Abstract

ABSTRAK This research discusses the operability of vertical acceleration in the helideck. The experiment was carried out at the Maneuvering and Ocean Engineering Basin (MOB) facility of the BPPT-ITS Hydrodynamics Technology Center. The model being tested is the catamaran type with a scale of 1:36 to the original scale. Experimental testing using random waves with a Piersonmaskowitz spectrum with Hs = 2.5 and Hs = 6.37 m. The helideck only performs surge sway and heave tests. Meanwhile, numerical analyzes the effects of regular waves at heading 0 45 90 135 180 and obtained RAO for Heave, Roll, Pitch movements. For the analysis of landing operability at Helideck using the Olson and Marine criteria, where the limit of wave height according to Olson is obtained, namely for the incoming wave direction of 0, 90,180, it should not be done more than 3 meters of wave height, while for conditions 450 and 1350 should not be above 4 meters. . For the HCA category, the critical condition when the direction of the wave of 900 with a wave height of 2 meters. At an altitude of 4 meters is the limit of the wave direction 0 45 135 180.
双体船浮式起重机直升机甲板垂直运动加速度分析的实验与数值研究
摘要:本研究探讨直升机甲板垂直加速度的可操作性。实验是在bpt - its流体力学技术中心的机动和海洋工程盆地(MOB)设施进行的。试验模型为双体船型,比例为原比例的1:36。采用随机波进行实验测试,随机波具有Hs = 2.5和Hs = 6.37 m的pierson - maskowitz谱。直升机甲板只进行浪涌摇摆和起伏试验。同时,数值分析了航向0、45、90、135、180方向规则波的影响,得到了纵摇、横摇、俯仰运动的RAO。在Helideck上使用Olson和Marine标准进行登陆可操作性分析时,根据Olson标准得到了波高的极限,即对于入波方向0,90,180,不应超过3米的波高,而对于条件450和1350,不应超过4米。对于HCA类,当波浪方向为900,波高为2米时的临界条件。在海拔4米的地方,波的方向的极限是45 ~ 135 ~ 180。
