• • Environments taftquardi

(1) General

The goal of this Exploration Flan ix tha gathering of aora Inforaatlon on tha geology of the leaae area, in a aafe aanner, with minimal disrup­tion of the environment. Varloua rulea, reguiationa, codes, laws and practicea have been developed over the years, which will aasist the operator to conduct operatlona in this aanner. OCS Order Number 7 speci­fically deals with the environmental safeguarda and aafety of the drilling and production operatlona. The regulations are strictly adhered to by Samedan.

Environmental safeguerds are built Into the the operations ln several wayai ln the original design of equlpaent and ayotea of operatlona, ln tha training of personnel. In the preparation of procedures for opera­tlona and also in the procedures end availability of equlpaent for reme­dial actlona ln cases of emergencies.

Operetlona will be conducted under the conditlone described on the Application for Peralt to Dlacharge on file with the Minerala Management Service. Samedan conducts monthly tests to ensure that liquid weetea diacharged into the Oulf of Mexico comply with S.P.A. Regulations.

(2) Invironmental Safeguards in the Deeign

The drilling unit is built to prevent pollution of the Golf of Mexico by utilising a systea of curbe, gutters and surface dreina which direct a l l fluida to a containment systea. This systea recovera hydrocarbona before water is discharged into the Gulf cf Mexico.

Liquid waata material, including sewage from the living quarters will be treeted ln a Minerals nanagement Service approved sewage plant on the drilling unit prior to dlacharge into the ocean, solid waete materials are compacted and traneported to ehore for diapooal.

Drilling operatlona are monitored by the Samedan representative on board. Nud and drill cuttlnga will ba treated to remove oil prior to dlacharge into the Gulf of Mexico. Xteaa that cannot be treated pro­perly will be transported to ahore for disposal.

(3) Training of Pereonnel and Procedures

Regular training of operations personnel is a necessary complement to the pollution prevention fee ture a in the deeign of equipment and opera­tions. Operetor awarenese la achieved by regular trelning and enfor­cement of procedures. The drilling unit is inspected dally. A procedure for the reporting of and dealing with oil spills has been establiahed by Saaedan in eccordance with the requirements of OCS Order Number 7, which is incorporated in Saaedan "Disaster Contlngenecy Plan*.

C . Safe ty Postures

As l e the case with the environmental safeguards, safety aspects must be a combination of design, operator awareness end the a v a i l a b i l i t y of s u i t a b l e emergency equipment. Over the veers , the O i l Industry and the Pederel Government has lseued e considerable mseber of aten tarda, recommended pract ices end lewa governing minimum requiromenta. Deeign of equipment for Samedan'a operetlons requires the appl icat ion of a l l s v s l i a b l e standards in tha a t r i ••est manner. The most important of theaa are l i a t e d belowt

...OSHA • i.OCS Orders of the Nine r a l e Manageaent s e r v i c e . . . A P I Stenderde end Recommended Pract lcee . . .ASME Codes .. .ASTM Standards . . . a l t S I Standarda . . . R I S C . . .American Helping Society ...NPPA (NBC)

Safety systems ere incorporated in the design of equipment and opera­t iona l procedures as required by the OCS Ordera of the Minerals Nanagement Serv ice . OCS Order Number 2 s p e c i f i c a l l y provides de te i l ed in foraa t lon on the d r i l l i n g operetlona and Saaedan adheres s t r i c t l y to these r u l e s and regulations.

Automatic gas and f i r e detect ion ayeteaa are incorporated in the un i t to alarm operetlone pereonnel in caae of emergencies. Equipment to deal with emergencies ( l i f e ves t s , r a f t s , buoys, f i r e extinguishing equipment, l i f e boata , e t c . ) i s loceted s t r a t e g i c a l l y on the d r i l l i n g unit* Frequent t ra in ing sessions ere held to keep operetlone pereonnel a l e r t and f a m i l i a r with procedures and operetlng ins truct ions for equipment.
