SAFETY MOMENT

TEAM WORK

FOCUS: Tenets of Operation #10

“Always involve the right people in decisions that affect procedures and equipment.”

The clip below illustrates the importance of recruiting the right mindset in your team in critical decision-making processes:

“To do it safely or not at all”“There’s always time to do it right”

SAFETY MOMENT (cont’d)

Story:

Twin carries injured sister across the finish line at 800-Meter race

Chloe and Claire, 13, were competing for the 800-Meter race at the Southern Illinois State Track Meet when Chloe felt something pop and went down

Claire didn’t call for help, nor did she wish her sister better luck next time and run off to finish the race. She did something else entirely

“They didn’t win the race, but they won the hearts of everyone in the audience,” their Coach Ted Crail, said, according to the Associated Press. “I’ve been coaching for 20 years. This was the first time I ever had tears in my eyes at one of the meets.”

“It’s about showing compassion, love and sportsmanship, even if you lose and help somebody it’s still worth it,” Claire told KTVI

Moral:

It’s about sportsmanship

Teamwork doesn’t have a “U” in it. It’s also about lifting others with yourself

Food For Thought:

What is our definition of “WINNING”?Source: The Huffington Post

ESCRAVOS EXPERIENCE: DEHYDRATION UNIT & TANK FARM

The Escravos Terminal Dehydration Unit receives crude oil from North Offshore Area, South Offshore Area, and Onshore Area Facilities

The Dehydration unit undergoes two treatments:

The Water Treatment

The Oil Treatment

The primary function of the Dehydration Unit is to receive crude oil from various production fields and treat to meet export specification of ≤ 0.50% BS&W

The Escravos Tank Farm (Control Room) has a primary function of storing and monitoring the quality and quantity of the processed crude oil from the Dehydration Unit

It also works with the export group and relevant government and cargo agents to ship export grade oil to customers (BOP, NNPC, Warri). There are floating and fixed roofs. The quality is measured in two folds (fiscalization): composite and bottom product

ESCRAVOS EXPERIENCE:LABORATORY

The Escravos Laboratory provides world-class analytical services across the entire spectrum of asset management, crude oil, natural gas and produced water processing, quality assurance, equipment reliability and environmental management

The five units within the lab:

General Testing Lab

Environmental Lab

LIMS & Quality Assurance/Quality Control

Gas & Gas Liquids Lab

Utilities

They carry out quantitative and qualitative analysis on samples taken at intervals to ensure that processed crude meet export specification of ≤ 0.50% BS&W. Support Dehydration and offshore fields in analyzing the produced water to meet DPR regulations

The other parameters they analyze are:

API Gravity

Pour Point and WAT

TAN

Salt Content

THC

Offshore- 40 ppm

Onshore- 10ppm

High ppm?

EXPERIMENT:

to determine the hydrocarbon level (ppm) in the effluent water

Injected water and formation water in wells

Examples of Scales:

- Calcium Carbonate

- Calcium Sulfate

- Strontium Sulfate

- Barium Sulfate

Geochemistry Lab

Gas chromatography

-Finger Printing

-Mobile Phase

-Stationary Phase

-Read Out

ICP (Inductively Coupled Plasma) Spectrometer

-Used to analyze the metal content of the water. It uses UV light.

ESCRAVOS GAS PLANT

The Escravos Gas Plant is a facility designed to process natural gas and produce Sales Gas (C1 and C2), Liquefied Petroleum Gas ,LPG (C3 and C4), and Condensate (C5+). The Sales Gas is sold to Nigerian Gas Company (NGC), the LPG is transported to Floating, Storage and Offloading (FSO) vessel, and the Condensate is transferred to Escravos Terminal (prev.) or Escravos Gas to Liquid (EGTL)

LPG extraction is accomplished by cooling of the feed gas sufficiently to condense most of the LPG and condensate. The condense liquids and gas are then separated followed by fractionation into LPG and condensate

LPG produced is sent to the storage spheres in the facility before onward transfer to the offshore Floating, Storage and Offloading Facility for export. The condensate previously was sent to the Terminal area for spicing up the treated crude oil

It has five storage spheres:

-Alpha

-Bravo

-Charlie

-Delta

-Echo

PROCESS ENGINEERING

Process engineering is the branch of chemical engineering that addresses the design, synthesis and operation of chemical or manufacturing processes in which raw materials are converted into products. Chemical engineers:

-develop new processes or modify existing ones in order to optimize facilities

-reduce costs or maximize profit

-improve operations with respect to flexibility, reliability, energy efficiency and safety

-ensure quality control and address environmental impact

I worked on a piping and instrument diagram (P&ID) for the first time, and was able to identify different types of valves in the diagram

I also learned about the how to measure the size of the fluid leaving a valve through the inches shown on the diagram
