DESCRIPTION OF THE PACKAGED RIG

The drilling Rig consists in a mast with a crown block on the top used for the transmission and the support of the ropes which, thanks to the travelling block, transmit the vertical motion to the drilling string (a set of drill pipes, drill collars, bit and any other tool descended into the well). The mast consists in a structure of elements joined by broaching or of telescopic type. At a determined height, the mast supports the monkey board which consists in a work foot board for the operator who, during the well- running and pulling operations, hooks and releases the stands (set of three pipes) from the elevator. To the monkey board are fixed fingers which serve as guides and as retainer for the vertical stands, when these are rested on the skid of the drilling floor. The mast is Rigged up to a substructure made up of strong steel trusses. The aim of the substructure is to create a free space , of sufficient height and width, under the drilling floor, to allow the arrangement (settling) of the blow out preventers (B.O.P.). The rotatory motion, by means of which the bit drills the ground, is given (supplied) by the Top Drive. The Top Drive consists in an electric or hydraulic engine, which, supported by the rotary hook, runs along apposite races fixed to the mast and sets (impresses) the rotatory motion to the drilling string. The connection among the pump standpipes and the swivel assembly is realised with a rotary hose, of proper length, which offers the possibility to maintain the rotary string in movement, while the mud circulates (runs) in the well. The TDS is supported by the travelling block thanks to a strong hook. A wire line (drilling line), with an end fixed to the substructure of the mast, passes through the blocks of the crown block and the travelling block and then winds itself up on the draw work drum. The spinning of the drawwork drum causes the movement of the travelling block and therefore of the string. The drawwork is the machine which performs the functions of letting descend and of drawing up the pipes and hoses used during the drilling activity and the covering of the hole. The Rig is supplied with 3 mud pumps with pressure and capacity sufficient for the mud circulation. Thanks to a system of suction lines, the pumps are connected to the mud pits and, through an assembly of high pressure standpipes, to the swivel assembly, in order to introduce mud into the drilling string. The mud, as soon as it returns on the surface, passes on (shale) shakers where it leaves the cuttings incorporated during the well drilling and then, through a ditch, it returns in the suction pit. The generating sets are placed at a safety distance from the drilling mast and from the pumps. The equipment of an offshore jackup drilling Rig is completed by: • • • • • • • • •

Centrifugal pumps; Electric-agitators; Shale shakers; Blow out control equipment; Pipes rack; Chemicals rack; Living quarter with offices, accommodations, mess room, laundry, toilets, etc.; Lightning system; Safety and first aid equipment;

ACTIVITIES AND ORGANIZATIONAL STRUCTURE

2.1

DESCRIPTION OF THE DRILLING ACTIVITY

Exploration and production indicate the execution of a hole which, through the various ground layers, allows to reach either the prearranged (pre-established) depth, where the pool is supposed to be, or the already determined pay zone. In order to carry out the above mentioned hole, it is necessary to have a drilling Rig which, through a mast, a draw work, engines and pumps, allows the bit to rotate (to spin) and to penetrate into the ground. Connected drilling pipes long 9 Mt. approx. are added to the bit and allow the same to reach the desired depth. Into the pipes is pumped the mud which has the duty to offset the eventual rock pressure, to avoid caving of the hole walls, to lubricate the bit and to bring the ground cuttings grinded by the same on surface. As the bit has to be periodically substituted because of wear, in order to bring it back on surface it is necessary to pull out the pipes already used and to stock them vertically in an apposite pipe rack. After having substituted the bit, the opposite operation is carried out and the pipes are lowered to bring the bit back to the previous depth of work. The joining and the breaking-off of the above mentioned pipes take place using particular keys called rotary tongs, kept hanging (suspended) from the mast by lines and counterbalances, to which a twisting couple is impressed through a line activated (set in action) by the drawwork. Considering the remarkable weight of the pipes, in order to support and move them, a mast with a descending travelling block, movable through a system of lines, is Rigged up along the internal axle. The spinning of the bit is the result of the action impressed by Top Drive. The mud circulation into the pipes till the bit and its following ascent on surface through the annular space (wellpipes) is carried out through apposite pumps. The energy necessary for the lift, the spinning of the pipes and the mud circulation is supplied by generating sets. The main operative phases (stages) of the drilling activity are: Drilling activity It consists in impressing spinning and weight to a bit, to which connected drilling pipes are gradually added, till the reaching (achievement) of the desired depth. Note: With the use of the “Top Drive” system 27 Mt. of drilling pipes (stand) are added each time.

Operation It consists in two phases: pulling and running. Pulling

consists in recovering the drilling pipes and drill collars (one stand each time) and in stocking them in raking board in order to pull out the bit for its substitution, or for other operations.

Running

is the opposite of the pulling phase and consists in bringing the bit to the previous achieved depth, or in descending particular tools in the well. At the end of the bit run , the drilling activity is resumed.

Tubing and cementing activity Occasional activity prescribed by the drilling program prepared by the Operator. This phase is realised to cover the hole and to protect it from landslides and shrinks. Technically it is carried out descending pipes with a diameter inferior to the hole, with a technique similar to that used for the running, operating with a single pipe each time. At the end of the tubing the annular space between the hole and the pipe is partially or completely filled with cement slurry. These operations are carried out in co-operation with other contractor firms co-ordinated by the holder of the concession. Work Over The wells, after a certain period of exploitation, need some maintenance operations called “Work Over”. These operations consist in the well cleaning (servicing), through the substitution of the production horizon packer and of the string of production tubing as well as in interventions to improve the production.

METHODS OF RISKS ANALYSIS AND ASSESSMENT

3.1

CRITERIA ADOPTED FOR RISKS ANALYSIS

Foreword: The drilling activity is a dynamic activity which is carried out through a series of operations that goes from the Rigging up to the real drilling activity till the Rig tear down. The same will then be moved to another site, sometimes hundreds kilometres (far) away. The personnel should be able to carry out different activities, each of them can require specific capacities and knowledge. In particular, every member of the drilling crew can be called (appointed) to co-operate with the crane operator in order to unload the materials from the supply vessel, assemble the tubular material, carry out the maintenance of the pumps, blow out preventer (B.O.P.), equipment of the mud circulation system and drilling equipment, to take part in pulling out and running the drilling pipes and tubing, to use hoists, and so on. All these operations are carried out by the drilling crew. The remaining personnel carries out specific works such as the maintenance and the management (running) of the Rig. Moreover, we shall not forget that although the site area (even if it is not wide) presents the heart of the drilling activity in the drilling floor, the personnel, as it has been previously noticed, should work also in all the remaining areas of the Rig. The numerous duties of the personnel, their execution in different areas onboard, the impossibility to quantify the permanence in the various areas of the site, even in a purely theoretical way, suggested us that we should analyse the dangers of the drilling activity on the whole, rather than the dangers referred to the workplace (position) and exposure time, which, in any case, could be valued only approximately. Risk analysis Definitions: Hazard:

Intrinsic property or quantity of a determined factor (for example, work materials or equipment, work methods and practices, etc.) which has the potential to cause damages;

Risk:

Probability that the damage potential limit will be reached during the use, that is the exposure, of a determined factor.

Risk analysis

Assessment procedure of the possible damage extent as risk consequence for the health and safety of the workers during the execution of their tasks, caused by the occurring of a danger on the working place.

RISK MATRIX FOR THE ANALYSIS OF THE CRITICAL STATE

Once the hazards are identified for each task undergoing a risk assessment, they will be analysed to determine the Risk Value. Definitions of the terminology associated with risk assessment is included in the STD-COR-HSE 001 (standard to develop companies HSE MS and to establish risk), represented as: Risk = Consequence x Probability Consequences The evaluation of the consequences shall be qualitative, and the consequences shall be classified according to the following matrix:

Risk Value The risk analysis estimate is made of the consequences and probability of each hazard identified. The product of these two is defined as the risk value. The Risk Value is indicated as follows:

RISK VALUE Probability x Consequence = High (Unacceptable) - 15 to 25 = Medium (Acceptable subject to risk reduction measures / contingency plans be applied) - 5 to 12 = Low (Acceptable risk) - 1 to 4

Guidance on the consequences and probability of particular hazards are based around the simple matrix below:

DISCIPLINE PROCEDURE Rev.01

OFFSHORE DRILL SAFETY CASE Page 32 of 180

Selection of Suitable Risk Reduction Measures Risk reduction process must address the means of providing a solution in the following order : • Eliminate the risk by removing the hazard - “engineer out” the problem at source. • Reduce the risk by substitution of a less hazardous process, activity or substance. • Isolate (protect everyone) by effective engineering controls such as enclosing the hazard, removing the person from the hazard or reducing the person’s exposure time to the hazard. • Install protective devices such as guards, emergency stops and trip switches etc. • Enforce Permits-to-work, special rules and procedures to closely control the hazard(s) • Provide proper supervision, supported by training, instruction and relevant information • Provide Personal Protective Equipment only as a “last resort” and in support of the control measures 1-6 above. In addition, Saipem will introduce measures to control and reduce the potential hazards / risks in accordance with: • • • • •

Current local / international legislation. Client requirements Codes of practice. Recognised international standards. Saipem’s own methods of control as defined in the risk control hierarchy above.

Note: The above methods for determining Hazards, Consequences, Probability and subsequent Risks and Risk Reduction Methods, are to be used on the site where no other qualitative or quantitative method is available.

3.3.

DRILLING ACTIVITY RISKS ANALYSIS

The Rig drilling activities have been studied and evaluated to highlight all the possible risk involved during their execution . To analyse and take into consideration all risk involved during the various activity phases two different type of tables have been prepared : Activity Sheet and Hazard sheet. The activity sheet describes the different jobs and activities carried out on a drilling Rig during the all well operation. On this sheets a brief job description is done and all risk involved in the relevant job execution are summarised in the column “ key safety consideration”. The key safety consideration are therefore linked with the relevant Hazard sheet which have been prepared specifically for each type of hazard that may occurs on that particular activity. Risk evaluation reported on the Hazard sheet have been worked out using the risk matrix reported at point 3.2 Here following it is described in which way the hazard sheets and the activity sheets are linked:

JOB DESCRIPTION

The Top drive system is utilised instead of rotary table and kelly to drill out formation using stands of drill pipes which are normally picked up and stacked into the derrick at beginning of activity. Use of top drive allows a better control of the drilling activities and allows reaming operations while circulating in a safe manner. It allows also, in case of pipe being stuck, a better controls of jarring operations. The main advantage of Top drive system is due to reduce connection times and improved safety by means of hydraulic torque tool and presence of safety devices ( kelly cocks ) which are installed on the main shaft and hydraulically operated thus allowing the connection at any time at any height ( most important in case of kick through the drill pipes) reducing risks to personnel. He is connected to hydraulic and air power units via high pressure hydraulic hoses and air hoses, mud is normally pumped through it via Rotary hose connected at stand pipe manifold. The top drive system is a rotating , hydraulic and air operated tool and as a such it may be hazardous , routine inspections and greasing operation have be carried on height. While drilling with top drive the following risks should be taken into consideration:

Main swabs run on two welded beams on the template frame, while the secondary swabs run on the two beams belonging of the rig substructure. Such operation should be repeated up to it arrives at the center of the well. Before skidding starts, it needs to control that all hydraulic and pneumatic connections are disconnected, while the electrical wires must be positioned on the arm, joint with the rig moving. BOP must be lifted, shifted by one side and, finally, hanged by two tackles. Riser even must be lifted, so the extreme side is lifted respect the well plane and hanged by the block. The old slot must be covered by its original sheet. Cross deck must be removed or hanged by the crane. It is also important to control that no object can fall or be unhooked; causing damages to persons and tools. If pipe stands and drill collars are stowed into the derrick, it should tie its with ropes or chains. During the skidding, flow line will be hanged by the crane and, afterwards, adapted on the new position. This operation will be controlled by all crew, who will also verify the several phases, making sure of good result.

Hoses have to be protected to the free end with the Weco’s plugs, because it is necessary to avoid unintentional outlets, which can cause difficult situations for the environment. Each ones will have a lifting double sling (certificates), connected to a safety collar. The operation’s chief will wait the ok sign of the various departments (mech., drilling, etc.) before to begin the shipment/discharge. He will control that the hoses are correctly connected and anchored to the S.V. He will decide, after control of weather and sea conditions, to begin the shipment and discharge operations. For long time of shipment/discharge, the S.V. will have to anchor to the platform by mooring wire lines. The mechanician (for liquids) and the Tour Pusher or Derrickman (for dust) will control, with their tools (drills, manometers, levels, etc.), the load and they will give the advise to the responsible of the operations. Carried out the shipment/discharge operations, it will assure, before to recover the hose, that the line is without liquid or dusty residues, blowing air inside before disconnect. Crane operator will achieve the chief’s instructions, trying to make sure of people and materials. It will assure that, when the draught (and release) acts on the S.V., nobody has to be close. The chief will avoid fast movements of the crane pole, which could cause dangerous load swings. He will also control, together the responsible, that lifting tools are in order and certificates.
