Offshore Bearing Systems Trelleborg Ridderkerk BV

To supply products to the Offshore Industry is challenging for any supplier. Products must be thoroughly and rigorously designed, manufactured, tested and documented. Often the requirements push the scope of current technology, the lead times are short and the delivery times are critical. Clients must have complete confidence in your ability to perform under these conditions. Trelleborg Ridderkerk is a leading global supplier of elastomeric bearing systems to major offshore projects. Each of these products is designed to perform to the client’s specified operating criteria. We are focused...

Jack-ups are provided with jacking systems for lifting and lowering the platform on the legs. Since years Trelleborg Ridderkerk designs and supplies rubber shock pads for these jacking systems. The shock pads have to absorb loads in combination with relative low compression stiffness. Compared to ordinary steel-rubber laminated bearings, shock pads are built up with relative thick rubber layers. In order to monitor the loads during the jacking operations we have developed shock pads with an integrated electronic load cell. Shock pads for jack-ups

Floating Production Storage and Offloading Facilities (FPSOs) are a workhorse of the offshore industry. Their service requirements include multidirectional loads transferred between the hull and topside modules as a result of wave action. The module support bearings must be able to resist large alternating movements in all three directions and large rotational movements in line with the FPSOs longitudinal axis. Trelleborg Ridderkerk designs and manufactures support bearings to match these exacting requirements. Module Support Bearings for FPSOs In 2003, Trelleborg Ridderkerk won the order...

Trelleborg Ridderkerk used its rich experience in elastomeric bearings for bridges and shock pads for platforms to design the special module support bearings. In total 3 types have been designed for the FPSO SeaRose, the so called B01, B02 and B03. The heaviest of these elements is close to ten tonnes in weight and can withstand a vertical load of up to 10,000 kN and a horizontal load of up to 3,500 kN. The design is based on a combination of rubber and steel to compensate a displacement of 75 millimetres. All bearings are steel plate reinforced in order to keep the stresses to an...

Andre anti-vibration mounts Since the early 1970’s Andre have utilised their expertise and experience to provide AVMs world-wide to many of the major gas turbine, generator, compressor and pump unit manufacturers for the isolation of structures from potentially damaging machine-borne vibration. Applications cover oil and gas exploration and production platforms, FPSOs, accommadation modules and helidecks. Andre AVMs are custom designed and consist of elastomeric bearing units located under the support skid. Design Features • Natural frequency of the isolated skid: Typically within the...

Leg Mating Units (LMUs) and Deck Support Units (DSUs) are a critical part of the floatover process, one of the key installation methods for offshore constructions. During a floatover a deck is transported from the fabrication site and installed onto a pre-installed jacket. The decks typically weigh several thousand tonnes and this load has to be transferred to the lower structure in a controlled and progressive process. DSUs are applied between the deck load to the pre-installed jacket. Leg Mating and Deck Support Units The heart of the LMUs or DSUs is the load absorbing elastomeric units....
