Reference projects - Refinery construction

DLT are experts in the erection of heavy vessels using conventional cranage and specialist jacking systems. We have extensive knowledge of all available equipment and are able to advise on the most practical, economic and safe solution for your project. We have been involved in the engineering of many heavy lifting schemes inside refineries and the design and supply of specialist heavy lifting equipment to carry out these operations. We carry out this work for ourselves and for other heavy lifting companies, as well as acting as advisors to Client organisations. Recent examples of our work include………

DL-TS3000 Mk1 modular jacking tower system The DL-TS3000 Mk1 jacking tower system is owned and operated by DLT and can lift vessels up to 3000 tones and 150m high. It is able to self erect and dismantle and with the optional DL-TF1500 is able to operate without a tailing crane. It can operate unguyed up to 70m high in stormk wind of up to 40 m/sec. All components are transported in standard shipping containers for economic relocation between sites. Download duty chart>

------------------------------------------------------------------------------------- Formosa Plastics Plant, Taiwan DLT were responsible for the design, supply & operation of a modular jacking tower system that has so far been used to erect 58 vessels weighing up to 1,557 tonnes and up to 114.5m long. Formosa Plastics Plant, Taiwan, jacking tower system for erection of heavy vessels using strand jacks. The Formosa Plastics petrochemical plant in Mai-Liao, Taiwan, is one of the biggest refineries & chemical plants in the world. All the large vessels, weighing up to 1,557 tonnes and up to 114.5m long, have been erected using a modular jacking tower system designed and supplied by Dorman Long Technology. To date 58 vessels have been erected with the tower system with a combined weight of 54,000 tonnes. We have also provided site supervisors to oversee the majority of vessel lifts and have carried out vessel specific erection engineering. The jacking tower system uses up to 4 No DL-S580 strand jacks for lifting and 4 No DL-S105 strand jacks for guying and can be used in a number of configurations as shown below. The system is capable of being used without guys for the reaction of vessels up to 35 m tall and 1100 tonnes. Erection of 77m high, 760 tonne column Erection of multiple 30m high, 1100 tonne reactors using unguyed jacking tower that is skidded between vessel erection positions Erection of 132m high, 1350 tonne column using jacking tower in ‘U-frame’ configuration in which the vessel rises above the top of the tower and passes through a U frame at the top of the towers. Erection of a 780 tonne regenerator into the permanent support frame, with the jacking tower system mounted on the top of the frame -------------------------------------------------------------------------------------

2500 tonne strand jack tower system, China DLT were responsible for the conceptual and detailed design of this 2500 tonne lifting capacity modular strand jack tower system, specifically designed for the Chinese refinery construction market. The tower system is owned and operated by the No 4 Construction company of SINOPEC and has many new features including self-erection and luffing under full load. Sinopec FCC Jacking tower system for erection of petrochemical vessels. In 2002 we were engaged to carry out the conceptual and detailed design of a new modular jacking tower system for the Chinese refinery construction market, to be owned and operated by No 4 Construction Company of Sinopec. The system uses strand jacks for vessel lifting and guying of the tower and was designed with many new features, including: • Low level assembly using mobile crane and self-erect/dismantle to full height of over 100m • Tower luffing capability under full load • Integral base skidding system • Reduced sensitivity to ground settlement/rotation under load • All components readily transportable by road between sites The new system carried out its first lift in early 2003. It was used to erect a 92m long, 763 tonne vessel in a chemical plant on the outskirts of Nanjing, China. (see below). First lift Tower system during self-erection Tower system operating sequence: 1. Tower self erected to full height and vessel delivered over foundations 2. Vessel lifted using strand jacks 3. Vessel rotated and set down on foundations 4. Tower skidded clear of vessel 5. Tower self-dismantles to low level 6. Tower ready for removal by light mobile crane -------------------------------------------------------------------------------------

Heat exchanger replacement, Indonesia DLT were responsible fore the design, supply and operation of a 60 tonne capacity gantry to replace 2 No 60 tonne heat exchangers from deep within a steel framed structure on PT Peni’s site in Indonesia. Use of these purpose designed gantries in place of conventional cranage avoided the need to extensively dismantle the steel structure to gain access to the vessels, saving time and money.
