EVALUATION ON COST AND RISK ASSESSMENT OF OFFSHORE DRILLING WASTE DISPOSAL TECHNIQUES

Abstract

The offshore drilling industries has been facing litigations and down time in operations due to noncompliance to regulatory measures as well as applying inadequate friendly and cost-effective
offshore disposal techniques. This has affected drilling operations in many ways such as impacting
water ways disastrously with various contents of drilling wastes from their operations of inadequate
disposal techniques, morally affecting personnels as a result of financial hardship due to
disengagement at difficult times inappropriately and most importantly affecting the organizations
business due to pressures from government environmental agencies, litigating and terminating
operations for not operating on best practiced engineering techniques. This has made this journal
essentially important for organizations to carry out more studies on the best offshore drilling waste
disposal technique to avert aforementioned disadvantages and thereby operate on a more guided profitable and risk-free procedures. In this paper, I therefore evaluate three organizations operation performance on offshore drilling waste disposal techniques by raising questioners and assessing organizational reports (e.g. Litigation report) and the risk in operation. The Organizations are Shell
development Company (Snepco), Transocean and Baker Huges all of Nigeria operations on offshore
drilling waste reduction and disposal techniques. These techniques include zero policy, Seabed
injection and Bioremediation techniques which are majorly world best practice. The intent of this
journal is mainly aimed at comparing and evaluating, Zero discharge policy, Subsea injection and Bioremediation technique on their economic and risk impact as objective of identifying the
importance of each, assessing the positive impact and profitability on a measurement of strength
and weakness. The sample size for each organization cut-across four sources on average of 10 personnel from production superintendent, Chief driller, Safety superintendent and Deric Operator
in accordance to each organization as stipulated in the questionnaire for three years (2018 – 2020).
Primary and secondary data indicating Zero policy disposal techniques response from the three
organizations (Shell, Transocean and Baker Hughes ) as having number of personnel response on Economic cost low 86 and high 34 while on Risk is having personnel on low response number 84
and high response 36; Seabed Injection personnel number response on Economic cost low 22 and
high cost 98 while Risk is low 48 and high number response as 72 while Bioremediation Economic
cost low response 26 and high 94 while number responses on low Risk is 48 and high as 72. These
results indicates that Zero policy of offshore drilling waste disposal both on economic cost and risk to Organizations is better operated with minimal challenge of compliance without compromise to rules and regulations. In conclusion, synergizing with literature reviews such as Norwegian oil
company Equinor implemented zero policy Technique and achieved a 99.9% reduction in offshore waste disposal and Nigeria enforcement and monitoring forcing most offshore companies to comply to Zero policy technique by Nigerian Marine time administration and Safety agency (NIMASA) making zero policy techniques as best in control of offshore waste disposal.
