The ROC must be set in totally negative buoyancy to ensure it crawl on the seafloor. This project is aimed to design and development of the low cost ROC for pipeline inspection. The 3D model design is developed using SolidWorks where certain parameters such as the centre of gravity and force can be obtained. An Arduino UNO, and H-bridge L298N have been used to process the signal received from the PS2 joystick controller, which also work as the controller of the system for ROC. The investigation and analysis of ROC in terms of manoeuvre, stability and obstacle avoidance also describe in this paper. The ROC can crawl on several surfaces like floor, sand, and grass surface. For underwater test, the waterproof test is done to ensure the electronic component are sealed tightly so that there it will last long. Next, the time taken for ROC to complete 2m distance of forward and reverse movement in the laboratory tank test and pool test is compared. As a result, the ROC can crawl until 0.065m of wooden plank's obstacle. In addition, the sliding test is one of the obstacle and its limit is 51.48°.","PeriodicalId":137478,"journal":{"name":"2017 IEEE 7th International Conference on Underwater System Technology: Theory and Applications (USYS)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127890536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 1995 STCW-F Convention sets the certification and minimum training requirements for crews of seagoing fishing vessels of 24 metres in length and above. Sabah and Wilayah Persekutuan Labuan fishing industry among the highest contribution for Malaysia fishing industry in term of catch value percentage. The objective for this research is to identify the correlation relationship between issues (variables) faced by Malaysian fishermen on the implementation of STCW-F using Bivariate Analysis. The analysis in this research is represented by individual/fisherman from Sabah and Wilayah Persekutuan Labuan. The scope of this research is suggested to focus especially at East Malaysia. The result identify correlation each variables the issues faced by Malaysian Fisherman on the implementation of STCW-F. The correlation relationship of every variables are key factor to implement the new law that has been produced by IMO in Malaysia. The findings will give clear picture to the government about issues faced by fishermen implement STCW-F convention. Implementation of STCW-F is important because government can control and prevent accident/casualties among fisherman as a result of safety course that has been offered by STCW-F is a complete set for all fishing vessel personnel.","PeriodicalId":137478,"journal":{"name":"2017 IEEE 7th International Conference on Underwater System Technology: Theory and Applications (USYS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128871201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
