows
Specialist drilling waste management company, TWMA, has completed 12 months of operations without any lost time incidents (LTI). The milestone, which is equivalent
to more than two million man-hours, encompasses 11 bases across the UK,
TWMA’s Egypt operation celebrating eight years LTI free in May. In 2018, TWMA launched its Stay Safe Programme
designed to guide employees towards incident-free operations. It empowers all employees to intervene whenever they see an unsafe act and has significantly contributed to TWMA’s strong safety culture.
Extended blow out preventer hoses
PROTECTING AGAINST OIL SPILLS
EPetal17, the latest Marine Breakaway Coupling (MBC) launched by Gall Thomson, has set new standards for lightness, precision and performance, to the extent that the company describes it as “the most advanced protection against offshore oil spills in the world.” Gall Thomson MBCs are
Eaton has announced an extension to its range of blow out preventer (BOP) hoses which meet or exceed the requirements of the demanding AP1- 16 drill well specification. The newly released EC556 BOP
hose forms a critical part of oil and gas drilling and exploration equipment, where reliability and safety are the number one requirements for in
operation performance. The EC556 BOP hose is certified to withstand fire, high heat and pressure and is tested, rated and approved Lloyd’s register. “Building on a strong legacy of
fluid conveyance product innovation, our EC556 portfolio of blow out preventer hoses are designed to offer outperform the competition,” said Johannes Kammerlohr from Eaton.
designed to minimise risk of offshore oil spills due to tanker breakout of pressure surge during hose transfer operations. The Petal17 is the result of over
40 years of in-field experience and major capital investment. Much of this investment has targeted product development. Petal17 is engineered with a range of innovative features that takes Petal Valve MBCs to a new benchmark of performance.

laminating a thin layer of graphene nanoplatelets to polyamide 11 (PA11) - a plastic often used in these liners - the team was able to produce structures that behave as exceptionally good barriers. The multi-layered laminate
structures were tested at 60°C and at pressures up to 400 times atmospheric pressure, and were shown to reduce CO2
permeation by over 90% compared to PA11 alone, while permeation of H2
S can be reduced to undetectable levels.
