Opis:
With this optimization, the cargo will increase and the ship's revenue will also be more. The LCU ship that we know so far is a ship whose cargo is always above the main and the space under the main is unused Void Space. The purpose of this study is to determine the optimization value of the use of space under the main deck of the Landing Craft Utility (LCU) ships. method used in this study is a comparison with several previous ship approaches to produce evaluation results from the addition of loading space under the main deck and calculation of stability using computational software approximation. LCU design of under main deck space with a maximum vehicle value can accept a vertical moment of 2750 mm. With a structural strength of 13150 tons. A series of numerical experiments show that the proposed method can effectively produce a satisfactory LCU ship design optimization plan for ship owners.

Opis:
This paper discusses the mechanical properties of alternative wood substitute materials in the construction of small boats (jukung/cadik type). Jukung/cadik boat as a small fishing boat with a length overall 6,400 m, design beam 1,530 m, design draft 0.380 m, displacement 2,442 tons, wetted surface area 15.58 m2, the pressure acting on the submerged hull needed minimum material used has a strength of 0.0039 MPa or 3.92 kN/m2. The replacement material used is the HDPE blue drum scrap, which has an average thickness of 3mm, then made into two layers as laminate. The laminate process uses welding. The results of HDPE laminate material from these two layers are tested for tensile and compressive strength to meet the material strength requirements for small ship hulls. They were testing the strength of HDPE welded joints with type A1 specimens. Tension and compression of the two-layer laminate material was tested with specimens of type A2, A3, and A4. The tensile test results for A1 specimens obtained for welding tests are pretty good at 17.1 MPa, then the results of compression tests for specimen type A2, A3, and A4 on average are 23.36 MPa, which is greater than the need for the strength of the jukung/cadik hull.

Opis:
In northern Iraq, countless non-abuse stream valleys can be used to store water for a variety of purposes; domestic, supplementary irrigation, and recharging groundwater. Bandawaya is one of the stream valleys, which form the first perspective has excellent quality. The location of the suggested dam has been evaluated by hydrological and geotechnical studies. Geotechnical studies included measurement of all the parameters related to the rock mass classification for evaluation based on four classification systems, which are the Q-System, the rock mass rating (RMR), the geological strength index (GSI), and the rock mass index (RMi). The classification results indicated that the rocks of the valley are good for constructing a dam on them, with some weak zones that may affect the integrity of the dam, which the study recommended treating before starting the construction of the dam. According to preliminary studies on different dam’s heights the qualification demonstrates an excellent choice of the site. Four stream orders are recognized, dendritic pattern in the southern part of the watershed, and trellised in the northern part. Three heights assumed to the proposed dam 450, 460, 470 m a.s.l. with 640,764; 3429,787; 8,590,763 m3 storage capacity respectively. According to the Q-System, the RMR, the GSI, and the RMi, the rock mass of the study area is evaluated. The findings illustrate the excellent selection by geotechnical, hydrological, and engineering features of the dam place.

Opis:
Sediment samples were collected from the coastal area of the Petrochemical Special Economic Zone of Musa Bay. The samples were analyzed to determine the degree of hydrocarbon contamination and identify the sources of PAHs which were evaluated by employing the ratios of specific PAHs compounds and principal component analysis (PCA). The levels of TPH concentration in the studied area were relatively moderate compared to the world-wide chronically oil-contaminated locations. The concentration of total PAHs was lower than those in other parts of the Musa Bay but approached the NOAA sediment quality guideline value.
