SPM(Single Point Mooring)

Generally, crude oil loading/offloading works are operated on the inner side of the harbors. But as the rate of oil transportation increases, conventional harbors as oil terminal contains the risk of marine collision accidents due to limited space of harbors and those incidents cause severe environmental pollution, when it comes to happen.

Our SPM is targeted for safe operation and offers risk-free and pollution-free alternative. Unlike normal ways of transferring of oil, SPM method accommodates Handymax up to ULCC (Ultra Large Crude oil Carrier) to be moored on the outer side of the harbor and enables vessels to have more spaces during on/off loading operation of crude oil.

This SPM oil terminal requires highly reliable safety system since it is very intimate with oil pollution in case of SPM damages or failures. Oceanus Turret CALM Buoy, which can satisfy customer needs and protect our environment, is designed and manufactured in compliance with Class CODE and international standard. We provide entire EPCIC work for SPM.

Overall SMR Procedure

SMR Scheme & Technique

Having selected the level of SMR, the tailored SMR technique (or techniques) has to be chosen to realize the SMR scheme. In most cases there are alternatives that would achieve this objective; although in many instances, particularly for local SMR schemes, the choice may be fairly obvious. The selection of SMR technique(s) requires: knowledge of the available range of techniques, including variants; their strengths and weaknesses; and an appreciation of other factors such as ease of design, building, offshore support and equipment requirements, local supply infrastructure, and etc.

A summary of the main SMR techniques available is presented in the below table.
