PT. Lintech Duta Pratama

PT. LINTECH DUTA PRATAMA is pleased to provide concept design, equipment supply up to construction of Jetty Structure project. Jetty Structure is a structure that stretch from the onshore to the water / sea at which vessels berth either at the head or alongside. Jetty structure is generally used as access and loading and/or offloading that provide a cost effective method for transporting large quantities of goods and raw materials. Jetty is one of the facilities provided within port designed area. In general, jetty structure consists of following parts :

Jetty Head and Jetty

The end and main structure of the jetty structure that equipped or designed for vessels berthing and mooring.

Access Bridge

The part of jetty that connect the onshore and main jetty structure. Access bridge is not equipped or designed for vessels berthing and mooring.

Dolphins

Marine structures that extends above the water level and is not connected to shore. Dolphins are commonly used in combination with piers or wharves to reduce the size of piers. Dolphins are generally divided into two types, namely breasting dolphins and mooring dolphins with several functions as followings

Breasting dolphins

• Assist in berthing vessel by taking up some berthing loads portion
• Protect the pier structure from possible impact of vessel
• Could serve as mooring points as well to restrict longitudinal movement of the berthing vessel

Mooring dolphins

It is used for mooring only and for securing the vessels by using ropes. They are also commonly used near pier structures to control the transverse movement of the berthing vessels. Mooring dolphins are single structures designed to take care of the tension on mooring line. In most cases there are provided to take care of the longitudinal load due to slight surge of the vessel while moored.

Fender System

A bumper used to absorb the kinetic energy of vessel berthing against a jetty. Fender system is used to prevent damage to both vessels and berthing structure. Fenders have high energy absorption and low reaction force. Fenders are typically manufactured out of rubber, foam elastomer or plastic. Rubber fenders are either extruded or made in a mold. The type of fender that is most suitable for an application depends on many variables, including dimensions and displacement of the vessel, maximum allowable stand-off, berthing structure, tidal variations and other berth-specific conditions. The size of the fender unit is based on the berthing energy of the vessel which is related to the square of the berthing velocity

Bollards

A sturdy, short and vertical post used to hold the vessel line while berthing. It is usually constructed of cast steel. Special care need to be considered before installing the anchor bolts of bollards to avoid clash with reinforcement, wiring, pipe sleeve and etc.

Considering the general process above, PT. LINTECH DUTA PRATAMA here with stated our capability in designing, manufacture, supply and construction of the Jetty Structure to meet the customer requirements or custom design.
