Weight Estimated of 230' X 64' X 14' Deck Cargo Barge

This week i learned how to calculate the Steel Weight Estimated of 230' X 64' X 14' Deck Cargo Barge based on the construction plan. First i have encounter problem of how to calculate the quantity of the bracket and stiffeners, but later i was assist by my supervisor as he has much more experience than me in this.

7th Week, Stern Supporting Pole design

This week i was required to design a Stern Supporting Pole . The shape of the pole was first draft in solidworks. There are Api pire, Ellipse plate, bracket and etc.

In solidworks, there are 2D sketching and 3D sketching. in this design, 3D sketching is needed draft this design. After finished drafting, all the part was extruded and completed the design.

Analysis was done by using Simulation Xpress feature in solidworks by added fixture, material, load. Graph of Von Mises Stress was generated and the factor of safety also calculated.

After finished the analysis, the drawing was produced in form of top view, side view, front view and also isometric view. All the dimension was attached on the drawing.

The 6th Week of Trainning

This week i was assigned to design a ship Base based on the dimension refer from Grade One Marine Shipyard. Ship Base basically used to support the hull of the ship to park on it. I sketch it on the solidworks software and then extrude it to the 3D parts. The analysis was then done by the Simulation Xpress. Drawing was also be produced and printed in A3 and A4 format for different purposes.

Visit Grade One Marine Shipyard

Last Week, 3/5/2010 - 6/5/2010, Mr. Johan, W.M. Putra and i was on duty to visit Grade One Marine Shipyard Sdn. Bhd. for inspection of the progress of work according to the schedule on vessel Masindra 13. Transporting the Chrome Liner and seals after machining to the shipyard was also part of the mission. The chrome liners act as rubbing surfaces for the rubber lip seals but grooving from frictional wear has been a problem.

Grade One Marine Shipyard Sdn Bhd was located at Lumut Port, Perak. It takes around 4 hours drive to reach there. i met En. Azlan , the project supervisor for the detail of their work on vessel Masindra 13. The vessel have few area to be repair such as hull repairs at Bulkheads, Plates, Hull sweep blast and paint, gauging (check hull thickness under engine room), chain locker cleaned and paint, Machinery repair such as first line valve, sea chest and sea chest strainer check, rope guard install, stern tube flushed, chrome liner, chrome liner seal ( for oil and water) & oring replace and install.

After understanding all the work that have to be done, they have prepared a guest room for us to rest and meeting inside the room. After work, we go to rent the hotel at Oriental Star, Lumut for 3days.

I have learned that their company is well organized, every department has their own duty, and the safety and health was being focused. Every one must wear safety shoe, safe helmet and smoking is prohibited.

The next day i was trying to get the dimension of the ship-base, stern supporting pole, hull supporting stand. I try to understand the design by consulting the project supervisor, Mr. Azlan to give me more information about the design.

I've gain a lot of experience there few days from the workplace and i think this is the opportunity for me to learn as much as i can.

Delta Plate Design & Analysis

This week i was told to design a Delta Plate. Delta Plate is a triangle Plate which has 3 holes each side used for ship towing purpose. Delta Plate must be design to sustain the tension stress without crack. By using Solidworks, i was able to perform the design and analysis.

Ship Survey On Barge Viva 7

Today i was assigned by my supervisor to survey on Barge Viva 7. Since She's in the middle of the river, a small boat is used to transport us to the barge driven by Captain Dai . I was responsible to measure the dimension of the barge such as Length Overall (LOA), Breath etc. Thickness Gauge was used to measure the thickness of the steel plate at 40 most potentially deformed spot. The value was recorded in the table.

2nd Week Of Internship

I was assigned by my supervisor to assist my colleague, WM Putra to check for the condition of an air compressor at Masindra Langkawi supply vessel. After consult severe mariner, i found that is the piston problem. Then we order from our supplier from the machinery shop to find the same type head. The 10hp air compressor head was replaced by a 7.5hp compressor head because lack of stock.

After installed the new head of the air compressor helped by the seaman, the rev was too high and generate too much heat. Then the air compressor was modified to a smaller size pulley to slower down the rev speed. Therefore the belt was subject to change since the length is different then before. After everything serviced, the head must be align with the motor.

I learned about how to repair and fixed the air compressor this week and also continue my study about Maxsurf.

1st Week Of Training

Through out this week, i was told by my supervisor to read more books related to marine field to gain more knowledge about shipbuilding. Therefore i referred to SHIP CONSTRUCTION by D J EYRES. This book thought me about the basic design of the ship, development of ship types, materails and strength of ships etc.

Besides, i was introduced to a ship design software, Maxsurf for hull design. Maxsurf provides fast, flexible and intuitive modelling of all types of hulls, superstructures and appendages. An unlimited number of trimmed NURB surfaces can be used to model any vessel from yachts to workboats to the largest ships.

The core of the Maxsurf range, the Maxsurf design module, provides the naval architect with the design tools necessary tocreate fair, optimized hull forms quickly, accurately and with limited training time. Any number of NURB surfaces can be joined, trimmed and manipulated to create a complete model ready for hydrostatic analysis or construction detailing.

A range of commands provide direct interactive manipulation of the surface shape by mouse or keyboard. Maxsurf provides automated transformation of the hull form to match desired dimensions and hydrostatic properties. Control points can be dragged with the mouse, adjusted numerically, or manipulated by a range of fairing commands.

I was able to modeling a simply ship hull by going through the tutorial provided by the software. I found out that it is challenging and interesting for me to learn more about it.

1st Day Of Trainning

The first day is kind of excited feeling for me as i have experienced different environment of workplace. It is totally not the same from which i worked before at Unitech Shipbuilding Sdn Bhd. I was introduced to my general manager and fellow colleague, then Wan Putra, the marine designer explained all about how is the company operate.

I was assigned by my supervisor, Wan Johan to do some research on Maxsurf sofware and play around with the software. I started to read the tutorial about Maxsurt and found out that it is challenging.

Company Profile

Established in 2008, Avant-Garde Shipbuilder Sdn Bhd has developed a fine-tuned and successful synergy between innovative technical solutions and solid marine construction design, resulting in new dimensions in detailed shipbuilding production.

As a developing country, Malaysia has endless potential to emerge as a dynamic player in the vast marine industry in terms of shipbuilding, ship-repairing, support services and leisure industries.

Unfortunately, the progress of these lucrative industries is stalled by countless challenges, particularly the stiff regional and global competition. Not only does Malaysia lack of technological advantage to compete on a level ground with pioneer shipbuilding nations such as Japan and Korea, they also do not have the luxury of favorable economies of scale and readily-available cheap labour as China does. Hence, Malaysian shipyards are still developing to build and service more sophisticated seafaring vessels.

Malaysia lags far behind in the international playing field, despite of its 60 years of commendable experience in the marine industry. Therefore, it is crucial for the local industry to focus collectively on one strategic goal – to boost Malaysia to its full maritime potential and this is precisely where Avant-Garde Shipbuilder Sdn. Bhd. comes in, with the initiative to ignite the local maritime scene.

Initially formed under the associated shipping companies, Viva Omega Sdn. Bhd. and Masindra Shipping (M) Sdn. Bhd., the team was assigned with instant services for variety of marine fabrication works. In recognition of the team’s capabilities, both shipping companies elevated the team to be one of the official shipbuilding companies, granting them full support in their venture to new heights. Fueled by refreshing talent and an insatiable desire to achieve milestones in maritime history, Avant-Garde Shipbuilder Sdn. Bhd. evolved phenomenally from ship-repairing to shipbuilding and various degrees of marine constructions. Their acceleration in technical progress has emboldened them to explore more challenging fields such as ship design and hydrostatic report.

As they tackle projects from the veteran forwarding companies, skills and techniques are honed to perfection, enabling the company to raise their standards.
