AIM Control's heavy lift technical calculated by loading master in safe for one tug boat load on board of vessel under AIM Control Supercargo Experts supervised:

AIM Control’s heavy lifting loading master and experts have been requested to carry out calculations on lifting gear arrangement in order to load a 545 tug boat by means of ship’s cranes consisted in two (2) deck cranes of 400t capacity each.

AIM Control’s Heavy lift technical loading master's calculations were based on the drawings prepared by AIM Control Technical Department (attached herewith) and further details discussed over the phone with Dr Capt. Nguyen Te Nhan and/or Master Mariner Nguyen Thuan Nghia / Nguyen Sy Huy and technical Port Captains from AIM Control’s Vietnam Head office.

We are in a position to report as follows:

Summary and Conclusions

Accordingly, the load in aft hook equivalent to 368 t will be distributed in two sling legs with a load of 205 tons tension each. Each leg connecting the hook with the respective spreader end will be supported by 2 grommets steel slings 10m length and 114 tons safe capacity each.

The load at the heaviest end equivalent to 368 t will be supported by 4 polyester grommet slings 25m long and 100t safe capacity each attached to an spreader of 400 t SWL.

The total load equivalent to 575 tons will be supported by 8 polyester grommet slings 25m long and 100 t safe capacity each.

Having considered that the tugboat cross section profiles are not available at present it was discussed and agreed with the Capt. of AIM Control at the site of loading that at all times the slings and spreader will be maintained clear from the tug accommodation block.

From information made available it appears that the rigging lay out described on the attached drawings should be considered adequate and safe provided all equipment including ship’s gear is duly certified by recognized organizations and is found in good conditions of maintenance.

This Report is based on facts presently known to the attending surveyors and is issued without prejudice to the rights of whom may concern. The right to amend or supplement this Report should additional information be made available is reserved.
