FULLY LOADED: Type 171 Vessel MV Lisa Shows Some Strength04. March 2021
Sometimes projects seem like everyday business at first sight – but, when we take a closer look, appearances can be deceiving. When SAL Engineering’s client Bedeschi approached the team with a shipment of four ship loaders for the OTEKO project in Taman, Russia, the complexity of this effort presented a one-of-a-kind engineering task.
The engineering scope for this project was pretty clear and upfront: Safely load, transport, discharge, and install the four partly dismantled ship loaders. One per shipment,” explained Florentin Edler, Project Engineer at SAL Engineering, and continued: “But to accommodate all parts of each ship loader on SAL’s Type 171 vessel MV Lisa, SAL had to make use of every centimeter of space available onboard. On top of that, the so-called “trailer front” presented an interesting challenge.
Due to the shape, size, and weight of the “trailer front”, it was necessary to find a solution to safely hook-on the cargo, load it on board and disconnect the rigging afterward without damaging the cargo. Mr. Florentin from SAL elaborates — “We decided to make use of the “trailer front’s” wheels to ensure smooth operations. We installed rails on the weather deck of MV Lisa and a special onboard pulling configuration using the mooring lines to be able to easily move the “trailer front” after loading. We literally sled it out of the rigging.”
The loading procedure was carried out in four steps:
Step 1: Prepare the rigging (consisting of a traverse, grommets, shackles, and water bags as well as compression bars as a counterweight).
Step 2: Move the cargo into the rigging by SPMTs.
Step 3: Swing the cargo aboard.
Step 4: Safely disconnect the rigging by pulling the cargo out using the onboard pulling configuration.
The vessel’s maximum lifting height was reached while loading the “trailer front”. The cargo and rigging were very close to the vessel’s structure, and the team had to make sure that the cargo was moved very precisely. Waterbags were not only used to keep the rigging leveled and to be able to hook-on, but also to level the cargo and ensure sufficient stability of the vessel.
It took about eight days, three tandem lifts (tripper, gantry, gantry boom), and two single-hook lifts (trailer front, trailer rear) to safely load all cargo on board MV Lisa.
Two ship loaders have already arrived safely in Taman and were installed successfully. The other two shipments will follow in 2021. SAL Heavy Lift is Project Logistics Alliances Heavy/Project Cargo Carrier partner.
About the OTEKO Project:
The OTEKO project in Taman (Russia) involved supplying a fully automated coal export terminal with a total aggregated capacity of more than 50,000 tph on six loading lines. Bedeschi Russia will actively contribute to the project management of the new OTEKO project in Taman. The supply includes bucket wheel stacker reclaimers, several km of conveyors, and ship loaders. The system allows for the blending of different types of coal. SAL Heavy Lift’s involvement in the project consists of transporting four ship loaders from Turkey to Russia.
