Marine loading arms are special equipment for loading and unloading fluid materials cross over the wharf and tankers, with pipelines connected by swivel joints, and supplemented by supporting structure, and other accessories such as control systems required by customers. It is mainly used for transferring the fluid such as petroleum, LNG, LPG, chemicals, gas, oil, etc between the pipe system and the oil tankers. It is mainly consisting of pipeline, swivel joint, spring balance system, flange, vapor cone, level probe, vacuum breaker valve, drop tube end deflector, coupling, etc. Kohan Leel Leyan (KLL) Company can install any type of marine loading arms and save lots of time and budget for its customers. Our expertise has no borders in this regard.
According to the features of service liquid, different temperature, and clients’ special request, the pipeline material can be carbon steel, stainless steel, and heating trace; and the operation mode can be designed as manual or electro-hydraulic control as per nominal diameter, types, load requirements. During the fluid transmission process, the arm can move with the drift range of the ship tanker. It can also be set with an acoustic-optical alarm device, to provide acoustic-optical alarm through travel monitoring system in case the pipe drifts beyond the specified operating range.
Working pressure: 0.6-4.0Mpa
Working temperature: -196~250℃
Nominal Diameter: DN100-DN600
The design depends on different requirement and environment, including tidal difference, vessel tonnage, service liquid, nominal diameter, pressure, and environmental data (include max. Wind speed, temperature and earthquake loads).
Unless specified, our environmental design parameters are as below:
Wind speed at standstill (stowed) condition≦30M/S
Wind speed in the operating condition≦16M/S
Earthquake resistance parameter 0.3G
