INTRODUCTION As we know, oil and gas is the most popular fuel in industrial age. We can’t deny that the world needs oil and gas for human life, it makes oil and gas became the greatest prospect for companies. But since 2014, the world
knows that oil price is declining. Thus it makes many oil companies got some economic problem and need to cut a lot of cost, starting from production, exploration, drilling, until number of employees. Lately, companies require low cost for drilling onshore and offshore, for that reason, rig constructor needs to make their rig more efficient in every aspect.
From information above, we Espargo Corp. will design a rig that suits the most for this case. We call it MINERVA Rig. The following features are shown below: 1.

Consideration of choosing material for designing semi - submersible rig it is an essential basic to build up a rig for extraction and production in a long term and huge project. To ensure the drilling process we present ESPARGO RIG which constructed with Carbon Manganese Steel Plate . The carbon-manganese steels, whose
primary chemical components are carbon and manganese in addition to iron, thesubstance content in carbon steels is often increased for the purpose of increasing depth of hardening and improving strength and toughness and resistance of corrosion.
Carbon (C) : Manganese (Mn) :
High tensile Strength Increase hardenability
Phosporus(P) and sulfur (S ):
Undesirable compound
Copper (Cu) :
Corrosion resistance
Silicon (Si ):
Increase strength and hardness
Nickel (Ni) :

The Dual Ram Rig supports our ultimate objectives and helps us achieve i.a:
o Efficiency in the drilling operations; dual activity, offline pipe handling. o Safety; equipment pushed from drill floor by hydraulic cylinders rather than suspended by wire from top of derrick. No slip and cut. o Lower weight & lower centre of gravity; higher variable deck load. - Cost efficient maintenance

CIRCULATING SYSTEM MINERVA 17
HEX PUMP Based on that encouraging experience, we
developed the system as a stand-alone module to add to the existing hex pump control system. Slightly simplified, it consists of the following components: accelerometers (one per valve block), a proximity sensor
picking up pump speed and phase, a discharge pressure sensor, an embedded monitoring system (CompactRIO with NI 9234 acquisition
modules
for
powering
the
accelerometers and acquiring high frequency
data), signal processing software and alarm logics, software running on the CompactRIO monitoring system, and an HMI user interface.
Advantages: o Capture high-rate data (25 kHz sample rate) from all sensors during a short time interval covering at least one pump cycle o Bandpass filter the acceleration signals to minimize the influence from ambient pump vibrations o Analyze the timing signal to find pump speed and cam angle o Normalize the vibration levels through division by the median vibration level o Set a leak alarm if one or more of the normalized vibration levels exceed a specified threshold during a certain time interval
Based on the field experience of the new leak detection system, we concluded that our leak detection method offers many advantages over current practices, including the following: o High sensitivity for early leak detection and localization o Remote, continuous, and computer-based pump monitoring Increased safety through less human exposure
to hazardous environments o Multiple leak detection and localization (in hex pumps) o Reduced maintenance time and cost because leaky valve(s) are localized before the valve exchange jobs start.
19
CONTINUOUS CIRCULATION SYSTEM Basically circulation system are closely related with drilling fluid that has function to lift up the cutting from the bottom to the surface in order to prevent stuck, then drill fluid (Mud) is used to balance the reservoir’s pressure
in order to prevent the blow out. At last but not least the drilling fluid has to be circulated quickly to reduce the operational cost and accelerate the drilling processes.
Lopaka Natantis rig has installed the continuous circulation system to accelerate the drilling process and also to minimize the cost of the rig, continuous circulation system refers to the concept of allowing mud to the borehole
continuously while connecting the drill pipe.
Advantages: o Reduce drilling duration o Fewer stuck pipe incident
o Reduces reservoir and hole damage o Lower drilling cost o Increase production due to less reservoir damage o Reduce the possibility of kick
20
MUD CUBE The MudCube uses a combination of high air flow and vacuum pulled through a rotating screen (filter belt) rather than the high g forces and vibration used by the standard shakers to separate mud and solids. This technology is
proven to have higher levels of solids removal efficiency, which in turn reduces the volume of drilling fluid lost, minimizes the tonnage of waste generated, and raises drilling fluid performance, which all contribute to an overall reduction in cost.

SOLAR PANEL
Despite of using diesel as a prime mover, Lopaka Natantis also using solar panelas a secondary mover to produce additional power to supply electrical energy which is used for housing purpose. We use
SunPower as a solar panel in LopakaNatantis.Solar panels can convert 24.1% of solar energy to power, compared with around 17% for a standard solar technology product, making them the most efficient in the world. What’s more, SunPower has developed a robotic solar panel cleaning system to maintain optimum performance. This system is quicker and more efficient than traditional methods: it uses 75%2 less water and operates at night to maintain total panel efficiency during the day.
25
HIGH-ALTITUDE WIND TURBINE There is enough wind, but what is the most efficient way of using it? Ampyx Power is developing an Airborne Wind Energy system with a PowerPlane, a tethered aircraft that converts wind into electricity. Ampyx Power systems start where conventional wind turbines end. The PowerPlane moves at an altitude of up to 450 metres where the wind is strong and constant. PowerPlanes take off, fly and land autonomously from an innovative platform, by utilizing a vast array of sensor suites which provide the autopilot with critical information to perform the task safely. With these autonomous aircraft, 2 MW power can be generated, supplying 2,000 homes with sustainable energy.

A DP 3 system has an extended hardware configuration compared to a DP 2 system. The triple redundant DP controller is still used and a
minimum of three operator stations is required. There will also be three I/O units to interface components, as opposed to a double set of sensors typically used in a DP 2 configuration. A DP 3 system also needs a physically separate,
fire-safe compartment where one control computer, one operator station and one sensor I/O unit have to be located in order to comply with Class 3 requirements. Loss of position should not occur from any single failure including
a completely burnt fire sub division or flooded watertight compartment.
BRIDGE MATE DP3
41
Dynamic positioning requires the vessel to have a number of thrusters, or powered propellers, throughout
the vessel. These thrusters are located on the front and back, as well as both sides of the vessel, in order to maintain position from every direction. Sometimes mooring and dynamic positioning are used together to keep the vessel on position.
Additionally, with a dynamic positioning system, these vessels many times can stop operations and move out of the way of threatening storms, such as hurricanes and cyclones, further strengthening the safety of the offshore development.
