TT Talk - Costly pickings: the persistent accidental twin-lift problem
- crane operator error in not selecting a twin-lift mode or indeed in trying to lift with a fixed 40’ spreader;
- twistlocks not engaged properly;
- difficulty in observing what is being lifted, exacerbated by the depth of the hold and height of gantry cranes for the latest generation of container ships;
- override or disabling of the sensor system, either by the operator or the maintenance department (sometimes without informing the operational staff!);
- the ship’s manifest information being incorrect.

TT Club has previously reported on incident experience whereby containers have dropped from lifting equipment during handling operations. Recurrence appears, as previously, to have nothing to do with the intrinsic quality of the corner castings. The reliability of the lifting process is critical.
UN portable tanks (tank containers) have been used in the international supply chain to distribute bulk cargoes for many years. Having such a deep heritage in the insurance of the maritime containers, naturally TT Club has intimate understanding of the tank container sector, with a current insurable interest in around 53% of the global tank container fleet.
TT Talk - Mitigating the corrosion nightmare
Corrosion is a perennial concern for tank container owners and operators. The stainless steel construction is resistant to staining and corrosion, but may be vulnerable to pitting from certain cargoes or certain cleaning and maintenance operations. Visually minor pitting may conceal development of substantial or even catastrophic corrosion below the surface.
TT Club continually seeks to understand the risks faced in the transport and logistics industry, providing relevant and targeted loss prevention advice to operators as appropriate. This article focuses on the findings of recent analysis into the risks faced by container terminals.
