Abstract

Crude oil contains mixed of hydrocarbons, the most commonly found molecules are alkanes (paraffins), cycloalkanes (naphthenes), aromatic hydrocarbons, or more complicated chemicals. In the process of taking crude oil in subsea pipeline system with depth 1200 meters, the contents of crude oil like sulfur, paraffin, asphalt could deposit in the wall of the pipe because of the different temperature between crude oil and wall of the pipe. The deposition can make blockage to the pipe and cause crude oil flow to be slow or stop. In this bachelor thesis, will be design double walled pipe for Subsea pipeline system with depth 1200 meters and simulation double walled pipe to knowing the impact of double walled pipe to crude oil flow in Subsea with depth 1200 meters. Based on the simulation that has been done, using double walled pipe could stabilize the temperature between crude oil and wall of the pipe. It shows that the average of temperature decrease using double walled pipe is only 0.125 K for 12 meters. So, it could get the conclusion based on the simulation of double walled pipe that the impact to crude oil flow is there’s no blockage in the pipe and the crude oil flow will steady.

Abstract

RBI analysis for heat exchanger tube has been explained by API 581. Two types of PoF determination using statistical data is provided to determine the PoF category. Both Weibull parameter and generic failure frequencies are the methods that will be analysis in this present study. PoF determination using Weibull distribution gives the exponential value of PoF in a certain of time. This method only consider failure modes and the failure rate of heat exchanger tube without considering possible active damage mechanisms in the tube. However PoF determination using generic failure frequencies gives more complex consideration. It considers not only failure and possible active damage mechanism, but also the effect of management system facilities of the heat exchanger on the integrity of the plant.

Abstract

Modification of single-fuel diesel engine into dual-fuel diesel engine has been done by researchers to solve the problem of depletion petroleum reserves. Even the problem petroleum reserves are projected to be exhausted in the next 50 years. Gas-Oil fuel engine focus on solar-CNG as a fuel. Explanation of the difference in the fuel ratio of diesel engines with Gas-Oil fuel diesel engines has considerable differences. The factors that are discussed here are the factors of mixing air and fuel. The amount of fuel in the Gas-Oil fuel diesel engine causes an increase in the gas fuel mass flow rate (CNG), although with the addition of fuel gas, the mass flow rate of diesel oil is reduced. In this paper, the Gas-Oil fuel engines research and development fueled using solar-CNG are highlighted to keep the performance of the engine. Modification focused on air intake valve to give maximum turbulent flow ratio and effect on increasing Gas-Oil fuel engine performance. The high activities for future Gas-Oil fuel engines research and development to meet future Gas-Oil fuel engine solar-CNG is recorded in the paper.

Abstract

Turbulent flow in the combustion chamber affects the combustion process which also affects the engine performance. The turbulent flow intensity can increase the duration of combustion, but too much turbulent turbulent flow leads to a tap. In addition, turbulent flow also contributes to the gas-water mixing process. There are two types of turbulent flow that occur inside the machine, which is a current vortex and a falling current. The current whirl is better known as the swirl flow and the falling current is better known as the tumble flow. The fluid flow in the combustion chamber can be adjusted by optimizing the engine components and developing the engine design. A review has been made of the vortex and Tumble flow on a luminous spark machine and its effect on turbulence and fire propagation. From several journals available to create tumble and swirl streams in the combustion chamber, they use modifications to the intake valve by adding vin to create a swirl stream and adding a mask to create a tumble stream. to know the experiment was successful or not, first modeling and then perform simulation using CFD Ansys Fluent. for the variables choose 3mask, 4mask, and 5mask (for addition of mask) which later dilih air flow formed by the addition of mask.

Abstract

Strength analysis of hull structure of marine renewable energy is crucial. The hull structure must be able to whitstand the harsh environmental load such as wave, wind and the weight of the payload and the structure itself. This paper analyzies the structural hull strength of marine current turbine platform. The platform is held by 4 mooring lines in 200 m water depth. The hull material is AISI1050 with yield stress 530MPa, the analysis consist of stress analysis which consider the dynamic motion of the platform due to wave, current, win and mooring line tension. The dynamic motion shows the maximum gravity acceleration is 1.3496G. The gravity acceleration creates additional loads due to weight multiplication of payload and structure. From the dynamic analysis using numerical software, the maximum mooring line tension due to dynamic analysis is 300.74 kN and this tension will creates stress in the moring line connection structure in the platform hull. The maximum stress of the is 126.045Pa, The mooring line tension is the highest loads compared to other factors such as weight. The safety factor of the structure based on the analysis is 4.2 which can be calculated by comparing the yield stress of the hull material and the maximum stress occurred due to dynamic load.

Abstract

Indonesia is a big country having big population, huge area and huge Exclusive Economic Zone area. For world harmonized growth, it is quite important to realize steady economy growth on Indonesia. Growth of Indonesia’s shipbuilding industry specifically is an important part to achieve Indonesia’s maritime vision, but by far as for the shipbuilding market, 3 major countries, China, South Korea and Japan have obtained almost 100% share, which means it is quite difficult to increase the world share. In the volatile marine world, fluctuating oil price often affect production capacity, and investment decision is hard to get with TOP management. Indonesia shipbuilding industry has big mission under severe management and environmental condition. We clarify basic dilemma / conflict inhibiting the growth of Indonesia shipbuilding industry under assumption of severe management environmental condition, with Theory of Constraints (TOC). The basic dilemmas are solved by erasing the reason of existence of opposite activity and the Indonesia shipbuilding ever-lasting development logic is proposed with the solution of basic dilemma.
